When planning rainwater treatment systems, the question often arises: full-flow or partial-flow treatment? Both approaches follow different strategies for treating rainwater runoff and must be selected specifically for the application in question. Whilst full-flow treatment involves purifying all the rainwater collected, partial-flow treatment treats only a defined proportion, with excess water being discharged via an overflow device.

The choice of the right solution depends on various factors, such as site size, pollution levels and purification performance requirements. HAURATON’s new information page offers sound guidance on this and explains when each approach is best used.
