WATER RECOVERY: A SECOND CHANCE FOR ALREADY USED WATER
DEISA contributes a significant experience in the optimization of water consumption,
including: recycling, selective use of water, and tertiary treatments to achieve the
regeneration of already used water and its recirculation for further reuse.
DEISA designs and build installations for these purposes. We have pilot plants used to
confirm the efficiency of the proposed treatment line, or to search for the most adequate
design.
