Case History for Hengda Filter Press
A power plant is located in northern California operates a 50 megawatt waste burning power plant. They use a cold lime water softening process to soften their processed water, R/O, cooling tower makeup, gas scrubber, etc. The solids generated from the process are primarily calcium carbonate and magnesium hydroxide. The original design was for belt press dewatering, which was difficult to operate and was abandoned. The wet solids were dealt with in another way, until about 2012 when the dewatering of this waste stream became important.
A local engineering company was contacted and samples of the waste were lab tested for feasibility confirmation. Full scale pilot testing would have been performed if the lab testing wasn’t extremely successful.
Based on the solids generated by the plant, a relatively small 15 cu ft., 800 mm plate size, 32mm cake thickness, 28-plate gasket press was supplied. The plates supplied have a unique handle design with rollers on one handle side to facilitate easy movement of the plates without a shifter. Click here to read full case study.
