Belt Filter Press is often applied in wastewater treatment plant sludge dewatering process and it is one of the most cost effective options regardless of the type of sludge feed into the systems. There are several combined processes added into one unit and it involves different applications such as chemical conditioning, gravity drainage and mechanical shearing and compression effect to remove water and dry up the sludge. Today, belt filter presses are widely used and it has become a standard for general wastewater...
Mining sector is: beneficiation of metals (iron, nickel, copper, zinc), beneficiation of non-metals beneficiation of noble metals (gold, silver, platinum, palladium), coal processing, calcium carbonate and minerals in general (silicates, clays, kaolins, etc..)
Membrane press filter is composed of diaphragm plates and van plates. The feeding pump press the slurry to enter the filter chamber.When the filter material become after filter cake through the filter cloth.Then gas will be guided into septum,giving enough pressure to solid and lowering its water content.
DIEMME Filtration has the correct solutions for all problems of slurry - sludge dewatering, because every DIEMME FILTRATION filter press, is projected in connection with the chemical physical characteristics of the sludge.
Peristaltic pumps are proven performers in water and waste treatment solving problems including: Dosing and metering treatment chemicals and reagents including ferric chloride (“Ferric”), sodium hypochlorite (“Hypo”), chlorine water, lime (Kalic or Kalkmilch), caustic soda, powder activated carbon and polymers, sludge transfer, filter press feeds.
For industrial and municipal treatment plants; Chemical scrubbers, biological towers and adsorption systems to remove hydrogen sulfide, mercaptans, other organic sulfur compounds and ammonia from digesters, pump stations, ponds, grit and screening works, sludge filter presses and dryers. Special Wet Electrostatic Precipitator for sewage sludge incinerators. Stripping ammonia and other volatile compounds. Decarbonization removal of carbon dioxide from wastewater.
In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.
