Water Management


A reverse osmosis unit is one of the technologies in a bespoke solution for improving water quality for CHP.


Liquid assets Think about water quality early for long-term CHP efficiency, advises Jim Baker. C


ombined heat and power (CHP) is becoming an increasingly attractive technology. A raft of government financial incentives offset the initial high capital expenditure and initiatives including reduced business rates and exemption from Carbon Price Support make long-term operation attractive too. However, the operating efficiency of any CHP unit depends on the efficient generation of electricity and the effective use of the associated heat, requiring effective use of boilers. Highly efficient long-term operation and reduced maintenance can be accomplished if attention is given to the quality of water used in the system and considerable savings can be

made if this is considered early in the design stage. Culligan is a water treatment specialist with an


extensive track record of treating water upstream of CHP units and district heating systems across Europe. “All process industry works hard to deliver high-quality products with a keen eye on reducing overheads. When it comes to being energy efficient, CHP makes sense together with considering using alternative water sources to mains. Early consideration to achieving good water quality feeding the CHP and the design of a cost- effective treatment plant will pay dividends,” says Chris Smith, director of Culligan UK. At the heart of CHP systems is a more efficient way of generating power. In a conventional power station
