Sewage Treatment Plants

Sewage Treatment Plants

Introduction

Sewage Treatment Plants are installed and commissioned at various industries for treating waste before discharging them into water bodies. The plant receives the waste from domestic, commercial and industrial sources and removes the harmful materials from the sewage that damage water quality.

We offer following equipments :

    Clarifier.
 
    Clariflocculators.
 
    Effluent Treatment Systems.
 
    Water Pollution Control Systems.
 
    Waste Treatment Plants.

Working Principle :

    Preliminary Treatment: Removal of coarse solids and other large materials found in raw wastewater.
 
    Primary Treatment: Removal of settle-able organic and inorganic solids by sedimentation, and the removal of float-able materials by skimming.
 
    Secondary Treatment: Removal of residual organics and suspended solids

Application :

    All these sewage treatment plants are used for treating sewage and effluents coming out from commercial establishments, residential areas and industries.

Clarifier

Product Description

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. 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.
 
    Secondary Clarifiers.
 
    Primary Clarifiers.

Working :

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

Technical specifications :

    Rotational speeds: 7,000 to 9,000 rpm
 
    Number of discs: up to 150
 
    Separation distance between Discs: 0.5-0.6 mm
 

Application areas :

All these clarifiers are widely used in almost all types of water treatment plants.

Clariflocculators

Product Description

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.


Types available :

    Centre Driven Clariflocculator.
 
    End Driven Clariflocculator.
 
    Full Bridge Clariflocculator.
 
    Half Bridge Clariflocculator.

Working :

    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

Technical specifications :

    Diameter: 4M to maximum upto 70M
 
    Bridge width varies from 0.75M to 1.5M
 
    Number of flocculators: 1 to 4
 

Application areas :

    Municipal water treatment plants
 
    Primary Treatment in ETP
 
    Heavy Metal Removal

Effluent Treatment Systems

Product Description

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.


Working :

    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

Technical specifications :

Slurry Feed Characteristics

    Flow rate: 1140m3/hr
 
    Suspended matter: 6000ppm
 
    pH: 45.-6.5
 
    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.
 
    Capacity of each sludge tank: 224m3

Application areas :

    Paint shop
 
    Diaries
 
    Paper mills
 
    Oil refineries
 
    Leather industry
 
    Glass factories
 
    Chemical
 
    Processing industries

Water Pollution Control Systems

Product Description

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:





Specifications :

    Recycle rate: 50%
 
    Water-out conductivity: 3-8

Working :

The waste water is fed into the water pollution control system. Depending upon the level of impurities in the water, the systems chooses the best possible process for treating waste water with low level of rejection. Various biological and chemical treatments are performed on waste water to filter out impurities and dissolved substances from the water.
