Environmental Protection Water Treatment Equipment Continuous Sand Filter

Function:
 
Trap organics,suspended solid,colloidal solid,microorganisms in water.
 Remove nitrogen and phosphorus 
 Reduce COD(Chemical Oxygen Demand) in water

Characteristics

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.

Application:
Appliedto the town water supply, water plants, municipal wastewater treatment,
 industrial wastewater treatment, 
recycling cooling water treatment, process water treatment,
 seawater purification, algae-laden water filtration.


Parameter
 
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:
 
SS<5mg/l(dose flocculant)
<10mg/l(without flocculant)
BOD removal:0.3~0.6mg/mgSS
COD removal:.8~1.6mg/mgSS
Color: <5 degrees
Turbidity: <0.3NTU
Algae removal rate close to 100%

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. 
 
SS:<=5mg/l(dose flocculant),
SS:<=10mg/l(without flocculant)
Total phosphorus removal:70~95%(dose flocculant)
Total phosphorus removal:5~20%(without flocculant)
COD removal:20~45%
Ammonia removal:10~20%
NOTE: To improve the COD and ammonia nitrogen removal, turn to the use,  of biological treatment
 
Bio-Filter
1.Continuous sand filter with aeration device
 
1.HSLQ type continuous sand filter is a kind of bio-filter,which designed to remove BOD, NH3-N etc., Unlike 
ordinary type filter,it added aeration device.
 
In addition to the advantages of ordinary filter, DA type continuous sand filter also has a high oxygen 
utilization, while achieving the removal of BOD, NH3-N.
 
The internal structure of HSLQ type continuous sand filter is divided into two parts: filter area and 
biochemical area. Independent functionfor each other,without mutual interference.
 
 
2.HSLQ
HSLQ series denitrification active sand filters
2.HSLQ type denitrification continuous sand filter
Denitrification continuous sand filter is designed specifically for denitrification filter, combine the filter and 
denitrification device together.It is widely used in  renovation and expansion project.
 
Filtering media is quartz sand, which ensure the filtering effect, and biological treatment effect.
Cover will prevent interference of oxygen in the air during denitrification process,
the cover is on the top of filter. 

Cautions for operation:
a.Height of sand bed: Pour the sand down from the vessel wall, don't pass through
 the sand washing device in the middle.
The distance between the lowest point of washing chamber and sand bed level should be 600-650mm.
 The diameter of sand should not bigger than 5mm.
b.Inlet & Outlet pipeline:Check the status of valve,Ensure that the front and rear lifting pump valves,
 inlet and outlet valve are all open; to ensure the smooth flow of the overflow pipe.
c.Ensure the valves in air pipe are all opened, stripping meter close to the smallest scale,
 to prevent damaging the glass rotor by sudden air supply.
d.open the valve of sand washer pipeline, adjust the level to the middle, 
make sure the water level is below the weir level 10-30mmm.
e.Control the flow rate of filtration and cleaning of gas, water, mixing sand and quartz sand settling velocity by adjusting the degree of opening of the inlet valve and the air valve. 
 
Maintenance:

1.If the downtime is less than 3 days,don't drain away the residual water
2.If the downtime is during 3-15 days,drain away the residual water on the day of closing filter,in avoid of sea sand 
hardening,algae growing
3.If the downtime is more than 15 days,drain away the residual water,and inject the clean water  from the top of filter 
to wash the sand inside the tank.Don't stop until you get the clean water from the bottom of tank.
