SUBSTAINABLE TECHNOLOGY FOR TREATMENT OF BATIK WASTE EFFLUENT

摘要

The treatment system known as SMBR for treatment of batik waste effluent, said system combines the activated sludge process with a semi permeable bio-membrane submerged in the process water that is capable of treating and filtering particulate waste constituents from the mixed liquor solution of batik effluent, thus subsequently provide treated batik effluent of high quality, reusable and particle free effluent. The semi-permeable membrane (bio-membrane) (7) has a pore size of approximately 6 nm to provide permeate comprised of batik effluent compliant to the Standard A of regulations stipulated by the Department of Environment (DOE) Malaysia. Air scouring (8) is maintained in the body of water in the range of 1 LPM to 4 LPM for purpose of minimizing membrane fouling, subsequently lead to relatively stable suction operation at low transmembrane pressure (TMP below 1 bar), lesser hydraulic retention time (4-24 hours) and longer backwash requirement (30 days). Operational conditions of MLSS and SRT were maintained at the range of 4000 mg/L to 7000 mg/L and 16 days to 30 days, respectively. Besides that the system is also practical, compact and easy to upgrade.
