**Process Data**
The water sector contains vast asset standards and process monitoring data sets. However, confidence in some sensor data can be limited, reducing its value, if assets are not correctly data mapped, routinely maintained and calibrated. There are also gaps with many sites that do not have comprehensive data on influent as well as settled sewage conditions needed to inform on process demand and operational control needs.

As a result, process evaluation surveys typically utilise a set of lab data derived from discrete or spot samples, which can miss key events and provide an incomplete picture of plant operation. Further still, conventional process evaluations can be limited to “static excel optimisation” limiting the ability to conduct a holistic evaluation of the works, increasing the risk of missed opportunities as well as leading to conservatism in design and operation. 

**Sensor development **
It is well understood that influent wastewater can be a harsh environment, containing rag, fats and oils. These contaminants can quickly reduce sensor accuracy impacting on the generated data quality that has historically limited the uptake of sensor application for routine measurement of wastewater influent characteristics. The material can also block conventional sampler hoses, with the potential to compromise reliable capture of a representative sample. 

In recent years sensors have become more reliable when incorporating effective air clean and focused quality controls, leveraged with access to the live data, via IoT applications. Now reliable digital data sets of the crude and settle sewage make-up can be gained, unlocking new insights into our understanding of wastewater treatment. This opens the potential to obtain granular rich data sets of the actual chemical make-up of the material entering works for treatment processing. 

**Process insights **
With the right level of temporary IoT enabled sensor data, a cost effective and disruptive approach to the conventional quantification of a works actual performance can now consider the application of sensors over manual time limited sampling programmes. With reliable sensor data, an assessment of the actual performance can be used to make informed challenges over the theoretical and technical design optioneering. It also assists to inform on the potential to defer or cease any capital investment, in favour of identified OPEX and operational control.

Please check out our case studies page as well as follow us on our LinkedIn profile for more details on how BI-Zen is helping its clients leverage more from their assets through its digital F&L service offerings.

This blog highlights the “digital approach” over the conventional manual data capture methodologies. Summarising why BI-Zen uses a combination of cloud analytical tools, process subject matter expertise and existing data, supplemented with multi-parameter IoT enabled instrumentation. To provide our clients with the right level of information to make informed decisions, leading to CAPEX and OPEX savings.

**Unseen Green House Gas from Wastewater Treatment**
As shared on our N2OInSite page, there is an unseen environmental cost to current wastewater treatment practices that is critical to today's climate crisis. Specifically the generation and release of Nitrous Oxide gas (N2O) that is about 300 times stronger than Carbon dioxide (CO2).

**The need for data now**
Evidence shows that N2O emissions often vary seasonally as well as spatially within tanks. To accurately baseline N2O emissions in a science-based manner, the Water Sector requires long term N2O monitoring data. However long term monitoring data is not required to being drawing process insights and mitigating N2O today.  For this we need high quality process data in order to draw informed technical insights – which factor in meaningful site-level information.

The solutions will not be found on a quest only to new emissions factors across different process types nor from a desk top analysis – they require high quality monitoring data which we can trust and a real understanding of site operation; how nitrification is controlled; management of liquors, flexibility, resilience and age of aeration systems. Whilst the solutions may be digital, black boxes, grey boxes, process and data driven models and more, we very much believe the understanding and knowledge has to be gathered collaboratively, believed in and acted on as rapidly as we can.

**BI-Zen's agile and innovative approach **
In order to play our part, BI-Zen has re-purposed the bouy with the objective to attach a number of sensors
onto it, which will be suspended within wastewater treatment plant aeration lanes. With the intension to gather un-matched 
real time data on the science behind the biological processes that treat the wastewater, while also gathering insights on 
the potential for increased green house gas generation linked to nitrous oxide emission pathways.

Follow us on LinkedIn and pending Blog updates as we look to share more details in the coming weeks.

While out for a family walk last weekend, our Solutions Director found a 2meter long bouy washed up on the beach in Dawlish Devon. Accordingly to locals it had been smashed up on the roacks for over a month. After a little encouragement, Alec got his two sons to help move the item off the beach for transport back to the BI-Zen workshop. Please click here to learn more on how we intend to fix a number of sensors onto the bouy and use it to gather data sets never seen before on wastewater treatment efficencies and green house gas nitrous oxide emission pathways.

One persons plastic waste, is another’s upcycled float to help improve wastewater treatment.

Hired digital real time wastewater load & process assessments are taking off here at BI-Zen!

In order to meet demand, as well as enhance our service offering within the process emissions space, the board recently approved the investment in more equipment. 

On top of the Optimiser builds, stands, IoT configuration, sensor configuration and programming, our team require branded van's that include bespoke kitting out in order to safely transport the equipment. Further still each van needs mobile lab equipment and a structure training programme, to ensure that we continue to provide trusted digital data to our clients.

As part of the recent focus we have also developed and tested the N2OInSites offering, that incorporates mobile equipment to assist in the understanding of Nitrous Oxide emission pathways within the wastewater treatment process.

Please follow our LinkedIn page where we communicate regaulr updates on progress and areas of interest

It's been a busy couple of weeks after more equipment has got through customs and the team have been able to assemble it.

Exciting news… we have added more units to our hired sensor based wastewater sampling asset base.

Here at BI-Zen we ensure our clients get the right sensor for the right location, coupled with a focused attention on data quality.

BI-Zen's mission is to provide quality data sets to inform on the optimum design and operation of wastewater treatment plants.

In order to achieve this we have developed an agile service offering using sensor based technology that can be efficiently deployed onto a wastewater treatment works, to capture information on the effluent make up. 

In addition to the management of data, its capture and communication and the cloud based visualisation, BI-Zen has devoted years to ensuring we provide quality data from its source. A significant element has been ensuring our deployed sensors are located in the right location and that they are calibrated and maintained for the duration of the survey period. An important part of this is ensuring the sensors are kept clean between each site visit.

The attached photos show some of early trials which didn't include the inbuilt cleaning applications that we have today... which did impact on the data quality. Years on we now have a system, coupled with extensive quality control, that ensures our un-matched granular data sets provide trusted insights into how plants are being loaded and performing. 

Without care, maintenance and adequate cleaning provision, wastewater sensors can start to foul up and potentially compromise the data quality and trust in what you are seeing from your site.

Quality wastewater effluent data starts with clean sensors

Yesterday Institution of Chemical Engineers (IChemE) hosted a technical seminar covering sustainable approaches to design for our water sector. The event was excellent, thanks to the coordination by Sarah Morris despite the traffic related delay of lunch – but we soldiered on.

Personally, I made the trip to hear first-hand from Joshua Williams and Keeley-Ann Kerr on their N2O monitoring experiences, and Dŵr Cymru Welsh Water strategic focus within this emerging area. In addition, the work with Hydrogen generation from wastewater by Richard Chamley (and the spare oxygen spin-off) was insightful and exciting. On top of learning more about Power & Water Electrocoagulation offering for Phosphorus removal at small PE sites, as an alternative to ferric dosing while also avoiding the consumption of alkalinity. An added benefit was that Mr Bungay happened to attend as well. 

Thank you to all that presented – it was a very good day and one that is evidencing that action is being taken and not just talked about. #sustainableengineering #nitrousoxide #wastewater #netzero
