Abstract
The sugar industry has an important role in economic growth. However, the wastewater generated by these enterprises contains a significant amount of pollution. Sugar industry wastewater poses a pollution hazard in both aquatic and terrestrial habitats if released without treatment. The sugar business is one of the most polluting industries in terms of effluent volume and characteristics. The basic purpose of this study is to expose the main factors affecting sugar factory effluents, their properties, and their treatment. The study used the Kom-Ombo sugar factory as a case study. Kom-Ombo sugar factory produces a large volume of wastewater that is significantly contaminated with suspended particles (500-800 mg/l) and organic matter (2000- 8000 mg COD/l). As a result, these wastewaters cannot be discharged directly into the environment without causing harm and must undergo physico-chemical treatment to remove suspended solids before being treated biologically to remove soluble organic matter. Hence, it requires an appropriate treatment to maximize the reuse possibilities. A laboratory-scale sequencing batch reactor (SBR) and moving-bed biofilm sequencing batch reactor (MBSBR) system were conducted. To fill the MBSBR Bio-Ball and KMT K5, two types of biofilm carriers were used. Three operating were investigated at hydraulic retention time (1, 2, and 3 days), Hydraulic loading rate (HLR) of (0.3, 0.15, and 0.1 m3 /m2 /d), and discharge of (30, 15, 10 L/d). The effect of carrier type was evaluated in addition an overall comparison between systems were evaluated. The synthetic feed composition of sugar factoryeffluent was COD = 7000 mg/l to achieve system performance in terms of COD removal. A ceramic membrane was used as advanced treatment. The ceramic fabricated from local materials. Ceramic membrane performance was evaluated at different pH values (5, 7, and 9). Experimental results showed that increasing HRT significantly improved system performance. Overall, MBSBR with Bio-Ball reached high COD removal at hydraulic retention time of 3 days, one cycle per day, and discharge of 10 l/d. Furthermore, a high loading rate has negative effects that necessitate post-treatment for reuse of treated water. The results revealed a chemical oxygen demand reduction of up to 50% from industrial wastewater with low COD values. Also, the removal efficiency increased with increasing pH. The integration of MBSBR followed by a ceramic membrane is a promising process for sugar factory effluent reuse.
