Structure of JD series -1
Number of filtering rollers, each of which consists 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, and the rollers closed to the outlet form the dehydration section.
Structure of JD series -2
Number of filtering rollers, each of which consists 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, and the rollers closed to the outlet form the dehydration section.
Structure of JD series -3
Number of filtering rollers, each of which consists 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, and the rollers closed to the outlet form the dehydration section.
Structure of JD series -4
Structure of JD series -5
Basic flow chart
Dehydration flow
Operation adjustment -flapper
- Adjust pressure adjuster of flapper for the suitable dehydration. Adjust it in the range between 0 - 40 mm depending on situation.
- When screwing up to the end, it becomes to be max. 0mm. Standard pressure adjustment is 20mm.
Recommended operation setting of inverter for rollers
Filtration part: driven by No.1~5 gear motor
Dehydration part: driven by No.6~7 gear motor

Point of Patent *Please refer attached handout
Fig. 3: Constitution of the disk
Assembling is possible easily at low cost by interposing smaller disc and larger disc on the protuberance of PPS-resin precision ejection molded article.
Fig. 4: Bigger disc is possible to sliding
This constitution makes it possible to prevent clogging of the filtration gap with effect.
