Ultra Filtration - A Cleaner Recycling System

Posted by lilymartin on May 9th, 2017

A membrane is a thin layer of semi permeable material which segregates substances when a driving force is applied across the membrane.

Membrane processes are on an upswing as it is used for eliminating bacteria, microorganisms, particulates, and natural organic material, which can impart color, bizarre taste, and odor to water and react with disinfectants to form disinfection byproducts.As advancements are made in membrane production and module design, capital and operating costs continue to decline.

Ultra Filtration: Membrane Filtration Technology

Ultrafiltration is a cleaner recycling system, effective in the removal of colloids, proteins, bacteria, pyrogens (such as gram-negative bacterial endotoxins), and other organic molecules larger than 0.1 - 0.2 micron in size.Ultrafiltration is a pressure-driven purification process in which water and low molecular weight substances permeate a membrane while particles, colloids, and macromolecules are filtered. The primary removal mechanism is size exclusion. A properly designed UF cartridge allows efficient rising of ionic residue from the cleaning and rapidly returns to optimal resistivity and organic purity.

How Critical Is Fluid Filtration In Any Metalworking Or Metal Forming Process?

Increased demands for high surface finish and close part tolerance create a greater need for manufacturers to purify coolants that are constantly being cycled through precision machinery.Fluid filtration technology achieves extended tool life, improves component quality and reduces maintenance and spare part costs. High productivity and low environmental impact are other reasons to monitor fluid cleanliness.

For this reason, continuous removal of tramp oil extends the life of coolants. When tramp oils combine with other contaminants in coolant they can form a sticky substance that clogs lines and sprays. When they hit the tool, the cooling effect of the coolant is reduced, causing shorter tool life, product staining, inaccurate tolerances, and a smoky atmosphere in the plant. Here are a few reasons why removing tramp oil from machine coolant is necessary:

• The cost of coolant replacement has increased with time.

• The cost of labor associated with coolant replacement has gone up.

• Tolerances have become more critical.

• Employers and employees are more concerned about healthy working conditions and plant environment.

• Disposal of spent coolant has become expensive.

 All of the above-mentioned reasons make it compulsory for a machinery service system to keep the coolant clean. Because this will not only extend its tool life, improve parts finish, eliminate smoke and odor, but also greatly reduce coolant purchase and disposal costs.

The most cost-effective and simple method to combat tramp oil problem is Coolant Process Systems (CPS) which is commonly used by manufacturers in the US.
