Measurement of Biochemical Oxygen Demand «MB – BOD»
Microbial biosensor for measuring and monitoring the Biochemical Oxygen Demand (BOD)
WOLA MB-BOD technology is robust, reliable, rapid and monitors continuous data to help to determine the source of polluting discharges, vital to regulatory bodies and facilities likely to cause spillages.
Excess organic matter is the primary pollutant of aquatic ecosystems, its source often in effluents from municipal or industrial wastewater treatment processes and livestock activities.
Organic matter discharged into the natural environment alters the level of organisms that live in watercourses by decreasing the levels of dissolved oxygen.
BOD measures the amount of oxygen consumed by the microbiological oxidation of organic matter present in water, under controlled conditions, it is a difficult technique to automate. This parameter best reflects the impact of organic matter in a natural environment, water eutrophication and its capacity for self-purification, but it takes five days to obtain a result. The presence of solvents, chlorine or disinfectants negatively affects the development of the test, too.
Our system is not affected by microbial activity inhibitors and it is eco-friendly – we do not use toxic reagents or generate harmful waste.
Over 210,000 hours of uninterrupted operation support the robustness of our MB-BOD device. Moreover, it is patented and supported by several Spanish organizations (Spanish Ministry of Public Works, CSIC and Government of Andalucía Region) and it is also verified by EU environmental and science bodies (PROMOTE-ETV, BIOSET, Concerted Action).
MB-DBO equipment has the following key features:
- Short time analysis (45 minutes) and it takes 15 minutes of self-washing after each analysis.
- Low cost analysis.
- Low operational cost.
- Frequency of analysis is fully programmable by the user.
- Online control Interface: mobile phone, website, tablet..
- Early Warning – above parameter limits – samples capture for an eventual/utter analysis in a laboratory.
- Self-cleaning device.
- Use of new sensor microorganisms in each analysis. In this way, sensor microorganisms couldn´t be affected by toxics that could have the previous analysed samples.
- Good correlation with the classical analysis BOD5 (in laboratory).
- Continuous results facilitate quick information-backed and decision-making
- Maximum functionality, simple and ease of use device
- Low detection limits.
- Does not require the use of reagents.
- Monitor inflows and effluents of water and wastewater treatment plants.
- Source detection of water pollution.
Automated analytical equipment highly important, among others, in the following applications water quality monitoring process: water treatment and reuse, waste water treatment plants (WWTP) functioning, polluting industries, fish farming, aquaculture, hydroponic systems and environmental control – rivers, lakes, wetlands and beaches – in order to:
Adapt water treatment to the incoming organic matter – and eventual energy saving, CO2 print reduction and management cost optimization.
Ensure that treatment processes are working optimally.
Guarantee effluents comply with the corresponding regulations to avoid environmental damage.
- Fish farms
- Wastewater treatment plants
- Polluting industries
- Protected areas
OPTIMIZE YOUR FISH FARM:
MONITORING BIOCHEMICAL – MICROBIOLOGICAL PARAMETERS IN “REAL TIME”
Online Monitoring of essential parameters to know an optimize metabolic and microbiological processes in applications such as: Biofermenters, Fish farms, Obtaining metabolic bio-products, Bioreactors, Decontamination processes, Microbial Counting, Concentration of toxic effects, etc.
Don’t take a risk in your fish farm: monitoring of Biochemical Oxygen Demand (BOD). Quantify the Total Water Toxicity and the concentration of aerobic living microorganisms in «real time» in your Fish-Farm and other water uses.
“Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use” by the OECD
Water eutrophication has to be monitored to control and protect the functional balance that guarantees a process (Fish-farms, rivers, wetlands, reservoirs, etc.) The information provided by the three analytical biosensors developed by WOLA makes it possible to monitor with efficacy the eutrophication.
CONTROL AND OPTIMIZATION OF THE WATER USE – WWTW
A SOFTWARE DEVELOPPED SPECIFICALLY FOR THIS BIOSENSOR ALLOWS A REAL TIME MONITORING OF THE RESULTS.
You can know the contamination due to organic matter in water, and optimize the treatment process of your Waste Water Treatment Works (WWTW), in order to obtain the best results.
With our MB-BOD water samples at an inlet (red) and outlet (blue) of a waste water treatment plant can be monitored.
