Water/Wastewater - UK Focus xv
Latest Analytical Technology Used to Ensure Biogas Efficiency
At Viridors’ Resource Recovery facilities in Stockport, the team uses Hach Lange (UK) instruments to closely monitor the entire process and to ensure that the plant's bacteria are provided with optimal conditions. These tests include chloride, pH, alkalinity and volatile fatty acids; the ratio of the latter two being the same as the FOS/TAC ratio, which is determined by a Hach Lange TIM Biogas titrator. In addition, samples are taken from the feed, the digesters and the effluent to monitor ammonia and COD with a Hach Lange spectrophotometer, ensuring compliance with the plant's discharge consent.
The Reliance Street plant utilises biogas to generate electricity and the residue from the AD process can be defined as a product rather than a waste because it complies with the BSI PAS110 Quality Protocol for Anaerobic Digestate (partly as a result of the monitoring that is undertaken).

Water Technologies Presented To Global Water Industry Leaders
Modern Water plc (UK), the owner of leading water technologies for the production of fresh water and monitoring of water quality, recently presented at the 2013 Citi Water conference in London which was attended by many global water industry leaders. The presentation on Water Scarcity Solutions: Desalination verses Water Reuse was given by Modern Water’s Executive Chairman, Neil McDougall and looked at how Modern Water’s innovative forward osmosis technology can help the world’s most water stressed countries.
The delegates heard how unlike traditional desalination, Modern Water’s forward osmosis process requires up to 40% less energy, produces a better quality of water with lower levels of contaminants, especially boron. Forward osmosis plants also have a far lower operational cost due to lower fouling of the membranes in the plant which therefore give the membranes a longer life as well as allowing the plant to continuously operate.
Modern Water’s Executive Chairman, Neil McDougall, commented: “We are delighted that forward osmosis has been recognised as one of the hottest topics in the water industry and that Modern Water has been given the opportunity to present at this prestigious event in the City of London.”
