city. In total, the 160HP of course used up a huge amount of resource. The blower is 100HP, but is only needed 25 per cent of the time – and the mixers at just nine HP each (36HP in total) are in comparison, extremely efficient and very effective indeed”.
Bill Eoff added:“Running 24/7, for over five years with no major issues, the Landia mixers have been a great investment.We pull them up every six months to change the oil and grease them – and that’s basically all the maintenance they need.We’re very happy with them.We knowthat there will inevitablywe somewear and tear with shims and seals that over time need to be replaced, but overall, they are very easy to maintain. In five years,we’ve spent less than $3,000 on spares. This is aworld of difference compared to the rotors, which no longer provide value. Aswell as the help we’ve had from Instrument & Supply, Landia
have been very supportive throughout, from start-up to supervising our first service – and much more with additional advice and training. Theywere and still are determined to help us succeed”.
‘Supports the greater Community’
Chris Enloe concluded:“Huntsville did not have the option to build a new plant, but with real determination they nowhave the tools to effectively operate the plant within permit – without breaking the bank. This supports the greater community byworking together with its neighbors, including the food manufacturer, which is very important to the local economy. The result demonstrates just howgood the Landia solution fits within the many constraints that are in Huntsville. Rightly so, the team at the wastewater treatment plant are very proud of theirwork”.
The Landiamixers have been
ruinning at Huntsville for 5 years, without anymajor issues.
Historic site of Saxon Kings benefits from AUMA Actuator Installation
A sewage treatment works that sits on an island in themiddle of the River Thames, which was once the site of an important palace of the Saxon Kings, is now home to a new automated AUMA actuator installation.
ThamesWater’s OldWindsor Sewage TreatmentWorks is located on a low gravel peninsula known as HamIsland on the Berkshire bank of the Thames at Old Windsor. AUMA Actuators Limited was contracted to install a remote controlled AUMA SA10.2 actuator to automate the opening and closure of a hand wheel operated penstock. The installation also features an indicator light system, which is fitted to the actuator’s cover tube and enables operators to view the actuator status at distance on site.
Colin Borrows, OperationsManager, AUMA Actuators Limited, says: “Thames Water wanted to automate the penstock operation on the bund at the Old Windsor Sewage TreatmentWorks using an actuator. The AUMA SA10.2 is perfect for this.With the addition of our unique
24
indicator light systemThames Water’s onsite team can now see the operational status of the penstock froma distance, saving time and the need to check the valve position in- person.
“The OldWindsor site is steeped in history so it’s great to think that our solutions are providing peace ofmind in a place that was once the seat of Saxon royalty.”
