2 Operation Phase 170 Treatment in STP and reuse of treated sewage (available for recycling (153 m3/day), for flushing (69 m3/day) for HVAC (37 m3/day) and gardening (21 m3/day). Excess treated sewage i.e., 26 m3/day during non-monsoon season and 47 m3/day during monsoon season will be discharged to subsurface flow engineered wetland.

A state of the sewage treatment plant with capacity to treat 180 m3 will be constructed to treat waste water. Disinfected effluent meeting irrigation standards will be used for irrigating the landscape and for washing access roads.

Design Basis of Treatment plant – Moving Bed Bio Reactor Preliminary Treatment: The treatment will include the following unit / equipment; o Screen Chamber o Oil & Grease Trap o Raw Sewage Collection Tank o Raw Sewage Transfer pumps All the sewage generated will gravitate through Bar Screen. The Bar screen will take care of any large sized, which will be manually scraped out and collected in drums. Bar screen will comprise of SS plate type screen for removing large sized. From the bar screen it will then pass on to the Oil & Grease Trap for removal of free floating oil. The oil will be scrapped and collected in drums to be disposed as per statutory norms. The sewage will be collected in raw collection tank. Uniform mixing is achieved by providing aeration grid (air sparing) in the collection tank. After completion of mixing, the sewage will be pumped at a uniform rate by sewage transfer pumps to Biological Treatment.

Biological Treatment (Secondary Treatment): This will include the following; o MBBR Bioreactor o Secondary Clarifier o Sludge pump for feeding into biogas plant and for residual sludge treatment

Prepared by ULTRA-TECH Environmental Consultancy and Laboratory Page 42 Proposed Residential cum Commercial Building Project ‘Artech Ferns’, at Ammachiveedu, Kollam West Village, Kollam Taluk, Kollam District, Kerala

The process will be of activated sludge extended aeration biological process of Moving Bed Bio Reactor (MBBR) type. The MBBR process will be an aerobic system having two biological growth process- attached growth and suspended growth. The pretreated sewage from raw sewage collection tank will be pumped into MBBR where support media will provide more surface area for biological growth. Oxygen will be added for biological growth through tubular diffusers.

The sewage will be uniformly pumped to MBBR Reactor to biologically degrade the organic matter. The oxygen required for the bacterial growth will be supplied through Diffuser systems. The system provides better oxygen transfer because of fine bubbles and increased contact with the sewage.

The overflow from MBBR Reactor will gravitate to the Secondary clarifier. The arrested sludge will be pumped back to the Aeration tank to maintain the bacterial concentration in the tank and excess sludge will be sent to the Sludge collection pit and shall be dewatered using a filter press. The filtrate will be taken to the Raw Sewage Collection Tank. The dried sludge can be used as manure for gardening.

Tertiary Treatment: The treatment will include the following unit / equipment; o Filter feed tank o Pressure Sand Filter (PSF) o Activated Carbon Filter (ACF) o UV disinfection system

The clear supernatant from the Secondary clarifier will be collected in a Filter feed tank this tank will be provided with level switch for unmanned operations. The treated sewage will be pumped to PSF followed by ACF. After ACF treated sewage will be passed through UV filtration for disinfection. After UV filtration treated sewage will be collected in Treated Water Tank. Treated sewage from Treated Water Tank can be used for secondary requirement. SLURRY
