Adoption of Finer Screens Greatly Reduces Pollution in the Headwork’s Area/Industries


An industrial floor is a space that is surrounded with various manufacturing processes and at the same time, similar operations take place the whole day and night. This uninterrupted operation produces chemicals, minute airborne particles, dust and various other allergens inside the industrial space. As a result, the surplus airborne particles need to be kept in check so that it doesn’t release and damage the external environment and this is possible through filtration.

The purpose of industrial filtration is to constantly filter out the surplus wastes with the help of heavy duty filter channels as well as netting them inside a filter bag. Industrial gases, raw materials and chemicals used in the industry must be filtered from surplus impurities to enhance the quality of the products that would be manufactured subsequently. Therefore, industrial filtration is a crucial part of every industrial floor. According to an ongoing study by Future Market Insights, increased adoption of filtration systems in cement production and pharmaceuticals industries can drive the growth of global industrial filtration market. There has been development of various filters, amongst which, finer screens have been useful in WWTP.

Finer screen Used for Filtration in Wastewater Treatment Plant

Eliminating hair, plastics, rags, wipes and various other tough materials at a WWTP is essential. But, a lot can pass through as well as bind the equipment which can cause high costs for maintenance. According to a recent news, a company has developed 2.0mm screen which can help in filtration or eliminate downstream matting.

The screen has a non-clogging design due to which, Or-Tec’s Blue Whale unit could be used for screening municipal, food processing and industrial wastewater with high FOG (fats, oils, and grease levels). These high absorption FOG wastes are exceptionally tricky to screen as well as bind most screens. By continuing to be clog free and open, the screen can function in FOG wastes with 1 mm openings, safeguarding valves and pumps by removing the impurities.

The mechanical bar screen which has 1-5 mm opening is appropriate for the headworks of both industrial and municipal wastewater treatment plants. It consists of around 1,500 units in operation together with 20 in the military bases of the U.S. in South Korea. The manufacturing of screens are done in an ISO 14001 environmental standards and ISO 9001 US manufacturing factory.

Working of Finer Screen

The screen face is formed by using similar order of wedge-sectioned bars with uniform spaces. The water streams through the openings in the middle of the screen bars although the solids are bagged on the screen bar’s upstream side. There are travelling rakes that lift up the bagged solids to the top of the screen. Also, the rakes have penetrating teeth that clean the openings in the middle of the bards fully. These screenings are cleared by a scraper machine to a container for removal.

This method is mechanically repeatable and reliable as the whole rake moves in neatly and continues time-after-time. To maintain the cleanliness of the screen openings, no wash water is required and therefore the screen is environmentally effective. Additionally, vertical screen can also be installed in pumping stations and wet wells to protect pumps.

Therefore, the concept of filtration in industries is very essential for business, customers as well as environmental satisfaction. Provision of world-class quality products can help in work-efficiency as well as in the growth of business as well as customer satisfaction.
