Hengda’s 1250mm PLC filter press has 22 gasketed filter plates with a capacity of 32 CF. It is used in a county owned domestic waste water treatment plant in Northern California to dewater biological aerobically digested solids. It replaces an older press that has saved the county about $12K/month liquid trucking and disposal costs.
This filter press is electric hydraulic with an automatic plate shifter that can be used in semiautomatic mode to allow for cake scraping. The shifter to reduce labor , 25% greater capacity, and eliminating wicking [gasketed plates] motivated the upgrade.
