Calamities or underperformance at industrial wastewater treatment plants. This can result in incidental operational costs that can be extremely high and is at odds with the continuous pressure to reduce costs and become more efficient and effective. We see unnecessary cost as a result of high energy and/or chemicals consumption or suboptimal biogas production, all as a result of suboptimal operation.
More stingent discharge standards
The second operation risk is (non)compliance: to meet the applicable environmental and discharge standards. Here we have on the one hand standards that get more stringent every year and on the other hand the fluctuations that industrial wastewater is known for; industrial wastewater, when compared to municipal wastewater, has a big variety in flow and composition (even more so after primary processes are optimised!), making its treatment quite a challenge. Non-compliance can lead to fines, negative publicity or even put the whole production at risk.
Limited in-house knowhow
Thirdly, we must acknowledge that wastewater treatment is a secondary process. This often means that Industries only have a couple of in-house experts and operators with the proper knowledge and experience to run a wastewater treatment plant. Losing one or two key people can already lead to substantial problems, simply because their knowledge leaves the organisation with them.
