PUMPS, VALVES & ACTUATORS
A BREATH OF FRESH AIR IN BREWING
An AirJet system from Landia is helping
Timothy Taylor’s brewery mix and aerate its balance tank to keep wastewater fresh
ollowing an intensive five-day survey of its wastewater treatment process, the highly renowned brewery, Timothy Taylor’s (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 wastewater treatment provider, Ogden Water, found that the pumps used for the brewery’s 45m3
F
balance tank were not providing enough agitation to adequately keep solids in suspension.
A long-lasting solution
“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 added: “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 and long-lasting solution.
“We’d previously used Landia’s pumps and mixers,” continued Ogden Water’s David 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 7.5m, to provide complete aeration
Berkovits commented: “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.”
Spring water
Today, Timothy Taylor’s brewery sits upon a particularly pure and consistent source of water (the Knowle Spring), that is the unique source for its beers – and key to why its much-loved ‘Boltmaker’ has been crowned Supreme Champion Beer of Great Britain at the CAMRA (Campaign for Real Ale) Great British Beer Festival. Water from the Knowle Spring has filtered over time through layers of sandstone and black rock, to create the special mineral qualities that marry perfectly with Timothy Taylor’s Golden Promise barley malt. This combination is the foundation of the complex flavour and subtlety of the brewery’s most popular beer, Landlord.
