Chamber filter press for solidification of pile foundation waste sludge
2022/10/20 1090
Box type sludge filter press is widely used for wet work hole filling piles along the coast of China where the foundation soil is mainly clay, sand, silt and silty soil. However, a large amount of slurry will be generated during the construction process, which will seriously pollute the surrounding soil and environment and reduce the degree of civilised construction on site if it is not abated in time...

River sludge filter press (mobile slurry dewatering and curing equipment study)
2022/10/20 1490
River silt filter presses are used for river dredging, but they all face the problem of how to deal with the silt. Silt usually contains a large amount of organic matter, pathogenic microorganisms, heavy metals, and nitrogen, phosphorus and other substances, because of its own poor permeability, solidification difficulties, so it is easy to pressure rheology, not easy to transport. Traditional dredging slurry...
