Chemical Innovation for Water Industries

CIWI creates…

Water treatment chemicals on-site with fewer resources, less complexity, greater safety and sustainability.

How it works.

  • We replace traditional metals salts which are essential for every kind of water-treatment.

    Our product can be used in drinking water, municipal wastewater, and industrial water treatment.

  • We’re providing technology in a containerized system that produces these custom made water-treatment agents on site.

    It combines iron electrolysis with bipolar membranes and consumes only steel, salt, and electricity.

  • Through quality control, iron chemistry expertise and operational support we’re providing reliability.

    This way, our customers can focus on their core activities.

Benefits

Lower operational costs

Reducing the need for pH control chemicals, lower polymer consumption, and potentially lower water and sludge treatment costs.

Improved performance

CIWI can create a pre-hydrolyzed metal salt equivalent with 10% higher removal efficiency than conventional metal salts.

Higher resilience

Reducing supply chain dependency by 85%, increasing storage capacity by a factor of 8, and reducing transport needs by the same factor, making water treatment more resilient and less dependent on global events.

Better governance

Reducing salt intrusion by up to 50%, improving compliance with discharge standards, and enhancing on-site safety by eliminating the need for strong acid metal salt storage.

Improved sustainability

A 50% reduction in carbon footprint from day one, with the potential to reach 100% in the future, while also reducing resource consumption by up to 85%

Integration Ease

  • Compact Design

    Easy to integrate into existing infrastructure. The system fits within a single container and can be installed wherever metal salts are used.

  • Adaptable Production

    Flexible to adjust to changing needs. A single design enables the production of custom agents by adjusting settings to meet local requirements.

  • Energy Efficient

    Consumes energy equivalent to one or two EV charging stations.

  • Simple maintanance

    Less complex procedures and lower operational burden. Metal plates, the consumables, are easily replaced once or twice a month.

At the forefront of Water-treatment Agents

  • Pilots

    We are currently conducting several pilot projects to evaluate our product. In the most comprehensive pilot, we are collaborating with Brabant Water to test and further refine our product.

  • Research

    At our research lab, we are actively testing and further developing our product. Through this process, we have gained extensive expertise in the field of iron-based chemicals.

  • Publications and awards

    In the last few years our researched has been published en we won awards with our innovative technology. Want to read more about this? Go to our blog!

Due to climate change, water scarcity is becoming an increasingly serious issue. This creates an urgent need for more effective and efficient wastewater treatment. Water treatment chemicals are essential to this process. As a result, global demand for these chemicals is expected to double within the next 10 years.

Additionally, water reuse and resource recovery—such as phosphate harvesting—will further drive the need for treatment chemicals, supporting the development of circular water systems. To facilitate these processes in the most effective way, CIWI provides water treatment chemicals directly on-site, contributing to a more efficient and sustainable water treatment process.
