Study on Production Wastewater in Water Treatment Plants by Submerged Micro-Filtration Membrane

Abstract:

To verify the feasibility of micro-filtration membrane process to treat the water treatment plants production wastewater, a submerged polypropylene membrane module was applied in a test pilot plant. It was found that membrane process had remarkable characteristics of stable operation, high water quality and the membrane module were needed to chemical medicine washing as trans-membrane pressure (TMP) to 36 Kpa after running across 41day. The operation cycle was the best period for 20 minutes (filter 18 minutes, backwash 2 minutes). Membrane filtration water was showed as turbidity of 0.1-0.2NTU, COD_Mn generally less than 3mg / L, COD_Mn removal efficiency of 60% -80%.^{Fe2 +}, Mn^{2 +},Al^{3 +} and THMFP of membrane filtration water were lower than the national drinking water health standards.
