Abstract: The study was concerned in problems solving and prevention of red color changingin wastewater of food processing industry. The experiments were divided into 4 parts ascollecting of secondary data from food processing industry in Bangkok and Samuthprakarnareas, analysis of red color changing wastewater, treating of red color wastewater by chemicaland physical process and suggesting of treatment process for solving red color problem.The results showed that almost of the factories used the stabilization pond oranaerobic filtration systems for treating the wastewater. Of these, two of them showed the redcolor in the wastewater as seafood canning factory (CN-03) and cold storage factory (CS-10).For the determination of the red color wastewater properties, the wastewater of pondN0.3 of wastewater treatment plant of factory CS-10 and pond N0.2 of wastewater treatmentplant of factory CN-03 showed the highest results in red color intensity. The COD, BOD, pH,SS, TKN, Phosphorus and Chloride concentrations in pond N0.3 of wastewater treatment plantof factory CS-10 were 765 mgll, 428 rngll, 6.9-7.8, 294 mgll, 156 mgll, 21.6 mgll and 327 mgll,respectively, for the factory CN-03, the COD, BOD, pH, SS, TKN, Phosphorus and Chlorideconcentrations in pond N0.2 were 791 mgll, 387 mgll, 6.9-7.7, 280 mgll, 167 mgll, 27.5 mg/land 433 mgll, respectively.For the treatment of red color in wastewater, four types of experiment were carriedout. First experiment were continuously aeration without chemical feeding and continuous feedof KNO, or FeCl, at the flow rate of 30 mgll and 4 mgll, respectively in the wastewater withcontinuously adding of raw wastewater of 2 Wd. After 10 days incubation, COD, color intensityand SS removal efficiencies were 72 %, 37 % and 49 %, 85.1 %, 3 1.2 % and 49 % and 76.3%, 22 % and 45.8 %, respectively. Second experiment were comparison of one time adding ofKNO, or FeCl, at 30 mgA and 4 mgll, respectively and continuous aeration, The COD, colorintensity and SS removal efficiencies were 84.2 %, 46.7 % and 55.7 %, 86.1 %, 33 % and 35.5% and 85.9 %, 26.8 % and 36.6 %, respectively with fully aeration, KNO, treatment and FeC1,treatment, respectively. Third experiment were continuously feeding of KNO, or FeC1, and onetime feeding of KNO, or FeCI, .The COD, color intensity and SS removal efficiencies were 48.7%, 41.3 %, 37.7 % and 45 %, 58.4 %, 49.7 %, 47.3 % and 50.7 % and 56.5 %, 47.6 %, 48.4 %and 50 %, respectively with one time and continuous feeding of KNO, or FeCl,, respectively.Fourth experiment were with and without KNO, or FeCl, adding (one time) under fully aeration.The COD, color intensity and SS removal efficiencies were 75.4 %, 76.9 % and 75.4 %, 84.3 %,85 % and 84.5 % and 89.3 %, 91.7 % and 90.5 %, respectively with fully aeration, KNO, addingand FeC1, adding, respectively.For the selection of the type of wastewater treatment plant was suitable for treatingthis kind of wastewater, aerobic-aerated lagoon or complete activated sludge system wereselected. However, anaerobic pond facultative pond or anaerobic filter could be used for removalof the high concentration of COD at the first step for reduction of construction cost andoperating cost. But some chemical such as KNO, or FeCl, should be added for prevention of redcolor bacteria.
