In some situations, it is desirable—or even necessary—to reduce discharges to zero. Zero Liquid Discharge (ZLD) is an approach in which all wastewater is treated and reused, ensuring that no liquid residual streams are released into the environment. In addition to maximising water recovery, ZLD also creates opportunities to recover valuable resources from the concentrate.
Zero Liquid Discharge (ZLD)
Evolving challenges
The increasing pressure on water resources and the tightening of discharge requirements are making ZLD solutions increasingly relevant. Especially in industries where water is scarce or where emissions of specific substances are no longer acceptable, ZLD can offer a viable pathway. This requires carefully designed systems that are both technically reliable and economically feasible.
Advisory and design
Cantech supports organisations in exploring and developing Zero Liquid Discharge (ZLD) concepts.
- We analyse water flows and identify which technologies are required to achieve complete recovery.
- We provide guidance on the feasibility and strategic added value of ZLD within the specific context of your company.
- We design installations and process modifications that minimise discharges and maximise reuse.
Our specialisations
We combine knowledge of classical treatment methods with expertise in modern and innovative solutions. This enables us to deliver tailored designs focused on reliability, energy efficiency, and seamless integration with existing processes. In doing so, we make ZLD not just an ambition, but a practical and achievable solution.
Sustainability and the future
Zero Liquid Discharge fits seamlessly within the transition to a circular economy: water streams are fully utilised, resources are recovered, and environmental impact is minimised. As a result, ZLD not only addresses discharge requirements but also creates an opportunity to operate sustainably and future‑proof.
Curious what this could mean for your organisation? Together, we advise and design the ZLD solution that best fits your water streams and ambitions.
