I Overview

The entire integrated Water Filtration equipment composes of two main parts, the grid rotational flow reactor, fast inclined tube settler and gravity valveless 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 higheffected 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. The water clarifying process finish.

II Features

1 .Short construction period with equipment manufacturing and civil construction being performed

simultaneously. It can be even shortened by half time compared with civil-work project.

2 .Proactive and flexible system design. Suppose production of water is demanded to increase, you can make it by only adding a set of equipment in proper specification. This miss 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. It achieves a level two times higher than using normal vertical flow

reacting. Consequently,rotational flow is pretty workable process prior to sedimentation .

4 . Sedimentation of the system occupies larger area than convent

ional vertical flow sedimentation and thus displays a higher efficiency than vertical flow sedimentation equipment.

5 . Main equipment is made of steel with corrosion resistant and involves no moving parts. 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.
