Borehole water supply to a camp in the Kalahari.
Designed by Fluor, a camp for 1700 occupants, supplied by WESU and
commissioned last month, an ecofriendly water treatment with fast
return on investment. Somewhat different
from
the application opportunity at your operations but another vote of
confidence for the technology in Southern Africa.
A Botswana Kalahari camp was recently equipped with the WESU green, ecofriendly, water treatment technology. This technology is saving water and energy keeping the Solar Panels, showers heads, geysers and pipes, clean from scale, without having to use hazardous chemicals. Click here for more.

Barberton Mines’ Fairview
mine uses the Biox process which was developed by Gencor/Goldfields of
South Africa. The process entails the use of bacteria to br
eak down the
sulphide mineral matrix in the ore being treated, thus freeing the
occluded (closed) gold for subsequent cyanidation. The bio process is
exothermic and requires cooling to control the bacteria. Before the
installation of the WESU systems, the mine tried numerous technologies
to reduce the cost of cooling. During summertime at peak temperatures
the mine had to slow down the production as it lacked the cooling
capacity. Within eight months of the WESU systems being installed, the
mine experienced excess cooling capacity and had to cut pumping capacity
by more than 50% saving lots of energy.

When we started with the WESU system the old cooling coils was scaled up and the WESU system was busy removing the old scale. We had very low delta T of 90C (across the cooling coils), we currently running at 240C. (Now) we have a very high heat transfer rate through the cooling coils. In general we used to run two (45kw) pumps now we run one pump only. Click here for more.June 2009
In the USA
Presidential Green Chemistry Challenge annual award ceremony.
UET's technology has received recognition, after examining about 50 cooling systems in the USA. UET's technology is included in the protocol as one of the final candidates for the award. "It clearly demonstrates both technical excellence and a commitment to protecting human health and the environment…."
The EPA (Environment Protocol Agency) wrote about us that: "in contrast to the classical technologies to prevent scale formation using softeners, acids or chemicals to inhibit scale, UET's technology is providing controlled mechanism for sedimentation of troublesome scale in wide range of water systems. The UET solution is economical and environmental advantages and the potential of saving water is sustainable".
The USA Presidential Green Chemistry Challenge promotes pollution prevention through partnerships with the chemistry community. Through high level recognition and support, the Challenge promotes innovative developments in and uses of green chemistry for pollution prevention. EPA's Office of Pollution Prevention and Toxics (OPPT) is leading this voluntary partnership program with other EPA offices.

Yet
another delivery of our ecofriendly scale, corrosion and biolife
filtration system has been made, this time to Sappi Saiccor on the
Durban South Coast.
The most common scale we normally deal with is calcium carbonate in cooling towers, closed and open cooling systems, hot and cold natural water. This system was designed to filter out calcium sulphate in the process liquor. Calcium association with sulphate has a much stronger bond than the normal scale composed of calcium and carbonate, and as such it is much more difficult to remove from the water system. Click here

UET Systems in Plate Heat Exchanger applications.
In
the Makhteshim
Chemical Works process water is heated using Plate Heat Exchangers (PHE)
where water is on the one side of the plate and steam on the other. The
water used to deposit an extensive amount of scale, resulting in the factory
having to strip and clean the plates every three weeks. This cleaning is
very expensive, both in gasket and in labour cost, as the cleaning process
is labour intensive, and also in
downtime. Since the installation of the UET-SR-HW system the PHE has
been working without problems for long periods. Five weeks after the UET
installation the PHE was opened for inspection and found to be clean
like new. See picture.
WESU offers the UET technology which has been penetrating the African
market in a variety of applications since 2005.

First
for South Africa - Eco-friendly scrubber water treatment unit in
Newcastle
.
Last week the first WESU water treatment without chemicals landed at Johannesburg International Airport, from where it will be transported to Mpumalanga to help one of the world leaders in base metals production to clean up its environmental act, by cleaning its flue gases of harmful particles and clearing the air in the nearby town. After pouring in thousands of barrels of chemicals through the years and using potable water, the factory still had to stop the scrubber Rotary Disintegrator every second day and wash it with acid. Since the installation of WESU's new system, the Rotary Disintegrator has run for three weeks without having to stop for cleaning but, instead of potable water the system is now operating on slime dam seepage water, which inter alia contains cyanide. WESU "killed two birds in one system" on the one side it saved the scarce resource of potable water while on the other side it neutralise the cyanide and allows the slime dam water to be evaporated.
WESU specializes in environmentally friendly and economical water treatment systemsand supplies its proven and successful systems to all industries, mining, commercial, and residential. Its unique solution is also cheapest with ROI (Return Of Investment) stretched over only 12 months when taking into account the cost chemicals in use presently.

Eco-friendly Water Treatment First in Africa
The
first economical & ecologically friendly units of UET water
treatment without chemicals have been delivered to Botswana Mines.
Based on partial electrolysis technology, developed in Israel
fifteen years ago, these units disinfect the water and prevent scale and
corrosion by bringing the water into equilibrium without the correction of
pH or adding chemicals. 
Over
1 000 systems operate worldwide in a variety of applications from supply
water to cooling towers, industrial, mining and agricultural
applications.
For
the first time scale physically is removed from the water before
settling in the water system and corrosion is prevented without having
to correct the pH. Its disinfection properties are so excellent that
medical research centres are considering it for dialysis patient’s
treatment.
