Treatment of pharmaceutical industry’s waste water using low cost adsorbents.

Chemical Engineering

The pharmaceutical companies plays a leading role in the sustainment of human life. A large amount of waste effluents have been generated having diclofenac, salicylic acid, ibuprofen and acetaminophen contaminants. Because of increasing environment awareness, it is necessary to remove the pollutants from waste water stream. Adsorption is one such method, but the problem faced is regeneration / recovery of adsorbent. An alternative to this is to make use of low cost adsorbent. This work here focuses on low cost adsorbent aiming to decrease pollutants being discharged into water bodies. The researchers have found various cheap adsorbents for the treatment of the effluents changing the parameters like pH, adsorbent dosage, temperature, pressure, etc. There are very few research carried out on the pharmaceutical industry, so we have been focusing on treatment of the waste water collected from the pharmaceutical industry which manufactures intermediate chemicals.
