Landia’s GasMix System Installed at Cory’s First Anaerobic Digestion Plant

Landia’s acclaimed GasMix system is at the heart of the new biogas making process using anaerobic-digestion, at Cory Environmental. Cory, with over 40 sites are one of the UK's leading recycling, waste management and energy recovery companies. March 2014: Cory has unveiled its first anaerobic digestion facility, which will produce renewable energy to power local homes.

Cory's first digester in Weston-Super-Mare can handle 12,000 tonnes of food waste per year and generates up to 500kw of energy per hour for on-site use and export to the National Grid. 7,500 tonnes of this amount is part of a seven-year waste treatment contract with the North Somerset Council.

Alistair Holl, Cory’s Director of Resource Management, said:

“We are very proud of our first AD facility, for which our team were main contractors, as well as plant and site designers, achieving energy production just 18 months after planning consent was gained. This includes us recognising the importance of a highly effective and ultra-reliable mixing system, which is why we’ve chosen Landia’s GasMix. It mixes the digester throughout at a consistent temperature, which will optimise our gas generation”.

He added:

“GasMix is mounted externally on the digester so routine maintenance can be carried out with no interruptions, and from our past experience with Landia, we also have peace of mind in the back up service that they provide”.

 

For over a decade, Landia’s Chopper Pumps have been installed at other Cory sites – and at Weston-Super-Mare, they are also in use in eight other process and storage tanks, where they perform a combination of process mixing and transfer functions.

Paul Davies, Landia’s UK & Eire Sales Manager commented:

“Our relationship with Cory has grown steadily over the years as we’ve worked together to adapt the best possible pumping and aeration solutions for their wastewater needs. We are very pleased to see the faith placed in us and our equipment, with our GasMix system set to play a long-term role in the success of this impressive new facility”.
Alistair Holl continued: “Initially, we’ll be producing enough energy to power around 1,000 homes, and will soon be working towards the second phase of the development, which will see an upgrade of the plant to a minimum of 1MW. This will double the volume of our green energy generation at Weston-super-Mare”.

Comprising three 18.5kW chopper pumps and a self-aspirating system that reduces solids to produce more methane in a much shorter time period, LandiaGasMix (designed specifically for AD/biogas) has no mechanical equipment inside the digester.

Simple to regulate, GasMix also offers significant energy savings because it only has to run for a maximum of 30 per cent of the day.

What Others Are Saying About Landia's GasMix Digester Tank Mixing System:

Landia GasMix system installed at California AD facility

(July 2017) ES Engineering of Irvine, California, has installed a GasMix system from Denmark-based Landia at a food waste-to-energy facility in Chino, California, to help boost gas production from the facility's two anaerobic digesters. Landia chopper pumps were previously installed at the site by ES Engineering.

When ES Engineering took over the Chino plant, the digesters were outfitted with top-mounted propeller mixers, but the amount of mixing achieved was insufficient, according to Plant Manager Alfredo Ferrin.

[So, they called in Landia who installed their full mixing system.]

The Landia chopper pump is designed with an external chopping system that is separate from the pump casing and impeller to prevent clogging. Nonetheless, it can be an important part of the Landia GasMix system. All chopping is done before the liquid enters the pump housing, reducing wear on the pump casing, impeller, and sealing system.

All Landia GasMix system mechanical components are externally mounted and use a combination of biogas and liquid recirculation for mixing. This is intended to allow inspection and maintenance to be performed without entering or opening the digester.

Servicing of the Landia GasMix system can be completed while the biogas production continues uninterrupted. via Mixing California AD facility

Anaerobic Digestion Plant Operation 8 Years-On with Landia's GasMix

The GreenGas plant in County Limerick, Ireland's first farm-scale AD (Anaerobic Digestion/Biogas) plant, is approaching its eighth year of operation, but the 24/7 attention to detail has never been more focused.

Despite close collaboration with a German engineering firm (Kreig and Fischer), they chose to work directly with equipment suppliers, including Landia, which supplied mixing equipment.

Kirk supplied our first digester (1,000m3), with Gary Little recommending Landia for its mixing systems, introducing us to the late Hugh Vaughan.

“Lifetime cost was a very big selling point for us, as was a relationship with companies who were proud of their work and prepared to roll up their sleeves and make things happen”.

At first, Landia’s GasMix didn’t appear to be achieving the results that had been forecast, but this was soon rectified. via Anaerobic Digestion Plant Operation 8 Years-On LandiaGasMix
