Definition and Working Principle

LBSF-80 Continuous quick sand filter,Grit Removal System , backwash sand filter 1


LBSF model Continuous Backwash Filter is an up-flow, moving bed filter that is constructed with various media depths for different applications and configurations.

It is a set of flocculation, clarification, filtration as one of the continuous operation of the sand filter .representing the highest level of continuous filtration technology. Through the built-in flushing system continuous flushing, because there is no need to stop recoil,its operation and maintenance is very easier. It is widely used in drinking water, industrial water, sewage deep treatment and center water re-circled treatment


How it Work

Raw water enters near the bottom of the tank by means of a stainless steel water distributor. Suspended solids are filtered out as the raw water flows up through the media bed. As the filtrate reaches the top of the filter, it passes over the effluent weir and is discharged. A portion of the filtrate is diverted through the sand washer and used for cleaning and transferring the waste solids.

The filter employs a backwash rinse that is performed continually while the tank is processing water. An air lift pump, located at the center of the module, draws the media from the bottom of the filter up into the wash box. As the media is released into the wash box, it falls into the sand scrubber where the filtered solids are separated from the sand. From there, the filtrate carries the solids out as waste (backwash). The washed sand falls down onto the media bed for continued use.



The LBSF model continuous backwash filter can be applied in both municipal wastewater and industrial water treatment processes.

Whether you need reuse quality water, nutrient removal, industrial water treatment, or raw water treatment, Loren 's sand filter delivers unmatched effluent quality, meeting the highest of environmental standards.

Comparison to Traditional Mechanical Filter

Item Continuous Sand Filter Traditional Sand Filter
Type continuous Lowe Flow Pressure
Efficiency Stable Change as per period of filter and backwash
Head lost Small with Stable Big Change as per period of filter and backwash
Middle water tank None Need
Reflux Pump None Need
Filer process continuous Sequence run with stop machine for back washing
Control device None Complex with each process set one auto valve and press gauge
Operation Simple Complex
Waste water Adaptability Good Limited due to backwash SS on its filter layer
Backwash process Constant With abnormal overload under huge backwash water volume
Flush Effect Thorough with no angle May with parts no flushing
Maintenance charge Extremely little Bigger work
