Aerofloat can assist in sizing and providing a variety of equipment options, including filter press, screw press, centrifuge, belt filter press or gravity tank dewatering.
If you have high operating costs regarding sludge disposal, a mechanical sludge dewatering device should be considered. Similarly, before installing a new wastewater treatment plant, it is important to understand your predicted sludge make and the associated costs. Aerofloat has expert understanding of the different sludge types and can prepare a net benefit analysis for suitable mechanical dewatering options for its clients.
Installation of a mechanical dewatering device can have excellent economical benefits depending on the volume of sludge produced, disposal costs and capital outlay.
Aerofloat’s engineers are expert at designing fit-for-purpose sludge dewatering solutions. Aerofloat offers proprietary and simple gravity sludge thickening tanks, filter presses and other mechanical dewatering options.
The filter press can be used to dewater solids from a number of processes via a plate and frame system using high pressure rams. Typically, a very high solids content (up to ~50%) can be achieved with a filter press.
Filter presses are mainly used for treating liquid solids from chemical treatment processes – such as ink wastes and other types of chemical sludges. They can be used for sewage and other biological waste solids if a solid cake with high solids (low moisture) content is required.
Aerofloat has successfully installed filter presses on multiple sites for the VISY group.
Screw presses are used for sewage and industrial wastewater sludges. It is more compact than a belt press and only requires a polymer mixing and dosing system and a small flocculation chamber at the inlet.
The screw press is a cylindrical tube which has closely coupled fixed plates and rotating plates (alternate plates). The wet sludge is fed into the tube with a mechanical screw with variable pitch. As the wet sludge is pumped into the tube, the relatively clean water flows between the plates and the solids are retained inside and thickened before moving up the tubes. The dewatered solids drop out of the end of the back pressured tube.
Aerofloat works with reputable suppliers for sludge dewatering equipment including belt presses, centrifuges, gravity tank dewatering and more. Aerofloat has several proprietary sludge tank dewatering designs and can assist in installations for new treatment plants as well as stand-alone additions to an existing facility.
