บทคัดย่อ (EN): Various types of anaerobic digesters are available to treat Ribbed Smoked Sheet (RSS) processing effluent which causes environmental pollution because of the organic 122 constituents present in it. The anaerobic digesters developed for this have efficiencies ranging from 80-95% in BOD and COD reduction. The water coming out after treatment in these anaerobic digesters still contains degradable matter and therefore pollution parameters are not within the limit specified for safe disposal. Therefore, it warrants further treatment. At present in RSS processing industry this is being per-formed aerobically in oxidation ponds. Major limitations of this kind of treatment are slow process and requirement of large area. Activated sludge process could reduce the pollution load in a shorter period of time which needs lesser space. Even though the conventional activated sludge treatment using fixed or floating aerator is very quick and efficient, it is expensive due to high electricity consumption. Therefore diffused aera-tion, an effective activated sludge processing mean which produces fine air bubbles that give greater oxygen transfer was experimented. In the present study, an aerobic activated sludge system with diffused aeration technology was designed. Developed and evaluated. The system consisted of a rectan-gular tank with 9 disc type diffusers having a diameter of 9 inch placed in the bottom of the tank at a distance of 60 cm from each other. The diffuser is made of EPDM with a rubber diaphragm at top having large number of fine holes. Air is pumped in to the dif-fuser using one HP Twin Lobe Rotary Air blower. Air is released through the fine holes in the diaphragm of the diffuser as fine bubbles. This oxygenation method is much more efficient in transferring air because this creates s larger transfer surface area per unit volume of added air. The diffuser system is highly resistant to clogging and corro-sion and fit for wide range of air flow. These fine bubble membrane diffusers can reduce the power required to transfer oxygen by up to 50%. The pressurized movement of air bubbles provides a water stirring effect also. In the study, the partially digested effluent from anaerobic digester was fed to the aeration tank at a controlled rate to maintain HRT of 24 hrs and subjected to oxy-genation by diffused aeration. The treated water from the aeration unit was then sub-jected to sedimentation to remove settable solids. The water coming out after aeration and sedimentation was analysed periodically for various pollution parameters like BOD, COD, total solids dissolved solids and pH as per standard procedures. The combined action of the aeration and sedimentation reduced the COD, BOD, TS and DS of the feed effluent by 58.5%, 88.6%, 10.3% and 2.7% respectively. The treatment could bring down the major pollution parameters vis. pH, COD and BOD to the specified safe limit. This proves that the post anaerobic treatment of RSS processing effluent using diffused aeration technology is an effective and efficient methodology for the treatment of RSS processing waste water.
