Physico-Chemical Treatment Of Wool Scouring Effluent
نویسنده
چکیده
The proposed procedure to produce low polluting effluent consists of a combination of coagulation-flocculation and membrane separation process. The main role of the coagulation-flocculation process is the simultaneous enhancement of removal efficiency and increase the permeate flux by minimizing the membrane fouling. Membrane fouling has a significant impact on the cost, design, and operation of membrane technology. Experiments with wool scouring effluent were performed to find optimum conditions and to ensure the feasibility of the process. The optimum operating conditions for the coagulation-flocculation process were pH = 4 and 500 mg/L in ferric chloride. The high-quality permeate stream obtained, with 0.3 kDa polymeric membrane, allows the recycling of 90% of the water to the wool scouring process.

Wool scouring sludge is the solid waste product of anaerobic treatment of wool scouring effluent. It has a high wool grease content (1316% of the dry weight, 45 -55% of the organic matter), resulting in a low melting point (approx. 45°C). The low melting point, the putty-like physical properties and the odourous. unstable nature of the sludge makes it unsuitable for land application in its raw ...

The choice of management practices for the treatment of piggery effluent prior to its disposal to waterways or land is governed by the desire to simultaneously minimise the cost of treatment whilst minimising pollution of the environment. Laboratory experiments were conducted to compare the removal of total and total filterable phosphorus (P) (<0.45 microm) from ortho-phosphate solutions or pig...
