SDS Aqua-Xchange™ is an engineered pollution control and enhanced filter media. It uses ionic exchange and filtration to remove soluble and solid pollutants from surface water runoff.
SDS Aqua-Xchange™ uses naturally occurring, loose granular materials that maximise the pollution adsorption process by enabling storm water to filter through the product’s large surface area. This prevents surcharging and allows enough contact time for the pollutants to be captured and ultimately retained for future disposal.
SDS Aqua-Xchange™ has been proven to capture and retain between 99.5% and 100% of copper and zinc toxic metal pollutants. So, it’s especially beneficial in areas with a high risk of metals pollution, and where the water treatment flow rate is greater, such as the road and rail network and industrial estates.
SDS Aqua-Xchange™ is also suitable for use in sites with a low to medium risk of pollution, such as residential developments, where it can be used to enhance the performance of other treatment devices, or when the additional removal of soluble metals is required.
SDS Aqua-Xchange™ can be installed as part of the new build construction process or retrofitted in established sites. It should be installed at a minimum depth of 250mm in order to achieve the residence time and product interaction that will guarantee the published performance levels.
The material is supplied in 1 cubic metre bags and can be deployed in a number of storm water treatment applications including filter drains, dry swales, bio-remediation devices, infiltration basins and catch pits, and with or without attenuation.
