Traditional versus BIOROCK

BIOROCK® provides a revolutionary and efficient system when compared with many of the other wastewater treatment plants available today. The superb results produced by BIOROCK plants have placed our systems in a leading position when compared with older & traditional techniques - such as Activated Sludge, SBR, and so on. So many systems on the market are characterized by their energy consumption, high maintenance costs, significant operational costs and a high volume sludge production which leads to frequent de-sludging.
