Shaftless Screw Press Filter Screen - China Suppliers & Factory for Efficient Solid Dewatering Solutions
Product Description
This kind of SCREEN offers the waste water filtration and the transport of the effluents for the stocking, in a practical and efficient package. The machine can be installed inclined (between 35 ° and 45 ° depending on the needs) into a concrete channel or in a stainless steel tank to receive the wastewaters from a fixed pipe.
SCREW SCREEN COMPACTOR
The SCREW SCREEN COMPACTOR is the more complete variant, with a compactor zone next to the discharge, which allows an important reduction in weight and volume of filtered waste (up to 50% less).
Filtration Zone
Made up by a holed sheet (circular holes from 1 to 6mm) which filters the wastewater holding back the waste. Within this zone, the shaftless screw is equipped with brushes for cleaning the filtration. An optional washing system is activatable via manual or solenoid valve.
Transport Zone
Composed of an auger and the continuation of the shaftless screw. When activated by the gear motor, the screw rotates on itself, picking up and transporting waste efficiently until it reaches the discharge outlet.
Applications
This is a kind of advanced solid-liquid separation device in water treatment, which can continuously and automatically remove debris from wastewater for sewage pretreatment. It is widely applied to water treatment projects across various municipal and industrial sectors:
Municipal sewage treatment plants & pumping stations
Residential quarters sewage pretreatment devices
Waterworks & power plants
Food, fishery, butchery & wine industries
Textile, printing, dyeing & curriery sectors
Paper mills & general water treatment projects
Frequently Asked Questions
What is a Screw Screen Compactor?
A Screw Screen Compactor is an integrated wastewater treatment device that combines filtration, transport, and compaction of screened waste. It features a compaction zone next to the discharge that can reduce the weight and volume of filtered waste by up to 50%.
How is the screw screen installed?
The machine can be installed at an incline angle between 35° and 45°, depending on the specific requirements of the facility. It can be mounted directly into a concrete channel or inside a stainless steel tank to receive wastewater from a fixed pipe.
What is the filtration range of the screen?
The filtration zone consists of a holed sheet with circular holes ranging from 1mm to 6mm in size. This design efficiently holds back solids while allowing the wastewater to pass through.
How does the self-cleaning mechanism work?
Within the filtration zone, the shaftless screw is equipped with specialized brushes that clean the holed screen as it rotates. Additionally, a washing system can be activated manually or through an optional solenoid valve for enhanced cleaning.
Which industries can use this solid-liquid separation device?
It is widely used in municipal sewage plants, waterworks, power stations, and various industrial wastewater operations including textile, food processing, paper mills, fisheries, breweries, tanneries, and slaughterhouses.
