The appropriate technology for separating flocculants in dyehouse wastewater depends on the level of pollutants in the water, the availability of space, and economics. If enough space is available and initial construction costs are not prohibitive, the sludge blanket setting tank is suitable for most applications. The advantages of the sludge blanket include economic operation, low maintenance requirements, a high capacity, and an insensitivity to large variations in flow rate. Where space is at a premium, the vertical cross flow filtration method is highly efficient. This method, however, suffers from several maintenance problems and consumes large amounts of power. For low pollutant loadings, the contact. This method requires no settling tank and can be automated, but water is wasted during backwashing.
