Treatment of Waste Seawater from Shrimp Farm Using a Photocatalytic Membrane Reactor

Abstract:

To treat the waste seawater from shrimp farms, TiO₂ powder photocatalysis and ceramic membrane filtration technologies were integrated to form a photocatalytic membrane reactor (PMR). PMR performance was investigated and real waste water sample was treated under the optimum operation conditions. Results indicated that TiO₂ powder with mean particle size of 0.27 μm could be separated successfully with α-Al₂O₃ membrane with pore size of 0.05 μm, the permeation flux was 432 Lhr^-1m^-2 under pressure of 0.05 MPa. Wastewater was treated with three different catalysts involving 2 g of TiO₂ powder, 2 g of TiO₂ powder combined with 5 ml of H₂O₂ (30%), and 2 g of TiO₂ powder combined with 5 ml of Fenton agent for per liter of wastewater, the corresponding COD_Cr removal rates were 15.67 %, 25.19 % and 40.67 % separately.
