ELODE extracts both free and absorbed water from the sludge producing a final dehydrated product with a moisture content of less than 40~60% (i.e. greater than 40%~60 dry solids content). This ensures maximum dehydration performance with minimum environ- mental impact.
The dehydration by pressure allows to reach better dryness percentages than other dehydration systems (with results close to 30% being able to be higher through a correct conditioning of the sludge). Its main body is made of Q235 high quality steel processed by sandblasting and painted with epoxy primer.
Reducing the moisture content (Mc) of sludge contributes greatly to subsequent treatment and disposal. An ultrahigh-pressure (UHP) and thin-cake-press (TCP) dewatering device was designed to achieve high-dry sludge using technique involving the addition of little or no cationic polyacrylamide (CPAM).
Sludge dewatering is the practice of minimizing waste by volume to prepare for its effective disposal. Sludge originates during the process of treating wastewater before the water can be released back into the environment.
Waste water quality standard is established for waste water discharged from factory or manufacturing sites. In case of effluent into public waters (rivers lakes etc) it is regulated by Water Pollution Prevention Act and the act has effluent standards which are “effluent standard about Harmful Substances” and “effluent standard about living conditions”.
Flocculation is used to treat the sludge reasonably. The principle of gravity dehydration and mechanical extrusion dehydration is used to remove the water in the sludge so that the sludge can be discharged in the form of filter cake.
Dehydration ranges A wide range of water-treatment techniques separate and concentrate the contaminants present in the water rather than eliminating them. Physical physicochemical and biological treatments all generate solid waste or sludge which are mainly water as their solids concentration typically ranges between 0.5% and 5%.
