Conventional flow and load studies are widely used to understand the treatment demands of a site, and assess headroom availability.  The process for completing these studies is well established, but the standard approach provides limited granularity and is susceptible to delays or errors during laboratory analysis

Problem

BI-ZEN provide flow and load surveys using instruments connected to live dashboards, with the findings recorded in a formal report.  
The equipment can be deployed rapidly, monitored remotely and requires minimal intervention from site staff during the monitoring period. 

Sampling frequency is easily adjusted.  Each reading is associated with a time stamp, allowing detailed analysis of fluctuations to ensure that collected data gives an accurate picture of your site’s performance and capacity.


Solution

- Rapid results with the right focus to implement change and immediately monitor the benefits.
- Significant ROI
- Unmatched site-specific process insights
- Strategically valuable toolkit to meet the AMP challenges

Digital Flow and Loads

PST’s offer efficient and sustainable treatment when maintained in a steady state. They can also become an unnoticed dumping ground for sludge build up within an effluent stream, particularly if there are issues elsewhere on site.  The impact on process efficiency and compliance, as well as the increased odour potential, can easily be missed.

As soon as the sludge settles as a blanket within the PST, it will start to hydrolyse, releasing volatile solids in a soluble form, and allowing conversion of nitrogen into ammonia. In turn, this results in a reduction in PST performance and an increase in downstream energy and chemical costs.


BI-ZEN’s mobile instrument rigs can be deployed to site rapidly, requiring only a power supply to get up and running.

Our PST dashboard reports the impact of high sludge blankets in financial terms.  With £s in front of their eyes, site operational staff are able to make informed changes to site desludge schedules.

BI-ZEN’s process experts will work in collaboration with your site team to understand the optimal blanket level for the site.  Increasing the knowledge of the operators is a key outcome of this work, and ensures that the project leads to lasting changes in operational behaviour. 


- Enhanced visibility of PST performance
- Improved granularity, quality, and consistency of data
- Real time intelligence
- Lower costs of assessment than conventional methods

Primary Tank Optimisation

The treatment standard expected at a wastewater site is constantly moving higher.  Maintaining compliance in the face of unpredictable incoming loads, problematic assets and tight budgets is a real challenge.

Operational staff often know which sites are likely to have problems, but it’s hard to know when the issue will arise.  Sites can’t be manned 24 hours a day, compliance samples can be taken at any time, and sometimes you just need a hand solving the cause of the problems.


BI-ZEN’s mobile instrument rigs can be deployed to site rapidly, requiring only a power supply to get up and running.

Once installed, the rigs constantly monitor the effectiveness of your treatment process, sending data back in real-time to dashboards that can be accessed from any computer with an internet connection.

Alarms can be configured to alert your operational team to compliance issues, allowing them to get to site rapidly, solve the immediate issue and investigate the cause.


- Faster delivery in data provision, than conventional methods
- Real time informed understanding of the end to end process
- Greater visibility of trends, spikes, diurnal patterns
- Improved decision making, when evidencing a step-change in asset performance

Compliance Recovery

The efficiency of the pumping system can be easily understood. Aeration efficiency is also simple in terms of kWh/m3 sewage treated, however, the true measure of efficiency is measured in kgO2/kWh and % per meter which has previously not been measured.
Generally for diffused air systems the efficiency of the diffusers will deteriorate over the asset life of the diffuser. Measuring this efficiency would allow for management of any diffuser maintenance or replacement programme and the effects on efficiency to be understood.

In addition, Anoxic zone performance is usually not measured but is a process offering >20% energy efficiencies.


With just one Optimiser, deployed within the settled sewage feed to your ASP, as well as provision of site DO, MLSS concentration, and relevant flows, we have the tools to generate a baseline efficiency for your site. Outputs include a real time oxygen demand as well as Anoxic (free treatment) performance.

When applied to a batch of ASP plants, the Optimiser could be efficiently moved from site to site. Generating efficiency ranking of your asset base, and enabling considered decisions to be made on which sites would benefit most from diffuser maintenance, or simple soft measures like acid injection / bump scout regimes, as well as anoxic zone management.


- Informed Aeration Efficiency Benchmarking
- Performance testing of new ASP assets
- Asset Management Tool to inform on diffuser maintenance or replacement programme
- Actual performance measurement of Anoxic tank performance with and without mixers in service. 
- Granular settled sewage loading data

Activated Sludge Optimisation

The UK water sector is likely to be subject to significant legislative change, given the emerging data linked to Process Emissions that include Nitrous oxide, the change will be rapid.

How water providers approach the monitoring and collection of their process emissions data is not yet regulated, nor guidelines are set. 

Most studies will require long term (> 1 year) of monitoring per site.

N2OInsites offering is an effective short two week “screening” exercise, to gather baseline data sets.

Bi-Zen install functional, high quality instrumentation at wastewater treatment sites for initial N2O screening campaigns, to provide first insights into N2O production and the emission of their clients treatment works. 

This will enable companies to prioritise spend, identify potential site-level triggers and develop an understanding of N2O emissions and mitigation potential across their asset base.

The solution is agile and actionable.

N2O InSites campaigns are not intended to replace the global demand for long term baseline monitoring, it is intended to support site-level action, to provide high quality campaign data that can be trusted and used for validation, and it will provide real time insights into N2O production and emission across clients largest treatment assets.
