Pentair Residential Filtration Raising Prices

Pentair announced last month they will be raising prices on all of their products on January 1, 2011. The percentage increase varies depending upon the product group or groups you purchase. Unfortunately, we will have to pass on these increases. Since we will be taking an end-of-year inventory, we need to ship by December 22, 2010 to hold the current price. Please look at your inventories of:

  • Fleck valves and parts
  • Autotrol valves and parts
  • Aquamatic valves and parts
  • Structural Tanks

and plan accordingly.

Aquamatic Valve Page Added

A separate web page,, was added to the Res-Kem website dedicated to AquaMatic diaphragm valves, AquaMatic Stagers and Controllers. So the page is easier to find, Res-Kem also improved the navigation of our website.

On the web page we have AquaMatic ordering guides, technical drawings of these Diaphragm valves and the Stager/Controls. The stager/controls are used to operate indutrial water softeners, multi-media filters, sand filters, carbon filters, etc. We also videos explaining how to determine what valve you have and how to repair them are posted.

Condensate Polisher ROI Presentation

Reuse It – Don’t Lose It! The Economics of Condensate Polishing was presented at the GlobalSpec Industrial Processing virtual tradeshow on August 25, 2010. It is a rather long presentation so we posted in two pieces on YouTube.

Abstract of Presentation:
In today's environment of economic pressure and high energy costs, engineers are constantly asked to do more with less. A condensate polisher helps meet this challenge. Condensate polishers:

  • Save energy by reclaiming heat normally sent to drain
  • Save water by reducing boiler blow down
  • Reduce water treatment chemical usage

This presentation will use real world examples to show how condensate polishing reduces fuel consumption and minimizes water side fouling in medium- and low-pressure steam plants typical of the food, beverage, and chemical process industries.

New Water Treatment Technology from Stanford University

In the article High Speed Water Sterilization Using One-Dimensional Nanostructures, silver nanoparticles and carbon nanotubes were used to make a cotton fabric which kills bacteria by applying a low voltage across this conductive material.

The research was completed at Stanford University.

The electrical current that helps do the killing is only a few milliamps at 20volts. The power can be supplied by a small solar panel or a couple 12-volt car batteries. The electrical current can also be generated from a stationary bicycle or by a hand-cranked device.

The full paper can be purchased from the American Chemical Society

Fleck and Aquamatic Valve Service Training

On July 27-28, fifteen of Res-Kem's service supervisors and technicians attended a training program on servicing Fleck valves and Aquamatic valves. These people represented the Eastern Service Region and cover areas from Maine to Florida as far west as Pittsburgh.

From this training program, Res-Kem now has additional coverage for softener and filter install, start-up and repair throughout the Eastern Region.

We were fortunate to again have Dave Smith from Pentair to lead the education on the features, maintenance, and repair of Pentair Fleck light industrial and commercial valves. Dave gave a hands-on trouble-shooting and repair training program on Fleck valves. He had the Pentair Fleck 2850 and Fleck 9100 valves on hand so each person could tear down and rebuild each of the valves.

Res-Kem Loses $70,000 Water System Equipment Job

Our service group so successfully helped a food manufacturing company they no longer needed the new system we had quoted for about $70,000!

The System:
Customer has an older dual, 40 cubic foot parallel operating nitrate system required for manufacturing their food products. The normal flow rate is 80 to 85 gpm. The estimated age of the system 15 to 20 years, resin was in service for 10 years but was recently tested and found to be in shape to run another 6 to 12 months. They were in the process of gathering quotes for replacement equipment because they were experiencing low flow, 20 to 30 gpm, reason unknown, from unit #1.

The Problem:
On Tuesday, June 1, the #1 unit failed reducing the product flow to 5 to 10 gpm. As stated above, the normal flow rate is 80 to 85 gpm in a properly operating unit. We were contacted to see if we could service the unit but they could not be down longer than 12 hours due to production demand. They had no information on the system so we didn’t know what type of internals were in the vessel, but believed they were manufactured of black iron.

The Solution:
Res-Kem came on Wednesday, June 2 with two of our installation technicians to service the nitrate removal system. They vacuumed all the resin, gravel support bed but also encountered either anthracite or activated carbon. The internals were found to be manufactured of Schedule 80 PVC and in good condition. One of the technicians backwashed the system prior to refilling the tank and found no blockage within the distributors.

The new resin, Purolite A-520E, was picked up at Purolite by our Res-Kem truck and delivered to the customer the same day of the service. The customer and Res-Kem technicians decided to refill the tank and place it back into service. This was done and the system was operating at 85 gpm.

Start time 8:30AM – Completion 2:00PM
Would have been sooner but they had to bucket the resin into the tank because we could only get a super sack of resin from the manufacturer, due to the urgency, and they had no water pressure to educt the resin into the vessel.

The Bottomline:
They are thrilled with the service and limited downtime and we are now doing the #2 unit, but they are delaying the purchase of the replacement system.

Industrial UV System Pricing

The Res-Kem web site regularly receives leads for industrial, commercial, residential, and municipal ultraviolet water purifiers. Res-Kem has found that a standalone UV system has become a commodity. With this in mind, Res-Kem will only quote industrial, commercial and municipal UV systems when there is other equipment is being sold.

Examples are a UV system used in combination with rental deionization and filtration systems, or a UV system as part of our modular ultrapure water (UPW) system.

Softener Service at Power Plant in New Jersey

After reviewing our blog posts over the past 4+ years, I realized we have not talked much about our site service team. Our normal service area is in New Jersey, Eastern Pennsylvania, Delaware, and Maryland. On a case-by-case basis we have gone substantially further.

At a power plant in coastal New Jersey, a triple water softener system needed to have a media exchange. Each steel vessel has 20 cuft of softening resin. Res-Kem brought our trailer mounted vacuum.

Res-Kem trailer mounted vacuum for removing virtually all ion exchange and filtration media.
Services Provided:
Manned by two Res-Kem service people, the entire process of resin removal, underdrain inspection, and refilling took only 5 hours to complete from start to finish. "We could have been done about 1-1.5 hours sooner, but we couldn't shutdown all three units at once" said Joe Urbans III Res-Kem lead rebed technician because we needed to work around the plant's operation.

Our sales representative at the site stated "The Res Kem team was extremely professional! They executed all of the work safely, they worked quickly and efficiently - regularly checking in with the customer. The station engineer was very pleased with the work".

Nalco Acquires Res-Kem and General Water-Denise’s Story

On April 1st, I was fortunate enough to have sold my company, which I have been building for over 26 years, to Nalco Company. We are a wholly owned subsidiary now and our official name is Res-Kem LLC although we will continue to go by Res-Kem General Water.

As with every privately held business in America it is imperative to have a succession plan in place. As responsible business owners, my business partner and husband Bob Hader and I developed a business and team that would continue to thrive whether or not we are able to work. The team of people who work at our company are the best at what they do and I’ve worked hard to make sure no one was irreplaceable, including me.

I know things don’t always go as planned. I wasn’t looking to sell the business, we had a great 2009 in spite of the recession, but we were at a point where it was time to consider the next steps. These steps always include investing money in the business and it was time to consider all of my options. During the past year I’ve explored all the options and and was lucky enough to have been approached by Nalco during this evaluation.

My goals were to:
1. Continue to grow the business and secure the employment of my co-workers. As a family business, my coworkers include two brothers, a nephew, and many people who are like family. Those of you in small businesses know what I’m talking about.
2. Continue to take care of all of customers in the same fashion. We have a reputation to uphold. We are a business to business company but most importantly we’re a people company. We work hard for and like our customers.
3. Expand the company so rewarding manufacturing jobs will be available for the next generation.
4. Sell the company to people who would like for me to continue operating it. I may be in denial about my age, but I’m still not old enough to retire!
5. Make a deal with people I like – I had to like the people I would sell the company to.

So here’s the bottom line. I have accomplished all my goals and am excited for the future. As I said before the acquisition, we are not a chemical company. We distribute, service, and assemble water treatment equipment including service DI. I want to assure each of our customers using a different chemical company that we will continue to do business as always and not be bringing in the local Nalco rep. We are simply doing for Nalco the same things we’ve been doing for years – supplying equipment, services and SDI.

New Water Treatment Techology

In WaterOnline, one of the newsletters I receive, there was a synopsis of an article published in Nature Nanotechnology on March 21, 2010 entitled "Direct seawater desalination by ion concentration polarization" by Sung Jae Kim, Sung Hee Ko, Kwan Hyoung Kang & Jongyoon Han.

In the Water Online Article, it describes "A new approach to desalination being developed by researchers at MIT and in Korea could lead to small, portable desalination units that could be powered by solar cells or batteries and could deliver enough fresh water to supply the needs of a family or small village. As an added bonus, the system would also remove many contaminants, viruses and bacteria at the same time."

In the actual abstract of article in Nature Nantechnology, it states "A shortage of fresh water is one of the acute challenges facing the world today. An energy-efficient approach to converting sea water into fresh water could be of substantial benefit, but current desalination methods require high power consumption and operating costs or large-scale infrastructures, which make them difficult to implement in resource-limited settings or in disaster scenarios... Rather than competing with larger desalination plants, the method could be used to make small- or medium-scale systems, with the possibility of battery-powered operation."

In the "Next Big Future Blog", there are some excellent drawings extracted from the journal depicting how the process works.

Custom Manual Water Softeners Shipped

Last week, we shipped two custom water softeners. The customer was using the softeners to treat the water feeding plant safety showers. Res-Kem has the flexibility to take our standard industrial water softener designs and modify them to meet a specific customer's requirements for virtually the same cost as our standard systems.

For example:
The plant has strict explosion-proof requirements. Even with the multitude of standard designs Res-Kem has using Fleck, Autotrol, Aquamatic, and Bray valves and Aquamatic electro-mechanical or Allen Bradley controls, we collectively determined the cost to accomplish an automatic, explosion-proof design was too great for the application.

So, each system is a single tank unit with manual regeneration. The face piping was Schedule 80 PVC. The valves were true union ball valves. Polyethylene lined composite fiberglass tanks with laminate glass exterior, 150 psi ASME code. Also, the customer requested a pressure relief valve for over pressure protection.

Triple Greensand Plus Filter for Iron and Manganese Removal

A triple Greensand Plus filter for iron and manganese removal was assembled and shipped today. This skid-mounted system will be installed to treat the water for a small community water system in the Poconos operated by a large private water utility company.

Triple Greensand Plus Filter for Iron and Manganese Removal after assembly at Res-Kem Corp.
The system operates in a parallel arrangement with three skid mounted, Greensand Plus filters with optional interconnecting piping and isolation valves. As specified, Bray butterfly valves with electric actuators are used. To match standard practice at the utility, a Modicon Premium PLC with Wonderware Windows CE operator interface panel will be used. Each tank is epoxy lined carbon steel with an epoxy exterior, 150 psi ASME code. Face piping consists of Schedule 40 black pipe and fittings. Regeneration initiated by either high differential pressure or timeclock.

Blogger Transition from FTP-Step #7

While everything looked fine at first, it turns out there was one more big problem we had in our transition from our own hosted blog using FTP with Blogger to a Blogger hosted blog. The numerous pictures we had in our old posts were not showing up in our Blogger hosted version. It turned out a step 7 required to make the final transition.

After searching Blogger Help and hunting around we found this paragraph at the bottom of the page:

"This situation may arise if you originally published your blog via FTP and then switched to using custom domain publishing. Images originally posted to your server do not get transferred over to Blogger when you do this, so you may want to move them all to a server such as and use that as your missing files host."

Blogger did not make this easy because I needed to make a new server, so I had to contact LinuxForce to help us one more time.

I think finally I am out of the woods on this transition! Now I can get back to my routine blogs on water treatment systems, news, innovation and technology.

Shut-Down of FTP Support on Blogger - Step 6

Well, I had to invoke step #6 "Have a good resource to call if this does not work!!". While the transition was smoother than I anticipated, I still needed a couple of redirect statements to solve some broken links and "Page Not Found" errors. The group helping me to get my Blogger account transitioned is LinuxForce. They verified what to do, gave me the simple steps required and made server and minor site adjustments. I am very satisfied!

Shut-Down of FTP Support on Blogger-Steps 3-5

Well, I think we might be okay. We need to do Step #5 with our web hosting support person later today. I could do it, but I'll let them. The next step will be to check links and history. Hopefully I will not need to employ Step #6 "Have a good resource to call if this does not work!!"

Shut-Down of FTP Support on Blogger

You may have seen a hiatus with my normally routine blog posts. I was a little preoccupied this past month. I was in a crisis about a imminent shutdown of FTP support on Blogger, the application we have been using to post our blogs.


We recently announced that our blog on water treatment is approaching its 4th year. Almost simultaneously, we were sent an email from the Blogger Product Manager announcing "a planned shut-down of FTP support on Blogger Buzz (the official Blogger blog), and wanted to make sure you saw the announcement". Not having the time, nor frankly the interest in following a Blogger blog on blogging support, we did not see it until the email on February 2, 2010. The clock was ticking so I needed to find out what to do and how implement a solution by March 26, 2010.

Main Challenges:

I am pretty savvy technically, but this one required some research. The main challenges were:

  • Using FTP to post our blog has been relatively painless.

  • Retaining the numerous links to and from Blogger to and other sites.

  • Losing our over 100 posts on our blog and/or having two locations were the blog resides

  • Losing our daily automatic backup of our blog during our normal, automatic website backup

  • Having to structurally change our website,

  • Needing to change settings at our web hosting company that they may or may not be able/willing to do

  • Losing our search rankings because of this substantive change in hosting from our server to a Blogger (Google) server

Some of the Research:

I read many articles on the web and in several recent books on possible blog posting software applications and strongly considered changing. A posting on Blogger Buzz seemed to indicate a smooth transition, but there were some server settings, redirects, and files required that I was unwilling/unable/scared to undertake on my own. Luckily my web hosting company has an excellent resource to walk me through the process.


Here was the process to make the transition:

  1. Set up in DNS

  2. Wait a day (This is the set I am at now)

  3. Follow instructions to "Update Your Blogger Settings" using as the "Custom Domain"

  4. Check to see if it works by navigating to

  5. Set up an .htaccess file to redirect traffic from to

  6. Have a good resource to call if this does not work!!

Since I am at step #2 going to start step #3, we'll see if this blows up and I lose 4 years of work!

Why did Blogger decide to do this?

Here is some additonal text from the announcment email. It sounds valid, but still a pain for us at Res-Kem:

"Last May, we discussed a number of challenges facing[1] Blogger users who relied on FTP to publish their blogs. FTP remains a significant drain on our ability to improve Blogger: only .5% of active blogs are published via FTP — yet the percentage of our engineering resources devoted to supporting FTP vastly exceeds that. On top of this, critical infrastructure that our FTP support relies on at Google will soon become unavailable, which would require that we completely rewrite the code that handles our FTP processing.

Three years ago we launched Custom Domains[2] to give users the simplicity of Blogger, the scalability of Google hosting, and the flexibility of hosting your blog at your own URL. Last year's post discussed the advantages of custom domains over FTP[3] and addressed a number of reasons users have continued to use FTP publishing. (If you're interested in reading more about Custom Domains, our Help Center has a good overview[4] of how to use them on your blog.) In evaluating the investment needed to continue supporting FTP, we have decided that we could not justify diverting further engineering resources away from building new features for all users."

Automatic DI Bank Switching and Data Acquisition Controller

Res-Kem has developed an integrated DI Bank Switching and Data Acquisition Automation Controller. The system monitors the inlet and outlet resistivity and the flow rate. At one of several alarm points, the system will send a text message to any number of email addresses and mobile devices. As part of a service agreement with Res-Kem/General Water, the system will warn Res-Kem/General Water personnel to prepare for a replacement of the soon to be exhausted bank of DI bottles.

Depending upon the system programming the bank will attempt to rinse to quality in several stages. If it does not succeed, the bank will switch to a standby bank and notify Res-Kem that the bank is exhausted fully and needs to be changed out.

The reason why Res-Kem developed this product is many people were having problems getting replacement parts and proprietary circuit boards for the excellent product called the Aquaswitch II a registered trademark of Myron L. Also, with reduced staffing at most of our customers, people do not have the time to monitor a stack light or resistivity monitor. As a result, the quality can be poorer than required potentially damaging down stream processes and products.

Tiny Particles Fight Giant Water Problem

Many of you may have heard of the chemicals that are in our drinking water including drugs, antibiotics, and other very small and difficult to remove chemicals. These can cause health effects at very low levels. Some disrupt the hormone systems of humans and wildlife, posing threats to fetal development and young children. Sources include birth control pills, prescription drugs, antibiotics, cosmetics and fragrances. People take the drugs and excrete them in urine.

In the online article "Pollutant-Fighting Particles Purify Water" in Lab News Daily by Laboratory Equipment, it briefly describes the continuing R&D project by two Charlton University professors to bring this technology to municipal and industrial waste water treatment plants. It will be interesting to see how they plan on removing the particles from the treated waste water in a cost-effective manner.
