BENEFITS :
• The purpose of incorporating Ultrafiltration system is to remove Coloidal silica, suspended particles & Bacteria & SDI, thus enabling the RO plant to operate at a higher flux rate.

• Providing State-of-art-Ultrafiltration system, by eliminating conventional system -lime dosing for reduction of Coloidal Silica to the acceptable limit to RO system.

• Provision of UF system enhance the life of the RO membranes and also increase the frequency of chemical cleaning.

• Membrane based technology gives consistent water quality even in wide variations of feed water quality

• Lower foot print

• No Sludge

• Lower operating cost

• Less maintenance Cost

• Less man power

• Eco-friendly system

OBJECTIVE :
TO DESIGN THE PLANT FOR CAPABLE OF DELIVERING THE TREATED EFFLUENT, WHICH WAS DISCHARGED TO THEIR SOLAR EVAPORATION POND. MTL SUGGESTED BIL THAT THIS QUANTITY OF TREATED EFFLEUNT CAN BE RECYCLED BACK TO THEIR PROCESS, THUS ENABLING THEM TO REDUCE THE RAW WATER CONSUMPTION.

SCHEME PROPOSED :
PRETREATMENT  -  ULTRAFILTRATION SYSTEM  -  REVERSE  OSMOSIS SYSTEM STAGE I  -  OSMOSIS SYSTEM STAGE II

DESIGN BASIS :

S. No.	Parameters	Units	Feed Quality	Treated Water Quality
1.	Total Dissolved Solids	Ppm	5000	< 500 [at II Stage]
.......................................................................................................................................
2.	TSS	Ppm	30	BDL
.......................................................................................................................................
3.	Silica	Ppm	40 - 50	< 2

BENEFITS :
• The resin based DM Plant discarded from the operation thus eliminating the regenerant effluent and high maintenance cost.

• Consisting quality in treated water quality to their process

• Less man power

• Minimum quantity of Sludge

• Lower operating cost

• Eco friendly system

• The final reject for discharge reduced 8.0 M3 / Day and hence reduction in area for the reject disposal

• Providing State-of-art-Ultrafiltration system, by eliminating conventional system and lime dosing for reduction of Colloidal Silica & SDI to the acceptable limit to RO system.

• Provision of UF system would enhance the life of the RO membranes and also increased the frequency of chemical cleaning.

• Lower foot print

• Eco-friendly system

OBJECTIVE :
TO DESIGN THE PLANT FOR CAPABLE OF DELIVERING THE WATER, TO THEIR BOILER FEED & COOLING TOWER MAKEUP.

SCHEME PROPOSED :
PRETREATMENT  -   REVERSE  OSMOSIS SYSTEM WITH PROPRIETORY ANTISILICA RO SYSTEM

DESIGN BASIS :

S. No.	Parameters	Units	Feed Quality	Treated Water Quality
1.	Total Dissolved Solids	Ppm	1100	150
.......................................................................................................................................
2.	Reactive Silica	Ppm	64	< 4
.......................................................................................................................................
3.	Total Hardness	Ppm	< 30	628

BENEFITS :
• MTL provided Proprietory Antisilica RO system, due to the high silica content in the raw water, thus eliminating the lime dosing, clarifier for precipitation of Silica

• Eliminates Sludge

• Lower operating cost

• Less man power

• Less maintenance cost

• Eco friendly system

OBJECTIVE :
TO DESIGN THE PLANT FOR CAPABLE OF DELIVERING THE TREATED EFFLUENT, TO THEIR BOILER FEED.

SCHEME PROPOSED :
PRETREATMENT  -  ULTRAFILTRATION SYSTEM  -  REVERSE  OSMOSIS SYSTEM STAGE

DESIGN BASIS :

S. No.	Parameters	Units	Feed Quality	Treated Water Quality
1.	Total Dissolved Solids	Ppm	836	< 100
.......................................................................................................................................
2.	Total Hardness	Ppm	330	BDL
.......................................................................................................................................
3.	COD	Ppm	59	< 10 Ppm

BENEFITS :
• To cease procurement of DM water from other vendors and suppliers

• Logistics involved in handling the water tankers

• Become self sufficient, thus eliminating the dependency on 3rd party for the DM water / raw water

• No Sludge

• Lower operating cost

• The final reject for discharge reduced 8.0 M3 / Day and hence reduction in area for the reject disposal

• Providing State-of-art-Ultrafiltration system, by eliminating conventional system and lime dosing for reduction of Coloidal Silica & SDI to the acceptable limit to RO system.
