Condensate Polisher Shipped to Michigan

A condensate polisher for a district heating plant in Michigan was shipped last week. 


Dual Skid-Mounted Condensate Polisher for District Heating Plant in Michigan

Customer:	Utility District Heating
Water treatment application:	Condensate Polisher to scavenge trace hardness and iron
Expected savings:	Loss prevention keeping heat transfer surfaces clean and reliable for years of trouble free operation
System configuration:	Dual Parallel. On-Board Controller has a relay to indicate start and stop of regeneration process on each polisher vessel. The plants in house DCS system then ramps down the flow rate to each condensate polisher based upon regeneration schedule and times
Materials of construction:	Pressure vessels are 304 stainless steel with 125 psig ASME code stamped All face piping is welded and flanged Schedule 40 SS 304ss welded to B31.1 standards
Valve and actuators type	All automated valves are Bray valve Lug style for 150 ANSI flanges. Actuators are Bray pneumatic.
Control philosophy:	The utility didn’t want to reinvent a control scheme within their DCS, so the off the shelf controllers are being used locally to control both units. System parameters like individual tank flow and regeneration status are outputted to the plants DCS system.

3D Printed Model of Rental Condensate Polisher

To speed up installation of our rental condensate polisher, we will provide a 3D CAD file as part of the documentation.  This is will insure the condensate polisher starts delivering energy, chemical and water savings as quickly as possible.  As a result of having the 3 D CAD model, we had some laser sintered models of the units printed.  The size of the models is approximately 3"D X 8"W X 5"H.

Front and Side View of Triple Rental Condensate Polishing System

The cost of a 3D model depends upon the time in the machine, and the amount of polymer used to make the model,  To save polymer, you will notice we made the pressure vessels with a checkerboard pattern allowing unreacted plastic powder out of the model.

Pentair Fleck Valve Training - Day 1

Res-Kem was able to bring two of the top experts directly from the Pentair factory, Matt Walloch-CWS-V and Doug Haring-CWS-VI, to present two days of intensive training on commercial and residential valves.  25 people attended Day 1.

Doug Haring-CWS-VI of Pentair presenting information on the problems with high or low pH in water

The first half of Day 1 covered an introduction to water softeners and filters using Fleck's multiport valves. Presented were insider tips on water treatment as it relates to the operation of water softeners and filters. The remaining time was a valve clinic covering the 5600, 5800, 2510, and 7000. Covered were electronic programming and the idiosyncrasies related to the various electronic packages.

 

Each WQA member who attended will receive WQA seat time credit.

 

Demineralizer Regeneration Frequency Determination

Routinely, I am asked how long will one of our cation-anion two bed demineralizers operate before it has to regenerate. To determine this, we need to know the flow rate and the inlet water quality.  The flow is generally known, but the water quality generally is not early in a water treatment project.  The easiest way is to use conductivity as a rough approximation of water quality for budget purposes only.  Before a system is purchased, a complete water analysis is required to verify with one of the ion exchange resin sizing programs to purchase the correctly sized demineralizer.

Here are a series of graphs I sent to the prospect to help get a budget determined.  The graphs include run times for a DT36072, DT54072 and a DT60072 dual bed demineralizers from Res-Kem.

Selecting the Perfect Filter Cartridge

Being a distributor of water treatment supplies, we are asked to provide filter cartridges. Most of the time, these requests will consist of: "Hey, I need a 5 micron 20" long cartridge." Sounds simple enough; however, there's more to a filter cartridge than the just those two particular pieces of information. Below is an overview of what is needed to select an ideal cartridge for your application.

Filter Cartridge End Configurations

What is the application?
Knowing the application can provide an idea if an absolute or nominal cartridge is required. An Absolute Cartridge by definition retains 99.9% of the particles within that micron rating. These types of cartridges are typically used for critical applications such as process water in the Pharmaceutical Industry. In most cases, we deal with nominal rated cartridges in which the cartridge retains a majority of the particles of the micron rating that pass through it. For the sake of the above request, let’s say the customer tells us he needs a cartridge filter as pretreatment before a carbon filter. From our experience with this application, we now know that a nominal rated cartridge will work fine, we just need to a little more information,

Do you have a part number of your existing cartridge?
Obviously, if a customer can provide a brand and a part number, this makes the process a smooth transition. There are a lot of different cartridge manufacturers, such as, Pall, Shelco, Watts, Millipore, etc. Usually, they offer very similar products that can be used within an application. If it is okay with a customer to offer a substitute, we will try to find a cartridge we carry that will work for them.  In this case, they do not have a part number, so we need to get a little more information.

Cartridge Dimensions:
Since we already know the length of the cartridge, 20 inches, the next bit of information we need to determine is the diameter of the cartridge. From our research, the most common diameter we have come across is a 2-3/4" cartridge. Other diameters we have seen are 2-1/2" and sometimes 2" diameter cartridges. Another popular diameter is the 4-1/2" size, most commonly referred to as, "The Big Blue Cartridge", because of the large blue colored housing these cartridges fit into. If the customer is not sure, we ask that they obtain diameter measurement from a micrometer or caliper or even put a ruler across the cartridge to get an idea. A measurement of the housing will also help us select the right diameter cartridge. For this application, 2-3/4" diameter is what is needed.

Materials of Construction:
Next, we inquire about the material of the cartridge and the type. Cartridges can be made of different materials, such as, Polypropylene, Polyethersulfone PES, Cotton, Rayon, etc. These materials can made into different types of cartridges like melt blown, string-wound, and pleated. Because we focus primarily on potable water treatment, we most commonly sell FDA grade Polypropylene, or Cotton. Cartridge manufactuters also provide information on common applications their cartridges can be used. For our case of a pretreatment cartridge before a carbon filter, a melt blown or string wound cartridge will work fine in this application with FDA Polypropylene or Cotton.

End Configuration/Gasket Material:
Cartridges can have different types of ends, from a double open ended, single open end - 226 O-ring with Flat end, single open end 222 O-ring; Fin(Spear), etc. And, different types of gasket material from Buna N, Silicone, Teflon, etc.

If a customer is not sure, we can either send this document along to them, or they can easily send us a photo of what they have which will allow us to determine the end configuration. The gasket material becomes important when you are dealing with something other than potable water. Typically, there will not be a gasket, or it will be Buna N or Silicone. In the case of this application, we determined this cartridge is a double open ended cartridge with no gasket.

To summarize, we need to quote the customer a 5 micron, 2-3/4" round x 20" long, melt blown, polypropylene, double open ended, nominal cartridge to pretreat water before a carbon filter. For us, it now becomes a question of pricing, availability, and packaging from our different suppliers. We can then present the customer with some options for them to determine.

OSHA Required Deadline You May Not Know About-December 1, 2013

Do you use chemicals or produce chemicals in your facility?  You may not be aware on December 1, 2013, OSHA, Occupational Safety and Health Administration, REQUIRES you to train all of your employees on the new chemical labeling elements and safety data sheet format, in addition to the current training requirements.


New Pictograms for Hazard Communication

If you have MSDS's at your facility, you will start seeing changes, with the above pictograms, from now on and should receive new SDS (Safety Data Sheets) before June 1, 2105. 

General Overview:
According to the Hazard Communication Standard Final Rule Fact Sheet:
"New changes to the Occupational Safety and Health Administration's (OSHA) Hazard Communication Standard are bringing the United States into alignment with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), further improving safety and health protections for America's workers. Building on the success of OSHA's current Hazard Communication Standard, the GHS is expected to prevent injuries and illnesses, save lives and improve trade conditions for chemical manufacturers. The Hazard Communication Standard in 1983 gave the workers the ‘right to know,' but the new Globally Harmonized System gives workers the ‘right to understand.'"

Dates You Need to Know:

Major Changes:

• Hazard classification: Chemical manufacturers and importers are required to determine the hazards of the chemicals they produce or import. Hazard classification under the new, updated standard provides specific criteria to address health and physical hazards as well as classification of chemical mixtures.
• Labels: Chemical manufacturers and importers must provide a label that includes a signal word, pictogram, hazard statement, and precautionary statement for each hazard class and category.
• Safety Data Sheets: The new format requires 16 specific sections, ensuring consistency in presentation of important protection information.

What are the Benefits?

• Enhance worker comprehension of hazards, especially for low and limited-literacy workers, reduce confusion in the workplace, facilitate safety training, and result in safer handling and use of chemicals;
• Provide workers quicker and more efficient access to information on the safety data sheets;
• Result in cost savings to American businesses of more than $475 million in productivity improvements, fewer safety data sheet and label updates and simpler new hazard communication training; and
• Reduce trade barriers by harmonizing with systems around the world.
