In modern years, the wastewater generated from pharmaceutical industry and active pharmaceutical ingredients, solvents, intermediates and raw materials has gained increasing attention. Most of the pharmaceutical industry generally contain high organic load and the treatment is primarily conceded out using two main types of biological methods; aerobic and anaerobic. Traditional wastewater treatment methods, such as activated sludge, are not adequate for the complete removal of active pharmaceutical ingredients. Due to high strength, it is not possible to treat some pharmaceutical wastewater using aerobic biological processes. As a substitute, an anaerobic process is chosen to remove high strength organic matter. As an outcome, complementary treatment methods such as membrane filtration, reverse osmosis and activated carbon are regularly used in conjunction with the traditional methods for treatment of industrial wastewater. In this article we discuss about effluent testing and treatment in pharmaceutical industry. Biological treatment of waste water is commonly the most beneficial method for selecting various toxic compounds for the environment. Antibiotics are the major groups of pharmaceuticals. Amoung all the other pharmaceutical drugs and substances antibiotics are important compounds due to its serious irreversible increase the release to the environment. Validation of water treatment systems is necessary to obtain water with all desired quality attributes. This also provides a framework to establish a total control over the process which monitors safety, efficacy and ultimately, the process outcomes.
