Filtration is the most widely used method in the treatment of sludge produced by wastewater treatment. It can consist just in drainage though sand beds or it can be mechanical under vacuum middle or high pressure conditions which require more sophisticated equipment.
Filter press operate applying very high pressures to the cake (from 5 to 15 bars and sometimes even more).
Our filter press is suitable for almost all types of sludge:
1. Hydrophilic organic sludge: inorganic conditioning is often recommended to enable satisfactory cake release due to minimal adherence to filter cloth.
2. Hydrophilic inorganic sludge: the filter press generally requires the addition of lime only.
3. Hydrophobic inorganic sludge: it is very dense and ideal for the filter press. It is dewatered without any preliminary conditioning.
4. Oily sludge: the filter press can be used to treat sludge containing light oils, the presence of grease can sometimes impair the smooth running of the filter, clothes have to be degreased at frequent intervals.
