Veolia delivers industrial wastewater treatment solution for Associated British Foods in Thailand

Veolia Water Technologies has formed a partnership with Associated British Foods in Thailand to deliver in-house wastewater technologies for the food manufacturer at its Ovaltine manufacturing plant in Samutprakarn, Bangkok.

Local unit of the French utility, Veolia Water Solutions & Technologies (Thailand), operates a full turnkey wastewater treatment plant for the food company.

The facility incorporates multiple advanced technologies including Dissolved Air Flotation (DAF), Biothane Upflow Anaerobic Sludge Blanket (UASB), AnoxKaldnes Biological Activated Sludge (BAS), and Hydrotech Drumfilter, Veolia said.

The DAF unit at the plant pre-treats the raw wastewater and ensures removal of fat, oil, and grease (FOG) prior to the Biothane UASB anaerobic treatment process.

The UASB system ensures conversion of the existing COD in the conditioned wastewater into biogas.

AnoxKaldnes BAS, which is an integration of a Moving Bed Biofilm Reactor (MBBR) technology with conventional activated sludge (AS), is the next technology to be used in the process. It is used to improve the efficiency of the activated sludge process and offers better sludge settling characteristics.

The effluent is then passed through a a second DAF clarifier unit for biological sludge separation, following which Hydrotech Drumfilter system is used to separate the remaining particles from the wastewater.

Veolia Water Technologies Thailand Projects business development director Michael Poonpipat said: "We had to be creative in designing a compact yet robust wastewater treatment plant that could handle a high flow rate within a limited space.

"Working with ABF shows how we can effectively provide a full range of wastewater solutions from start to end. Our experience in the food and beverage industry has equipped us with the know-how to mitigate the client’s concerns, and we are confident of meeting their project expectations."
