Improving the Kent Water Filtration System

Did I just grab a tiger by the tail or what? How pompous is little ol’ me to dare redesigning the technology of a prominent water technology company?  The answer of course is that I am not pompous, I am after all, Tommy V, the world’s greatest, most dynamic, knowledgeable, handsome, and I must add humble, water expert. I am the World’s Water Doctor!

With that out of the way, let’s talk about the Kent™.  I want to first say that I am very impressed with the Kent™ products. They are very well made both from a mechanical perspective and also from a design standpoint. Unlike most home water purification technology, these products look like modern technology. The enclosures are downright beautiful and they can be installed anywhere and not look like an eyesore. They actually look similar to the many professional laboratory/research grade units that you find in hospitals and research centers all around the world. Very, very well done.

In addition, Kent™ uses top notch components in all of their products. The engineering and installation is impeccable. Make no mistake, these are the finest home water filtration products money can buy. The company is based in India and I really do not know what their US representation and availability is. Suffice to say, they are an impressive technology company offering a wide array of well-designed products.

One of the impressive innovations in the Kent system is an on-board computer that analyzes the total dissolved solids in your feed water and then diverts some of the RO water directly to storage while sending the rest through an ultra-filter/ultraviolet light path. The two waters are then blended together in the storage tank; at the point of drinking/dispensing. By doing this the Kent system keeps some of the minerals in the water. Many consumers find the taste of RO water to be flat. Bottled water companies such as Aquafina™ and Dasani™ actually put minerals back into RO water before bottling it to provide better taste. 

Kent™ does not add new minerals to the water, but instead uses the TDS computer to allow some of the already existing ones to pass, while removing bacteria and other harmful chemicals from the RO bypass stream. The one caveat to remember however, is that if there are undesirable trace contaminants in your raw water, by bypassing the RO, the Kent™ unit does allow some of those contaminants, in conjunctions with the good minerals to pass into your final water. RO removes 99% or more of all contaminants. The UF filter however does not remove dissolved solids, but is a great filter against bacteria, viruses and other organisms.

My main design concern with the Kent, as it is with every home water filtration product I have encountered, is the static storage of de-chlorinated water. Regardless of who designs a system and regardless of how good the components and build are, water without chlorine in, when allowed to stand static will eventually become contaminated and grow bacteria.

Kent™ Water Process Improved

  • UF should always follow UV because once bacteria are inactivated by UV they become fragile and can split into harmful pyrogenic particles under the pressure and flow of dispensing and moving the water.
  • Water from a storage tank should always be recirculated through UV and a post filter, in this case UF to prevent bacteria from regrowing.

I look forward to the day when all designers of home purification technology will recognize the flaw in the design of allowing de-chlorinated water to stand stagnant!
