Nano/submicrometer-emulsion oily wastewater treatment ...

Owing to the underwater oleophobicity of wood-,PVA, and its outstanding desalination capacity, the device is expected to purify oily ,wastewater under, solar irradiation. During the purification process, oil droplets are intercepted in the bulk ,wastewater,; meanwhile, water and ions are pumped to the evaporation layer (CNT layer) continuously through the wood-,PVA,.

Domestic wastewater treatment using immobilized sludge ...

This study is an initial approach for developing a small domestic ,wastewater treatment, process using immobilized sludge. The feasibility of sludge immobilization by the ,PVA,-boric acid method was examined. The activity and stability o f the immobilized sludge were measured. The potential of the immobilized sludge process for small scale domestic ,wastewater treatment, was explored. In this ...
