WASTE
WATER
TREATMENT

Since beginning of its activities, WTD has been designing Sewage Treatment Plants based on well known Activated Sludge, SBR and similar processes.

During the years, parallel to technological development, MBR processes and Advanced Oxidation for most severe waters have been added to WTD portfolio of products, also in consideration of progressively stringent Enviromental Regulations.

ZERO
LIQUID
DISCHARGE

Thanks to the experience accumulated in the various wastewater treatment processes, WTD can offer its customers solutions based on advanced zero liquid discharge treatments.

Zero liquid discharge solutions proposed by WTD adopt a combination of technologies related to membrane filtration, evaporation/crystallization, and others. Nowadays ZLD (Zero Liquid Discharge) is of primary importance. The approach in design according to ZLD is to treat and produce water suitable for reuse (irrigation, industrial processes, etc.).

Together with recovery maximization, decreasing waste volumes is also a target; both are being beneficial to the environment, and allow economical savings for plant Owner.
