Wastewater treatment plants form the crucial link between human activity and a healthy living environment. Whether it concerns an urban wastewater treatment plant or an industrial facility, the design and operation determine whether discharges comply with legislation and whether water streams can be reused.

Wastewater streams are constantly evolving. Urban growth or decline, changing industrial processes, stricter effluent requirements, and the increasing focus on Substances of Very High Concern (SVHCs) and Water Framework Directive (WFD) priority substances — including PFAS and micro‑pollutants such as pharmaceutical residues — call for a reassessment of existing treatment facilities. This may lead to expansion, optimisation, or even a complete redesign of installations.

Cantech supports you throughout this entire process:

• We map the composition and variations of wastewater streams.
• We provide advice on the most suitable treatment concepts and strategies.
• We develop designs for new installations or for the expansion or modification of existing facilities.

Our designs are not only technically robust, but also take into account permitting procedures, operational feasibility, and sustainability. This ensures that the chosen solution is future‑proof and fits within both the legal and practical context.

In addition to expertise in biological treatment processes, Cantech has a strong focus on advanced technologies such as membrane filtration and electrocoagulation (EC). These technologies make it possible to achieve very high effluent qualities and are well suited for applications where water reuse or the removal of complex substances is essential. Thanks to this expertise, we can offer innovative solutions that match the specific challenges of industrial and urban wastewater streams.

We do not view wastewater treatment merely as an end point, but as an opportunity to create new value. With a focus on the efficient use of energy and auxiliary materials, the recovery of resources, and the possibilities for water reuse, we support organisations in taking the step toward a circular water cycle.

Curious what this means for your organisation? Together, we provide advice and design the solution that best fits your wastewater streams and your ambitions for the future.
