been used to connect mag-meters. Installing fl ow measurement systems requires a specialist expertise beyond the capabilities of most Civil Companies. Therefore, when installing new fl ow measurement kit, it is strongly recommended that Process Operators use only specialist companies who understand both the MCERTS requirements and how fl ow measurement systems work.

One of the most frustrating things for Process Operators is when their site fails its MCERTS inspection because they have installed a new or replacement fl owmeter that is not MCERTS approved. All Flowmeters installed after April 2010 must hold suitable product certifi cation under the MCERTS standard. Exceptions are only made if there is no suitable MCERTS certifi ed product available for the specifi c installation and the regulator agrees this in writing. Clearly, purchasing non MCERTS approved kit for MCERTS applications can be a very costly mistake, but ultimately, this requirement helps to keep fl ow measurement standards high by ensuring that only good kit is used. Of course, there are some very good fl ow-meters on the market that are not MCERTS approved and can be used for other fl ow applications.
Another question I am often asked on site is - Where do you see the MCERTS scheme heading in the future? The answer I give, in short is that it is going to expand massively. The MCERTS
scheme has an ambitious outlook for the future. The number of locations where MCERTS inspections are required is going to hugely increase with the most signifi cant increase being at Combined Sewage Overfl ows (CSO’s) and sewage pumping stations – the sites responsible for the sewage spills often reported in the news. Currently, most MCERTS fl ow applications are located on sewage treatment works or factory effl uent plants monitoring fl ow measurement under normal fl ow conditions. More MCERTS inspections will be required for storm events. These can be located anywhere within the sewage network where there are combined sewar over-fl ows (CSO’s.) The majority of CSO’s are already monitored by the Process Operators, but the new standards will improve this monitoring by enforcing a standard. Process Operators are already upgrading their CSO monitoring to MCERTS Standards. Access issues are very much the focus of discussion within MCERTS companies. CSO’s are often deep underground, or under roads. Accessing these points, could mean closing a road so that the MCERTS Inspector can gain access to the CSO which could be located deep underground. This will have implications on the training of staff and the safety equipment needed to carry out the inspection. However, MCERTS companies are ultimately in favour of these changes as implementing and enforcing standards can only be a good thing for water quality in the UK.

Multi-point on-site water quality monitoring made easy
Keep track of microbiological contamination with the automated BactoSense Multi
BactoSense Multi belongs to the family of on-site water monitoring instruments from bNovate Technologies. It allows simple and fast analysis of multiple samples from diff erent sampling points within water plants, bottled water companies, or any production facility where water quality is a crucial parameter.
A reusable cartridge with all chemicals tightly sealed makes BactoSense Multi a sustainable and safe instrument. Not only does it help keep the overview on your water quality, but it also supports your process optimisation.
eventually present at any point of a water network and ensures the biostability of the system. The entire measurement procedure, from sampling to reliable results is very easy to perform.
Three simple steps from sampling to reliable on-site results
The operator takes up to 30 water samples, places them in the sample tray and starts the measurement via the touchscreen – BactoSense Multi does the rest without any further human interaction, even overnight.
BactoSense Multi delivers precise results rapidly and allows quick, well-informed decision making. Users get a clear understanding of the quality of their water sources without having to wait for results from an external laboratory – which often take several days to arrive.
Don’t bring the sample to the laboratory, bring the laboratory to the sample
bNovate’s cutting-edge industrial fl ow cytometer is a very cost-eff ective and fast complement to traditional plating techniques to monitor water quality. BactoSense Multi brings the laboratory to the production line, providing a new level of automated, reliable water analysis.

BactoSense Multi is a user-friendly fl ow cytometer developed by bNovate Technologies, the Swiss pioneer in automated cell analysis. It enables water plants and bottled water companies to have a complete and accurate microbiological overview of the water quality at every step of their processes. Its features complement bNovate’s BactoSense instrument for online measurements, which provides fast results in only 20 minutes.
This water monitoring instrument precisely counts the bacteria
Having in-house measurements is of great benefi t: enabling lightning-quick decisions. It can assist for the cleaning and disinfection of pipes or the immediate treatment of water, but it will also support any process optimisation on your line.
A sustainable solution for multiple water monitoring applications
Additionally, BactoSense Multi is a safe to use and sustainable solution. Thanks to its innovative, reusable cartridge system, any contact with chemicals and their waste is reduced to a minimum.
Hermetically sealed, each refi llable cartridge contains all reagents and chemicals needed for the measurement and cleaning process.
Measurements are tailored by the cartridge choice. The TCC cartridge measures the Total Cell Count of the microbial fl ora, while the ICC cartridge focuses on the Intact Cells Count.

This water monitoring instrument is the ideal choice for obtaining a complete microbiological overview of raw water, disinfection control, water treatment processes, line sanitation optimization and water quality assurance in fi lling lines.
The BactoSense Multi brochure is available for download from the bNovate website and provides a clear insight into how multi-point measurement works and the benefi ts it off ers.
