Integrated Sequential Anoxic-Aerobic (ISA) Reactor for Wastewater Treatment

Wastewater treatment is the process of removing contaminants from raw water. The goal is to produce water that follows the standards, to meet the government standards which can be used for the specific purpose of human consumption. Rubber wastewater treatment includes removing of the particles, organic molecules, bacteria, algae, virus and toxic metals. The rubber industry is one of the industries that produce high amounts of the liquid and solid waste. In this research the aerobic-anoxic treatment method will be used to treat rubber wastewater. The two methods combined in one reactor which is Aerobic-Anoxic Sequential Reactor (ISA). It consists of a cylindrical tube with 160 cm height and 6.5cm diameter. The upper part used as anoxic tank where nitrification take place. During nitrification process ammonia (NH4-N) is oxidized to nitrate (NO2-N) and then to nitrate (NO3-N). Nitrate produced in the upper part of the reactor. The effluent from this process is recycled back for oxidation reduction reactions in denitrification process, which convert nitrate to nitric oxide, nitrous oxide, and nitrogen gas
