|
| The WetSep System
is a patented product providing a turn-dey solution
for influent control. Designed and built in Hong
Kong , the WetSep is a versatile system and can
be applied in varoius types of industries.
WetSep has established itself as good maintenance
free system and has satisfied the needs of many
clients from International companies.

Advantages |
 |
A treatment
package of oil filtration, SS removal plus reduction
in levels of BOD and COD.
Nno power driven mechanical parts, all done by natural
gravity
Simple operation designed for unskilled labour
Compact and leaves a small footprint
Low capital and running cost
Low maintenance cost
Environmental friendly
Designed for easy transportation and setting up

|
| Structure |
| The
WetSep System consits of two main parts: Part 1 (ISR)
| Part 2 (UPC) |
| Part 1 Impinging
Stream Reactor (ISR) |
| The first
stage of the filtration process
Separating the influent into its element at this
Primary Treatment Unit
Effluent after ISR treatment removes 80-85% of
suspended solds, oil and grease from the influent
water
For all applications that required follculation,
coagulatoin and sedimentaion for the treatment
of water and wastewtaer, it would be a series
of mixing motors and pump motors. The consumption
of energy and shear of floc would be the disadvantages
of the conventional design.
The WetSep system in using Impinging Stream Reaction,
it requires no driven motor and makes the processes
ever more simple than before. By precise engineering
of the flow path, flow rate, pressure differential
and analysed data, the treatment can be completed
in one single vessel.
Thanks to the Computational Fluid Dynamics (CFD)
modelling technology, the performance of the WetSep
Filtration System has been opimized for every
application.
The engineering of the WetSep system does not
develop only within the design office, but also
in hand with the practical experiences, especially
the site condition is very much concerned.

| Part 2 Unviersal
Processing Chamber (UPC) |
| The Secondary
Treatment Unit
Treated water is clear and re-usable
Effluent following UPC treatment removes more
than 99.5% suspended solids and producing effluent
with SS<30mg/L
Universal Processing Chamber (UPC) is designed
to accommodate with different secordard treatment
requirements. As 80-85% of suspended solid has
been removed from effluent, the loading of the
secondary treatment in UPC will be greatly reduced.
A choice of corrugated plates, lamella plates
or membrance filters can be selected for varies
application like:
- Laundry
- Bean curd factory
- Food processing
- Dyeing industry |

| The WetSep has intrigued many people
in its simplicity and effectiveness. In April 2000,
the presentation of WetSep system drew a lot of
attentions from the expert and profession around
the world at the prestigious 8th World Filtration
Congress, which is held once every 4 years. More
than 10 units has been shipped to Taiwan , 5 units
installed for the most challenging project, Pinglin
Tunnel, rated at 500cuM/hr.
In Hong Kong the success of WetSep has been a
feature in many newspapers and magazines articles.
Its achievement shaped it to receive for its outstanding
design 1999 CMA Certificate of Merit in Machinery
and Equipment Design. |

| Case
Study |
The WetSep system is to provide treatment for
construction runoff in the course of building the
third longest tunnel in the world, liking Taipei
and Iland in Taiwan . This will happen 250m underground
where four WetSep80s will to be positioned inside
the tunnel for the treatment of the 350cuM/hr runoff
so clean effluent can be pumped back up to the ground
level.

The existing treatment plant at Ping Lin covers
an area of 3,000sq.M, cost HK$2,000,000, needs 24-hour
maintenance and encountered numerous mechanical
problems. A retrofit to the whole treatment plant
was the only viable solution which involved installing
technologies from the WetSep.
