Zuvamesa, Spain’s largest orange processing company, faced the challenge of increasing its effluent treatment capacity without expanding its facility’s size. Moreover, there was a critical need to reduce the average wastewater treatment costs. In partnership with SUEZ WATER Spain, which has collaborated with Zuvamesa for over five years on the plant’s operation and maintenance, a sustainable and cost-effective solution was developed using Aqana’s (Bluegen water Subsidiary) DACS® technology.

Anaerobic Innovation in the orange processing Industry
Overview: Zuvamesa, Spain’s largest orange processing company, faced the challenge of increasing its effluent treatment capacity without expanding its facility’s size. Moreover, there was a critical need to reduce the average wastewater treatment costs. In partnership with SUEZ WATER Spain, which has collaborated with Zuvamesa for over five years on the plant’s operation and maintenance, a sustainable and cost-effective solution was developed using Aqana’s (Bluegen water Subsidiary) DACS® technology.
Bluegen Water Solution: Integrating the anaerobic treatment technology into Zuvamesa’s existing infrastructure without the need for extensive expansions. This approach not only conserved space but significantly reduced operational and investment costs. The DACS® technology’s ability to treat highly concentrated wastewater (20,000mg/l COD) and recover biogas as an energy source marked a critical advancement towards sustainability and efficiency.
Achieved an 85% COD reduction, with the combined DACS® and activated sludge reactors reaching a biological efficiency of approximately 98% on COD.
The retrofit transformed the plant from a significant electrical consumer to a net energy producer, leveraging the biogas generated from the wastewater treatment.
The introduction of DACS® technology resulted in an 80% reduction in aerobic sludge volume and costs, requiring a smaller footprint for effluent treatment.
The DACS® reactor’s design ensures reliable operation throughout the year, maintaining high COD reduction efficiency even during low-season operations.
