Our systems produce water treatment agents on site from common resources

CIWI has developed electrochemical systems that enable water chemistry on‑site. Our technologies support the local production of iron‑based coagulants (FeCl₃, FeCl₂ and related iron hydroxides) as well as HCl and NaOH, allowing water treatment operators to generate the required chemistry directly at the facility. They only need salt, steel and electricity.

Smart Chemistry, Real Results

CIWI delivers measurable impact across every level of water treatment operations. From performance and cost savings to sustainability, safety, and supply security, our solution is designed to strengthen plants today while preparing them for tomorrow.

01 Performance

100% equivalent to conventional products, with potential improvements through application-specific, custom-made production.

02 Cost Savings

Operational costs are up to 60% lower than conventional chemicals, with additional upside depending on local chemical prices.

03 Sustainability

The carbon footprint is reduced by up to 75% from day one. By addressing Scope 3 emissions, we help our partners meet environmental targets.

04 Safety

In many cases, no chemical permits are required due to the low hazard classification. No risk of chemical burns, only mild skin irritation and limited corrosivity to certain metals.

05 Independence

No dependence on chemical prices or availability. Only steel and salt are required, widely available materials, with the flexibility to utilise circular resources such as brine streams.

06 Resilience

Enables months of autonomous operation instead of weeks, by eliminating up to 86% of transported mass.

Our on-site coagulant production system supports industries and utilities across drinking water, wastewater, desalination, and sludge treatment. One system, multiple applications, wherever metal salts are used.
