BHRSolutions has a wealth of test facilities and methodology applicable to the water treatment industry.

Hydraulic Modelling
BHR Group have gained a vast experience of building and testing models of hydraulic structures such as pump sumps, inlet works, dam spillways and drop shafts. Our workshop is skilled in producing accurate models in wood, fibreglass and Perspex and space for large models is available in our 60m by 40m hydraulics laboratory.

Mixing
An extensive range of experimental techniques for assessing the performance of mixers has been developed by our consortia projects FMP and WWM. Laser Induced Fluorescence (LIF) and Conductivity techniques are used to measure the Coefficient of Variation (CoV). Tracer testing is also used to help ascertain the performance of mixing systems. Our facilities include:

• Flow loops for testing pipe mixers ranging from 25mm to 150mm diameter
• A 15m channel for testing channel mixing devices such as weirs, flumes, baffles and static mixers
• Simulant identification and formulation. Fluids with a range of viscosities, from water to highly viscous sludge simulants, can be utilised as additives or bulk flow.

And see our Mixing Technology pages for:

• An extensive collection of stirred tanks ranging from 0.3m to 1.8m in diameter, for modelling water and wastewater treatment process systems such as flocculators, sludge storage tanks and anaerobic digesters
• Further information on our pipe and channel static mixer test facilities
  

Sludge Rheology
Using our well-equipped static laboratory and portable site testing equipment, our comprehensive sludge rheology measurement services include:

• Rheological measurements carried out at temperatures and shear rates appropriate to the client's specific requirements
• Dry solids measurement
• Data delivered raw or fitted to an appropriate mathematical model.

Equipment Testing
See our Fluid Systems pages for our extensive range of facilities for testing pipeline and other system equipment and fittings including testing for pressure, performance and wear.

Residence Time Distribution
Residence Time Distribution (RTD) tests can provide invaluable information on the performance of process systems.

BHRSolutions has significant experience in conducting Residence Time Distribution (RTD) tests in both the laboratory and the field to support physical and CFD model studies. For example, digesters, service reservoirs, clarifiers and mixing systems can be tested to identify if they might be performing poorly or indeed to specification.

A variety of chemicals can be used as tracers depending on site conditions and restrictions on client's business.
