There are a lot of kinds of dehydrator for sludge arises from wastewater treatment plants. Among them, belt press dehydrator holds sludge in between two filtering clothes and dehydrates by squeezing and filtering it.   ■ Belt press dehydrator   Belt press dehydrator has a structure in which two filtering cloth hold sludge in between […]

There are a lot of kinds of dehydrator for sludge arises from wastewater treatment plants. Among them, multi disc dehydrator performs dehydration and filtering with filtering devices configured by combination of moving discs and fixed discs put next to each other.   ■ Multi disc dehydrator   The filtering devices configured by several stainless discs […]

There are a lot of kinds of dehydrator for sludge arises from wastewater treatment plants. Among them, screw press dehydrator performs dehydration by squeezing and filtering while screw blades are rotating. ■ Screw press dehydrator A screw press dehydrator is configured by screw blades and mesh patterned cylindrical screens around it. Space between the blades […]

There are a lot of kinds of dehydrator for sludge arises from wastewater treatment plants. Among them, filter press dehydrator is a dehydrator which dehydrates sludge by pressing and injecting into limited space called filtering room. Sludge dehydrated by the filter press tends to have lower moisture content compared with other types of dehydrators. Also, […]

Sludge generated in wastewater treatment plants pass through condensation process and conditioning process, then next process is dewatering. In dewatering process, pre dewatered sludge which have moisture content of 95% or higher is separated into solid matters and liquid, and solidified by squeezing water out. By this process, sludge in liquid state becomes cake-like state  and […]
