The key to effective water treatment is integration. By effectively integrating systems, facilities will be able to increase energy and operational efficiency, which ultimately reduces operating costs.
Many operators of sports and leisure centres are unaware of the levels of savings that can be achieved through adopting an integrated solution, which will optimise energy, water and chemical usage, while maintaining optimal water quality conditions – a key performance indicator for customer satisfaction.
In the case of swimming pools, Siemens offers an innovative energy and water optimisation system (EWO), which has a modular design so operators can select the right elements for their facility. The DEPOLOX® Pool controller by Siemens sits at the heart of this system. It continuously monitors all of the critical water quality parameters, automatically controlling the addition of disinfectant and pH correction to reflect the changes in the pool.
The controller can be offered with options to measure the combined chlorine, TDS and redox value on an ongoing basis. This means that if the pool water is within the user defined limits, the DEPOLOX® Pool controller can signal to the pool’s flow meters and the variable speed drives to reduce their speed.
Should this quality deviate, the controller does the reverse and normal circulation levels resume. Crucially, this is where significant energy savings are to be made and water quality can be maintained – even as bathing loads fluctuate.
Through the installation of SED2™ variable speed drives, facilities can save up to 50 per cent on the energy consumption of circulation pumps.
Further savings can be made by using a UFOX sludge water recycling system. It can reduce water consumption by safely recovering 80 per cent of backwash water to the highest standards, so it can be reused for functions including pool filling or toilet flushing.
For ultimate efficiency, integration should span a facility’s complete water system. These should also use low footprint technologies for the best use of space and ensure a safe environment for customers.
At Siemens we can offer a total water treatment solution, from rainwater harvesting through to cooling towers and sterile cleaning to meet these objectives.
