Waste Water Treatment Plants remove contaminants from waste water and household sewage and make the water fit for various applications. It can easily treat both runoff as well as domestic effluents. The treatment plant uses physical, chemical, biological and tertiary processes to remove physical, chemical and biological contaminants from water.
Waste water is fed into settling tanks
During this time, heavy solids settle down to the bottom of the tank and become thick slurry known as primary sludge
Floating materials are skimmed from the surface of tank
In this process, dissolved oxygen demanding organic substances are removed
The waters is then clarified by separating treated liquid from grown bacterial cells using gravity
The effluent is further treated to remove nitrogen, phosphorus, microbes and fine suspended particles
Equalization Tank (Balancing Tank)
Aeration / Membrane Bio Reactor Tank
This waste treatment plant is widely used in industries and residential areas for treating sewage water.
Effluent Treatment Systems are widely used for recycling of wastewater in industries in order to reduce the demand of water. This type of system uses physical, chemical, biological and membrane processes for treating the effluents before being discharged into the water. The effluent system is provided with all the requisite features that assist in achieving zero-discharge standards laid by statutory authority.
Raw effluent is passed through Screening and Grit chamber for removal of floatable matter and sand, grit, stones
After this, the effluent is passed through Oil & grease trap where floatable oil and grease is removed from raw effluent.
Then the effluent is treated through primary treatment that includes chemical treatment like coagulation, flocculation and neutralization
After primary treatment, the effluent is passed for secondary treatment that comprises of biological treatment for reduction of BOD/COD and solid-liquid separation
Finally the tertiary treatment in which sand and carbon filtration is done for removal of suspended solids and organic material
Slurry Feed Characteristics
Flow rate: 1140m3/hr
Suspended matter: 6000ppm
Temperature: 60-70 degree Celsius
The inlet channel is designed for a surge flow of 1950m3/ hr at the slope of 2% so that water flows at the rate of 1.5m/sec.
Two flash mixers are designed for a flow of 1140m3/ hr with a retention time of 60 sec.
Clariflocculators are combination of both flocculation as well as clarification. With this, the installation of plant becomes economical and faster. All these clariflocculators are best suited for water treatment plant, waste treatment plant and effluent treatment plant. Available as centre driven and end driven models, these clariflocculators consists of concentric circular compartments.
Centre Driven Clariflocculator
End Driven Clariflocculator
Full Bridge Clariflocculator
Half Bridge Clariflocculator
The water is fed into the clariflocculator
Flocculating paddles increases the flocullation of feed solids
In the process heavy particles settle to the bottom
Remaining liquid flows upward in the clarifier zone
Then the clarified liquid is discharged over a peripheral weir into the peripheral launder
The sludge deposited is then routed to the sludge chambers and discharged
Water Pollution Control Systems are installed at almost all types of industries. All the systems used for controlling water pollution are suitable for industrial, domestic and commercial establishments. All these systems carry out high rate clarifier coagulation, precipitation and bio-media clarification of waste water.
Our range of water pollution control systems includes:
Water discharge system
Salt recovery system
Zero discharge system
Industrial water treatment plants
Reverse osmosis water treatment plants
These Water Pollution Control Systems are installed at various residential areas, industries and commercial establishments.
Clarification is the process to remove suspended solids from water which is done by Clarifier. It is the economical and an essential part of effluent treatment plants and other raw water treatment plants. Depending upon the plant, the clarifiers are available in wide varieties of shapes. In large scale wastewater treatment facilities, large circular open-air clarifiers are preferred.
Types of clarifiers:
Solids Contact Clarifiers
The clarifiers operate on the principle of gravity-separation. The separate solids would flow downward and settle on tapered floor.
The untreated oil is forced towards the periphery of the bowl by centrifugal forces
Then the oil is passed up through the disc stack
Actual separation takes place here in the channel formed between two discs
The two forces act on each solid or liquid particle
The particles are pushed upwards with the oil stream towards the centre while the centrifugal force directs it to the periphery
The residual force on denser particles will drive them towards the periphery
While the less dense particles (oil) will be directed towards the centre of the bowl and raise to the outlet connection
We are manufacturing world class Solid Contact Clarifiers that have capacity to act as both an improved flocculation device and high rate chemical precipitator. Here, mixing, internal solids recirculation, gentle flocculation and gravity sedimentation are all combined within single unit. The solid contact clarifiers mix the influent flow with previously settled solids within the draft tube. In this, the gentle mixing within the reaction well promotes agglomeration of floc particles and chemical precipitates. Then, the aggregated solids settle out more quickly in the clarification area. In the solid contact clarifiers, clarified overflow is removed through a radial launder system that draws water from the complete surface area to avoid solids carryover caused by uneven velocity currents.
Features • Low energy mixing for chemical reactions & formation of floc particles • Unique low shear high volume impeller • Gravity sedimentation clarification and enhanced flocculation in one unit • Consumes less chemical input • Low horsepower requirements • Requires less space than conventional flocculation and sedimentation train • Considerable savings in terms of tankage, civil work, and operational costs
