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.
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.
WEAVEinMotion process belts are effective and robust cores for belt presses which are particularly efficiently acting systems for dewatering sludges and fruit mashes. A decrease in transport, disposal and recycling costs is obtained thanks to the reduction in volume achieved.
Both economic and ecological demands make maximum dewatering of sludge a most crucial step in the process flow, especially for the pulp and paper industry with their large quantities of sludge to handle. A highest possible dry content of dewatered sludge minimizes weight and volume, hence achieving the following objectives: reduction of transport and disposal cost. high heating value for incineration without additional fuel. With the sludge dewatering systems including both AKSE S disc thickener and AKUPRESS BX...
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...
IMPROVED BIOSOLIDS/ BIO SLUDGE DEWATERING WITH WILSA® CONDITIONING
The WILSA ElectroWave™ effect can be used to condition polar fluids to alter their physical
properties, improving several chemical and physical processes.
- Reducing surface tension to improve the ability of water to repel solids - break physical / chemical emulsions
- Increasing the contact angle of water - improve coalescing of solid particulate toaccelerate phase separation
- Lowering the viscosity of water - reduce friction of flocculated...
Sludge by-products from the metalworking industry have a high potential for recycling. Prolonged grinding processes can generate large amounts of highly valuable, alloy-rich sludge; consisting of metal powder and cooling lubricants. Inside our VacuDry system, the thermal separation of the liquids (hydrocarbons, eventually water) and solids (metal powder) takes place in an oxygen free atmosphere. This absence of oxygen ultimately eliminates material degradation by oxidation, and self-ignition or explosion risks....
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.
