Effluent Sludge Storage Tanks
Enduramaxx manufactures effluent sludge storage tanks for treatment of sludge in wastewater application. Sludge is a thick, soft mud and typically the by-product of wastewater treatment, industrial wastewater solids and settled suspension from potable water treatment often containing various types of pathogens. Typical applications for 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. Sludge contaminated by chemical pollutants or heavy metals and demands will require a more complex treatment.
What is Sludge Thickening?
Sludge thickening is the reduction of volume by up to 80 %, which can be reached with sludge thickening before further treatment is required. This is where wastewater treatment plants drive the sludge off regularly and usually takes place directly in the sludge storage tank.
What is Dewatering?
Dewatering is the further reduction of the sludge amount after the thickening as the liquid still must be dewatered to a dry and porous form. Dewatering is generally by machine processes using a filter press and centrifuge, with the aid of chemical treatment flocculation, biological treatment, and pH control. Enduramaxx’s range of bulk chemical tanks, dosing tanks, polymer mixers, coagulation and flocculation equipment are also available online.
Dished Base Conical Sludge Tanks
Dish based or conical sludge tanks are a vital part of operations in a wastewater treatment plant used for storage of raw effluent. Treated effluent, final effluent, raw sewage and sewage sludge are also stored in vertical or conical tanks to hold sludge after it has been removed from the wastewater treatment system, settle out sludge further so more water can be recovered. Conical tanks have one main advantage over standard flat base sludge tanks which is that that the sludge can be drained through the centre. Some have aeration and mixing that is delivered by mechanical and electrical means which aids digestion of the sludge that has accumulated.
Features of Dished Base Settling Tanks
- Cone base enables the tank to be cleaned and drained
- Decanting/racking ports allow for liquor/effluent removal at different levels
- Rotationally moulded, UK stabilised PE construction for many years of outside use.
- Available with different colours – black, dark green, natural – translucent to view level in the tank)
Equipment Mounting, Pipework and Customisation for Sludge Tanks
These settling tanks are available with customised fittings and flanges including BSP inlets and outlets, PN16 and ANSI flanges, welded sockets, vents, liquid level sensor assemblies, fill pipes and suction pipes, as well as side access hatches.
