Environmental Protection Water Treatment Equipment Continuous Sand Filter

Basic Info

Model No.:  HSLQ-T

Product Description

Model NO.: HSLQ-T Motive Force: Electric power Performance: Efficient Filtration Material: Carbon Steel,Stainless Steel Trademark: PEIDE Origin: China Usage: Environmental Protection Style: Vertical Certification: ISO,SGS Application: Water Filtration Specification: ISO9001: 2008 HS Code: 8421219990
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:
