Biogas and Biofuels
Specialization in Digestate Treatment
At ZEWATECH, we stand out for our advanced solutions in the treatment and recycling of digestates, a key by-product in the production of biogas and biofuels. Using our evaporation technology, such as the innovative Mechanical Vapor Compression (MVC) evaporators, we focus on transforming digestates into reusable components, thus contributing to a more sustainable and efficient production cycle.
Advanced Treatment of Digestate Wastewater
Our systems are specially designed for the treatment of wastewater from digestates. This water, characterized by its high concentration of organic matter and nutrients such as nitrogen, potassium and phosphorus, requires a specialized approach. ZEWATECH’s solutions combine MVC evaporation technologies, acid mixing, stripping and condensate polishing to offer comprehensive and efficient treatment.
Key Benefits of Our Solutions
Significant Reduction in Volume and Costs
We optimize digestate processing to reduce its volume, thereby lowering transportation, storage, and dispersion costs.
Ecological and Regulatory Solutions
Our technologies not only comply with environmental regulations but also promote the separation and reuse of nutrients, supporting the creation of high-value agricultural fertilizers.
Energy Efficiency and Sustainability
Through MVC technology, we offer solutions that maximize energy efficiency and promote sustainable practices in digestate wastewater treatment.
SUCCESS CASE
DESEURAS BIOGAS PLANT
Sant Bartomeu del Grau, Barcelona
The Deseuras biogas plant stands out for the implementation of our MVC TurboFlash, achieving effective reduction and concentration of digestates. This success case reflects not only the exceptional performance of our evaporator, but also significant energy savings and superior efficiency. Thanks to the volumetric compression of our mechanical vapor compression system, latent heat is increased, distinguishing itself by its low energy cost and high efficiency. This achievement underscores our commitment to innovation and sustainability.
Other Applications in Biogas and Biofuels
In addition, at ZEWATECH we address other important applications in the biogas and biofuels sector, such as the treatment of landfill leachates and the evaporation of vinasse in the production of bioethanol, although our main focus is the treatment of digestates.
