Operating a wastewater treatment plant is costly. The complex processes consume a lot of energy and chemicals. By optimising the processes the operational costs can typically be reduced by 10-40%. At the same time the capacity can be increased. A 25% increase is quite achievable. Optimising the processes reduces the power consumption and need for water and chemicals. Reducing the amounts of chemicals also lowers the sludge production.
The cost of optimising the processes is recouped within a couple of years and in some cases even within a few months.
Rapid urban development and increased environmental awareness puts the treatment plants under increased pressure. The volume's to be treated increase and the capacity comes under pressure. In many areas the effects of climate change will further add to this.
Optimising a wastewater treatment plant requires mapping the system and a thorough understanding of the various processes. From inflow to outflow. It also requires careful monitoring of the processes with sensors which can detect the instantaneous conditions. The sensors provide the data necessary to model and optimise the individual phases of the process. This enables the operators to adjust the processes to reflect the inflow.
DHI technology and methods provide a fast track to reduce operational costs and increase capacity.
