lamella clarifier for water reuse equipment
The entire integrate system composes of a grid rotational flow reactor, fast inclined tube settler and gravity
valveless sand filter.
1. A Flocculation dosing device to make the flocculating agent go
through and mix into the raw water within
the mixing pipe. Then the dosed water enter the reacting tank of
the integrated high-effected filtering device .
There through multistage rotational flow , organics ,suspended
materials and colloid in the water combine
with flocculating agent resulting in larger flocs .
2. Those produced flocs together with water go into the
sedimentation tank and settle down to the bottom
with the action of gravity and inclined tube .
3. Then water is decanted from the sedimentation tank to the
filtering tank where smaller flocs are traped
over the surface of the filtering layer of quartz sand while clean
water go through the layer and go into the
clean water tank being ready for use.
1 .Short construction period with equipment manufacturing and civil
construction being performed
simultaneously. It can be even shortened by half time compared with
2 .Proactive and flexible system arrangement. Suppose production of
water is required to increase, you can
make it by only adding a set of equipment in a related size. This
misses the limitations of using civil-work .
3 . The system adopts commonly used rotational flow reacting which
features simple structure and provides high efficiency in producing
large flocs(alumen ustum). It can even achieve a level two times
normal vertical flow reacting. Consequently ,rotational flow is
very workable process prior to sedimentation .
4 . Sedimentation of the system occupies larger area than
conventional vertical flow sedimentation and thus displays a high
efficiency than vertical flow sedimentation equipment.
5 . Main equipment is made of steel with corrosion resistant and
includes no moving part. The life time of the
equipment can last up to 15 years.
6 . The integrated structure of the system requires 50% smaller
footprint than civil water filtering plant(Civil
gravity sedimentation tank + civil valveless siphon filter tank) .
Besides, it requires water for backwash at
amount 30% less than civil plant due to it’s higher efficiency in precipitation and no need for consumption of
water from clean water tank.
This integrated water treatment system fits to river water
treatment , clear wastewater treatment ,or treated effluent
treatment for life water or clear recycled water use , or test for
water supply work.
