Exclusive treatment by one of these three methods has ,proved, to be insufficient in removing color and other effluent from textile industry ,wastewater,. While some dyes are difficult to biodegrade few, particularly the hydrolyzed reactive and certain ,acidic, dyes are not readily absorbed by active sludge; hence they escape treatment.

The acidity and alkalinity of the industrial effluents can vary from pH 1.0 to pH 12.0. Therefore, another problem often experienced in natural water systems, is the change in the pH of the water. Natural waters now vary in pH from 4.0 to about 9.5. Some of the acidification of the waters occurs naturally.

The wastewater was acidic (pH 3.3-6.3) and thus soda ash was also added to adjust the influent pH to neutral. The wastewater emanating from the balancing tank was then fed into the bottom of the UASB reactor and the effluent discharged from the top together with the gas.
