Greensand Price Increase

The manufacturers of Manganese Greensand have just notified us that the price of Greensand will be going up on June 1, 2007. The price of GreensandPlus (TM) will not.

Manganese Greensand is used to remove soluble iron, manganese and hydrogen sulfide from well water supplies. Greensand has been an industry standard for over 50 years. Manganese Greensand bulletin.

GreensandPlus is the second generation of greensand. GreensandPlus is more rugged than the original but has identical operating characteristics. GreensandPlus is a purple-black filter media used for removing soluble iron, manganese, hydrogen sulfide, arsenic, and radium from well water supplies. GreensandPlus bulletin.

GreensandPlus has the same effective size, uniformity coefficient, density, weight, capacity, backwash and pressure drop curve. Therefore, it can be used as an exact substitute for Manganese Greensand. In addition, GreensandPlus is much more resistant to attrition from high differential pressure, and works well on waters that are low in silica, dissolved solids and total hardness. It can also be used in water over 70 degrees F without any degradation.

Greensand is a mined product and as many users of Greensand know, it is occasionally in short supply. Unlike Manganese Greensand, GreensandPlus is not dependent on the mining of glauconite and this results in reduced production time. Greensand Plus is readily available for purchase.

All Manganese Greensand shipped after June 1st will be subject to the new prices. Contact Res-Kem for availability and current and future pricing.

Res-Kem manufactures systems using greensand and GreensandPlus to remove soluble iron, manganese and hydrogen sulfide from well water supplies for municipal, commercial, and industrial applications.

Homespring Water Purifier to be Stocked By Res-Kem

The Homespring Water Purifier will be stocked by Res-Kem Corp.

Previously, the Homespring Water Purifier was marketed for a number of years through a master distributor program direct from the inventor of the system, Zenon. Now, GE Water will be distributing these systems through qualified OEM's. Res-Kem Corp is one of the qualified OEM's and will be stocking these units.

Homespring Certifications:
The Homespring Water Purifier is system tested and certified by NSF against NSF/ANSI 42 & 53 for:
- Cyst Reduction
- Turbidity Reduction
- Particulate Reduction Class 1
- Chlorine, Taste and Odor Reduction

General Specifications of the Homespring Water Purifier:
This innovative system uses ultrafiltration technology to provide the homeowner protection against viruses, bacteria and Giardia cyst. The maximum continuous flow rate is 4.5 gpm with peak up to 11 gpm. Units can be coupled for greater flows.

Homespring Features:
Whole House Treatment
Optional Activated Carbon Prefilter
ZeeWeed(R) Membranes
Flush Out Drain
Self-Cleaning, automatic backwash

Homespring Dealer Certification:
Dealers will need to be tested and certified by GE/Zenon prior to taking delivery of these systems. An on-line test is available for easy access to the certification process. Once certified, dealers will need to make a one-time purchase of an integrity test kit to ensure proper application of Homespring.

Homespring Pretreatment:
While we are just learning about this innovative product, we do know that this unit does not reduce TDS. Also, excessive hardness may foul the membrane. Although the membrane can be treated with citric acid, a softener is recommended as pretreatment. Soluble iron will pass through the membrane so staining is probable.

Homespring Rules:
In order to make the "purifier" claim certain rules exist.
1. OEM's and dealers cannot tell customers that the Homespring is certified for surface or groundwater purification. Most states require approval of each install in advance for these applications - on a site-by-site basis. OEM's and dealers cannot bypass these state regulations. When an installation requiring state regulatory approval is made, the Homespring technical team will need to be contacted.
2. Pricing cannot be posted to the web.
3. Unauthorized individuals cannot install the Homespring. This is important. The technicians installing Homespring must be tested and certified individually!
4. Homespring cannot be installed without an integrity test.

Assembly Facility Expanded by 6000 sqft

In order to meet our demand for new industrial, residential, and commercial water systems, Res-Kem Corp. recently completed the move to our new, 6,000 square foot, expanded assembly facility in Aston, Pennsylvania.

As part of this effort, our Production Manager, is instituting the Kan Ban system to streamline inventory, improve order accuracy, and decrease production times. Also, we are completing an expansion of our Water Supplies Distribution Warehouse to provide better service for and rapid deliveries of the ion exchange resins, filter media, Fleck valves, Aquamatic valves, Autotrol valves, Stenner pumps, etc. you need.

Please contact us for a plant tour of our Assembly, Distribution Warehouse, and Service DI Resin Regeneration Facilities. We are just south of the Philadelphia International Airport.

Condensate Polisher with All Stainless Steel Construction

Last week, Res-Kem shipped a condensate polisher designed to treat an 80 gpm flow rate with a 390,000 grain capacity. The condensate polisher had an all stainless steel construction including an ASME code stainless steel pressure vessel, stainless steel internals, stainless steel Aquamatic valves and face piping. Not shown is the brine tank used to regenerate the high strength cation resin.

Condensate polishers can save a considerable amount of energy by reclaiming waste heat that is in the condensate return from steam boilers, rather than having a large "blowdown" to drain. Treating the condensate return, and keeping the temperature high, usually around 120F, with a condensate polisher, the blowdown rate to drain can be dramtically reduced. Recent calculations show an ROI in as little as 6 months!

Ion Exchange Resin Equivalency Chart

There are many different ion exchange resin manufacturers including Purolite, Dow, Sybron/Bayer, Thermax, Rohm and Haas and ResinTech. We are often asked to provide a resin that is the closest equivalent to the ion exchange resin they have or need to purchase. This is a list we use internally of the most common ion exchange resins and not an exhaustive list of all ion exchange resin equivalencies. Res-Kem does not guarantee the accuracy of this listing. It is, to the best of our knowledge, correct. Please call us to confirm a selection.

Water Quality Test Kits and EPA Regulations

While researching home water quality test kits and the EPA regulations, I found an excellent PDF list of EPA National Drinking Water Regulations on the US EPA website. This list of regulations is color-coded to clearly show Disinfectant, Inorganic Chemical, Organic Chemical, Disinfection Byproduct, Microorganism, and Radionuclide drinking water contaminants

Also, on this list, the EPA groups the regulations in two classifications, National Primary Drinking Water Regulations, NPDWRs or primary standards, and National Secondary Drinking Water Regulations, NSDWRs or secondary standards.

The Primary Standards are legally enforceable standards that apply to public water systems. Primary standards protect public health by limiting the levels of contaminants in drinking water.

The Secondary Standards are non-enforceable guidelines regulating contaminants that may cause cosmetic effects, like skin or tooth discoloration, or aesthetic effects, like taste, odor, or color, in drinking water. EPA recommends these secondary standards to water systems, but does not require systems to comply. However, states may choose to adopt them as enforceable standards.

Water Softener Standard Product Line Revamped

The Res-Kem "FT", water softener product line has been revamped yielding a complete line of standard products that can treat flow rates between 8 and 120 gpm using single units, continuously up to 140 gpm using dual units and with peaks rates up to 240 gpm. The standard capacity range is 60,000 to 600,000 grains between regenerations for single units. The standard capacity range is 120,000 to 1,200,000 grains between regenerations for dual units. and unlimited for multiple units. By standardizing the product line, most systems are available for immediate pricing and shipment from inventory**.

A complete documentation package has been developed including a new brochure
, engineering outline drawing, equipment specification sheets, and suggested enduser price lists.
The FT-Series dual tank softeners are designed based around the Pentair Fleck 2750, Fleck 2850, and Fleck 2900 valves. The 2750, 2850, and 2900 Series feature an all brass control valve. These rugged control valves provide a low maintenance, high flow rate, and quality system able to meet the most demanding needs.

With the optional Fleck 3200NT electronics and flow meters dual units can operate in parallel, alternating, and series operation. These automated units can be designed to provide continuous soft water 24 hours per day. Perfect for boiler treatment applications.

Boiler Feed Water Flow Rate Requirements Chart

Question:
We received a request for proposal today for "a water treatment system to treat the water going into my dual 194 HP steam boilers".

Start of an Answer:
The first thing we need to do is estimate the amount of water that will be used. The question is how?

After you work in any industry for many years, everyone collects their favorite charts, rules of thumb, "crib sheets", etc. They come out of drawers, filing cabinets, binders, etc. as a result of the question and follows the statement "Don't you have this chart??"

This morning, I was given one of these charts from one our "learned gentlemen" (as he wants to be referred to as) and felt it would be great to share this boiler feed water flow rate requirements chart. I wish we knew the source of this data, but as is often the case, it was copied too many years ago for anyone to remember. This chart relates boiler horse power to the flow rate in gallons per minute and pounds per hour. In this case, we need a demineralizer or softener rated for a maximum flow rate of 28 gpm. It will be less depending upon how much condensate is returned.

The next part of this question is what water quality is needed for the application. The steam pressure and steam boiler manufacturer will help determine what the water quality needs to be. Stay tuned.

Whole House RO System for Brackish/Salt Water

Here are some pictures of an interesting project our team out of our Jacksonville, Florida warehouse and assembly facility recently configured for a well driller customer. The system was designed to treat brackish/salt water from an ocean front property. As you can see, given the complexity of the water problem and limited space, the equipment was squeezed into a small space.






System Description:
This house is right on the ocean, pulling salt water in from a well. The house is very close to Marineland, Florida (The home of Flipper!) .


As expected, the well has a high Total Dissolved Solids, TDS, value. Also, the water had a "rotten egg", Hydrogen Sulfide, H2S, smell.

The equipment is as follows:

Well pump and tank

Hydrogen Peroxide injection system with Stenner PCM 5 controller and Hayes meter to correct the Hydrogen Sulfide, H2S, in the incoming brine/salt water

Whole house carbon filter with backwash system

Twin tank Fleck 9100 softener system for continuous treated water even during regeneration

10 micron prefilter

Whole house RO system rated for 1800 GPD

500 gallon atmospheric storage with level switches for pump protection

Repressurization pump and tank for house feed water

Fleck 5600 backwash polishing filter for pH and taste control

Hydrosafe 12 gpm UV Light with stainless steel housing for bacteria control activated with flow switch.
