Swimming Pools

The accuracy of the measurements made within your pool and of the supply water are critical. All equipment related to the regular testing of your pool should be recurrently calibrated to ensure this accuracy. DSW can calibrate the following equipment for you:

• pH probes
• Photometers
• TDS probes
• Conductivity probes
• The Free Chlorine and pH analyser

Ensure your results are accurate. Contact DSW today to guarantee your pool’s chemistry and arrange calibration of your equipment.

Traditionally pools are treated with chemicals to control bacteria that can enter via the incoming mains water or bathers. DSW can provide the following chemicals to assist with bacteriological and pool chemistry control:

• Sodium Hypochlorite
• Calcium Hypochlorite
• Sodium Bisulphate
• pH Minus
• pH Plus
• Eucalyptus Milk
• Chemical Heat Loss Barrier
• Polyaluminium chloride (PAC)

To ensure that bacteriological results remain within parameters and that pool chemistry is correct, it is critical to have suitably sized and specified pumps and a free chlorine/pH/TDS analyser. When designing your treatment system DSW give consideration to the following:

• Make up water supply characteristics
• Pool sizes and usage (bather loads)
• Circulation
• Historical bacteriological or chemistry issues
• Current monitoring and maintenance procedures/schedules
• Requirement for intelligent dosing including; auto priming pumps, timed pumps and degassing pumps

DSW are proud to be able to offer products from some of the world’s leading pump and analyser manufacturers, including:

• LMI
• Prominent
• Siemens
• Evoqua
• Grundfos
• Topline

All pools require suitable filtration for the purpose of backwashing. DSW can supply and install plants from new, including various vessel/media types and sizes. Types of filtration plant offered:

• Slimline filters (ideal for smaller pools and/or plantrooms)
• Easy to operate multiport valves
• Transparent filter tops to observe backwash and rinse
• Sand or glass media
• 2-part flanged vessels for plant rooms with access issues

If your plant requires remedial action or a complete overhaul, then DSW have the solution.

DSW understand that the safe and consistent operation of your swimming pool is critical to your business. All swimming pools are different, due to; supply water, size, materials of construction, bather load, and water turnover.
As pools vary so much it is critical to have a risk assessment undertaken in line with HSG 282 (spa pools) and HSG 179 (swimming pools) to ensure compliance. Our survey will look at the following areas:

• Paperwork audit of pool records completed by on site staff.
• Complete review of all operating procedures and control policies.
• Assessment of current control schemes and suitability for the pools.
• Physical condition check of the pool and surrounding areas prior to and following clean.
• Inspection of all treatment plants and associated systems, to include; chlorine/acid dosing, ozone, sand filters, balance tank, basket filters, strainers, gulleys, drainage areas, chlorine and pH analysers and probes, pumps, deadlegs, plate heat exchangers and injection points.
• Procedure review of cleaning and hygiene practices.
• Full COSHH survey.
• Assess potential for cross contamination and potential for foreign bodies to enter the pool via human contact.
• Any other considerations such as atmospheric conditions, materials used and general condition of the pool.
• Bather load and water turnover.
• Chlorine/ biocide dosing levels.

There are standard, regular daily, monthly and quarterly pool tests that must be undertaken. If you wish to supersede the minimum requirements or if you have historical issues with your pool water or make up water, you may wish to consider the following:

• Legionella, TVC, Total Coliforms, E.coli, Pseudomonas Aeruginosa
• Swimming pool chemistry suite 2
• Regular testing of Iron, Copper, and Zinc within the pool
• Independent UKAS analysis of day to day tests to confirm accuracy, such as: TDS, pH, and chlorine
• Sampling of sand/glass media for cryptosporidium

Ensure that your pool chemistry is well balanced and free of bacteria today.
