Veolia supplies in-house wastewater technologies

Turnkey project maximizes treatment flow within limited land space.
 
Veolia Water Solutions & Technologies (Thailand) Ltd has built a partnership with Associated British Foods (Thailand) Ltd, where Veolia provides the multinational food manufacturer with a full turnkey wastewater treatment plant. This project integrates several of Veolia’s innovative technologies – including its Dissolved Air Flotation (DAF), Biothane® Upflow Anaerobic Sludge Blanket (UASB), AnoxKaldnes™ Biological Activated Sludge™ (BAS), and Hydrotech™ Drumfilter – within ABF’s Ovaltine manufacturing plant in Samutprakarn, Bangkok. With this end to end wastewater package, ABF will be able to handle its wastewater treatment needs onsite, catering to both existing and future flow requirements projected for the next decade.
 
Michael Poonpipat, Project Business Development Director, VWT Thailand, said, “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 knowhow to mitigate the client’s concerns, and we are confident of meeting their project expectations.”
 
The challenge
Faced with the challenge of designing a wastewater treatment plant located within the client’s space constrained manufacturing grounds, Veolia recommended key technologies that could effectively treat their wastewater volumes and COD loads.
Poonpipat shared, “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. One of the most attractive features of Veolia’s water and wastewater solutions is its compact design, which takes into account space constraints that clients face without compromising on performance.
 
The technologies
Apart from its efficient design, Veolia’s Dissolved Air Flotation (DAF) unit pretreats the raw wastewater, removing fat, oil, and grease (FOG) before the Biothane® UASB anaerobic treatment process. The UASB anaerobic system then converts COD present in the conditioned wastewater into biogas. Veolia’s AnoxKaldnes™ BAS™, a combination of Moving Bed Biofilm Reactor (MBBR) technology with conventional activated sludge (AS), is next applied to promote a stable and more efficient activated sludge process with improved sludge settling characteristics. The effluent then enters a second DAF clarifier unit for biological sludge separation, before the Hydrotech™ Drumfilter system separates the remaining particles from the wastewater.
 
Turn wastewater to energy
As companies become more aware of their environmental footprint, manufacturers are now actively seeking to employ sustainable business practices. Through Veolia’s recommended suite of wastewater solutions, the client can obtain biogas in the process of treating its wastewater, which becomes an alternative energy source for heating boiler systems that are used in manufacturing ABF’s products.
 
Michel Otten, Technical Director, Asia Industrial, Veolia Water Technologies, concluded, “This project with ABF carries great significance for Veolia as it showcases our ability across disciplines, from conducting preliminary market studies, to recommending targeted engineered solutions, and finally to constructing the wastewater treatment plant. It reaffirms Veolia’s leading position as a professional water and wastewater solutions supplier, and also as a trusted design-and-build partner for manufacturers across different markets. Veolia looks forward to working closely with ABF to ensure flawless project execution for a successful handover in June 2016.”

The MBBR Pack provides all the advantages of a conventional MBBR system, in a standard prefabricated package with a Plug & Play function that is easy to install.
 
Veolia’s MBBR Pack is an effective and reliable solution, even contending with wide swings in the volumes of wastewater to be treated and the carbon and nitrogenbased pollutants to be eliminated. Its small footprint, quick delivery and plug-and-play installation and commissioning translate to a reduction in civil engineering and infrastructure costs while ensuring continuity of sanitation services during works. Its modular design makes for easy transportation and expansion. Bundling with various Veolia pre or post treatment processes allows for the MBBR PACK to perfectly address the needs and quality objectives of each client.
