Water Filtering Systems

Water filtration can also be necessary in some industrial processes such as wet sandblast media reclamation.

Water filtering is a very important process. In developed economies, industrial water filtering takes place on very large scales in order to provide populations with sufficient quantities of safe drinking water. That water is also used for other purposes such as dish and clothes washing, both of which purposes require access to a source of water that meets a certain standard of cleanliness. In developing economies, small scale water filtration efforts are also essential to public health and well-being.

Access to clean water is a major source of contention worldwide, which makes effective water filtration technologies very important. There are several different methods of filtering water. Each method offers different advantages, and each method is more appropriate in some circumstances than in others.

Electrodialysis (ED), for instance, uses membranes to desalinate or electrically concentrate solutions by allowing passage of either the positively or negatively charged ions, into which the salt was dissociated, while excluding the passage of ions of opposite charge. The membranes and other active surfaces have a tendency to become fouled or scaled.

Electrodialysis reversal (EDR), on the other hand, deals with this problem by reversing the electrical current and exchanging the fresh product water and the concentrate wastewater streams within the membrane stack many times per hour. This process removes the fouling and scaling constituents from one cycle to the next. Reverse osmosis (RO) is a cost-effective pretreatment for ion-exchange demineralization that unloads 95-99 percent of dissolved salts, TOC and silica from the water supply.

RO is a multi-stage process in which cylindrical pressure vessels house interconnected cellophane-like membrane elements with hole sizes of less than .0002 microns, through which incoming dirty water is forced. Other common water filtering methods include electrodeionization (EDI) and ultrafiltration (UF). Water filtering systems are necessary to purify contaminated or unclean water. Water filtration is common in the wastewater/sewage treatment, food and beverage processing, automotive/trucking, agricultural, pharmaceutical, chemical, mining, and pulp and paper industries.

Water Filtering Systems Water filtering systems remove contaminants from water through the use of a thin obstruction, various chemicals or other methods. While most commonly used for the purification of drinking water, filtered water is also used for other various purposes, such as in aquariums, irrigation and in swimming pools.
