- Abstract
Since discharge limits are becoming stricter for industrial wastes, textile manufacturers are searching for efficient and economical methods of pollution reduction. This is typical of the situation facing the textile industry, especially in the area of color pollution emitted into the earth's waterways. Ozone treatment to remove color from wastewater could be a solution to the problem of color pollution. Color removal is achieved to a remarkable degree using ozone. All of the classes of dyes used in the textile industry are removed from wastewater to a certain extent, some poorly and others almost completely. Ozone also can aid in removing some other pollutants like surfactants and carriers that are commonly found in textile wet processing waste waters. The processing of waste at its source is a new approach to waste treatment. Color removal Is a prime example of the advantages of this method. Color removal Immediately following the dyeing process increases the efficiency and the economics of ozonation and could become the ideal treatment method of the twenty-first century.
