WPL’s energy efficient biological wastewater treatment technology will feature in a presentation delivered to Welsh Water’s innovation team on 11 September 2018. The Innovation Exchange, organised by British Water, is taking place at Cardiff City Stadium, home of the city’s football club and Wales’ national team.

WPL’s presentation – Reshaping Biological Performance – will be delivered by Andrew Haywood, WPL utility sales manager. The event offers a unique opportunity to present innovative solutions that meet the challenges faced by Welsh Water directly to the utility’s senior decision-makers.

The water company is a semi-mutual run on a not-for-profit basis and says it is looking for technological advances could lead to significant efficiencies in the planning, delivery and operation of new assets in AMP7 (2020-25). Some 94% of Welsh Water’s wastewater treatment sites are under 10,000 population equivalent (PE), making them ideal for the new wave of easy-to-operate, energy efficient packaged treatment.

The Dŵr Cymru Welsh Water team will find out how research and development at WPL has enhanced process efficiency significantly. The company’s submerged biological treatment technology now uses less power and can be adapted to fit any existing wastewater treatment vessel including steel, concrete and glass-reinforced plastic (GRP).

Technical director Andrew Baird, who is also convenor of British Water’s Wastewater Treatment Plant Focus Group, will also be attending the event. He said, “WPL submerged biological treatment technology fits more process capacity inside each vessel.

“This not only brings down energy use per m³ treated, it also brings down the site footprint required. With changes and a tightening of discharge standards, in most instances, upgrading an existing works requires no additional tank capacity.

“The flexibility of the modular treatment cells designed by our specialist team can’t be matched, they can be specified to fit within any vessel. The units are then manufactured off-site at our purpose-built facility, making transportation and installation quick and very straightforward. This approach minimises both the onsite labour requirement and health and safety risk.”

 

WPL | Reshaping Biological Performance

  • WPL’s submerged biological treatment technology (patent pending) fits more process capacity inside each wastewater treatment works (WwTW) vessel – new and existing
  • This not only brings down energy use per m³ treated, it also brings down the site footprint required
  • Developments in hydraulic control and retention times have also enabled WPL’s process technology to consistently achieve final effluent Ammonia concentrations of less than 1 mg/l on a 95%ile basis.
