Hynds Environmental

The Hynds Up-Flo Filter offers unrivalled performance in stormwater filtration. The system combines a patented upward flow path with a unique Drain Down system to achieve the highest possible removal efficiencies of fine sediments, nutrients, metals, oils, organics and bacteria. The system is designed to remove more than 90% Total Suspended Solids... (TSS) with a mean particle size of 20 microns (0.02mm). The Hynds Up-Flo Filter has recently been accepted by the Auckland Regional Council (ARC) as achieving 75% Total Suspended Solids (TSS) removal. The internal components of the Hynds Up-Flo Filter have been developed using Computational Fluid Dynamics (CFD) modeling and full-scale testing to maximise flow distribution while minimising short-circuiting through the filter media. This resulted in achieving the highest filtration rates available with minimal head loss requirements. Each individual filter module can be engineered to have an unprecedented treatment flow rate of up to 1.6 l/s or higher depending on the media combination and performance requirements. A small footprint, modular design and high flow rate distinguish the Hynds Up-Flo Filter's from conventional downflow and radial flow stormwater filtration devices. The resulting reduction in size of the concrete chamber means the complete installed system is more cost effective than conventional stormwater filters for the same flow rate. The Hynds Up-Flo Filter's multiple treatment capabilities - settling, screening and filtration - combined with simple installation and ease of maintenance make it the most effective and economical stormwater treatment system available. From a simple retrofit application to standard manhole configurations or even large vault systems, the Hynds Up-Flo Filter is the future of stormwater treatment.Read More
