A sludge holding tanks is needed to store sludge from whatever source. The sludges can be primary sludge, activated sludge, imported sludge and scum. The sludge may be contaminated with heavy metals; it might contain chemical pollutants that require complex procedures to treat. There might be pathogens, microbes that need biological treatments and sewage, food and drink manufacturing and agricultural waste may require other processers.
During the treatment of wastewater, the water content is reduced, leaving behind the sludge. This still contains a certain percentage of water, but as it settles out, more water can be removed. Further biological treatment of the sludge may take place, or the sludge tanks may be used simply to store the sludge before it is removed.
The separation and recycling of the elements of sludge are further important processes as part of the potable water treatment process.
Sludge Buffer Holding Tanks have various uses. The blending and homogenising of very concentrated primary or secondary sludges are commonly carried out in sludge buffer holding tanks. The sludge is mixed with the appropriate thickening chemicals, and dewatering carried out.
The volume of the sludge can be reduced by up to 80% and is usually done by dewatering.
The tanks can be customised to suit many wastewater treatment systems, with welded fittings, frames for easy access, pipework and flanges, adapted to existing equipment.
Racking ports can be used to drain off the water while leaving the sludge settled at the bottom of the tank – and a conical tank makes removal of the sludge easy. Vents or airtight lids are further options available at Enduramaxx – you can see our range here, and we can often supply tanks ready-made for fast delivery.
Our sludge buffer tanks are designed to hold and store sludge in all the various stages of wastewater treatment. They are made from the highest quality Polypropylene or High-Density Polyethylene, whichever is most suitable for sludge storage.
Our range of sludge tanks includes those designed for all stages of the wastewater treatment process, including the following:
Treating sludge can be complex, and removing and recycling the elements like heavy metals, nitrates, phosphates for further use as well as purifying the water means that there must be sludge holding tanks that are be suited to each stage of the process. There is more information about sludge holding tanks here.
