In PLASTICOS PROANCO, S.A., we make diferent equipments for purification, for both, solid and liquid residues and for different sectors such as industrial, residencial entertaining, according to our cutomer's specification.                                             

-SEPTIC TANKS
They are units of primary treatment for water, where we make a chemical and fisical separation and transformation of the solid materials in the water. It’s a cheap and easy way of treating water. First of all we start with a decantation of the solid substances, supension of the floating particles and reduction of the entered water speed, and secondly we process with the cleaning of the water after the digestion or fermentation, due to the anaerobic bacteria.

- BIOLOGICAL FILTERS
It’s a system of biological depuration of residual waters, where oxidation is produced making the residual air and water circulate through a filter. The air circulation is made naturaly, thanks to the diference between the air and water temperature. Due to the interior air heating or cooling, a difference of density is produced provoking the air circulation. The biological filter complements this way the residual water depuration.
