Different Types Of Industrial Water Filtration Systems
An industrial water filtration device primarily filters water for municipal or industrial treatment purposes for safe disposal or safer use. Industrial water filtration is essential to lessen the quantity of pollutants in municipal sewage water. These pollutants may contain chemicals that can be harmful or even deadly to industrial workers and the public at large. In particular, industrial effluent, industrial wastewater and industrial wastewaters contain heavy metals, toxic chemicals and other substances that may prove harmful or even fatal to people who come in contact with it.
The most common filter used by industrial water filtration systems involves the use of reverse osmosis. This method involves passing water through a semi-permeable membrane called an ion exchange membrane. The water ions are exchanged with the ions of other chemicals and particles in the water. This method has been found to be quite effective in reducing heavy metals and chemicals in treated effluent. However, the concentration level of contaminants in treated effluent is low as most of them are bound to the small pores of the ion exchange membrane and are unable to be removed through ion exchange.
To increase the efficiency of industrial water filtration systems, devices with multiple beds and cartridges are used. By using more than one cartridge, larger particles that were not dissolved in the membrane can be filtered out. This method can ensure that larger particles, those with a larger surface area and smaller molecules are filtered out, from the effluent.
Some industrial water filtration systems combine activated carbon and sand in the bed of the unit. This allows for the selective removal of large particulates and microorganisms. The unit also contains reagent that helps in the separation and absorption of the large particles.
Another industrial water filtration systems that is gaining popularity among industries is the sub micron filter. Sub micron filters are useful in removing very small contaminants and are ideal for use in applications where tap water has a lower quality. They do not contain chlorine or chloramine which are harmful to the health when used in household appliances. They also remove a wide range of organic compounds such as arsenic, benzene, asbestos, lindane and vinyl chloride.
Other options available for industrial water filtration systems are reverse osmosis and ultraviolet light. Ion exchange is preferred because it does not waste any water. But both methods have their drawbacks. Electrolysis is considered the best disinfection method available for use in residential and commercial applications.
