Kelda Water awarded our Biogas company with the contract to replace an old biogas dome in Aberdeen that was originally installed around the turn of the millennium. This involved removal and disposal of the existing 1500 cubic metre dome, and the design, fabrication and installation of a brand new replacement, including new fans and associated hardware. AJ Tensile Biogas Systems Ltd engineered and managed the project, with sister companies AJ Tensile Manufacturing Ltd and AJ Tensile Tension Systems Ltd handling the fabrication and installation respectively. The removal and clean-up of the old biogas dome took three men three days and the installation of the new dome took three men five days, with all works completed on time and within budget.

Welsh Water acquires Cardiff food waste recycling plant

Water and Wastewater Treatment Online reports that Welsh Water Infrastructure – a part of the not-for-profit Glas Cymru group which includes Dŵr Cymru Welsh Water – has taken ownership of a food waste anaerobic digestion (AD) and composting plant in Cardiff as part of its plans to further develop its waste and renewable energy business. AJ Tensile Biogas Systems designed, project managed and installed the fabric digester roofs, which were manufactured by sister company AJ Tensile Manufacturing Ltd. 

The plant was previously owned by Kelda Water Services, is located within the company’s Cardiff Wastewater Treatment Works in Tremorfa, and already supplies the site with renewable energy. With this investment in food waste digestion on the site, around 50% of the energy used by Cardiff Wastewater Treatment Works is now generated by the company through sustainable, renewable generation.

The major advantage of anaerobic digestion is that methane, which is produced naturally when the food waste breaks down, is captured and used to generate renewable electricity and heat rather than allowing it to escape to the atmosphere from landfill sites.

This latest development comes as Welsh Water continues to expand its use of renewable sources across wind, solar, and anaerobic digestion facilities. Around 23% of the energy currently used by the company comes from renewable sources – meaning it now produces more clean, green energy than ever before. With an average energy bill of around £41 million a year, Welsh Water plans to increase the amount of renewable energy it generates to 30% by 2020 which will help the company reduce its costs and keep bills lower for customers. 

Welsh Water Infrastructure Managing Director, Sonia McCorquodale, said: “Welsh Water is one of Wales’ largest energy users as the company uses a lot of energy to pump and treat water and wastewater. This latest investment will help the Glas Group to generate more renewable energy as we play our part in helping to manage the effects of climate change by becoming energy neutral by 2050.

“As a not-for-profit Group, we ensure that the gains we make go back directly into our services to benefit our customers, now and for generations to come.”

Cabinet Member for Clean Streets and Recycling, Cllr Michael Michael said: “All of our city’s food waste, which has historically been buried in landfill sites, is now treated at this plant where green energy is created from waste. As part of the sale, the terms and conditions of our contract remain unchanged and we look forward to working with Welsh Water, developing our established relationship as we both look to progress more, exciting renewable energy projects.”

As part of our strategy to cope with ever-increasing production demand, AJ Tensile Group recently upgraded our Manufacturing division’s 12kW Forsstrom HF welding machine to a 17kW FIAB 900. Part of the improvements involved mounting the FIAB to a 28m table, more than double the length of the Forsstrom’s old one.

Out with the old Forsstrom…

…and in with the new FIAB.

Our Biogas division recently installed this 2,100 cubic metre slab-mounted gasholder at Budd’s Farm in Havant for Southern Water and Barhale Trant Utilities. This was to replace an existing gasholder that had come to the end of its long and successful working life – a project that our Director of Engineering Richard Cherry was originally involved in.

Like most of our installations, this gasholder is bespoke to suit the client’s specific requirements, but the general design follows our own unique double-membrane construction technique. This is a tried and tested method to ensure high levels of off-site quality control and efficient on-site installation. Working pressure of this gasholder is 25 millibar.

We are pleased to report that our client and the end user are both very pleased with the final product and the whole project process.
