Smart digital solution: Aquasuite® Anaerobic Controller providing long-term and more sustainable solution
Operational savings for water-intensive
No capital expenditure and no significant modifications to the plant
Reduced excess operational costs (€ 2mln annually) from lost biogas production, extra energy costs and the cost of reseeding the process with anaerobic sludge after washout
This was the situation facing our client which had recently extended its production plant with two new anaerobic reactors to treat effluent from pulp and paper operations. Royal HaskoningDHV was approached to provide operational support to help manage issues with the new reactors.
We calculated these issues were leading to an excess operational cost of more than €2 million annually – including from lost biogas production, extra energy costs and the cost of reseeding the process with anaerobic sludge after washout

Organic compound input assessed and smoothed
Our team identified that Aquasuite® Anaerobic Controller offered a long-term and more sustainable solution for our client because it autonomously optimises operations around the clock. This advanced process control software is based on our extensive domain and software knowledge and uses soft sensors, predictions and process monitoring to regulate the organic load.
The modular software can be quickly tailored to the client’s specific needs and then draws on output from existing instruments and data points. It requires no capital expenditure and no significant modifications to the plant, so its introduction does not interrupt ongoing operations. Equally, as soon as the software is in use, system optimisation starts, and performance improves.
Huge savings offered from low-threshold solution
“In practice, industry influent always has spikes and dips,” Robert added. “Where Aquasuite® makes a difference is that it takes signals from the control system and, using algorithms and predictions, regulates the pump speed based not on flow but on the required quantity of organic compound. The calculations are taken from existing data points and verified in the laboratory. It is very accurate.”This is a low threshold solution which can create a very big impact, offering potentially huge savings for businesses that operate on small profit margins. In this case, we anticipate annual opex savings of around €2 million. Similar impact has been replicated elsewhere - for example at a smaller food plant Aquasuite® Anaerobic Controller led to annual savings of around €1 million.
