They are proud of their first-class reputation for the services that they offer within all areas of engineering and consultancy. This reputation is based on their collaborative ways of working, highly experienced staff, value engineering and innovation, alongside detailed design and ‘best practise’ solutions.

One specialist area of operation is the provision of chemical dosing systems for purchase or hire. Working closely with the Coal Authority to provide a bespoke and collaborative design utilising Hydrogen Peroxide dosing for the control of Hydrogen Sulphide in air, the Dissolved Oxygen control loop will mitigate the risk of odour release from this amazing new biological water treatment process.

Vital to verifying the efficiency of the dosing process is accurate and repeatable monitoring of hydrogen sulphide (H2S) down to single digit ppb levels, and, being aware of the stellar reputation of the Jerome J605, Leada contacted ABLE to arrange a site demonstration of the analyser. Having successfully put the Jerome through its paces, Leada ordered a fixed monitoring variant of the Jerome installed in a thermostatically controlled IP67 environmental housing. Whilst bespoke in some respects, the system was similar to those previously supplied to Thames Water, United Utilities, Tideway Tunnel and Southern Water.
