Synergic effects occurred when different surfactants were mixed,the mixed solution had lower CMC number and surface tension value,which were lower than that of each surfactant components,and it had better cleaning effect.
The optimum conditions of liquid detergent composition are obtained by employing experimental design and variance analysis in this paper. A mathematical model for the forecasting and condrolling of the mutual correlation between major washing efficiency (detergency performance) and their individual constituents has been established through mathematical regression analysis treatment.
A vertical automatic pressing filter was used for a series of separating, washing and air-drying experiments of 4A zeolite crystallized slurry and qualified slurry. The results showed that, the washing efficiency was not good, so the filter could not be used for washing the crystallized and filtered cake directly.
Adding OP or EL surfactants didn't improve the washing effects. It ismeaningful that the washing liquid may be recycled directly without obvious effect on the washing result, which will reduce not only the use level of fresh water, but also thedischarge level of waste water and, therefore, the cost of operating and waste water treating.
The effective 9m diameter thickener not only could be compared with the ordinary 15m diameter thickener in effectiveness ,but also it occupied small sized area and needed lesser captial cost with nice washing result.
Moreover, the attempt is made to point out analytical methods for the determination of those compounds which impart special qualities to the bath preparations and shampoos besides the primary wanted cleaning effect.

The cleaning effect of ultrasound and its surface activation play an important role for the sonochemical enhancement of reactivity in chemical processes involving solid and liquid phases.
Due to the intracavity spatial cleaning effect, a near diffraction limited signal beam was achieved despite a relatively worse beam quality of the pumping beam.
In order to compensate for the lower washing efficiency at decreased temperatures, enzyme producers have devoted much R>amp;amp;D capacity to screen for new proteolytic enzymes which are more suitable for washing at lower temperatures.
