Effluent Sludge Settlement Tanks

Effluent Sludge Settlement Tanks are available from either Polypropylene or High-Density Polyethylene which are selected to suit your specific application. Sludge is a thick soft mud or other viscous liquids is typically the by-product of wastewater treatment, industrial wastewater solids and settled suspension from potable water treatment. It often contains various types of pathogens as well as heavy contaminants, in the case of industrial waste, chemical pollutants. Sludge contaminated by chemical pollutants or heavy metals, demands complex treatment. Other applications are sludge settlement tanks on small sewage treatment plants, the concentration of food and agricultural waste for anaerobic digestion, removal of grit for water reuse on effluent treatment plants and concentration of apple mulch after cider fermentation.

Effluent Sludge Settlement Tanks In Wastewater Treatment

Effluent Sludge Storage Tanks are a key part of operations in a wastewater treatment plant used for storage of raw effluent, treated effluent, final effluent, raw sewage and sewage sludge and an upright tank or conical tank is used to aid decanting/cleaning to a system of multiple tanks. The aim of operating a sludge tank is to hold sludge after it has been removed from the wastewater treatment system, settle out sludge further so more water can be recovered and further digest the sludge before disposing of. Some have aeration and mixing that is delivered by mechanical and electrical means which aids digestion of the sludge that has accumulated.

Some sludge tanks are used only to hold the sludge until it’s taken away. An alternative to this is to use the tanks to concentrate the sludge within the tank at which point the clearer water is removed from the top where there is no longer sludge called decanting. In most plants, the sludge is then drawn from the tank and dewatered through a sludge press which the drier product is hauled off as liquid for disposal off-site.

Customised Sludge Settlement Tanks

In addition to providing bespoke sludge holding tanks and wastewater storage solutions for a diverse cross-section of clients, equipment mounting and customisation of these sludge tank include welded fittings, sockets and flanges. Racking ports allow draining of the water off the sludge while leaving the sediment in the bottom of the cone tank. Other options include industrial mixers liquid level sensor assemblies, fill pipes are available. PN16 and ANSI welded flanges, welded sockets and as well as airtight lids and vents are available to suit your project.
