The EN Onion Septic range allows the solids to settle in the form of sludge with the lighter liquid undergoing a biological process through the contact with the oxygen. This allows the solids to further break down, the lighter liquid still contains smaller particles of solids and high levels of BOD but passes through the septic tank into the drainage field.
