Abstract

Hospitals consume and generate a large volume of hospital wastewaters which is complex in nature as it has a variety of pollutants which need specific treatment before being discharged into the aquatic environment.Hospital wastewater management thus is an integral part of any health care facility.The treatment of any hospital wastewater largely depends on its basic physico-chemical parameters as these tend to interfere with the above.Our study aims to analyse the quality of wastewaters released by the 05 hospitals of the Alwar city and also evaluates the existing wastewater management practices. Methods: The study had two sections: our first section was analytical where samples were analysed for physico-chemical and bacteriological parameters. On the obtained results an analysis of variance at significance 0.05 and parameter correlation matrix was performed. In the second section hospital wastewater management aspects were assessed through a questionnaire for which the respondents were serving staff of the chosen health care facilities. Results: With regards to physico-chemical variables only the pH values were in agreement with the standard limits, rest all parameters were in the higher range with TSS and COD results showing significant variation(p<0.05), for the bacteriological analysis both total coliform and faecal coliform were in higher range and had significant variation (p<0.05) between the hospitals.The hospital wastewater management practices showed a lacuna in the pretreatment and disposal aspects whereas segregation and collection were in accordance with bio medical waste management rules, 1998. Conclusion: The samples of hospital wastewaters were polluted, received no specific treatment and management of wastewaters by the health care facilities was poor.
