Water Tanks activated carbon wastewater treatment

Description:

Activated carbon filter design parameters should be based on water quality, processing requirements and types of activated carbon, a reference power plant operating experience similar or determined by tests and shall comply with the following principles:
  A, should choose a good mechanical strength, absorption speed, high adsorption capacity of the activated carbon
  B, activated carbon filters on the hydrogen ion exchanger after filtration rate can be raised.

Features of the water filter

Simple sand filter device structure, operation, backwash more convenient, its operations mainly through regulating four valves, change the water direction changes.
Quartz sand filling should be noted: quartz sand interception layer specification 0.5-1.0mm, a height of 700mm or more, the support layer has two layers, namely, 1-2mm in height packed 150-200mm ,2-3mm in height packed 150 -200mm. Untreated water, its interception capabilities 0.5-1.0Kg/m3, after water lime treatment, the interception capacity of 1.5-2.0 Kg/m3, coagulation treatment for the treated water, the interception capacity of 2.5-3.0 Kg/m3.
