-SEPTIC TANKS
They are units developed and produced for primary treatment of wasted water. We make a chemical and physical separation and transformation of the solid components located 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, suspension of the floating particles and reduction of the entering water speed, and secondly we proceed 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 naturally, thanks to the difference 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.
