Additional Information

Brand & Trade Names

  • Downstream Defender® Advanced Hydrodynamic Vortex Separator The Downstream Defender® is an advanced hydrodynamic separator designed to remove sediment, floatables and pollutants from stormwater. The Downstream Defender® provides greater pollutant removal and retention in a smaller footprint compared to conventional gravity or simple swirl-type devices. Flow modifying components create a stable vortex flow regime that is ideal for solids / liquid separation and preventing re-entrainment, with full retention of all captured sediment and floatables over a wide range of flow rates.
  • DynaDisc Filter The DynaDiscT is a microscreen consisting of multiple filter discs. The reliability of the DynaDiscT seals and durability of the filter fabrics allows the system to be used in a wide range of applications. Its patented filtrate separation system guarantees performance. For enhanced filtration efficiency the DynaDiscT can be fitted with a patented device to separate the filtrate into a pre-filtrate and a final filtrate. This option offers a filtration efficiency greater than that which can be achieved by any other disc type microscreen. The DynaDiscT is available as a freestanding tank or for stallation into a concrete tank.
  • DynaSand® Filter Filtration through a bed of sand is a cost-effective way of removing suspended solids and other impurities in water treatment and wastewater purification. DynaSand® is a continuously operating sand filter. The sand is cleaned by means of an internal washing system, eliminating the need for wash water storage tanks, backwash pumps and collecting tanks. With low head loss, low energy consumption and low maintenance the reliability and effectiveness of the DynaSand® is clearly demonstrated by the more than 18,000 units in operation worldwide today. The DynaSand® Filter is available as a freestanding unit or as modules for installation into a concrete basin.
  • Grit King® Process The Grit King® Process separates, cleans and dewaters grit from raw sewage and other liquids prior to delivering the classified grit to a skip ready for disposal. The Grit King® Process consists of a Grit King® Hydrodynamic Separator with backwashing system using air or water, a grit removal system (pump or gravity), a Grit-CleanseT or Grit Classifier and all connecting pipework. The Grit King® Separator requires no external power source, as it uses the inherent energy of the influent with a head loss of typically less than 150 mm. Performance comparisons have shown the Grit King® Process to be up to 15 times as effective as conventional grit removal technologies. Ideal for retrofits and new plants, the Grit King® has low lifetime operational costs and can be installed as a freestanding vessel or internals fitted into a concrete chamber.
  • Heliscreen® - Powered CSO Screen The Heliscreen® is a compact, powered screening system with the ability to operate under surcharged conditions.

The Heliscreen® also has the unique ability to operate under submerged conditions. Compact and adaptable, the Heliscreen® is ideal for installation at new or existing CSO facilities where a low maintenance system is required but site constraints, hydraulic levels and/or chamber dimensions preclude the use of Hydro International's non-powered, self-cleansing screens.
  • Hi-OxTM Ultra-Fine Bubble Panel Aeration System The most energy intensive operation in any activated sludge plant is associated with the requirements for mixing and aeration. The HiOxT ultra-fine bubble diffuser reduces that energy requirement by increasing the transfer efficiency by 20% to 30%. This is achieved by producing smaller bubbles and having high floor coverage, giving a low flux rate. This higher transfer efficiency translates to reduced air demand and thereby to reduced operating costs. Applications . High-rate aeration processes. . Activated sludge. . Membrane bioreactor.
  • Hydro Filterra® Stormwater Bioretention Filtration System The Hydro Filterra® Bioretention System harnesses the power of nature to capture, cycle and immobilize stormwater pollutants to treat urban runoff.

An award winning combination that delivers a low maintenance CSO solution and resulting in low whole-life costs.
  • Hydro-SludgeTM Screen The Hydro-SludgeT Screen is an in-line pressurised device that screens sludge and dewaters the screenings in one operation. The enclosed system eliminates odour problems. No washwater is required for separation. There are two units available; the SludgeScreenT and the SludgeScreenT Compact. Whilst both models can be used on wastewater treatment plants, the SludgeScreenT Compact is suited to very confined spaces.
  • Hydro-Static® Screen The Hydro-Static® Screen is a cost-effective, non-powered screen for the control of gross solids and floatables in combined sewer systems. Designed to complement Hydro International's wide range of CSO Screening products, the Hydro-Static® Screen provides screening better than 6 mm in two directions. The Hydro-Static® Screen intercepts and retains floatables, aesthetically offensive material and gross solids over a wide range of flows. The collected material is then returned to the combined sewer after the storm event. An emergency overflow weir is incorporated into the screen should the peak design flow be exceeded. The Hydro-Static® Screen is available as either an Up Flow Screen or a weirmounted Through Flow Screen.
  • Lamella Plate Clarifier The Lamella separator is the world leader in sedimentation technology. Lamella Separators can reduce space requirements by up to 90% compared with a settling pond. With this system every square metre of floor or ground area provides up to 10 m2 of settling area. The separator incorporates a patented flow control system, a breakthrough in modern plate separator design. The flow control system uses the clarified liquid as the control medium and ensures that the flow is distributed uniformly across the plate assembly. The Lamella Separator is supplied as a complete, easy-to-install unit or as a plate pack assembly for installation into either a concrete or steel tank.
  • Storm King® Overflow with Swirl-CleanseTM Screen The Storm King® with Swirl-CleanseT Screen is an advanced hydrodynamic vortex separator that incorporates a unique, self-cleansing, non-powered screening device. Designed as the ultimate CSO treatment device, the Storm King® with Swirl-CleanseT Screen does it all, from the screening and removal of gross solids and floatables greater than 6 mm in two directions to the removal of sediments, settleable solids and associated pollutants (eg. TSS, BOD and COD). The Storm King® with Swirl-CleanseT Screen is ideal for satellite treatment within the collection system. Installing units at the source reduces the need for increasing conveyance capacity and makes this device an economically viable solution.
  • StormBank® Rainwater Harvester The StormBank® Rainwater Harvesting system is a simple filtration and storage system that can replace the use of expensively treated mains water with rainwater for toilet flushing, garden and outdoor use.
