Following an intensive five-day survey of its wastewater treatment process, Timothy Taylor’s has upgraded its aeration process by introducing the AirJet system from Landia.
The survey, which was conducted by wastewater treatment provider Ogden Water, found that the pumps used for the brewery’s 45 sq m balance tank were not providing enough agitation to adequately keep solids in suspension.
“Solids had begun to accumulate,” said 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 Timothy Taylor’s a much better, long-lasting solution.”
Nick Berkovits, second brewer at Timothy Taylor’s, said: “Ogden Water’s rigorous survey showed that an upgrade to superior aeration equipment would eliminate odours caused by solids not being sufficiently suspended, and also provide a much more consistent homogenous feed to our DAF (Dissolved Air Flotation) 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 long-lasting solution.
“We’d previously used Landia’s pumps and mixers,” said David. “They are extremely effective, as well as being easy to maintain, and, with a typical lifetime of at least 15 to 20 years, are a very sound, peace of mind investment for our customers.”
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.
Nick said: “It’s fair to say that before the installation of the Landia AirJet, the performance of our DAF was being compromised. We also had the time and cost of having to use chemicals to address odours.
“But now, through the expert advice we’ve received from Ogden Water, and the success of what is a first-class aeration system from Landia, our wastewater treatment system is operating very well indeed.”
