Ultrafiltration membrane filter osmosis wash track price, buy Titan water
Ultrafiltration membrane filter with a pore size in the range from 0.03 µm to 5 µm.
Ultrafiltration membrane for a filter of a sintered material – a thin tubular or flat metal-ceramic membrane filters, which operate in the nano-, ultra – or microfiltration domains with a pore size in the range from 0.03 µm to 5 µm.
Description:
Ultrafiltration membrane for a filter of a sintered material – a thin tubular or flat metal-ceramic membrane filters, which operate in the nano-, ultra – or microfiltration domains with a pore size in the range from 0.03 µm to 5 µm.
Metal-ceramic membrane is a bilayer membrane, are new material.
The cermet membranes are not brittle and have a high mechanical strength although have a thickness of about 250 µm with a ceramic layer thickness of about 15 microns. The substrate membranes, usually made of stainless steel, a ceramic layer of TiO2, TiO2/Al2O3, ZrO2 or SiO2, or a composite of two or more of these ceramics.
Membrane filter have a flexibility. Technology which allows you to filter elements of any shape (Radus bend – 5 mm), including corrugated.
The membranes are light weight, resistant to abrasive wear, bacteria and corrosive environments.
Membrane for a filter of a sintered material can be easily installed into various modules and housings. They can be welding and brazing.
Used double layer metal-ceramic membranes enable you to create high-performance, durable, compact and inexpensive construction which is capable of either completely replace the cumbersome structures, the maintenance of which requires constant costs, or augment existing sewage treatment plant that will achieve a significant savings on services already operating pollution control equipment. But the main advantage is that membranes are self-cleaning, i.e. the filtration process does not require stopping for regeneration or replacement of the filter element.
Membrane of a sintered material give the devices created with the use of metal-ceramic membranes, three major advantages:
– ability to work in aggressive environments
– high performance at small dimensions of the installations
– semiregenerative in the process apparatus.
Advantages:
The advantages of metal-ceramic membranes over alternative natural, synthetic or organic membranes:
– high performance and efficiency
– the ability to create high-performance, durable, inexpensive, and compact treatment plant designs,
– self-cleaning, i.e. the filtration process does not require stopping for regeneration or replacement of the filter element,
– reduction of fixed costs for cleaning liquids
best abrasion and radiation resistance,
– steam cleaning,
– mechanical cleaning,
– electrochemical cleaning,
– at given pH values of the filtrate and the Z-potential it is possible to vary the type of ceramics with the purpose of increasing the permeate flow,
– operation at high temperatures and pressures
– endurance in the “real” working environment and a wide pH range,
– resistance to bacteria.
