17. Treatment scheme:-

18. The invert level of the last manhole is 4.5 mt below G.L. The treatment scheme has to be designed for an average flow of 21 cum per hour. The design criteria and scheme are elaborated below :

TREATMENT SCHEME:

TREATMENT CONCEPTThe sequencing batch reactor (SBR) process is a cyclic activated sludge treatment process. Multiple reactors are provided to treat the wastewater in batches. Sequencing batch reactors will be and operated to oxidize the carbonaceous BOD, nitrify the ammonia, and denitrify to reduce the total nitrogen to a level that meets the permit limits. All treatment processes including equalization, aeration, denitrification, and sedimentation, and decanting occur in the SBRs eliminating the need for separate clarification and return activated sludge systems.

The typical SBR treatment sequence for nitrification-denitrification systems is as follows:

1. The reactor is allowed to fill with raw wastewater. The filling phase is often divided into stages that include aeration to reduce BOD and to nitrify ammonia and then mixing without aeration to promote denitrification (removal of nitrogen).

2. A reaction phase is generally provided to promote additional treatment.3. A settling or quiescent phase then follows to allow the biological solids to settle.4. A decanting phase is provided to draw off the clarified effluent from the upper portion of the reactor. 5. Often a small idle phase is provided to allow time for miscellaneous operations that may need to occur to

keep the reactors in sequence.

Wasting of the biological solids that are produced by converting BOD to bacteria needs to occur periodically to maintain the design mixed liquor concentration and sludge age. Wasting can occur at anytime in the process sequence. Frequently, wasting is performed following the decant phase when the sludge concentration is highest.

The SBRs will be equipped with diffused aeration, and decanting facilities. The discharge from SBR systems is higher than the inflow because the same volume of water that entered the SBR is discharged over a shorter time period. The treated water from SBR is pumped through the Pressure Filter and Activated carbon column for removal of suspended solids, final polishing and removal of any traces of colour. The effluent is then passed through the UV system to disinfect the treated sewage. The treated sewage can be used for horticulture or in tolites for flushing purposes. Excess sludge from the SBR tank is pumped out periodically automatically to the Filter Press for dewatering and drying during decanting phase
