Quartz sand filter industrial wastewater applications

Zhejiang jiaojiang some environmental protection building materials co. , LTD is a factory building materials equipment, the use of the ground after the coal produced a large number of coal powder, after flushing, a large amount of waste water produced by flocculation precipitation, water much cleaner, but haven't reached discharge standard can't reuse.

a phone call, we passed the field exploration, combined with their own equipment, a large tank will be second intermediate partition, formed a little point in the settling basin and a clear water reserviors, secondary sedimentation, after equipped with self-priming pump to quartz sand filter to filter, then treated water into the clear water reserviors, pollutants after backwashing after blockage, will intercept pollutants into the primary sedimentation tank under the precipitation, so as not to produce waste water discharge, and filtered water can be reused after processing, to achieve the result of recycling.

the original customer consider using bag filter, although the bag filter with high precision, large water yield, cost is relatively cheap quartz sand, but there is a weakness is to change the filter, this invisible increase the work and costs, so finally consider using quartz sand filter, or online backwashing and is renewable, no need to change the filter bag, introduces the running cost and manpower cost.

effluent water quality is good, no visible particulate matter, has reached the requirement of their recycling, saving a lot of water, for the company, 3 years can recycling equipment cost.
