Abstract
The world’s water is found in oceans, seas, lakes, reservoirs, rivers and streams, glaciers and snowcaps in the Polar Regions, in addition to ground water below the land areas. The water locked up in the oceans and seas are too salty and cannot be used directly for human consumption, that is, for domestic, agricultural or industrial purposes. The textile industry consumes a vast quantity of water and generates an equally vast quantity of waste water. This work mainly focused on the treatment of wastewater from the textile knitted fabric dyeing industry. The membrane selection process was theoretically designed using well known design software, like KOCH and ROSA. To design the treatment plant system based on the analytical report and software membrane, reverse osmosis (RO) system was used. To compare the experimental and theoretical (KOCH and ROSA software) values for the characteristics of knitted fabric dyeing effluent, the results revealed that the KOCH software membrane shows more recovery, high TDS reduction, less power consumption and low investment cost than ROSA type membrane in the treatment of effluent from knitted fabric dyeing. Key words: KOCH and ROSA software membrane, knitted fabric dyeing, reverse osmosis, textile effluent, water treatment.
