Veolia wins flagship Liquor Treatment Plant contract with Welsh Water

Veolia Water Technologies has been awarded a contract to supply a flagship Liquor Treatment Plant (LTP) at Dŵr Cymru Welsh Water’s Five Fords Wastewater Treatment Works (WwTW), near Wrexham, North Wales.

Welsh Water, together with their partner Mott MacDonald Bentley (MMB), are developing a flagship sludge treatment centre at Five Fords WwTW.

Welsh Water, the only not-for-profit water company in England and Wales is investing £35 million to transform Five Fords into an innovative energy park – the first of its kind in the industry to incorporate solar, advanced anaerobic digestion and hydro generation schemes at one site.

Liquor Treatment Plant LTP at Five FordsAs a result of the substantial increase in the sludge throughput and implementation of a thermal hydrolysis process plant, a new LTP is required to treat the centrate prior to return to the inlet of the WwTW.

Veolia’s solution for Five Fords WwTW is a HYBASTM (IFAS) ANITATM Mox plant. The process enables both aerobic nitritation and anoxic ammonia oxidation to take place on a one-stage biofilm process.

HYBASTM (IFAS) technology using suspended carriers has been a proven application of the moving bed biofilm reactor (MBBR) process for more than 20 years. Applying the same concept to ANITA™ Mox has shown significant benefits.

Veolia and its dedicated MBBR division AnoxKaldnes is the world leader in MBBR technology - since the 1980’s Veolia’s MBBR processes have been applied globally to a wide variety of applications.

Veolia now has ANITATM MOX municipal and industrial reference plants in the UK and globally, with the first plant now in successful operation since 2010.

In 2016, the Veolia group supplied 100 million people with drinking water and 61 million people with wastewater service, produced 54 million megawatt hours of energy and converted 30 million metric tons of waste into new materials and energy.
