SUEZ Water Spain Installs A DACS® Anaerobic Digestion Plant In The ZUVAMESA Factory In Valencia

SUEZ Water Spain has designed and commissioned an anaerobic digestion plant using DACS® technology; this new plant will treat the effluent from the orange and clementine juice and its by-products factory that ZUMOS VALENCIANOS DEL MEDITERRANEO, S.A. (ZUVAMESA) has in Sagunto, Valencia.

The company distributes DACS® exclusively in Spain and Portugal. DACS® is an innovative anaerobic treatment process patented by the company AQANA. Anaerobic treatment is the process by means of which microorganisms break down biodegradable material in the absence of oxygen. This process generates various gases, especially methane, which can be used as fuel. With this treatment the effluent toxic pollutants are t removed, obtaining a final water quality suitable to be discharged into the public waterway.
Treating waste water with DACS® technology allows the biogas produced to be recovered as an energy source. Energy costs are also reduced compared with aerobic purification (as there is no need to aerate the reactor), the volume of sludge generated is reduced and the necessary footprint to treat the effluent is smaller.

DACS® also allows to treat effluents with a high organic load, such as in juice manufacturing processes, optimizing the economic balance of the factory with the most robust system on the market.

With this new plant, ZUVAMESA has managed to increase the effluent treatment capacity without having to expand the size of its treatment facilities. It has also reduced waste production,  enable to generate important savings in electricity and natural gas consumption, and reuse 100 % of the biogas generated in its thermal power generation processes for water treatment and for the manufacturing.

SUEZ Water Spain and ZUVAMESA have been working together for over two years on the operation and maintenance of its effluent treatment plant in the Sagunto factory. Choosing to install DACS® technology emphasises ZUVAMESA commitment to their circular economy strategy, closing the loop of the life cycle of products through greater recycling and reuse, and providing benefits both for the environment and for the economy.
SUEZ Water Spain, a subsidiary of SUEZ, is a global benchmark in water management products and services, for both municipal and industrial and agricultural customers, with the aim of improving the quality of life of people.
