The relationship between filterability and some factors which have influence on emulsified cutting fluid quality was described,the filterability change of in-use cutting fluid was monitored with filter test method.

It is concluded that the future turbine oils should have long life with excellent oxidation stability, sludge resistance, filterability, cleanliness, hyd.

It was pointed out that there are various problems during far\|infrared fiber production that ceramic particles perform poor compatibility and dispersity in PET and far\|infrared fibers exhibit low filterability and rheological behavior.

Improvement of membrane filterability of mixed liquor in membrane bioreactor by ozonation;

The relationship between needling density, the depth of needle penetration and the properties of nonwovens, such as basic physical properties, mechanical properties and filtration properties is analyzed thoughout experiment and theory analyses.

The change of filtration properties of stainless steel fiber media after twisting deformation was investigated.

Melt-blown PLA nonwovens which has good filtration property is produced by optimizing process parameters.

s: Nonwoven geotextile can be applied in various engineering with their favorable chemical and physical properties as well as excellent filtration property.

BP neural network model could be used to predict the filtration properties of melt blown nonwoven fabrics, furthermore could be used to determined the manufacturing parameters for given filtration property.
