water filtering process description

• 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 .
• 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 .
• 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.

process features and equipment function description

1,most outstanding features the filtering process

1.1 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.

1.2 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 can miss the limitations of using civil-work

1.3 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 higher than normalvertical flow reacting. Consequently ,rotational flow is very workable process prior to sedimentation .

1.4 Sedimentation of the system occupies larger area than conventional vertical flow sedimentation and thus displays a high efficiency than vertical flow sedimentation equipment.

1.5 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.

1.6 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.

Usage:

• Rivers, lacks, reservoirs and other surface water purification projects;
• Middle water reuse;
• Industrial waste water purification for mine water, coal washing water, baths, swimming pool, car wash, paper, printing and dyeing, electroplatin and other industries.
