Cutting edge logic systems to serve your challenges

CREA® control platforms offer holistic process control solutions, built as a network of modular control blocks including synergies within, providing customized tools to empower you and your equipment to address your challenges: reliable and enhanced process performance, reducing operational costs, reducing environmental impact, and/or building resilience against climate change.  

The control modules are the cutting edge engine powering the CREA® platforms: using a combination of advanced logic tools tailored to each application (incl. Artificial Intelligence, Machine Learning, Fuzzy Logic) together with PIDs and modelling where relevant, and rule-based conditions that enables us to include any specific requirement from your site or your equipment. Together with enhanced monitoring and a transparent control tool fitted with editable configuration parameters, our control solutions will empower operations teams to stay in control of their process, control strategies and priorities. 

Beyond the control modules (the engine behind the scenes), the control platforms offer many process intelligence features, [Read more]

 

Modular control solutions for a holistic approach

We are all about process control. We are also all about delivering solutions fit for purpose: each of our process control modules are selected and adjusted to your site, and to enable synergies between control modules where relevant. In short, we have a very wide range of control modules on our reference sites, and continuously improve and expand depending on projects needs: so our portfolio is not a pick&mix off a catalogue. See below a list of our most widely implemented control module types, which we can customize for your particular application.

CATCHMENT

Flow and Energy management: adjusts the raw water abstraction from multiple sources to the real-time and forecasted demand. Prevents abrupt changes in water flow and takes into account the quality of each raw water source.

Early Warning system: includes predictive modelling to anticipate climate events and water quality issues, in order to support the best integral management strategy of the water supply system. Several versions with increasing involvement: modelling > decision-support > control. 

DRINKING WATER TREATMENT

Real time management of the processes & predictive features that allow an enhanced performance of treatment units and optimisation of chemical usage.

Provides an effective response to raw water quality variations and takes prescriptive actions to mitigate the formation of THMs/DBPs.

SUPPLY NETWORKS

Leak detection and non-revenue water control. Gains insights from the data generated across the distribution network to increase its hydraulic performance.

Advanced network managment: integral management of the elements of the distribution network to ensure the best water quality and mitigate the formation of THMs/DBPs, while also reducing process-related water losses and taking into account the energy efficiency strategy.

WASTEWATER

Provides and implements the most appropriate DO setpoint In real-time and N/DN process strategy to optimize nitrogen removal performance at minimum energy cost. 

Provides and implements the most appropriate DO setpoint in real-time to optimize organic matter removal performance at minimum energy cost. 

Based on real-time oxygen demand, it works hand-in-hand with N-control or C-control to achieve the desired DO at all times, by directly and efficiently controlling blowers (or other) and valves (where applicable) through a dynamic pressure control and a Most-Open-Valve strategy. 

Direct control of internal (liquor) recirculation pumps, to optimize nutrient removal at minimum energy cost. 

Direct control of sludge recirculation pumps, to reach the desired sludge management strategy at minimum energy cost. 

Direct control of chemical dosing pumps, to reach the desired PO4 level in the effluent with minimum chemical usage.

Direct control of chemical dosing pumps, to reach the desired nutrient removal performance with minimum chemical usage.

Direct control of chemical dosing pumps, to reach the desired treatment removal performance with minimum chemical usage.

Based on N removal performance and temperature, it adjusts WAS level (directly controlling pumps or via DSS), to ensure optimum sludge age. 

Based on time-of-use tariff, it optimizes the use of homogenization tanks to push treatment load towards more cost-effective timeframes. 

SLUDGE

Direct control of dewatering feeding pumps, polymer dosing pumps and (where applicable) decanter machine, to optimizes dewatering performance and polymer usage based on the desired strategy. 

Based on biogas production, storage status and  kWh cost, it defines the CHP operation strategy in real-time to maximises power production return via sale or on-site consumption based on consumption patterns. 

Direct control of dosing pumps (if any) and thickening equipment to increase process performance while minimizing chemicals usage, based on the desired strategy.  

Increased AD process robustness and reliability through real-time supervision of key process KPIs, to define real-time strategy to improve organic matter removal and biogas production. 

PROCESS INTELLIGENCE AND ANALYTICS

Based on calculations or power consumption records, provide data analytics and management of energy usage and cost. 

Advanced data analytics of monitoring equipment to continuously assess signal reliability, corrective actions as well as support instrumentation maintenance planning. Can be enhanced by coupling with CREAlab to include lab data in the assessment. 

Tracks and analyses energy consumption data and provides KPIs and warnings to other control modules to improve process control, detect early warning of equipment failure and deviations. 

Advanced data analytics including machine learning and soft sensors to further improve monitoring performance and reliability, and therefore process control performance and reliability.  

Enables the upload of off-line data (by hand or file upload) to enable data digitalization, comprehensive  process overview and deeper process intelligence, by joint data management and analytics of both online and offline data sources. 

Solutions are customized to suit your needs.
