Naturally Treating Water



Universal Environmental Technology (UET) and its partners around the world are constantly installing new systems and developing new solutions for ecological water treatment.

Here are some recent updates.


UET Fiesta!

UET-CCWS system on its way to Mexico to treat the closed water system of a plastics manufacturer, which also includes a UET 1×4 system with 4 sand filters. The unit was designed to oxidize and remove Fe from the water stream, and to provide mild disinfection for the water loop…all within a Chemical-Free solution.


Article 95

As part of UET’s ongoing effort to provide natural biocidal treatment for water systems, our electro-clorination process has been included in the European Union’s Article 95 list of approved active substances.



Genie in a bottle?

Not exactly, but UET’s system sized for a compact area in a food production plant was designed to contaminate (yes, contaminate) the water system so that the plant could run constant quality assurance tests on their filters for seven different lines. The project was complex due to the weight limitation of the floors, so the water had to be carefully distributed over the surface area.

Visit to Lebrija, Spain

UET’s founder – David Sherzer – just returned from a visit to our installation at a solar thermal plant in Lebrija, Spain, where UET’s technology has been keeping the water system clean from scale, corrosion and bio-contamination for the past 10 years – with zero chemical additives!

UET from on high

A UET installation from on high, treating the cooling towers at the largest copper mine in Africa.
From large to small…UET has the right solution to keep water in balance, thereby avoiding problems of scale, corrosion and bio-contamination.
Customer situation:
• Very Poor Water Quality
• Very poor cooling tower condition after extensive dosing
• Expensive chemical additive costs
• Continuous issues with scaling and corrosion (13.5 mpy with chemical treatment)
UET solutions:
• Huge amount of scale removed from the cooling water – 550Kg in every 2 months.
• Historical scale removed as well
• Corrosion rate reduced to 1.3 mpy
• Total water saving – 35,000 m3 per year
• Total Cost Saving – ~$216,000 per year


UET AFRICA hosted SASOL during a roadshow in South Africa to visit UET chemical free water treatment installations. These installations are reducing potable water consumption and eliminating the use of chemicals in various cooling system applications. SASOL is an international energy and chemical company working in 32 countries, which builds and operates world class facilities producing various high-value products, including liquid fuels and low-carbon electricity.

UET’s ninth patent

David Sherzer, UET’s founder and President, in receipt of a new U.S. patent for a method of solids removal in heat exchange systems, including a first water flow path from the heat exchanger to a cooling tower, then back to the heat exchanger.

La bella UET…in la bella Italia

UET’s European Account Manager was recently in Italy to review and service an installation serving a titanium manufacturer. The cooling water treatment has been in service for 2 years with good results, so treatment for an additional cooling system is currently being designed.

Cleaning the system with UET!!

In each UET system, supply water is passing through a series of reaction chambers which are configured to apply electrolysis to restore the supply water’s mineral balance to an optimum equilibrium. The chemical free water treatment produces biocides through the process of electro-chlorination, which eliminates bacteria and viruses in the water system. The electrolysis process also promotes oxidation and causes electrocoagulation and flocculation, which remove heavy metals from the water. Below is a comparison before (2017) and after (2018) implementing the UET water treatment on a large gland water service system. This supply water source is a combination of six different boreholes.

UET in the Field

In order to design its water treatment systems and ensure proper treatment post-installation, UET technicians conduct water analyses in the field, which allow any critical adjustments to be made so that your systems will always produce optimal results.
