Usually, the wastewater undergoes a physicochemical pre-treatment, followed by a biological post-treatment in which micro-organisms work together to remove the remaining pollution in the wastewater. This biological purification can be seen as a living system that requires the necessary attention and expertise to function optimally.
Find “The sweet spot”
Wastewater treatment is a cost for a company that should not be underestimated. Performing the process at a minimum cost without compromising the discharge standard is therefore a must for every company. But wastewater treatment is a profession in its own right, which is not at all part of the core business of most companies with a water treatment system. Support from experts is therefore recommended to relieve companies of their worries and to work cost-efficiently.
Simple interventions, major consequences
Significant savings can already be achieved with relatively simple interventions, in the areas of energy consumption and chemicals and for general maintenance. For example, you can drastically reduce the energy required for the aeration of a biological treatment plant by simply optimizing the control of the oxygen level in the plant. Overdose of chemicals during the physicochemical pre-treatment also occurs frequently and can be greatly reduced with simple experiments.
Turn wastewater into a source of income
You can even go a step further and consider wastewater as a source of income. Wastewater contains organic carbon, nutrients, and especially… water. From a technological point of view, it is possible to recover these raw materials from wastewater and upgrade them to products with a usable quality.
For example, phosphorus is already recovered from wastewater in the form of struvite. This struvite is sold as a phosphate fertilizer and is an alternative to the phosphate from a fossil origin. And we are only at the beginning of the possibilities: there is still a whole range of new alternative recovery technologies in the pipeline.
