Sewage Treatment

We create a wide variety of Water Clarifier, which are very useful for Water Treatment applications. Clarification is the process to remove suspended solids from water. It is the economical and an essential part of effluent treatment plants and other raw water treatment plants. Clarification is the method used to remove suspended matter from surface water and Industrial wastewater. In essence, it makes "turbid" water "clear," Clarification also reduces iron, manganese, organic material, oil and color. It can be configured to remove hardness. It is the first step in surface water treatment, because the processes that follow normally require clear and colorless influent water. For the same reasons, clarification is often the last step before discharge of wastewater to a receiving stream. Clarification uses chemical addition and the sedimentation process to remove suspended matter from water, as discussed below.

In the next step of clarification, the small floc (microfloc) is allowed to grow into larger floc, called macrofloc or agglomerated floc. This process, called flocculation, flocculation is accomplished by gently stirring the coagulated water to assure contact between microfloc particles and polymer. The polymer enhances agglomerated floc formation. As the agglomerated floc continues to grow, it becomes denser and heavier, allowing it to settle. Our firm is specializes in manufacturing, exporting and supplying an excellent quality Flocculator. Offered product is manufactured with the usage of quality approved raw material and cutting-edge technology under the supervision of our deft professionals in tune with industry quality norms.

The final step of the clarification process is sedimentation. In this step, agglomerated floc settles out to form sludge and the sludge is transported to the sludge concentration chamber by the scraper. The sludge thickening pickets concentrate the sludge. The sludge is discharged to waste in a process called clarifier blow down. Above the sludge, clarified water is collected in the outlet launder and flows forward for use or further treatment.

Ploy Dosing System Alum Dosing System

The first step of the clarification process is coagulation. Particles in water have a naturally occurring negative charge. This causes them to repel each other and stay in suspension. When this charge is destabilized, the particles no longer repel one another, and can come together in closer proximity. A chemical salt, called a coagulant, is mixed with the inlet water to destabilize the charge. Some common coagulants are aluminum sulfate (alum), ferric sulfate and ferric chloride. The coagulants provide a positive charge, in the form of metallic cations that destabilize the natural negative charge of the particles. The metallic cations combine with hydroxide in the water to form a metallic hydroxide that is an insoluble compound. The destabilized particles and metal hydroxide precipitates agglomerate into small, visible particles called floc. Color, organic matter and colloids, including colloidal silica, are removed by becoming bound up in the floc.

Technology: Up flow anaerobic sludge blanket Reactor

Up flow anaerobic sludge blanket technology also known as UASB reactor is a form of anaerobic digester which used in wastewater treatment. UASB reactor is a methane-producing digester, which uses an anaerobic process and forming a blanket of granular sludge and is processed by the anaerobic microorganisms. UASB reactor is based on the so-called three-phase separator, which enables the reactor to separate gas, water and sludge mixtures under high turbulence conditions. The wastewater enters the reactor through a well designed distribution system and is distributed equally over the bottom of the reactor. This favours the formation of granules and well settling flocs. Subsequently, the wastewater rises in an up flow mode through an expanded bed of anaerobic active methanogenic sludge and leaves the reactor at the top through a gas/collection device that separates the mixed liquor into clarified wastewater, gas and sludge. This "three phase separator" is of the cross flow type and is also equipped with parallel plates. Both these characteristics result in a significant improvement of the sludge separation efficiency. In this way, much more sludge is kept into the reactor, which enhances the overall efficiency and stability of the system. Anaerobic excess sludge can be withdrawn from the bottom of the UASB reactor.

Technology: Rotating biological contactors

A rotating biological contactor or RBC is a biological treatment process used in the treatment of wastewater following primary treatment. The primary treatment process removes the grit and other solids through a screening process followed by a period of settlement. The RBC process involves allowing the wastewater to come in contact with a biological medium in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the waste water. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes place.

Technology: Fluidized Aerobic Bio-Reactor

Fluidized Aerobic Bio-Reactor (FAB) consists of a tank filled with specially developed media. These media are made of special material of suitable density, that can be fluidized using an aeration device through diffusers. A bio-film develops on the media, which move along the effluent in the reactor. The movement within the reactor is generated by providing aeration with help of diffusers placed at the bottom of the reactor. This thin film on the media enables the bacteria to act upon the bio-degradable matter in the effluent and reduce BOD/COD content in presence of oxygen from the air used for fluidization.

Ultra filtration membrane filter micro-organisms including their floating dead bodies, cysts and spores from your drinking water by physically filtering them out through a membrane. Ultra filtration membrane is full proof because water passes through a membrane whose pore size is so small that no bacteria or virus can pass through it. Till Ultra filtration membrane gives water, the water is 100% pure and safe. Ultra filtration membrane works on the same principle used by nature to absorb purified water from dirty subsoil water eg. Coconut water. Hence water purified by Ultra filtration membrane tastes natural. There is no operating cost of Ultra filtration membrane as it does not consume electricity but works on overhead tank pressure.
