Biocide Programmes
KEM provides novel biocide programmes including Silver Stabilised Hydrogen Peroxide, Chlorine Dioxide, Ozone, Metal Ionisation and UV filtration.

Non-Compliances
KEM will assess the current water system and note areas of non-compliance (e.g. scale, corrosion or foreign bodies). The water will be tested for pathogens.

Subject to findings, our consultant will prepare a report with any recommended remedial works. A quotation will be provided to bring the system into a compliant state.

Water Treatment Services

KEM provides comprehensive water treatment services throughout the United Kingdom. All work is carried out in accordance with current legislation and following guidelines from relevant regulatory and advisory bodies. These services include:

Boiler Water Treatment
With clients ranging from the power generation sector, the food industry and plant nurseries, we understand that steam-generating boilers require a 'complete system' approach to ensure successful, problem-free operation.

Closed System Water Treatment
We provide regular analytical services during which we monitor the waterside conditions. Our extensive range of treatments takes into account system metallurgy, make-up water and operational conditions.

Cooling Water Treatment
We provide a comprehensive cooling water treatment programme which encompasses all aspects of the client's process. The benefits include maintaining cooling efficiency and therefore minimise energy wastage, providing compliance with current Health and Safety requirements, having minimum impact on the environment and extending plant life / reducing maintenance.

Effluent Water Treatment
At KEM we meet with our clients to identify the complex requirements of their processes to minimise effluent, and then design a programme to enable our clients to conform to discharge limits and improve quality for reuse of water. We have complete effluent water treatment programmes.

Comprehensive Water Treatments

Water Pre-Treatment
The rising cost of water is forcing users to source water from various locations that are variable in quality. We can help design systems to remove all unwanted components in your water source.

Typical pre-treatment plant can include filtration, activated carbon filtration, softeners, reverse osmosis, demineralisation, UV filters, break tanks and booster pump sets.

Our commercial team will design a contract that satisfies your financial needs and ensures strict compliance.

Repair and servicing works can be provided to existing pre-treatment installations and spare parts are available for most systems.

Legionella Risk Assessments

Risk Assessments
The Risk Assessment forms the basis of a control scheme which is implemented and regularly reviewed to ensure its effectiveness. The control scheme will vary in complexity from site to site but our extensive services include:

    • Risk assessment log books
    • Microbiological analysis of samples to UKAS accredited standards
    • Temperature profiling
    • System cleaning and disinfection
    • Remedial works to WRAS approved standards

Legionella & Legionnaires' Disease
Legionnaires’ disease is a potentially fatal type of pneumonia caused by legionella bacteria. It takes its name from the first known outbreak at an American Legion convention in Philadelphia in 1976. Infection is caused by inhaling small droplets of water contaminated by the bacteria, from sources such as showers, whirlpool baths and cooling towers. People over the age of 45 are more susceptible to infection, as well as smokers and people whose immune system is impaired.

Initial symptoms are similar to those of flu, including headache, high fever and vomiting, followed by more severe symptoms which can include breathing difficulties and hallucination. Legionnaires’ disease is most often treated with antibiotic drugs and recovery often takes several weeks.

Legionella Prevention
Legionella bacteria may grow in water systems such as cooling towers and hot and cold water services. They survive low temperatures and thrive at temperatures between 20°C-45°C, especially where there is scale, corrosion and other bacteria. A risk assessment should be carried out to identify any sources of risk.

KEM will visit your premises to carry out an assessment of your water services, identify any problems, put in place control measures including temperature monitoring and hygiene checks, modify any systems which are at high risk from legionella contamination, take water samples for testing, and treat any existing bacteria.

We follow the strict guidelines laid out in HSE ACoP L8 for legionella prevention in the United Kingdom.

Air Quality Monitoring in London
Air Quality Services

Assessments of the Occupied Air Space
Inspections identify critical environmental issues within the workplace, which can increase productivity, reduce sickness and absenteeism (so-called ‘Sick Building Syndrome’). Findings include Temperature Analysis, Relative Humidity (RH), Carbon Dioxide, Airborne Particles, (Respirable and Non-Respirable Dust), Airborne Bacteria/Fungi, and visual inspection of the occupied workspace reviewing all aspects of air quality including capability and limitation.

Carbon Dioxide
Unusually high carbon dioxide levels may cause drowsiness and headaches and reduced productivity of occupants.

Bacteria / Moulds
The primary hazard of mould in indoor air quality is the triggering of asthmatic attacks in susceptible persons. The monitoring of humidity levels will inhibit the likelihood of mould growth.
