Descrição

Waste waters are coming from the serigraphic process. This industrial activity generates small to medium amounts of contaminated waters that need to be treated or pre-treated. Activities like the cleaning of printing screens are responsible for generating contaminated waters loaded with ink, colloidal and dissolved matter, and a significant amount of nitrogen compounds resulting
from the use of nitric acid on the process.
