New poultry wastewater installation by Watermark Projects and Landia

Watermark Projects 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 dissolved air flotation (DAF) as part of their design and build service, Landia’s AirJet kept the balance tank aerated, ensuring that solids were kept in suspension.
Comprising a Landia Chopper Pump and a venturi nozzle (ejector) that sucks in air and 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.”
He added: “Together with our DAF system, which is built in-house, Landia’s AirJet plays an important part in the help we are giving our poultry customer in reducing their environmental impact – significantly reducing their operational costs, as well as ensuring that they achieve local discharge consent.”
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.
This latest work for Landia follows the recent successful installation of its submersible Chopper Pump for the handling of wastewater at a chicken processing plant in Scotland.
Watermark Projects is part of leading engineering services company, W.A Cooke & Sons.
