It has been observed that invariably higher concentration of chemical like acids,alkalies,hydrosulphide,bleaching chemicals and various auxiliaries are used in textile processing as per manufactures recomandations in order to provide a large margin of safety. From the point of reduction of pollution load this calls for critical study of chemical recipes used for each step.After judicious study,minimun ammount necessary for process should only be used for satisfactory working.This not only helps in reducing the pollution load,but also helps in effecting concidearable economy.Any extra residual chemical even from sweeping etc. entering the drains will have a harmfull efect and make the effuent highly vulnerable.
