Product Description
sand filter
1,Working principle
The activated carbon filter is adopt granular active carbon further to remove
the residual chlorine, organic matter and impurity in suspended solids in effluent water, supply favorable condition for following up reverse osmosis treatment system.
It mainly adopt high carbon content, molecular weight, large specific surface area activated carbon organic flocculating body to make physical adsorb the impurity in water, to reach water quality requirements, when water flow pass the activated carbon water opening, each kind suspended solids,organism etc was adsorbed in activated carbon opening in the action of Van der Waals force; meanwhile,
the chloride (hypochlorous acid) adsorb on activated carbon surface on the carbon surface make chemical reaction, be restored into chloride ion, thus effective remove chlorine, to guarantee the effluent residual chlorine volume less 0.1ppm, to meet RO membrane operation condition. With time evolve , the intercept objects between active carbon pores and particles gradually increase, to make the filter before and after pressure increase, till invalid. In general case, according to filter before after pressure, adopt reverse water flow backwash filtering media. To make most part of intercept objects which adsorb in activated carbon porting peel off and take off by water flow,restore adsorb function;when activated carbon reach saturate, adsorb volume thoroughly invalid, it should make replacement of activated carbon or regeneration activated carbon, to meet the project requirements.
When due to activated carbon filter intercept excess mechanical impurity and influence its normal working condition, it can make washing by back washing manner. Use reverse direction inflow, to make the sand filtering layer loose, to make the intercept matter which adsorb in filtering media surface peel off and take away by backwashing water, be favor of exclude the Sediment, suspended solids in filtering layer, and prevent filtering media harden, to make it fully restore intercept dirty,remove chlorine ability, thus to reach washing purpose.bachwashing to control the backwashing period by set inlet outlet pressure difference data, usually, it is 3 -4 days,the condition should be depending on raw water turbidity.
Activated carbon filter adopt stainless steel operating valve group,filter start,front washing,backwashing,shut down etc procedure all by manual control.
When activated carbon filter operating till inlet outlet pressure is 0.05~0.07MPa,
It should make backwashing. Activated carbon replace period is 1 year and a half year.
2,Feature
Filter body is with up and down ellipse end socket cylinder structure, filer material is Q235-A or SS304, lined with vulcanized rubber anti-corrosion, inner set water distributor in water inlet, below set water collecting device, it filling 1200mm activated carbon and 200mm quartz sand in water collecting device. Whole set filter tank body external device equip each control valve and flow meter,pressure gauge.
The filling activated carbon is nut shell carbon, it has the advantage of light proportion,Large porosity, high resistance to wear, big adsorption capacity etc.
Filling height as following:
Activated carbon 0.6-1.2mm 900mm
Quartz sand 0.6-1.2mm 100mm
