Research has begun.

Posted by lowell lewis on April 30, 2010 at 6:18am

I am pleased to announce that a 4 year research project into optimising sustainability, performance and public health protection in the design and operational life cycle of sports and leisure pool complexes has begun. The research, funded by EPRSC and DEFRA, is based at the new state of the art Surrey Sports Park at the University of Surrey, UK.

Main objectives for the project are to investigate various energy and sustainability issues relating to swimming pools as well as to collect and analyse water quality data associated with different user groups and pool configurations. An interactive model is to be generated using CFD to allow consultants to make informed decisions during the design phase.

I welcome any interest in the work that is being carried out and am happy to hear from anyone who would like to contribute to the ideas table.

    The pool circulation pumps are fitted with variable speed drives so they can be set to operate at full speed (180m3/hr) or a reduced rate. There are currently 5 pre-set rates. (100%, 80%, 70%, 60%, 50%) although we have the ability to set them at any value.

    How do you adjust the speed?

    The pool is open to users between 6am and 10pm daily. Overnight the circulation system is turned down to 50%. Other than that no other changes are made to the pool during the hours it is closed.

    Is the pool operating on a 24/7 schedule?

    One of the aspects of the work will involve the monitoring of DBP concentrations in the pool and the associated treatment plant on a regular basis. The pool is currently being opperated at 1.5ppm FC although we intend to drop it down to near the 0.5ppm mark. We will not be using cyanuric acid at this facility.

    Are they going to be measuring disinfection by-products (DBPs) either in the pool water or in the air above the pool, such as nitrogen trichloride? If so, then I'd like them to measure what happens in an indoor pool when no CYA is being used compared to a pool where CYA is used. The no-CYA case can be at the German DIN 19643 standard of 0.3-0.6 ppm FC with no CYA (0.2 to 0.5 ppm FC if ozone is also used) OR it can be the more typical American values of 1-2 ppm FC with no CYA -- preferably the latter since the difference will be greater. For the CYA case, it should be 4 ppm FC with 20 ppm CYA which is roughly equivalent to 0.2 ppm FC with no CYA.
