Study on Physico-Chemical Parameters of Waste Water Effluents
Keywords:Industrial effluents, physicochemical properties, WHO, Contamination.
Effluents discharged from Industries into water bodies is one of major sources
of environmental pollution. It has deleterious impact on the soil microflora and
aquatic ecosystems. Most favourable habitat for a wide range of
microorganisms is soil. In the present work we have analyzed the effluents
from sugar mills, thermal power and steel industry, and analysis was carried
out for five months after definite intervals of time (Dec. 2018-July 2018). The
microbial flora is not affected by released effluent due to the acceptable BOD
and COD values. Parameters including Colour, temperature, pH, electrical
conductivity, TDS, TSS, BOD, hardness, COD, Chloride, sulphate, Nitrate,
Phosphate, Calcium, Magnesium, Sodium and Potassium ions were noted.
Result shows that effluent was highly acidic (pH 3-4), blackish in nature and
having TS, TDS, BOD and COD within permissible limit. The various parameters
present in effluents have been compared with the prescribed WHO standards.
Samples are found to have acceptable values of TS and TDS; chemical
parameters have lower values than the limits prescribed by WHO. Care should
be taken while discharging such effluents in order to avoid contamination of
soil and ground water nearby industry.
