Pharmaceutical industry is developed due to the population growth and human health needs. It leads to increase the manufacture of drugs and consequently they discharged to the environment after complete or partial treatment. It releases the toxic compounds into the environment. The present study aims by acclimatize the pharmaceutical wastewater with secondary sewage sludge in various ratios 1:1, 1:2, 1:3, 1.5:2.5, 2:1 and 3:1 to enhance biological degradation. The batch mode operation is carried out for a period of 90 days. Conclusion is drawn based on the Total solids and Chemical Oxygen Demand (COD) concentration. Of the entire six ratios considered for degradation of pharmaceutical wastewater the 1:3 ratio gives a better result in terms of degradation of Total Solids and Chemical Oxygen Demand.
