WRc, the Group's core business, is dedicated to improving the efficiency and effectiveness of water utilities and their associated regulatory organisations. WRc addresses the operational performance of water utilities and their regulatory aspects through WRc Consulting and three technology areas - Processes, Networks and Environments. The software can be used to simulate individual treatment processes or the whole treatment works, including sludge treatment processes, septic tank imports and recycles. The model enables the user to optimise the response of the works to changes in the influent loads, works capacity or process operating conditions. The software is used by the majority of the UK waster utilities, a range of international consultancies and municipalities in the USA and Europe.
Users benefit from a dedicated team of developers and support engineers .
During its development, each process model was validated against performance data from sewage treatment plants. Extensive modelling work has subsequently been undertaken to confirm the validity of individual process models. The Windows interface allows users to quickly build a plant model and enter the data using simple dialogue boxes. Results can be shown while a simulation is taking place and are stored as data files for subsequent analysis. Comparisons were made on the basis of effluent quality, sludge production, effect of increased loads and overall capital and operating costs.
