A leading DACH dairy processor faced rising wastewater surcharges and tightening discharge limits at one of its largest facilities. CIP cycles, pasteurization cooling and process water generated effluent loaded with high COD, phosphates and fats — straining municipal infrastructure and inflating operating costs.
RIEFILT structured a Build-Own-Operate-Transfer (BOOT) contract for an integrated wastewater treatment and recycling plant with zero-liquid-discharge capability. The system combines DAF pretreatment, anaerobic digestion, MBR biological treatment and RO polishing.
The facility reached full regulatory compliance within 60 days of commissioning. Freshwater draw dropped by 70%, saving an estimated €720,000 annually in water and effluent fees. The BOOT structure removed €3.2 M of CapEx from the client's books while delivering guaranteed performance under a 12-year contract.
Food and beverage producers operate on thin margins and tight CapEx budgets. The BOOT model converts a multi-million euro infrastructure investment into a predictable monthly operating expense — and shifts all technology, performance and compliance risk to RIEFILT. The client focuses on production; RIEFILT handles the water.
RIEFILT provides 24/7 remote monitoring, scheduled maintenance, consumables management and full regulatory reporting throughout the contract period.
