Wastewater Treament for Distilleries

by B & V Water Treatment     based in Daventry, UNITED KINGDOM

B & V Effluent Services have been successfully helping brewers and distillers throughout the UK with the management of their effluent systems for nearly 30 years. As a result the B & V Effluent Team holds a vast amount of specialist knowledge in regards to the problems faced within the alcohol industry including Copper Removal from discharge water and the management and reduction of pollutant levels in general to meet discharge limits.

TOC Correlation to BOD or COD

by GE Analytical Instruments     based in Boulder, COLORADO (USA)

Challenge: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are traditional parameters analyzed in the laboratory to determine organic matter in water and wastewater. Wastewater facility operators need to have constant data to monitor their discharges and optimize treatment processes (biological treatment, chemical dosing, etc). The requirements of BOD and COD analysis prevent them from being implemented as control parameters, however. The BOD five-day analysis time requirement does not allow an operator to use the data for process optimization and. although COD requires less time than the BOD, its analysis includes the use of hazardous chemicals and has no constant analysis capability.

Water Treatment for Food Production

by B & V Water Treatment     based in Daventry, UNITED KINGDOM

B & V Effluent Services has been providing waste water management services to the food production industry for a number of years. As a result of this wealth of experience B & V Effluent services have a high level of technical expertise when it comes to providing a service to this industry in particular.

Wastewater solutions for the industrial effluent pollution management

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Problem: Industrial manufacturers face stringent regulations for discharging wastewater to the environment and municipal sewer systems. Biochemical Oxygen Demand (BOD) is a primary concern for many discharge limits, as wastewaters high in BOD can have adverse impacts on the aquatic environments by leading to oxygen depletion. In some cases, as a means to supplement BOD, it is also desirable to monitor chemical oxygen demand (COD) of industrial effluents. Both of these tests, are time and labour intensive reducing the frequency at which they can be measured for a given effluent.

Water quality monitoring for brewery industry

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Monitoring process streams and waste streams continuously in a brew house can provide many benefits to operations. Monitoring product in process for color or concentration provides consistency and quality measures. Product loss can be quantified by monitoring waste streams. Processes can be improved to increase efficiency and minimize effluent waste. Effluent waste streams can also be monitored for organic loading with BOD and COD correlations to ensure compliance for discharge.

Oxygen Monitoring from Aerobic and Anaerobic for Biomass Activity Tests

by Respirometer Systems and Applications, LLC     based in Springdale, ARKANSAS (USA)

Pulse-Flow respirometers can be used to assess biomass activity for aerobic and anaerobic reactions. In aerobic tests, cultures are combined with nutrients, trace minerals, and an organic substrate – such as acetic acid or ethanol. The maximum oxygen uptake rate reflects the amount of active biomass in the test culture.

Online water analysers for process water and waste water industry

by LAR Process Analysers AG     based in Berlin, GERMANY

Process and waste water are the most challenging water for instrumentation. Mostly, these water are characterized by highly fluctuating loads, very high salt concentrations as well as a high particle density. Hence, the accurancy and speed of measurement depends on the measurement system itself and the used oxidation technique. Obviously, application-specific analysers provides huge advantages against standard analysers, that are used for every application.
