COMACOE adds BARC to its list of clients!

COMACOE is proud to announce the receipt of award of SWIO system from BARC for desalination system at Gopalpur, Odisha.

Bhabha Atomic Research Centre (BARC) is setting up a 5.0 MLD hybrid sea water desalination plant comprising of 4.5 MLD sea water reverse osmosis (SWRO) system and 0.5 MLD multi-effect distillation (MED) system within the existing premises at Orissa Sands Complex (OSCOM), Indian Rare Earths Limited (IREL), Matikhalo, Dist: Ganjam, Odisha.

The Desalination plant requires sea water at the rate of about 1000 cu.m/hr (i.e 24 MLD) to be drawn from Bay of Bengal and will discharge reject brine of about 800 cu.m/hr to the sea.

In a competitive bidding process, COMACOE was declared to the successful bidder and awarded the contract on EPC basis.

Sea water is planned to be drawn from a distance of about 900 meter in the open sea where a cupronickel intake filter is located at a depth of 11.4 meter below chart datum (CD) / at – 12.9 m from mean sea level (MSL).The seawater flows through buried 900 mm DN (O.D) HDPE, PE 100, PN8 pipeline, with at least 1.5 m cover over the anchor block. The HDPE main conveyance line and 4 nos. of 63 mm DN (O.D) composite HDPE/Aluminium pipes are to installed external to the main conveyance pipeline with proper supports and anchorage. The offshore intake pipeline is connected  to  900 mm O.D pipe header through manual operated gate valve. The raw seawater flows into six nos.  of basket filters where seawater is coarse filtered. The filtered seawater enters suction of four nos. (3 working+1 standby) of horizontal split casing centrifugal pumps through a 900 mm OD header. The pumps supply seawater to desalination plant facility site through buried 630 mm O.D HDPE line of PN 10 rating. Reject Disposal System consists of Reject water tank & Brine disposal pumps at Desalination plant facility site and thereafter, buried single onshore pipeline & submarine pipeline up (PN 10) to offshore multiport diffuser at 800 meter inside the sea where water depth is 12.1 meter & 270 meters away from the offshore intake point.

Brief scope of work includes:

• 1 x 975m intake line 900mm dia
• RCC caisson intake well depth of approx. -11.5m
• 1 x 875m outfall line 500mm dia with Multi port diffusers
• Air bursting system
• Chlorination system
• Construction of pump house including all civil, electromechanical and E&I work
