To suspend the solids from Deeside Cereals’ effluent, the Landia AirJet was soon put into operation. Comprising a 5.5kW Chopper Pump (invented by Landia in 1950) and a venturi nozzle, the low-energy AirJet can mix and aerate down to a water depth of approximately 7.5 metres, without the need for a compressed air supply.

Alistair Fielding from Watermark said: “It’s a simple setup; easy to install, and very effective.  Based on our preceding work with Landia, we had no hesitation in recommending them to Karl. We want our customers to benefit from equipment that not only provides the right solution but also offers the best possible value in total cost of ownership.”

Watermark had previously teamed up with Landia to help introduce a mixing system to handle wastewater at an expanding organic poultry producer in South Wales. Here, the AirJet eliminated the need for compressors, bottom-mounted diffusers and advanced controls.
