SS304 Gravity Static Screen Hydro Sieve for Wastewater Solid Liquid Separation

A static screen is a non-powered solid-liquid separation device used for wastewater pretreatment. It removes suspended solids, fibers, food residues, hair, plastics and other screenable materials from wastewater before the water enters downstream treatment equipment. The system normally consists of an inlet distribution chamber, a curved wedge wire screen, a filtrate collection chamber and a solids discharge section.

A static screen is commonly installed: Before an equalization tank, Before a wastewater lifting pump, Before a dissolved air flotation system, Before biological treatment, Before sludge dewatering equipment, In process water recovery systems, At the inlet of an industrial wastewater treatment plant. Its main purpose is to reduce the solid load entering downstream equipment and minimize blockage, wrapping and mechanical wear.

Static screens are widely used in: Slaughterhouse wastewater treatment, Meat and poultry processing, Seafood processing, Fruit and vegetable processing, Food and beverage production, Pulp and paper mills, Textile wastewater treatment, Livestock and dairy farm wastewater, Brewery and starch production, Municipal sewage treatment, Industrial process water filtration. They are especially suitable for wastewater containing fibrous, granular or easily screenable solids.

Common slot sizes include: 0.5mm-6mm. Customized slot sizes can also be supplied according to the wastewater characteristics and the required separation efficiency.

No. A smaller slot can improve the removal of fine solids, but it may also: Reduce hydraulic capacity, Increase the risk of blockage, Require more frequent cleaning, Increase the required screen area, Cause a higher inlet water level, Reduce performance in oily or sticky wastewater. The correct slot size should balance removal efficiency, hydraulic capacity and anti-clogging performance.
