Reduction of Ammonia and Turbidity in Wastewater of Pharmaceutical Industry

Bharat Janaji Dighe, Dr. P. R Patil, Dr. Maheshwari Mishra

Abstract: Pharmaceutical industry is one of the major industries causing water pollution. An Attempt has been made in the present project to reduce the ammonia and Turbidity WWTP for Pharmaceutical industry. Different combinations of dosages of ferric alum and non-ferric alum with cationic and anionic polyelectrolyte of were used at Primary clarifier. It was found that there is substantial reduction in turbidity using 3 ppm non ferric alum and 0.35 ppm cationic polyelectrolyte dose. One more additional dose is applied at secondary clarifier of Non ferric Alum & Cationic Polyelectrolyte which effective. After sedimentation, Effluent passed through Sand and Carbon filter and Turbidity reduced from 86.5 NTU to 3.5 NTU. A new concept of ammonia removal from waste water solution by physical method such as, aeration, oxidation by sodium hypochlorite adsorption by carbon followed by ion exchanger zeolite was study in this work. In the first mode aeration was given to waste water sample and dissolved oxygen was increased at aeration stage. In the second mode absorbed ammonia removed by oxidation by sodium hypochlorite and adsorption by granular activated carbon. In the third mode zeolite was used for zeolite was used for removal of ammonia. Ion exchange is more competitive than the other methods because of its relative simplicity and its economy in application & operation. The Turbidity and Ammonia removal efficiency of WWTP were 96 %, and 99 % respectively
