Water becomes a resource again

SCARICO ZERO 5

As the word says, zero discharge sewage treatment plants are characterized by the total absence of water emissions.

 

In all industrial contexts where purified water cannot be discharged into surface water or sewerage, Blue Water Technologyprovides zero-discharge sewage treatment plants that reuse waste water as part of the production process, turning them back into a resource.

 

Over the years, we have developed advanced technologies to minimise industrial waste and where possible treat it for recycling. This approach guarantees objective advantages: recovering the water used by reusing it in the production cycles reduces the volume of pollutants to be sent to external disposal and, in some cases, makes it possible to reuse the products used for processing.

 

Zero-discharge water treatment plants thus generate a double saving, which often proves to be a real investment and an economic gain for the company.

 

Recycling is better than discharging: by installing ad hoc plants (evaporation, nano-filtration, osmosis, ultra-filtration and others), wastewater becomes a valuable resource for the production cycle, without industrial discharges and without fear of sanctions by the authorities.

Zero-emission transformation: how it works

The zero discharge transformation can  be implemented on existing chemical-physical plants for the purification of industrial waste water resulting from galvanic treatments, mechanical workshops, chemical industries, food, laundry, painting, car washes and other contexts.

 

In many cases and without prejudice to the necessary plant considerations (drag, insertion recoveries, washes, etc.), it is therefore possible to obtain a zero discharge through the conversion of chemical-physic efficient plants to resins, such as recirculation demineralizers. The latter are not only more economically viable, but also fully in line with legal requirements.

 

In other cases, however, it will be possible to extend the current chemical-physical purification process with membrane and vacuum concentrator recirculation plants .

 

Zero-discharge sewage treatment plants operate in  specific phases:

  • De-oiling
  • Possible dechromatization and/or decyanidation
  • Acidification, coagulation, adsorption, decomplexation
  • Neutralization
  • Flocculation
  • Sedimentation/ decantation
  • Sludge filtration
  • Final filtration of the purified water:
    • Quartzite
    • For granular activated carbon
    • Using selective resins (for heavy metals)
  • Ultra-filtration
  • Osmosis
  • Evaporation
  • Collecting and pumping
