Your challenges

Reduce Carbon Footprint
Conventional flocculation systems rely on motors, mixers, and large infrastructure that increase energy use and operational emissions. ILCA® offers a low-energy, passive alternative that helps reduce overall carbon footprint.

 

Resilience to Climate Change
Variability in raw water quality, driven by climate-related events, can impact treatment performance. ILCA® provides stable and flexible floc formation across a wide range of surface waters, supporting operational resilience.

 

Optimize Totex
With no moving parts, simplified design, and minimal maintenance, ILCA® significantly lowers both capital and operating costs, helping utilities optimise total expenditure over the system's life cycle.

How does it work ?

ILCA® is designed to follow the point of coagulant dosing, whether through a static mixer or overflow weir, and provides the controlled flocculation conditions required for effective membrane pre-treatment. Instead of relying on large tanks or long residence times, ILCA® uses a compact chamber fitted with removable plates that generate the appropriate shear (G-value) and contact time (T-value) to form small, stable microflocs. These flocs are ideal for removal by downstream advanced membranes.

There are no mechanical mixers, motors, or sedimentation stages involved. The process is entirely passive, in-line, and optimized to balance performance, footprint, and sustainability.

Our positive impact

ILCA® offers a simplified and effective approach to flocculation that brings performance, sustainability, and cost advantages across a range of applications.

Compact and low-maintenance

ILCA® eliminates the need for large tanks or mechanical mixers. Its passive, in-line configuration saves space and reduces maintenance complexity—ideal for both retrofits and new installations.

No moving parts, low energy use

With no stirrers or mechanical mixing devices, ILCA® significantly lowers energy requirements in the flocculation stage, reducing both operational costs and environmental impact.

Controlled G/T values for ideal microflocs

Removable internal plates create defined G-values (shear rate) and contact time (T), forming microflocs well suited for membrane filtration. This improves water quality, reduces membrane fouling, and supports stable long-term operation.

Lower carbon footprint

By simplifying infrastructure and minimising energy and maintenance needs, ILCA® supports utilities in reducing their overall environmental impact.
