Bacteria, Mold Spores and Viruses in Your Product

Waterborne Bacteria, Mold Spores and Viruses all threaten quality of your product. We are helping an increasing numbers of facilities that have recognized the inherent risk of microbiological contamination of the water used to make their product.
This occurs because water provides an effective medium for growth and transmission of bacteria, mold spores and viruses particularly where water stagnates in your plant.

Note: It’s not just pharmaceutical plants that are contacting us these days to help implement a microbiological control program!

If your facility uses water for/in blending, consumer products, personal care products, microelectronics manufacture, beverage production, packaging, etc., you should be increasing your awareness and building capability to monitor and control microbiological species of all types.
What can we do?
We can help you develop a microbiological control program that protects your plant and products! There are many methods of minimizing your risk in this area but all include a few different components:
  • Prefiltration before your DI Process tanks
  • A recirculation loop to keep the water moving and fresh
  • A UV system which has very high effectiveness in removing protozoa, bacteria and viruses, and many options to fit your needs and budget
  • A post filter to remove many of the matter left after UV destruction
  • A PM (Preventative Maintenance) protocol that includes regular monitoring of multiple forms of bacteria, molds, and water borne contaminants.
  • A PM schedule for maintenance and sanitization of your system including all piping and drop legs
For Additional Information:

Industrial Water Softener Installed-Before and After Photos

A Delaware cosmetic derivatives manufacturer installed a dual tank industrial water softener to replace their 25 year old zeolite softeners. The transformation of the building and installation of our water softeners by the mechanical contractor was exceptional!
BEFORE - Existing Softeners During Tearout

AFTER - New Dual Res-Kem Softeners Installed After Building Refurbishment

Water treatment application:
Replacing 25 year old zeolite softeners
Savings and/or ROI the customer wants to achieve
Clean up the zeolite operations and the room where they reside. Automate the regeneration process and the monitoring of the water softeners
Operating conditions:
60-120 gpm boiler make-up
System configuration:
Singe or Dual Parallel operation PLC controlled
Materials of construction:
Since the source water being well water and the room ambient air temperature can be very hot > 95 F, condensation that can form on the tanks, therefore fiberglass tanks were used.
Schedule 80 CPVC was used to provide more strength to the system piping
Valves were Bray butterfly valves all stainless wetted parts
Threaded or welded:
Glued, Schedule 80 CPVC and flanged unit piping
Type of valves and actuators:

Increase Commercial Water Softener Efficiency With a Twenty Dollar Part

On a recent sales call to a local dialysis clinic, the biomedical technician complained about a distinct loss of capacity in his water softener. Asking the typical diagnostic questions, such as resin age, brine system inspection, the Bio Med told me they recently upgraded their Reverse Osmosis machine and they are using considerably more water. End of story correct; more water used, more regenerations required? Well No. We ran the numbers and still concluded he was regenerating the softener too often. Something else was wrong.
Tank X-RAY
I had one last trick up my sleeve. “The Tank X-Ray”. Yes, folks, you can X-Ray a softener tank with a 500 watt halogen work light as sold in many home improvement stores. The X-Ray process is easy; you darken the room, turn on the light, and press it against the upper 1/2 of the tank. Now, this only works with a natural color fiberglass mineral tank. The bright light will not penetrate a painted tank. The light will let you gaze at the insides of the tank. Everything will appear as shadows.
What we discovered here was the resin beads were all bunched up to one side of the tank. NOT GOOD. The resin should appear as an even, level, dark line across the whole diameter of the tank. AH HA! This tank was suffering from a little known chronic problem called “Diffusion Exclusion”. Someone forgot to include the Inlet Diffuser/Disperser. The inlet diffuser is an option offered with the new control valve that regulates the resin regeneration process. This small critical part is often discarded as unidentifiable.

Don't Throw Away the Plastic Inlet Diffuser/Disperser on Left!
Penatir Fleck 19608-15 Inlet Diffuser/Disperser Installed on Pentair Fleck 2850 Valve
The inlet diffuser is attached to the underside of the control valve during tank assembly. Its main purpose it to diffuse the path of the water flowing into the resin bed during the DOWN FLOW service cycle. The diffuser forces the water evenly outside, then down. Without the diffuser, the water path is straight down. The result is a drilling effect. The drilling gets worse as the flow increases.
Two bad things happen:
  1. The resin is usually blasted and gets bunched up.
  2. You lose efficiency at high flow because the water isn't flowing evenly through the resin bed, it's drilling past it. 

In Conclusion:
Avoid Tank Turmoil. X-Ray your tank. It’s actually fun to do. Even more fun is to start your softener into a regeneration cycle and watch your resin expand upward during backwash and float around like lava, then see it settle down during the rinse cycles.

How Biofilms Form on Surfaces By Swimming Cells

In a very interesting article by Medical Design Technology titled "Findings Suggest How Swimming Cells Form Biofilms on Surfaces", scientists at Purdue University’s School of Mechanical Engineering modeled how biofilms actually draw swimming bacteria to the film and how bacterial colonies to thrive on surfaces.  It is interesting how the same mechanism which causes fouling of implantable medical devices, fouls our UPW distribution systems, industrial pipes and boat propellers. 

This model confirms what we see in the field that once a biofilm takes hold, the problem seems to accelerate in severity. This is why Res-Kem recommends routine sanitizations of water treatment distribution systems to remove biofilms.

Iron, Manganese, Sulfur-The Troublesome Trio

Commonly referred to as the Troublesome Trio, Iron, Manganese and Sulfur, although not a real health concern, these dastardly elements will reap havoc on a plumbing system.  As little as 0.05ppm of Manganese will cause staining of plumbing fixtures.  Only 0.5 ppm of iron will cause staining.  And Sulfur?  P.U.!  Need I say more?

To battle the Trio, professionals have traditionally used Ion Exchange water softeners and Oxidation/Reduction media.  Ion Exchange only works on dissolved iron and manganese and is prone to fouling and won't treat sulfur.  So my experience is to apply oxidation media that has been treated with a coating of Manganese Dioxide.  These media are popular in the industry and are sold under the trade names of Birm, MTM,  Pyrolox, Filox, and Greensand Plus.  All these media have different percentages of manganese dioxide coatings.  The amount of coating determines their capacity.  The key to success lies with this capacity.

Manganese Dioxide acts as a catalyst that utilize oxidizers fed into the water stream ahead of the media bed to perpetuate the oxidation and reduction process.  Pre-feeding oxidizers is commonly called "regeneration". Please note, in all my years of experience, your success with these media depends heavily on choosing the correct oxidizer.  It is a VERY rare application where you don't need to pre-feed an oxidizer.   The most popular oxidizers are potassium permanganate (very messy because it stains everything purple) , Sodium hypochlorite (bleach), Air, or 7% Hydrogen Peroxide.  The most popular is bleach.  Be careful to follow the manufacturers guidelines for feeding oxidants.  To much will strip off the manganese dioxide coating.

Now The Exciting News:
Prince Minerals has developed a new Media called Pyrolox Advantage (PA).  PA is manufactured with a proprietary process that gives it a high capacity, yet maintains a lighter-than-most density so backwash rates are greatly reduced over traditional Manganese Dioxide products.  Thus the "Advantage" part.  Additionally, its lighter density will make it a direct replacement for another popular media called Greensand Plus.  An even bigger advantage, is that Pyrolox Advantage has nearly 3X the oxidation capacity.  Its increased capacity will lengthen run time between back washing saving significant amounts of water.  To conclude, if you are currently filtering with greensand plus or are battling any of the Troublesome Trio, please try Pyrolox Advantage.  It's priced right to win the fight!

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.

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.
