Thin film track etched membranes, commonly referred to as polycarbonate (PCTE) and polyester (PET) filters, feature a unique pore structure and optical clarity unlike most filters. A complex, two step manufacturing process involving ion bombardment of the film followed by a chemical bath results in this attractive membrane exhibiting a smooth surface interrupted with the appearance of wrinkles, ...
Last month we examined filter selection strategies for maximizing service life in continuous use applications. In this 3rd installment, we will examine the use of prefilters to extend service life. Clarifying liquids with high levels of suspended solids is challenging, especially for applications requiring submicron filtration. In these applications, filter users who experience frustratingly ...
Sterlitech currently offers membrane disc and sheet filters in 10 different polymer types and 4 inorganic filters. 2 of the polymer types are subdivided into 4 subgroups based on surface chemistry alone. ...
The most common filtration grades are 100-200 micron, depending on the flow direction in the membrane capillaries. Disc filters are the most suitable technology as UF treatment, due to the high filtration velocity which reduces footprint and thanks to the efficiency in the recovery of the filtration media during the backflush. Guaranteed ...
In total the compact DEVISE units offer the following advantages and savings: Prefabricated and pre-tested systems, ready to "plug and play"; Low footprint requirements: Limited civil works; Quick installation; Can be moved to a different site if necessary; Modular arrangement; treatment capacity can be readily increased by operating two or more individual modules (compact units) in ...
In order to develop a fast detection method for viable C. parvum oocysts, a 0.2 μm pore size hollow fiber membrane and 0.45 μm pore size disc membrane were used to filter tap water. ...
