Process details and effluent characteristics of a rice A work was undertaken to study the process details and effluent characteristics of a rice mill in the district of Sambalpur, Orissa. The milling capacity of rice mill was 10 MT/day. The rice mill generates effluent in an average 100 kl/day from the paddy soaking, parboiling and boiler blow down operations.

TREATMENT OF RICE MILL EFFLUENTS FOR POLLUTION CONTROL The rice mill effluents carry high load of suspended and dissolved organic matters causing serious environmental pollution. Anaerobic digestion which produces biogas is one possible solution. Alternatively, a process of chemical dosing and treatment has been investigated and the experimental results presented.TREATMENT OF RICE MILL EFFLUENTS FOR POLLUTION CONTROLof time the rice mill effluents may cause irreversible changes in the soil and underground water sources, thus affecting both human and plant lives. Typical characteristics of rice mill effluents are presented in Table 1 below. MATERIAL AND MATHODS It is possible to design a purely biological systemETP for Rice Mill | Effluent Treatment Plant for Rice Effluent characteristics of a rice mill vary depending on the type of rice being processed. Majorly it consists of contaminants like: PH, total solids, dissolved solids, TSS, COD, BOD & etc. Dangerous effect from all these contaminants can be greatly reduced by using ETP for rice mill.Current techniques in rice mill effluent treatment The wastewater generated contains a wide range of organic and inorganic toxic contaminants. Table 1 lists the characteristics of rice mill effluent as reported by earlier studies. Variations of pH (4.5–8.5) are encountered owing to different paddy characteristics, the parboiling process and the quality of water used.
