Our complete water treatment programmes prevent corrosion, scale and microbiological fouling by analysing your water to ensure your system is compliant with the current standards & regulations and use the correct treatment methods for the conditions of your system.

We have vast experience with various sites and assets and provide support in all aspects of chemical water treatment for industrial, commercial and leisure water systems, including:

  • Steam Boilers
  • Cooling towers
  • LPHW Systems
  • Chilled Systems
  • Swimming pools / Spa baths
  • Water features

Bespoke treatments can be developed to meet your requirements and Hydraclean can supply the relevant chemicals and equipment to ensure your system runs as efficiently as possible.

An effective closed system water treatment programme can prolong system life and ensure it is running as efficiently as possible, saving significant costs long term.

We sample and analyse your closed water systems for compliance with BS 8552 and BG50 which includes testing for the below:


  • pH
  • Conductivity/TDS
  • Physical Appearance & Solid Levels
  • Alkalinity
  • Hardness
  • Dissolved Iron
  • Total Aluminium (for LPHW Systems)
  • Total Copper
  • Molybdate
  • Nitrite
  • Isothiazolone
  • MEG (for Chilled Systems)
  • Additional tests are available on request


Microbiological Tests:

  • TVC
  • Pseudomonads
  • SRB (Sulphate reducing bacteria)
  • NRB (Nitrite reducing bacteria)


BG50 recommends that these samples are taken quarterly to monitor trends and for samples to be taken after any works on the system. We also offer UKAS accredited analysis and can provide all water treatment chemicals.

As Legionnaires’ disease is contracted through infected aerosols, cooling towers have become one of the most high profile methods of contracting the disease as they can create aerosols containing the bacteria. Common sources of Legionella include cooling towers used in open recirculating evaporative cooling water systems.

Hydraclean Ltd offers the complete service from technical support and microbiological analysis right through to chemical servicing, dosing and implementation of cleaning regimes.

The Control of Legionella Bacteria in Water Systems document, HSG 274 Part 1 sets out clear chemical and biological parameters which need to be tested. We aim to set out a clear and concise monitoring schedule which should be implemented to show what inspection and testing needs to be carried out weekly, monthly, 3 monthly, 6 monthly, annually and every 2 years.

We supply and maintain systems to HSG 264 part 1 using:

  • Automatic Dosing Systems / Equipment
  • Routine Sampling
  • Weekly / Monthly Analysis
  • Water Softeners
  • Water Treatment Chemicals

The Health and Safety at Work Act (1974) Section 2 requires employees to ensure plant and equipment is safe and without risks, this means that there is a responsibility to ensure there is no risk of infection from the pool water, or from any other system on the premises.

Regular testing of pool and spa facilities is required to ensure the safety of swimmers visiting your premises and it also plays an important role in protecting the infrastructure of your pool. Effective water management enables the optimism of your treatment plan, maintaining water balance and disinfection control.

Daily pool water testing is required to effectively monitor pH levels and disinfectant residuals such as chlorine and bromine, to prevent chemical irritation for swimmers. To maintain water quality, weekly tests must also be carried out to test parameters such as alkalinity, total dissolved solids, calcium hardness and water balance.

To eliminate the risk of recreational water illnesses, microbiological pool and spa tests must be done at least monthly. Microbiological testing is critical in stopping the spread of bacteria and viruses.


Hydraclean Ltd offer the following services for your pool / spa:

  • Full monthly chemistry testing of pool and spa water
  • Full microbiological testing for TVC, E. Coli and Coliforms & Pseudomonas aeruginosa. Legionella sampling (spa pools)
  • Calibration, services or replacement of pool plant equipment (pH, ORP probes)
  • Supply of all pool and spa water chemicals and testing equipment for staff to carry out daily/weekly checks
  • Technical advice on maintaining a good water balance and disinfection control and what procedures to put in place if things go wrong
  • Service and replacement of filtration equipment

Please note: Hydraclean Ltd can also offer all of the above on decorative water features.

Poor maintenance of any boiler results in scale formation and corrosion. This will affect efficiency, and increase energy consumption leading to shorter plant life.

We supply and maintain systems to BS2486 using:

  • Automatic Dosing Systems / Equipment
  • Routine Sampling
  • Weekly / Monthly Analysis
  • Water Softeners
  • Water Treatment Chemicals
