Sieve Bend Screen  is one of the fine screen equipment used in treatment plants.  It is physical treatment equipment operating by gravity, without the need for electrical energy. Instead of domestic wastewater treatment plants, it substantially prevents organic or inorganic contaminants originating from industrial wastewater treatment plants from entering into treatment plants and causing possible pump, equipment, and lifting/elevation malfunctions. It is especially used in wastewater treatment plants of recycling, food, textile, and paper & pulp industries. Key Benefits of  Sieve Bend Screen 1.Easy separation of solids from the slurry 2.Maximum efficiency 3.Lengthened screen panel life Our Sieve Bend screens have many sizes to serve all your needs regardless of the size of your applications. Quality-crafted Sieve Bends screens, suitable for a range of screening media. Our Sieve Bend range has a number of industry-leading features and is designed in many different siz...

Be it any industry, the process of  filtration  is an essential prerequisite. The same goes true for the oil & gas industry as well. Oil is found deep inside the earth’s crust, hidden in the layered structures. Naturally, it is crude or raw and remains mixed with impurities. Hence, the filtration of oil to purify it and get it rid of the impurities becomes a necessity.  Generally, the  filtration and separation of oil gas  is divided into three stages 1.Upstream The upstream part of the oil and gas business is comprised of production facilities. These facilities are where hydrocarbons are first recovered in the process. 2.Midstream Transportation of produced fluids, gas processing, and LNG production is what comprises the midstream segment. Separation of oil, gas and water and the removal of solid contaminants is essential prior to pipeline transportation. 3.Downstream Oil and gas refining process rely on the purity of feed streams for efficient process reac...

Filtration is the creepy uncle of the aquarium world. It may not be popular, but if your aquarium is facing an emergency, you will be glad you have it. So, let’s take a closer look how it can be used to benefit your aquarium. Chemical aquarium filtration  is needed because a number of dissolved, invisible compounds accumulate in aquarium water and they can't be removed by mechanical filtration. These compounds are not toxic to the fish but can inhibit their growth and cause chronic, low-level stress that eventually leads to disease. Most of these compounds are dissolved organic substances produced by natural biological decay. Chemical filtration removes many, but not all, of these compounds. However, some substances that affect the growth of the fish can only be removed by making partial water changes on a regular basis. If this isn't done, the fish will never grow to normal adult size. This stunted growth will result in fish that never achieve the beauty of mature fish, and it...

DSM sieve bends screen  is easy to penetrate, having good wear-resisting and corrosion resistance. With Trapezoidal cross-section, even gap, stable welding quality, large opening area, long lifetime, high strength and high load capacity, it can be made into various shapes. The dimensions, wire diameter, slot, and frame structure can be customized. Application of  DSM sieve bends screens They are used in industries such as Sugar, Coal Mining & Quarrying, Mineral Processing, Cement, and Industrial & Urban Effluent Treatment, etc. Sieve bend screens are also used as a pre-filter in urban & industrial waste treatment plants to improve the performance of the clarifier by dramatically reducing the load. Widely used for fiber removal in the Starch industry. Features of DSM sieve bend screens Low Headroom - only 1.1 meters (44") tall for the 900 mm arc length unit. Energy Efficient - operates with no moving parts and with no energy input. Space Efficient - treats up t...

Wedge wire rotating drum screen built for heavy pretreatment applications such as draining, mud thickening, and sandy or industrial wastewater treatment. This product is highly recommended for membrane bioreactor (MBR) treatment plants. OPERATING MODE Solids-laden effluent discharges from the head box and overflows a weir, flooding the top of the cylinder's exterior along its entire length. As it rotates, liquid from the effluent drains through slotted apertures in the screen onto an internal baffle that concentrates the flow against the interior side of the cylinder at its lowest point, dislodging any solids trapped in apertures, even when handling oily, greasy, fibrous or resinous matter. Design wedge wire rotating drum screen can be customized based on specifications and/or structural constraints. MATERIALS 304 or 316 stainless steel T.I.G. welding techniques These rotary drum screen are filters used for gravity filtration. They are suited whenwater levels variations are low. Ac...
