Early results from Bluewater Bio International’s HYBrid ACtivated Sludge wastewater treatment upgrade at Bahrain’s Tubli Water Pollution Control Centre show an overall improvement in nitrogen removal of 80%.

The Bahraini Ministry of Works said that the HYBACS upgrade at Tubli had alleviated the current overloading problem without the requirement for green-field construction, thereby utilising the existing secondary treatment assets whilst avoiding additional land take. The Ministry commented:

“ Early results demonstrate that the plant is operating exceptionally well and meeting the highest standards, with an overall improvement in nitrogen removal of 80%".

Bluewater’s Technical Director, Dr. Jeremy Biddle said that during commissioning in September and October, the HYBACS plant at Tubli treated 20% more flow than its design average and nitrified fully, whilst demonstrating substantial power savings of up to 40%.

Last week the award-winning provider of high-performance water and wastewater treatment technologies hosted a site visit to the plant following recently-completed performance testing of its HYBACS® wastewater treatment upgrade. Performance testing of the upgrade concluded on 6th January 2014 with no failures, despite very high influent COD loads. With, Bluewater Bio has now entered a one year operation and maintenance contract at Tubli WPCC.

The site visit was included by the UK Embassy in their programme for Great British Week (www.yallabahrain.com). The visit also included a timed demonstration to illustrate the vastly improved sludge settling of effluent from the two HYBACS lanes, compared with effluent from the eight lanes not yet upgraded.

Daniel Ishag, founder and CEO of Bluewater Bio, commented: 

 “Now fully commissioned, the HYBACS upgrade at Tubli is consistently outperforming all the Ministry’s specifications and expectations. As such it provides a compelling reference site for Bluewater Bio to showcase with current and future partners across the globe.”
