7 Water Treatment Technologies used by Wacle
||Tech.-1 : Inline Mixing Technology|
An inline mixer consist of two different shape rotors in the pipe. During
influent water flow in the pipe, because each rotor turn opposit direction,
water automatically mixed with the lowest pressure loss possible.
Tech.-2 : Electro-Coagulation Technology
Chemical coagulatio to treat water has limitations especially heavy metal,
emulsified oil and suspended solid. But the electro-coagulation is very
effective to remove those materials. As a water containments (i.e. heavy
metal, suspended solids and emulsified oils) pass by the electro-pulse
plates energized by DC voltage, they accept a possitive and negative
charge causing the tiny particles to bond together like miniature magnets.
The clumps of particles either sink or float, depending on the characteristcs
of the waste stream.
Tech.-3 : Ozone Disinfecting Technology
“Chlorination”, the widely used method to disinfect water has been
proven to cause irritation, eye damage and cancer to some people.
But it is still effectively used today due to its low price. This system,
however, abandoned the chlorination as a method for disinfection of water
and came up with new technology called “Ozone disinfecting system” that
has 3,000 times more disinfecting power than chlorination.
Tech.-4 : 3 Rooms Clarification Tank
Automatic sensor in the machine applies chemical substances and
electricity to charge particles of water as pluses and minuses. These
particles are reacted, condensed and precipitated in part A.
Some particles that are still not precipitated are then processed through
part B as they go through Sheen Filter pack and get drained to part C.
The water that has been chemicalli and electrically treated is led into
part C where ozone disinfecting system sterilizes and removes small
from the water.
Tech.-5 : Auto Backwashing Disc Filtration
Water used in the shower and laundry especially contains large amount
of oils and lint which clog filter medium. Also, as time progresses,
the efficiency of the filter medium decreases very rapidly. Finally, they must
be changed to keep the recycled water clean. Disc filter system, however,
uses a new filter system which a felt liner place between two discs in order
to increase filtration effectively.
Tech.-6 : UF Membrane Filtration Technology
UF Membrane is a filter mediumthat is used in water purifier and is proven
to be most efficient in filtering out water. It also contains CIP features
which prolong its life span around 2-5 years.
The membrane’s pore sizes are 0.4-0.04 micrometer which further
provides more precise and safe filtration. These features can be controlled
by computerized program.
Tech.-7 : UF Membrane CIP Technology
UF Membrane is the best filter medium in the world, But just like any other
medium, it gets less effective in filtering out water as it wears out.
Due to its microscopic pore sizes and PVDF materials that make up the
membrane, filter medium gets clogged with debris.
But in order to cover these downsides, a back washing and C.I.P.
(Cleaning In Place) function are computer programmed to get rid of
any debris that can make the filter medium less effective than before and
can prolong its life span few more years.
