Whitchurch-based pump manufacturer Landia has won an order from construction firm Galliford Try to supply its AirJet aerators for Southern Water’s Wastewater Treatment Works at Cowfold near Horsham in West Sussex.

Benefitting from a Landia chopper pump and an ejector system, the AirJets will be installed in above-ground 175 metre squared glass-lined-steel aeration tanks.

Here, the Landia aeration system will mix and aerate screened sewage and return activated sludge dosed with ferric chloride/sulphate with dissolved solids of 1 per cent or less.

Designed with a highly effective knife system that stops the aerator from becoming clogged by solids, the Landia AirJet requires no compressors, bottom-mounted diffusers, or advanced controls.

In addition to the municipal sewage industry, AirJet is used worldwide in industrial applications where solids need to kept in suspension.

This latest order for Landia follows the recent contract gains for its biogas digester mixing system with J Murphy and Sons for Yorkshire Water and for its chopper pumps with MWH Treatment for Severn Trent.
