The 3,600 m3/day wastewater treatment plant allows a total daily production of 8,980 Nm3 of biogas which is used in the factory boilers, resulting in considerable savings on natural gas.
WD News: Veolia’s patented solutions for wastewater treatment and biogas production are now in service at Pınar Süt’s factory in İzmir, Turkey, allowing the company to meet new discharge legislation and achieve its environmental commitments, reducing carbon emissions by 17% and generating substantial savings on natural gas.
Pınar Süt, one of the biggest dairy companies in Turkey producing mainly milk, yoghurt, cheese, fruit juices, ketchup and mayonnaise, has acted on its plans for sustainable development with the recent wastewater treatment plant. The treated water is suitable for reuse with further tertiary treatment for certain applications in the factory such as flushing water, which contributes to sustainability objectives of Pınar Süt.
Two Veolia-patented technologies allow the production of valuable biogas. The wastewater first goes through a screen and Idraflot® dissolved air flotation unit to retain fat, oil and grease (FOG) and suspended solids before entering the Biobed® EGSB granular biomass anaerobic treatment unit where over 80% of the chemical oxygen demand (COD) is removed. This treatment stage produces about 45% of the biogas generated at the plant. The FOG retained in the DAF is combined with other organic waste and sent to a Biobulk™ CSTR unit for purification and further biogas production.
“The earnings from such holistic plants give us trust for the future and further steps in the name of our prior sustainability policy.” stated Ozlem Yalçın, Plant Director of Pınar Süt Izmir.
“The advanced technologies allow reuse of treated wastewater and production of renewable, clean energy, reducing the strain on local fresh water resources and environmental footprint of installation.” remarked Thierry Froment, CEO Middle East for Veolia Water Technologies.
