Water, is one of the prime, element, involved, in, the, creation of healthy life as well it’s development. Since, water, is, such, an essential , resource, for, survival, of, both, plants, and, animals, hence, it’s our, responsibility, to, manage, this, resource, for, the, sustainable, benefit, of, all, present, and, future, living, element., Because of the, high, pollution, potential , sugar, industry, is, considered, as, one, of, the, topmost, pollution, creating, industries, affecting, our, environment and ecosystem .Wastewater, from, sugar, industry, bears, complex, properties, and, its, treatment, is, considered, as, one, of, the, difficult , tasks, for, environmental, engineers, in, terms, of, its, treatment, as, well, as, using it again for a particular purpose ., The, brown, colour,, high, temperature,, low, pH,, high, COD,, high, BOD,, TDS,, odour, problems, and, excessive, percentage, of, dissolved, organics, and, inorganics, are, major, properties, of, the, sugar, industrial, effluent., This, effluent, if, discharged, untreated,, poses, problems, for, both, marine, and, terrestrial, ecosystems., The, cost, effective, and, economical, treatment, of, sugar, industrial, waste, is such a difficult task,,therefore, an, appropriate, and, cost-effective, method, to, meet, the, discharge, standards, is, needed., The, aim, of, this, paper, is, to, review, the, hybrid, anaerobic, baffled, reactor, for, the, treatment, of, sugar, industry, wastewater, and, compare, it’s, performance, with, respect, to, the, ABR., The, results, presented, in, this, paper, are, from, case, studies, done, on, a, laboratory-scale, Hybrid, ABR, &, ABR, treating, sugar, industry, wastewater, at, different, Hydraulic Retention Time ., The, purpose, of, this, study, is, to, see, the, performance, of, an, anaerobic, baffled, reactor, (ABR), and, a, hybrid, ABR, (HABR), for, the, treatment, of, sugar, industry, under, ambient, conditions, and, compare, the, ability, of, the, two, systems, to, meet, effluent, discharge, standards., In, steady, state, the, COD, removal, efficiencies, of, the, HABR, were, 2.2%, greater, than, those, of, the, ABR, at, all, HRTs., The, HABR, met, COD, and, BOD5, effluent, discharge, standards, using, a, 24-hour, HRT,, while, the, ABR, achieved, these, standards, only, with, a, 48-hour, HRT., The, HABR, was, found, to, be, suitable, for, conventional, sugar, industry, wastewater, treatment.
