Mechanical polyester dewatering fabric is usually deal with large wastewater treatment plants and is used to separate sludge (residual sludge from waste water treatment plants or faecal sludge from on-site sanitation) into a liquid and a solid part.

The principal methods are belt filter presses, centrifuges and chamber filter presses. These techniques are usually sophisticated and rarely cost-efficient for smaller systems to be implemented on community level. The process does not treat the sludge, it only separates solid from liquid parts via polyester dewatering fabric. Both solid and liquid parts still contain pathogens and pollutants.

Dewatering belt removes water from sludge (residual sludge from wastewater treatment plants such as activated sludge systems, or faecal sludge from on-site sanitation such as septic tanks or pit latrines) making it easier to handle and less expensive  to compost (see also small or large scale composting) to transport, to incinerate (see also small or large scale incineration) or to dispose of in a landfill. Dewatering can be done not only with the help of presses or centrifuges (mechanical dewatering), filtration (e.g. in filter bags) but also physical (and biological) processes in drying beds.
