Screening is the first operation at any wastewater treatment plant. The screening process involves the removal of large non-biodegradable solids that frequently enter a wastewater works, such as rags, papers, plastics, latex, tins, containers and wood.
Efficient solids removal protects the downstream plant and prevents any possible damage, unnecessary wear tear, pipe blockages and the accumulation of unwanted material that will interfere with the required wastewater treatment processes.
The following fine screening solutions are available:
- BANDGUARDTM high efficiency band screens used in sewage treatment plants around the world.
- FINEGUARDTM is utilised for fine screening and removes floating and submerged debris. It is commonly installed in inlet works downstream from coarse screen or bar screens and prevents clogging and damages from components downstream.
- SPIROGUARD®Compact Cleaner (CC) Screen is designed as a stand-alone unit for pumped flow applications. SPIROGUARD® Channel Screen (CS) Screens can be installed for a variety of flow rates and upstream and downstream water levels. The angle of inclination can be adjusted depending on your concrete channel specifications.
- DRUMGUARDTM is a robust screen that can be used on water and sewage applications. DRUMGUARDTM is designed to automatically and reliably filter influent water and discharge recovered debris or marine life into the appropriate handling trough. Over many years the cup screen particularly has been used on sewage works for fine screening and sea outfall use. Both drum and cup screen cylinders can be fitted with perforated stainless or Ultra-high-molecular-weight polyethylene (UHMWPE) for sewage work and woven wire normally for water intakes.
