Who are WSS?

Founded in 1980, Water Software Systems (WSS) quickly established a reputation for applied research in water systems modelling, control and optimisation. WSS is part of De Montfort University's Department of Engineering, Faculty of Technology. 

The group's ethos is to research real water and wastewater systems problems, and develop and validate the results through industrial application. The team is multi-disciplinary and consists of specialists coming from a wide range of backgrounds such as control engineering, computer science, water and waste water engineering, electronics engineering and environmental engineering.

WSS pioneered the computer modelling of water distribution networks in Britain and the group's software has been applied to networks serving tens of millions to validate and compare different network designs and operational strategies. 


WSS has a state of the art water sustainability laboratory equipped with a set of pilot-scale units for the treatment of wastewater, range of laboratory devices for physico-chemical examination of wastewater and wastewater sludge and a high-performance computer monitoring and control system.

Our multi-configurable wastewater treatment pilot plant includes such units as: conical sedimentation tanks, buffer tanks, plug-flow step-feed activated sludge reactor and a sequencing batch bioreactor. It is equipped with state of the art sensors such as MLSS, COD, NH4-N, P-PO4 and SVI. In our wastewater testing facility we are able to perform chemical, biological and physical testing of water, wastewater and sludge samples.

In addition to standard physico-chemical procedures we are able to measure such parameters as: floc-size distribution, resistance to shear, viscosity and rheology of sludge, capillary suction time, specific cake resistance, flocculation ability, sedimentation properties, etc. This equipment allows us to pilot different processes in lab and pilot scale, derive and validate models and to test different control strategies. We have also access to a bio-chemical laboratory where all standard and non-standard wastewater measurements can be performed.

We have access to the following instrumental analysis apparatus: scanning electron microscopy, gas chromatography, mass spectrometry, high performance liquid chromatography and others.
