Abstract
An attempt was made to analyze the water quality o f the effluent from the textile industry. The effluent sample was collected from
Karur, a textile city in Tamilnadu. In this investigation physicochemical parameters such as colour, odour, electrical conductivity
(EC), temperature, total suspended solids (TSS), total dissolved solids (TDS), total solids (TS), pH, total alkalinity, total
hardness, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), chlorides, sulphates,
phosphates, nitrate nitrogen, lead, nickel, zinc, chromium, copper, oil and grease were determined using standard procedures.
The result o f this analysis was compared with the water quality standards o f BIS (Bureau o f Indian Standard). The effluent
sample was dark violet in colour with objectionable odour. It showed high electrical conductivity, high TSS, TDS, TS values,
alkaline pH, high BOD and COD, low DO, high amounts o f chlorides, nitrates, sulphates and also showed the presence o f heavy
metals, oil and grease. It was observed that all the parameters studied exceeded the BIS limits.
