Our Products
Vishuddhi has a tradition of manufacturing and supplying the industrys highest quality and most reliable clarifier mechanisms from basic bridge or pipe supported mechanism to those with the most complex and demanding special requirements. Vishuddhi mechanism are driven by high torque designed drive units that have corrosion resistant and precision ratings superior to any drive on the market, and exceed the industrys highest standards.
Vishuddhis versatile clarifiers with central and peripheral drive are specially designed and developed for a vast range of applications. High toque gear drive with overload protection facility provided for minimal maintenance. Vishuddhi offers a wide range of clarifiers / clariflocculators ranging from 5 to 50 meter diameter tanks.
The Lamella clarifier name is derived from the laminar flow regime that is maintained between the two layers of the media.
The EMC Series Slant Plate Clarifiers are designed for efficient removal of readily setteable solids. In this slant plate clarifiers, setting take place on the plate surface and the effective setting area is the plates surface area.
The EMC's compact, small footprint design requires less installation space than conventional or tube type clarifiers. The EMC design incorporates slanted plate setting surfaces pitched at a 55 angle from the horizontal with uniform plate spacing. Due to plate angle the solids slide down the plates into the solids hopper below the plate pack. The simple, inexpensive design, combined with no moving parts or sludge auger makes the EMC easy to install, operate and maintain.
Features
Dissolved Air Flotation (DAF) is a clarification process for the separation of solids, grease and oils. It works by producing a stream of micro-fine air bubbles that attach to solids and float them to the surface where they can be removed by a surface scraping mechanism.
DAF is ideally suited to particles and flocs that are slow settling, neutral density or buoyant. This is particularly relevant to food and other industries where solids are light and voluminous and so not suited to settling. DAF also takes up considerably less space than settling methods, generally less than 25% equivalent surface area needed.
Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, paper mills, general water treatment and similar industrial facilities. A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores.
Mechanism of Dissolved Air Flotation:Solid particles in liquid suspension become attached to microscopic air bubbles. Waste flow or a portion of clarified effluent is pressurized to 3.4 4.8 bar in the presence of sufficient air to approach saturation. When pressurized air-liquid mixture is released to atmospheric pressure, minute air bubbles are released from the solution.Agglomerate rise to the surface to join other particles and form a blanket that can be removed mechanically. Flotation is used primarily to remove light suspended solids.
Further air-solid mixture is skimmed off from the surface. Clarified liquid is removed from the bottom. A portion of the effluent is recycled back to the pressure chamber.
