A simple mathematical model of wool scouring

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...

Treatment 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...

Some 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...

Numerical Analysis of a Simple Mathematical Model to Design Bioremediation System in Rhizosphere

A Simple Mathematical Model for Batesian Mimicry

A simple mathematical model is presented for Batesian mimicry, which occurs when a harmless species (mimic) is morphologically similar to another species (model) that is noxious or distasteful to predators, thus gaining a measure of protection. Although mathematical models for species interaction, such as predator-prey or competition, are well known, there is no similar literature on mimicry. T...
