Cleaning and Chlorination Services
Foztek offers a wide range of high quality cleaning services to HSE ACoP L8 as part of our comprehensive Water Hygiene Management Programme.
Cleaning and Chlorination of Water Storage Vessels
Foztek can undertake the clean and chlorination of all forms of water storage tanks, ranging from a small one piece polypropylene storage tanks through larger sectional vessels to underground reservoirs. Foztek can offer use of the following chemicals in completion of required chlorination works:
Silver Hydrogen Peroxide
Clean and Chlorination of Hot & Cold Water Services [BS 8558]
Foztek can undertake the chlorination of domestic hot and cold water systems; this can be by way of a routine chlorination or after a tank or pipework installation. We can also undertake the chlorination of mains fed water systems by way of direct injection. Foztek use both Chlorine Dioxide and Sodium Hypochlorite as required.
HSG 274 (part 2) recommends annual internal inspection of domestic hot water calorifiers (Table 2.1, page 31); Inspect calorifier internally by removing the inspection hatch or using a boroscope and clean by draining the vessel. The frequency of inspection and cleaning should be subject to the findings and increased or decreased based on conditions recorded.
Showerhead Cleaning, Descaling & Disinfection
HSG 274 (part 2) recommends that showerheads and spray taps should be treated quarterly or as indicated by the rate of fouling or other risk factors: Dismantle, clean and descale removable parts, heads, inserts and hoses where fitted.
New heating and chilled water pipework systems require the removal of contaminate debris such as milli-scale, jointing compounds and building debris. These contaminants could increase the risk of blockage at strainers and small bore control valves.
Advances in modern day systems have made the process of pre-commission cleaning an essential procedure to facilitate maximum plant efficiency.
Foztek can undertake specialist chemical cleaning (where required), biocide washes (where required), flushing and system inhibition of all closed pipework systems.
Microbiological Sampling & Analysis [including Legionella]
Many clients throughout the UK require routine water sampling with analysis completed by independent UKAS accredited laboratories. Typical water analysis testing includes:
Total Viable Counts (TVC) – at both 22°C and 37°C
Sulphate Reducing Bacteria
This is not a comprehensive list, but the more common analyses are completed daily by Foztek. If you have a specific problem, then please contact us to see how we can help you.
