Combined chopper pump and ejector system offers an aeration solution for Timothy Taylor’s

24 February 2023

A survey undertaken by Ogden Water, found that the pumps used for Timothy Taylor’s brewery balance tank were not providing enough agitation to adequately keep solids in suspension in its wastewater treatment process.

“Solids had begun to accumulate,” explained Dr David Shepherd, Managing Director of Ogden Water. “The existing pumps were insufficient to fully mix and aerate the balance tank, so we set about finding a much better, long-lasting solution for the brewery.”

Nick Berkovits, Second Brewer at Timothy Taylor’s takes up the story: “Ogden Water’s survey showed that an upgrade to our aeration equipment would eliminate odours caused by solids not being sufficiently suspended and would also provide a much more consistent homogenous feed to our Dissolved Air Flotation (DAF) unit”.

Designed with a venturi nozzle from the Chopper Pump that Landia invented in 1950, the AirJet aeration system was recommended by Ogden Water as the best solution.

Simultaneously mixing and aerating, the Landia AirJet is an uncomplicated system that introduces air automatically to keep wastewater fresh; economically delivering dissolved oxygen at depths of up to 7.5m, to provide complete aeration

“It’s fair to say that before the installation of the Landia AirJet, the performance of our DAF was being compromised,” continued Berkovits. “We also had the time and cost of having to use chemicals to address odours. But now our wastewater treatment system is operating very well indeed”.
