Abstract

Background: Industrial wastewater has brought a major anxiety for human beings. The present study was conducted to determine the industrial wastewater of a match factory in Tabriz and to survey the impact of quality and quantity of different coagulants on wastewater in this factory.Materials and Methods: It was a two-phase study. First, we have determined the quality and quantity of the wastewater, then, the impact of different coagulants was surveyed. Sampling was achieved on 3 weeks, each time for a total 24-hour period. The following parameters were measured: PH, COD, BOD, Phosphorous, Nitrogen and total solids. For the second phase we have determined the role of ferric sulfate, chlorour ferric, aluminum sulfate and lime on COD removal.Results: Study was carried out on 12 samples. Maximum concentration of COD, BOD and total solids were 10906, 120 and 69562 mg/l, respectively. Chlorour ferric at the concentration of 100 mg/l was revealed to be the most effective coagulants. It has reduced the COD concentration from 7560±117 to 646±95 mg/l.Conclusion: This match factory has a very polluted wastewater. It mainly consists of biologic materials. Chlorour ferric was the most effective coagulant. With respect to the high value of COD, biologic method is not recommended for sewerage. Chemical coagulation is the method of choice.
