Continuous sand filter is widely used in many fields, especially for drinking water, industrial process water, sewage and industrial waste water purification. It is a kind of continuous filter, combined flocculent, settling, filtering together. For tertiary filtration of reclaimed water, the gravity sand filter offers advanced treatment: Efficiently remove suspended and colloidal solid, oil, iron and manganese oxide, and kill the bacterial, algae, virus in water.
Trap organics,suspended solid,colloidal solid,microorganisms in water.
Remove nitrogen and phosphorus
Reduce COD(Chemical Oxygen Demand) in water
High Efficiency: Work online 24 hours,no need stop to backwash
Low operating cost:No need the high flow and high lift backwash pump,and it can be programmed to control
intermittent wash sand control mode, greatly reducing operating costs.
Low maintenance cost: without any moving parts,
low failure rate during operation and low maintenance costs.
Low one-time investment: no coagulation tank, clarify pool and other facilities, filters, high utilization
Lower requirements on inlet water quality: long-time bear SS: 150mg / L.
Can withstand short-time SS:250mg / L.
Low Head Loss: Due to the single-stage filter,we clean the sand timely, head loss will be reduced to 0.5m
Efficient Filtration, Stable outlet water quality: Due to the timely clean filter can ensure stable and efficient filtration,
no water quality cyclical fluctuations.
Easy for expansion: Unit operating mode can be adjusted according to changes in water quality and quantity of filters, easy to renovate and expansion of existing facilities.
Surface load in the unit time per filter surface impurities trapped, units:mgSS / m2h.
Recommended active sand filter surface load values are as follows:
Continuous sand filter can withstand a higher load than the value of the surface in a short time.
Filtering area can be determined by the largest surface area of the filter load
and raw water quality and quantity.
For security, the actual selection should be slightly larger than the calculated value of the filter area.
Work flow rate can be calculated by the raw water flow and filters the wash service area. Note that when the
flow rate rises to a certain level, the biological flocculation experience disintegration or dissolution of the filter
or filters will produce flow phenomenon.
In the modeling work should ensure that the filter flow rates below this level.
Temperature factors should also be considered, in the low-temperature region,the sand depth is generally
greater than 2 meters.
Under normal operating conditions, the activity of continuous sand filter can ensures the following effects:
Color: <5 degrees
Algae removal rate close to 100%
|Filtration area m2||Height of sand bed (m)|
How to choose the suitable model:
1.Choose the height of sand bed by inlet and outlet water quality.
2.B type is concrete structures, T type is movable active sand filters; material can be SS304, SS316L,FRP,
high chrome alloy steel, carbon steel (corrosion-resistant) or other specified materials.
Stripping mode: you can select internal circulation or external circulation.
Total phosphorus removal:70~95%(dose flocculant)
Total phosphorus removal:5~20%(without flocculant)
NOTE: To improve the COD and ammonia nitrogen removal, turn to the use, of biological treatment
