ANNEXURE -1PR NO: CP/7181, dt: 3-5-2010

1.PLANT CAPACITY :

D.M. WATER PLANT : The proposed D.M. WATER PLANT SHALL have

capacity of producing 6000 Liters per hour of Treated Water. The R.O.System in

the DM Water Plant will have 70% recovery with 6000 Liters per Hour ofPermeate Water and 2,600 Liters/Hour of Reject Water. The RO system is

designed considering that our Bore-well will have a TDS of 750ppm (maximum).

The R.O. module proposed is designed as a Single stream, two array (2 stages)

system. The plant operation is by manual operation but with Auto dumping

facility to bypass feed water incase the Residual Chlorine levels are detected high.

THE RO PRODUCT (PERMEATE) WATER FROM THE ABOVE RO

SYSTEM WILL BE PASSED THROUGH A DEGASSIFIER FOLLOWED BYA MIXED BED UNIT TO ATTAIN FINAL OUTPUT WATER QUALITY

WITH TDS LESS THAN 1PPM.

R.D.M. WATER PLANT: The proposed R.D.M. WATER PLANT will havecapacity of producing 4000-4500 Liters per hour of Treated Water. It is propose

to install TWO nos RO Systems with capacities of 3000Ltrs/Hr and 1000 Ltrs/hr

in order to minimize water losses.

A) 3000 LPH RO SYSTEM :

The Reject Water from the RO system in the DM WATER PLANT will be mixed

with fresh bore-well water in the existing water sump and will be the feed to this

3000LPH RO System. We assume that this mix-water will have TDS of 2000ppm(maximum).The R.O.System is designed to have 50% recovery with 3000 Liters

per Hour of Permeate Water and 3000 Liters/Hour of Reject Water.

B) 1000 LPH RO SYSTEM:

The Reject from above 3000 LPH RO System will be the feed to this RO system.It is assumed that this feed water will have TDS of 4500ppm(maximum). The

R.O.System is designed to have 50% recovery with 1500 Liters per Hour of

Permeate Water and 1500 Liters/Hour of Reject Water.

WE PROPOSE TO MIX PRODUCT(PERMEATE) WATERS FROM THESETWO SYSTEMS AND PASS THROUGH A D.M.PLANT CONSISTING OFCATION COLUMN, DEGASSIFIER UNIT AND AN ANIOIN COLUMN

FOLLOWED BY MIXED BED UNIT TO ATTAIN THE QUALITY OF FINAL

OUTPUT WATER WITH TDS LESS THAN 5PPM.
