Case Study Suntory – Advancing Water Sustainability

Before the system development, Suntory faced a range of challenges impacting water sustainability and plant operations: 

• Wastewater Management: large capacity water treatment systems producing large volumes of waste
• Design Delays: Tank redesign complexities and the integration of multiple water treatment plants to achieve hygienic standards created project holdups
• Hygiene Standards: Requirement for fully hygienic process and tight microbiological specifications, including the need for HEPA-filtered flush tank air entry for compliance.
• System Integration: Coordination across multiple engineering consultants and existing plant infrastructure
• Reliability Requirements: Need for a low-maintenance, compliant and user-friendly serviceable systems. 

BHF developed and delivered a tailored solution for Suntory’s evolving needs: 

• Custom UF + RO System: Advanced ultrafiltration and reverse osmosis combination
• Hygienic Design: Sanitary design including HEPA-filtered air entry for the flush tank to maintain system cleanliness
• Space-Efficient Modular Build: Designed to fit site layout constraints
• Fully Integrated CIP & PLC Controls: Streamlined operation, cleaning and remote system management
• Delivered with SAT and Operator Training: Ensured smooth startup and operational confidence
• Built for Long-Term Maintainability: Aligned with Suntory’s ongoing operational goals 

Implementation 

Despite design complexities, BHF delivered the system with efficient delivery and effective communication. The project included full commissioning, Site Acceptance Testing (SAT) and comprehensive operator training to ensure a seamless handover. 

Water and Environmental Benefits: 

• Design focus to ensure significant reduction in wastewater discharge volume
• UF System and Recovery UF combine to produce 220 kl/hr during operation @ 99.98% Water Recovery. Conventional design UF is 90 – 95% % recovery UF. At full production that has the potential to save up to 21,950 l/hr compared with conventional design. 
• RO System & Recovery RO combined to produce 150 kl/hr during operation @ 94.4% Water Recovery. Conventional Design RO is 80-90% RO Recovery. At full production that has the potential to save up to 21,600 l/hr compared with conventional design.
• Combined potential water savings of 43,550 l/hr
• As a new Greenfield site, this is a standout waste recovery design with approximately 50% energy savings in a low energy focused design.
• Both supplier and customer are proud of this world leading Sustainable design 

Operational Improvements:

• Safer, cleaner operation with HEPA air supply to treated water tanks 
• Optimised Antiscalant 
• Sanitary design, fully heat sanitisable 
• Unique energy savings design to ensure min energy use during production downtime whilst maintaining system hygiene and integrity
• System reliability and maintainability confirmed through a thorough SAT and purpose designed maintenance program
