SEWAGE TREATMENT PLANT

Type of STP considered - MBBR type 

Capacity of STP - 150 KLDRecovery from STP - 125 KLD

The sewage will be first passed through a Bar Screen Chamber where any extraneous matter

would get trapped.

The sewage would then collected in a Receiving Sump  where the variations in flow and

characteristics are dampened, which otherwise can lead to operational problems and moreover

it allows a constant flow rate downstream. Here the sewage is kept in mixed condition by

means of coarse air bubble diffusion.

Page 6: Housing Report - 1bhk & 3bhk

The equalized sewage is then be pumped to the Moving Bed Bio Reactors (MBBR) where

BOD/COD reduction is achieved by virtue of aerobic microbial activities. The FAB reactors

would be running in series. The oxygen required will be supplied through coarse air bubble

diffusers.

The excess bio-solids formed in the biological process are separated in the downstream Tube

Settler Tank . The clear supernatant will now be sent to the tertiary polishing section.

The tertiary treatment consists of removing the residual organics load, by filtering through

Dual Media Filter, and passing the water through Activated Carbon Filter so that traces of

BOD / COD and excess chlorine are removed.

The tertiary treated water is passed through the Softener and the water can now safely be used

for cooling tower make-up & Irrigation System applications etc.

The biological sludge generated from the FAB, which is settled in the Tube Settler, can be

either drained to the filter press.

The percolated filtrate from the sludge drying beds will be sent back to the Equalization Tank

and the dried cakes can be disposed off suitably.

2.5 EMERGENCY POWER SUPPLY

2.5.1 Emergency power supply is planned with Diesel Generator sets for backup.

2.5.2 Capacity is worked out in the load calculation attached (Anexxure-1). However to come

to proper conclusion abour the sizes of the DG sets, we shall be in agreement with eachother regarding the power back to shops and serviced apartment unit.

2.6 Bulk Diesel Storage:

2.6.1 The Consumption of Diesel needs to be planned only after the consideration of back up

 power to dwelling units are finalised.

2.7 Metring and management sytem :

As the system is Bulk metering , an efficient, rugged and tamper proof energy

Management system is required to the do the billing to the Flat/House owners with aTransparent calculation of the service charges required to maintain the total township.

It is suggested to go with prepaid metering system for all the dwelling units with pre

warning and cut off facilities to regularise the system operations.

Prepaid metering solutions should help in advance payment recovery for power usages by

the client. It should provide single/three phase DG output with max demand control and

auto cut off on exceeding the set demand.

Salient features in general are :-

It is stand alone prepaid system with independent Customer Recharge unit. In this

system, meter is the controller and it controls the overload and zero credits by itself.

Meter has inbuilt cut-off device and intelligent software programming to work

independently as a prepaid system. Meter is recharged by sending a coupon to meter by

CRU. Coupons are generated on the site maintained server loaded with our software.

Meter is also compatible with centralized AMR SYSTEM. In this system, Meter

transmits data to local server through LAN cat 5 networking with use of converters.

The server remains active and logs all the data as sent by meters on set intervals. Meter

can also be recharged through server along with CRU.

Other features includes:-

  Data availability on CRU for user: CRU displays- ID no. KWH, KW, MD, Tariffs rates,

& Balance.

  Alerts for client: - CRU also provides alert message on its screen for low balance,

overload, DG on and power trip.

 

Recharge , Happy recharge & Reset provisions on CRU –   provided for meter recharge &reset by the client

32 1BHK & 3BHK APARTMENTS, PLOT- L & M ,SECTOR - 12 , AT GREATER NOIDA.

  System is very cost effective, smooth, and simple and need very low maintenance.

  System provides complete control over load management, power consumption by the

user and pre payment recovery for use of power.

  Happy hour/emergency recharge is also provided to a max of Rs 100 at a time with each

recharge.  Energy data collected from the meters through AMR LAN connectivity are logged in the

data base of EMS software at local server to generate monthly billing.

  Meter cut off the supply in cases of MD crossed and rejoin it after a minute to check load.

Again it trips the supply if found over load. It repeats the operation three times and then

goes off temporarily. It gets reset through press of reset button on RDU.

  System provides Single phase /three phase supply option on DG operation.

  Common area charges and other charges are included in the monthly bill summary.

  Software provides payment account summery of each client.
