Decanter Centrifuge

DECANTER CENTRIFUGE is used in ETP/STP for dewatering of sludge.

A centrifuge decanter; consists of a solid cylindirical bowl rotating at high speed, a scroll rotating at the same axis with a slightly different speed, a drive group adjusting the speed difference and the body which carries all the rotating elements. Liquid and suspended solids ( effluent ) are fed along the centre line to a distribution room within the bowl and then accelerated into the bowl by centrifugal force through the feeding point. This centrifugal force then causes the suspended solids to settle and accumulate at the bowl wall. Sludge cake is discharged by scroll from the conical part meanwhile clarified liquid flows back along the bowl and is discharged through the cylindirical end of the bowl by plates which can adjust the level of clarified liquid. Centrifuge decanters are applied for separation of liquid mixtures, separation of solid-liquid mixtures, dewatering, thickening, classification of solid-liquid mixtures and extraction of components.

Features

Screw Filter Press/ Multidisc Screw Press

SCREW PRESS is used in ETP/STP for dewatering of sludge.

The CCP Screw Press is a unique product That offers many advantages over current sludge management practices. The key to the process is the “dewatering drum.” This drum can achieve both thickening and pressing (dewatering) of the sludge in a single, compact operation. Thus the CCP Screw Press can take sludge as dilute as 0.2% to 5% solids directly from a treatment process, such as bottom of clarifier, and produce a cake of over 20 to 35% solids. depend on sludge characteristic. Separate thickening, storage, and conditioning processes are eliminated. In addition, it eliminate operators, continuous use of wash water, and high power consumption.

Features

Sludge Dryer/Paddle Dryer

PADDLE DRYER is used in ETP/STP/MUNICIPAL/INDUSTRIAL for of sludge drying.

The twin shaft design of the CCP paddle dryer ensure a perfect mixing in a radial direction of the shaft where as the transportation of the product through machine is achieved by gravity which results from an inclination of the machine due to its very narrow particles residence time distribution, the CCP paddle dryer is often used as a continues reactor where heat treatment can be combined with a time –depending reaction in a fully continues process The machine has a heated through, containing rotating heated paddle shaft. Specially shaped paddle are designed for maximum heat transfer. This result in an excellent control of the temperature of the product and enable a uniform product quality at the outlet side the product moves out of the machine via an adjustable overflow weir.

Dissolved Air Flotation Unit/ AiroDAF Clarifier

Airo-Dissolved air flotation (AiroDAF) is water treatment equipment that clarifies wastewater (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, dairy industry, automobile industry, food industry, paper mills, general water treatment and similar industrial facilities. A very similar process known as induced gas flotation is also used for wastewater treatment.

Process Description :-

The feed water to the AiroDAF float tank is often (but not always) dosed with a coagulant to coagulate the colloidal particles and/or a flocculants to conglomerate the particles into bigger clusters.A portion of the clarified effluent water leaving the Airo-DAF tank is pumped into a small pressure vessel (called the Air Saturation Vessel) into which compressed air is also introduced. This results in saturating the pressurized effluent water with air. The air-saturated water stream is recycled to the inlet of the float tank and flows through a pressure reduction valve just as it enters the inlet of the float tank, which results in the air being released in the form of tiny bubbles. Bubbles form at nucleation sites on the surface of the suspended particles, adhering to the particles. As more bubbles form, the lift from the bubbles eventually overcomes the force of gravity. This causes the suspended matter to float to the surface where it forms a froth layer which is then removed by a skimmer. The froth-free water exits the float tank as the clarified effluent from the DAF unit.

Oil Water Separator

[Corrugated Plate Interceptors (CPI)/ Tilted Plate Interceptors (TPI)]

Corrugated Plate Interceptors (CPI) works on the principle of Stroke’s law and has capacity of removal of free oil upto 90%. CPI allows the effluent to pass through a plate pack which decreases the turbulence in flow and helps the oil to rise above surface. From the surface it spills in the oil tank which is integrated in the CPI tank. The oil free water eventually comes out from the outlet.

System is designed to remove Oil droplet size of upto 50 micron.

Performance & Technical Features-Benefits

Function

This Cattle Farming Equipment is a solids-liquid separating machine including a screw conveyor. Using both principles of separation,by gravity and by mechanical pressing,the machine is designed to separate the liquid phase from the solid phase in a wide range of substances such as sludge, sewage, manure, solids-liquid mixtures, vegetables, processing waste and others, where the percentage of liquid inside the solid may be considerably different.

The separated solid and liquid phases can be handled in an easier and cheaper way. In some sectors this can even become a source of income.

Operation

The machine receives the material to be separated and conveys it using the screw conveyor inside the separator casing.The liquid phase is separated through the mesh of the cylindrical screen which encloses the screw conveyor. Along its path toward the exit, the material gradually separates progressively the less linked liquid and then the more strongly linked liquid until a plug of almost dry material has formed before the outlet. The plugis continuously expelled through the outlet diaphragm. The machine will automatically find its balance of squeezing force depending on the material. Consequently, it can be used for a wide range of materials without the need for any manual adjustments.
