Next week (24 February 2015), Salix will be exhibiting at Aqua Enviro’s Phosphorus Removal from Catchments event in Nottingham, showcasing BioHaven floating islands and other measures to improve water quality in river catchments.
Phosphorus is one of the most common parameters causing a watercourse to fail water quality standards set out under the Water Framework Directive. The one-day conference will explore techniques for reducing phosphorus discharges to catchments and innovative treatment solutions.
Made from recycled plastic, BioHavens are a new natural treatment technology that can help remove phosphorus and other harmful nutrients from wetland environments.
David Holland, Salix’s Technical Director, explains:
“Salix believes in finding sustainable solutions to wetland habitat restoration projects.
Each cubic meter of a BioHaven island has a 10,000 m2 surface area for beneficial bacteria to grow on, creating a biofilm of good bacteria that absorbs harmful nutrients and becomes the base of the freshwater food chain, attracting invertebrates and fish.
With an improved fishery, phosphorus can be moved up the trophic levels and out of the waterway as the fish are predated. BioHavens can also provide a great platform to host new phosphorus absorbing materials in the water.”
