Static Screen Wastewater

March 21, 2022 Sieve Bend Screen

Static Screen also known as arc screen, slit screen, inclined screen, inclined grille, hydraulic grille, curved grille. It is mainly used for pre-dehydration, dewatering, de-intermediation operations, material or fiber classification and recovery of liquids. It is a kind of non-power grille decontamination machine, which can be applied to the separation of solid SS and liquid of various waste water properties.
Using the gravity of the water flow itself to work, no energy consumption; a single machine handles a large amount of water, is not easy to block, and is easy to clean. The whole machine is made of stainless steel, with high mechanical strength, no deformation and long service life.

Working principle

The main body of the Static Screen is a stainless steel arc or plane filter screen surface scientifically made of wedge wire steel rods. The wastewater to be treated is evenly distributed on the Static Screen surface through the overflow weir. The drainage is smooth and not easy to block; the solid matter is retained, the filtered water flows out from the gap of the sieve plate, and at the same time, under the action of hydraulic force, the solid matter is pushed to the lower end of the sieve plate for discharge, so as to achieve the purpose of solid-liquid separation.

Different types

1. With backwash + press system + vibration device

After filtration and press, the solid water content is lower. The vibration device is more advantageous to separate the adhesive solids. Usually applied in sugar industry.
