Mechanical Fine Screen

  • Type Step Type
  • Material Mild Steel, Stainless Steel
  • Application Water Control or Treatment Equipment
  • Feature Automatic Control, Corrosion Resistant
  • Angle of Inclination 40 degrees

The step screen consists of a series of stationary and mobile steps alternating with each other. As the effluent flows through the step screen, a screening mat develops along the surface of the screen. The mobile steps progressively lift the mat of solids  along the inclination of the screen. On reaching the top of the step screen, the solids are discharged by gravity into a screw conveyor or similar device. The low-inclination angle ensures that a screening mat is retained continuously during the entire operation and prevents the roll down encountered in steeper screens.   A consistent screening mat contributes to a uniform and highsolids capture rate. Step screen is capable of handling flows of up to 23, 775 gpm / 5, 400 m³/hr through a single unit.   Applications: municipal waste water treatment plants, industrial waste water treatment plants such as: paper mill, slaughterhouses, food industry, fish industry, chemical industry.   Advantages: separation of non-biodegradable solids, floating or inorganic substances, self-cleaning screen, low operating costs, available also in stainless steel tank, with nozzles.

Clarifier Tanks

  • Housing Cast Iron Grade FG : 200 in Single Part .
  • Gearbox Our Gearbox is Cycloid and provides more efficient and durable operation
  • Lubrication Our clarifiers have completely oil-immersed Gears for extended gear life.
  • Central Driven Version 5 – 10 Meters
  • Peripheral Drive Versions for 10 – 20 Meters & 20 – 40 Meters Ranges.
  • Gears Flame hardened Cast Iron Spur Gears made with 10 Module teeth and compatible EN 8 Pinion.

We manufacture both varieties: Peripheral and Centrally Driven Clarifiers. Our Yashwant Clarifiers are made from Single Internal Spur Gear with Cyclo Gearbox Drive to reduce power and maintenance requirements. Yashwant Clarifiers are easy to install and provide years of hassle-free and un-interrupted service to our clients. Our design is robust and indigenous, with easily replaceable spares and top-notch after sales and maintenance services.    Our clarifiers have been installed in Industrial and Municipal Sewage Treatment Plants throughout India and up to Tank Diameters as large as 40 Meters. Our Centrally Driven Clarifier has at its heart a1200mm Diameter Spur Gear which provides prolonged service without breakdown and interruptions.   The clarifier tanks can be classified in two groups: Mechanized and Un-mechanized In an un-mechanized clarifier, the bottom of the tank is shaped like a funnel, with a steep slope. The sludge slowly settles towards bottom, and slides down the slope to collect at the lowest point of the funnel-shaped bottom. In a mechanical clarifier, the bottom of the tank has only a gentle slope toward the center. The sludge settles uniformly across the floor of the tank. A set of slowly rotating rubber blades sweep the sludge into a hopper at the center of the tank.   Early torque ratings were based on the Lewis Beam formula, a criteria that considered tooth strength only. In the 1970's, specifications began to appear requiring that spur gear ratings be based upon AGMA standards, at that time AGMA 210 and 220 for spur gearing, and AGMA 440 for worm gearing. AGMA 210 brought durability into the rating equation. Since that time, AGMA 210 and 220 were combined into new standard AGMA 218, and later into ANSI/AGMA 2001. AGMA 440 evolved into ANSI/AGMA 6034. Throughout the evolution of Clarifiers throughout India, our gear drives have consistently evolved incorporating the best design practices and indigenous designs and concepts. Only suppliers such as us who have kept current with, and reacted to, the changing standards can truly state that their gear drives are "Designed in full conformance with required standards."   Technical Specifications: Size Range Yashwant Clarifiers are available for Tank Dimensions Central Driven Version 5 – 10 Meters Peripheral Drive Versions for 10 – 20 Meters & 20 – 40 Meters Ranges.   Types Peripheral and Central driven. -  For Central Driven Clarifiers, Pedestals are provided for mounting of Clarifier unit.   Torque Limiters - We also provide Torque Limiters (Optional Variant) for monitoring the torque requirements of the Clarifiers with alarm facility in case of excessive torque being subjected on the clarifier drive.   Bridges & Structural Their Designing Erection of Bridges have immense important in the working of a clarifier. We understand the vitality of designing and manufacturing bridge to mount our clarifier assembly. The bridge though as light as possible must also be as strong as possible. Hence we pay special attention to designing and manufacturing We have special consultants with expertise from Clarifier Manufacturing and Erection Field to design and analyze the Structural Design Aspects of the Bridges. Our Bridges are manufactured with highest safety standards and safety factors for withstanding high load & stress application at site. The bridges are designed so as to facilitate easy on site assembly and also provide for highest strength and structural stability. We have expertise in manufacturing full and half bridge structures which are easy to assemble , highly cost effective yet comprehensive in strength.

Manual Bar Screen

  • Material Metal
  • Application Water Control or Treatment Equipment
  • Color Silver
  • Feature Corrosion Resistant, High Quality
  • Driven Type Manual

The screen is typically installed in a pumping station or at the inlet of sewage or water treatment plants. The retained solids are then extracted by means of a cable driven manual raking system which lifts the solids outside the channel and discharges into a hopper.   To prevent material too coarse from reaching the travelling band screens, bar screens may be used in two stages where the first screen with wider bar spacing remove bulky solids; a second bar screen with smaller bar spacing then remove debris still coarse enough to clog travelling band screens installed downstream for finer screening.   Filtration at the first stage of sewage water intake system is done by variety of   Bar screens. Bar screens can be categorized according to various properties: Removable Type: Screen can be removed & replaced from Frame. Fixed Type: Screen is fixed to the channel or opening. This cannot be removed. Curved/ Hyperbolic Fine screen Flat Fine Screen Fine Screens- Generally distance between two bars is Medium Screen- Generally distance between two bars is Coarse Screen- Generally distance between two bars is Wedge Type Bar Screen: Easy to clean & lesser maintenance Straight/ Flat type Bar screen Static Screens are known for Low installation and operating cost & High capacity per unit area of screen.
