With the help of our experienced professionals, we have been able to design and develop Effluent Water Treatment Plant in Chennai, Tamil Nadu, India. The offered treatment systems are widely used in most of the factories and are designed to effectively solve the environmental pollution problem created by the waste water of a company.

The effluent treatment plant consisting of following major units:
Equalization tank/neutralization tank
Air blower
Alum dosing system
Lime dosing tank
Primary clarifier tank
Alum dosing tank
Lime dosing system
Aeration tank with diffusers
Polymer dosing tank
Polymer dosing system
Secondary clarifier tank with sludge recycle
Chlorine dosing tank
Sludge drying beds
Chlorine contact tank/clarified water storage tank
Filter feed pump
Reverse osmosis (stage I)
Pressure sand filter
Activated carbon filter
Reverse osmosis (stage II)


Process:

The effluent from all the process involved in the industry is first collected in equalization tank/neutralization tank
The equalization tank is provided with the bar screen to remove the coarse particles from the effluent & thus prevent the blockage/stoppage of the pump
Since the effluent is alkaline in nature, pH correcting agent is added in equalization tank/neutralization tank for neutralizing the effluent with the help of dosing pump. The pH is adjusted to 6.5 -6.8
The neutralized effluent is then pumped with the help of effluent transfer pumps to primary clarifier tank
In primary clarifier, tank-flocculating agents like alum, polymer & lime is added
Flocs settled at the bottom of the primary clarifier tank & are then transfer to the sludge drying bed
Mixed along with degraded effluent is then overflows to the secondary clarifier tank The clarifier unit is provided to arrest the microbial sludge leaving the system, as a particular concentration of the MLSS is to be maintained in the aeration tank
The clear supernatant from primary clarifier tank overflows to the aeration tank for biological treatment. The oxygen required for the bacterial growth is supplied through surface aerators
The sludge settles at the bottom of the clarifier tank & is pumped back with the help of sludge return pumps to the aeration tank to maintain required concentration
Then it is passed through a reverse osmosis unit (Stage I) and the treated water is collected in a common tank
The clarified effluent is then treated with chlorine for the disinfection of microbes & further control of BOD, for this purpose chlorine dosing system is provided
In case of excess sludge in the system, the recycle pumps will be used to drain the sludge, to the sludge drying beds
The clarified effluent is then fed to the pressure sand filter & activated carbon filter with the help of filter feed pump
The reject of stage I is passed through the reverse osmosis unit (stage ii) to reduce the discharge effluent to zero discharge level. The treated water is collected the same collection tank of stage I
