Watermark Projects & Landia: Wastewater installations

Watermark Projects (part of leading engineering services company, W.A Cooke & Sons) has introduced a Landia mixing system to help handle wastewater at an expanding organic poultry producer in South Wales. 

Prior to the effluent being treated by Watermark Projects’ bespoke DAF (Dissolved Air Flotation) as part of their design and build service, Landia’s AirJet will keep the balance tank aerated, ensuring that solids are kept in suspension. 

Comprising a Landia Chopper Pump and a venturi nozzle (ejector) that sucks in air (and therefore oxygen) and then mixes the wastewater, the AirJet eliminates the need for compressors, bottom-mounted diffusers and advanced controls. 

Alistair Fielding, Water Projects Manager for Watermark Projects, said: “Landia equipment is always very reliable; easy to install and maintain. We know we can depend on it to deal with the peaks and troughs of this application, including after clean-down in the poultry processing plant when the wastewater is more contaminated. Working on the specification with Landia was very straightforward. They are always quick to respond”. 

The Landia MPTKR-I Chopper Pump for the externally-mounted AirJet, is a soft-start, 1500rpm, 7.5kW unit, mixing and aerating screened poultry effluent with a pH of 4-8 in an above-ground 300m3 steel balance tank.
