For the galvanic industry, Tecn.A. can count on its thirty-year experience for the construction of wastewater treatment plants, using chemical-physical processes, with selective ion exchange for the collection of heavy metals, using ultrafiltration and reverse osmosis for the treatment and recycling of certain streams.
The production of printed circuit boards gives rise to effluents characterised essentially by the presence of heavy metals, often in complex form, and organic substances and surfactants.
For the printed circuit board industry, Tecn.A. builds chemical-physical plants, selective resins plants and reverse osmosis plants for the recycling of waste.
A special application is the ultrafiltration of dry-film and solder development and stripping exhaust.
Tecn.A. operates in the dairy industry, producing a wide range of membrane filtration and concentration systems at its factory.
These systems make it possible to solve all problems related to the treatment of milk, whey and brine, enhancing the value of the products.
All systems are built in compliance with health and hygiene regulations.
