Following an intensive five-day survey of its wastewater treatment process, renowned brewery Timothy Taylor’s of West Yorkshire, England, (family-owned since its founding in 1858) has upgraded its aeration process by introducing the AirJet system from Landia.

The survey — which was conducted by leading wastewater treatment provider, Ogden Water — found that the pumps used for the brewery’s 45-cubic-meter balance tank were not providing enough agitation to adequately keep solids in suspension.

“Solids had begun to accumulate,” says 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 added that “Ogden Water’s rigorous survey showed that an upgrade to superior aeration equipment would eliminate odors caused by solids not being sufficiently suspended, and also provide a much more consistent homogenous feed to our 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 a good and long-lasting solution.

“We’d previously used Landia’s pumps and mixers,” says Shepherd. “They are extremely effective, as well as being easy to maintain. And with a typical lifetime of at least 15-20 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 7.5 meters 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," says Berkovitz. "We also had the time and cost of having to use chemicals to address odors. 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.”
