BiAqua’s water treatment solution

The BiAqua solution is a bio-based technology that is able to create extremely low phosphate concentrations in water (below 1 ppb), one of the key strategies in tackling biofouling and bacterial growth in water systems preemptively. The BiAqua solution is also able to extract hazardous metals and other harmful substances from water (e.g. arsenic), even when present in extremely low quantities, resulting in pure water.

Uniquely, BiAqua offers a singular approach to solving the world's water pollution challenges. Our solution eradicates the primary causes of water pollution, like bacterial contamination and arsenic in water. While on the other hand it significantly increases the efficiency of water treatment systems by preventing reverse osmosis membrane biofouling and biofilm formation.

The most widespread applications for BiAqua water treatment technology are:

BiAqua PadEx systems

PadEx stands for Phosphate adsorber Exchanger. These adsorption systems have been specifically designed for the use with BiAqua’s bio-based adsorbent. Using our adsorbent to treat water with phosphate levels ranging between 0.1 and 25 ppm will result in extreme low levels of phosphate concentration (< 1 ppb). The PadEx system can be used in temperatures up to 60°C and with pH values ranging between 4 and 10. PadEx water treatment systems can also be equipped with a regeneration station that completely reactivates the adsorbent.

Don’t hesitate to contact us if you are interested in how our solution can help you with you water treatment challenges and can effectively reduce your operational costs. Our PadEx systems receive regular attention from organizations that are using RO membrane systems, organizations that are active in wastewater treatment, and organizations active in the horticulture sector.
