Mechanical dewatering equipment
JD-series dehydrators (hereinafter referred to as “dehydrators”) are manufactured jointly with Tsurumi-Pump Company (Japan).
The JD-series Dehydrator dewaters organic sludge with a “Multi-Disc” system and enables highly efficient collection of solids.
Efficient Dehydration by “Gravity-Filtration” and “Compression”
A number of filtering rollers, each consisting of a stainless steel shaft and multiple thin discs, are placed in two rows - upper and lower. The rollers close to the sludge inlet form the filtration section, whereas the rollers close to the outlet form the dehydration section.
As the incoming flocculated sludge travels through the filtration section, only the filtrate passes through the slits between discs.
The sludge, concentrated at the filtration section, is then transferred to the dehydration section where it is dewatered more. This is achieved by the increased compression, as the rollers are so aligned that their gaps become narrower as the sludge advances.
Since the rollers rotate at a very low speed, the sludge goes without being kneaded or exposed to unnecessary stress like other dehydrators.

The treating capacity varies depending on the characteristics and concentration of the sludge
The general guide for treating rates per 1000 mm width filtering roller is:
It is suggested that model selection be made with an adequate allowance.
The Total Installed Power indicates the total output of the motors mounted in the unit. The equipment outside the product such as the sludge supply pump and polymeric coagulant mixing equipment etc. are not considered.
