Award-winning HYBACS Upgrade at Tubli WPCC, Bahrain Project Name: Tubli WPCC (Phase 1)
Client: Ministry of Works (MoW), Bahrain
Capacity: 100 MLD/500,000 P/E
Project Value: £14.7m
Main Contractor: Bluewater Bio

Project Overview

The existing activated sludge plant at Tubli Water Pollution Control Centre (WPCC) was designed to treat a daily flow rate of 200,000m³/d. However, due to the continuing rapid growth of Bahrain, the present flow rate into the works was in excess of 300,000m³/d and this is only expected to increase in the future.

The Bluewater Bio solution, based on its proprietary HYBACS® secondary treatment process, comprised of the conversion of 2 of the 10 aeration lanes and 4 of the 12 clarifiers into a HYBACS plant, by installing 42 SMART™ units upstream of the aeration lanes. The upgraded HYBACS plant treats 100,000m³/d meaning that the two aeration lanes, originally designed for 40,000 m³/d, now have a 150% uplift in capacity.
