Identifying The Benefits of Ultrafiltration When Used with a Reverse Osmosis Water Filtration System
Toronto, Ontario (PRWEB) April 22, 2014 -- The shale gas revolution that has led a transition from coal to natural gas in industries using petrochemicals. These industrial plants require high-purity water for steam generation and other unit operations. To compound this issue, personnel are facing increasingly tighter guidelines on wastewater discharge quality and quantity.
Ultrafiltration in combination with a reverse osmosis water filtration system have emerged as core components of wastewater treatment systems. Because of their less labor-intensive and less chemical-intensive nature, these technologies have been very attractive for these industries.
Reverse osmosis has become the primary demineralization process for many makeup systems as well though reliable operation requires a knowledge of the process. Its name implies the opposite of osmosis – osmosis being where two solutions separated by a water-permeable membrane to induce a transfer from a less concentrated solution to a more concentrated solution. The pressure in reverse osmosis is applied to the inlet stream to force water through the membrane thus leaving a more concentrated solution behind – the reject.
A unit designed to produce reverse osmosis is often seen as merely a high pressure pump, some pressure vessels, and pipe though the process is significantly more complicated.
A simple two-stage single-pass reverse osmosis unit, for instance, feeds water to the leading end of the two lower pressure vessels where a portion passes through the membranes and is collected as permeate. That’s the first step. The remaining portion then passes through another pressure vessel with approximately a 50-percent split between the permeate and reject. The transfer of permeate as the water passes along the membranes increases the solids concentration in the remaining feed.
This process causes scale formation to form on the membrane surface. Treatment methods are employed to properly reducing scaling.
Reverse osmosis was first introduced in the 1950s and has find increasing popularity for its many industrial uses which include but aren’t limited to boiler feed water treatment, pharmaceutical applications, food products and beverages, semiconductor applications, and in metal finishing. The power generation industry has adapted it as a purifying method and in zero-liquid discharge applications. This has increased operating efficiency and energy output by 10 percent and sometimes more. The adoption has meant lower prices for RO units and membrane elements, the reduction of significant downtime, and the near guarantee of continued growth in the use of reverse osmosis technologies in this sector.
Ultrafiltration refers to a scale of separation between microfiltration and nanofiltration. It is used to purify, concentrate, or fractionate macromolecules. It assists in conserving energy with minimal operation and labour costs. Retaining high concentrates minimizes disposal costs for a wide range of industries. It has zero discharge capabilities, the initial setup cost is low, and minimal pretreatment chemicals are required.
