Physico-chemical and microbiological characteristics of textile processing effluent from Karnataka Processors Ltd. have been investigated. It has been observed that some of the waste streams are highly alkaline in nature (pH 8.7 to 10.9). Such waste streams also exhibit higher COD levels; 1300 mg/L from mercerization section and 1680 mg/L from desizing section. All the waste water streams possess higher TDS concentration ranging from 2000 to 6000 mg/L. BOD values were in the range of 135 to 900 mg/L, and alkalinity from 200 to 8000 mg/L. Highest possibilities of microbial counts on nutrient agar (NA) and potato dextrose agar (PDA) were observed in the water samples collected from general utilities. Combined waste and wastes from dyeing and desizing sections also indicate the presence of microflora on growth media. However, no microbes were observed in the waste samples from mercerizing and bleaching sections. When the study conducted on quantitative basis, it was observed that microbial count was maximum (2110 × 104 CFU/mL) in the sample plate of general utilities, which was reduced to minimum in the samples from other streams.

Abstract


Physico-chemical and microbiological characteristics of textile processing effluent from Karnataka Processors Ltd. have been investigated. It has been observed that some of the waste streams are highly alkaline in nature (pH 8.7 to 10.9). Such waste streams also exhibit higher COD levels; 1300 mg/L from mercerization section and 1680 mg/L from desizing section. All the waste water streams possess higher TDS concentration ranging from 2000 to 6000 mg/L. BOD values were in the range of 135 to 900 mg/L, and alkalinity from 200 to 8000 mg/L. Highest possibilities of microbial counts on nutrient agar (NA) and potato dextrose agar (PDA) were observed in the water samples collected from general utilities. Combined waste and wastes from dyeing and desizing sections also indicate the presence of microflora on growth media. However, no microbes were observed in the waste samples from mercerizing and bleaching sections. When the study conducted on quantitative basis, it was observed that microbial count was maximum (2110 × 104 CFU/mL) in the sample plate of general utilities, which was reduced to minimum in the samples from other streams.
