GRP Septic Tanks

Polyester septic tanks

Polyester septic tanks

Septic tanks carry out an anaerobic biological treatment. In the first compartment, the heaviest suspended matter is decanted and digested. In the second, the lighter suspended matters find better conditions to settle and be equally decomposed.


It is a simple system, suitable for small communities, with fairly low waste quality required. It can also be used as the first treatment of a more complex process.
