Physico-Chemical Treatment Of Wool Scouring Effluent
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 o...
متن کاملTreatment of Wool Scouring Waste Using Anaerobic Digestion with and without Chemicals Addition
The aim of this study was to investigate the effectiveness of anaerobic digestion for the treatment of wool scouring wastes. The experiments design comprised three ratios of waste (W) to seed(S) (W:S) of 25:75, 50:50 and 75:25, corresponding to 1.9. 1.7 and 1.5g tCOD/g TS, respectively, with or without chemicals addition. NH4Cl was added to the reactors as a source for nitrogen to achieve C:N:P...
متن کاملTreatment of Wool Scouring Wastewater by Immobilized Chitosan Bio-Membrane
A Chitosan/sucrose/polyurethane composite bio-membrane was prepared by the facile drop coating method. The composite bio-membrane had a porous spongy structure composed of a physical mixing of each component. The water absorbability of the composite bio-membrane increased with increasing chitosan and sucrose contents. Furthermore, the composite bio-membrane with immobilized Aspergillus sojae ex...
متن کاملSome Chemistry of the Wool Industry Scouring and Yarn Production
For many centuries people have exploited the characteristics of the wool fibre. Most know the value of woollen clothing for keeping warm and that it retains this feature even when wet. In the home woollen blankets, carpets and materials all make life more comfortable. Sheepskin rugs are widely used on beds for long term patients to help prevent bed sores, and sheep skin car seat covers are very...
متن کامل2nd National Hazardous & Solid Waste Convention STABILISATION OF WOOL SCOURING SLUDGE BY COMPOSTING
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 ...
