| HAR's activity is based on the design and the supply of innovative systems for waste water treatment, recovery of normally pollutant substances and water recycling
with zero discharge. In the view to offer advantageous technical-economical solutions, HAR, besides collaborating with international research institutes and world leading companies of the
field, is part of a pool of companies with complementary technological profile, and for this reason is able to supply solutions and systems based on the combination of different technologies:
Membrane separation
(microfiltration, ultrafiltration, nanofiltration, reverse osmosis, electrodialysis)
Evaporation and Crystallization
(heat pumps, thermal compression, single and multiple effect)
Bipolar membranes
(salt solutions recovery through acid/base conversion)
Membrane bioreactors
(for high COD/BOD)
Disillation
(fractionation and solvent recovery)
Ion exchange resins
Physical treatments
(wet oxidation, electrolysis for metal recovery, stripping, adsorption)
Chemical treatments
(redox, flocculation, sedimentation)
