SELF-CLEANING INTAKE SCREENS FOR INDUSTRIAL APPLICATIONS
An intake screen is generally used for the extraction and filtration of raw water from rivers, lakes, streams and reservoirs for the purpose of providing for process water, cooling water and other critical water applications.
Also known as a raw water intake, inlet screen, drum screen, pre-filter, pump screen or coarse screen, they may take the form of either a cylindrical drum or flat profile design using a very low slot-through velocity to eliminate any impingement of debris onto the screen surface.
The AWMA Self-cleaning Intake Screen solution is custom designed to protect critical and high value assets from costly blockages and damage due to unwanted debris matter. Whether it’s for a power generation, water treatment, desalination, hydrocarbon processing, irrigation, or other industrial application, the AWMA self-cleaning intake screen system is well suited.
The screen material and design dictates very low maintenance requirements. Manufactured from corrosion resistant stainless steel wedge wire, the screen is extremely strong and durable.
Its self-cleaning functionality utilises a rotating screen cylinder (powered or self-propelled) with internal and external brushes to eliminate any debris loading or suspended solid build-up without the need for additional air or water auxiliary cleaning equipment. This intake screen solution provides the perfect replacement for an existing static screen that requires excessive cleaning.
