ECOROCK-1500 Small Sewage Treatment Unit for 60 persons
The ECOROCK-1500 is a compact sewage treatment unit for up to 6 persons (P.E.) (*).

Two-stages Sewage Treatment Plant
The ECOROCK-1500 is a small-sized sewage treatment plant that caters for a 2-6 persons domestic application. The ECOROCK-1500 system functions as a two-stages sewage treatment plant. The raw sewage first enters a Primary tank to provide pre-separation and initial breakdown of organic solids. The sewage then passes through an effluent filter before discharging into the BIOROCK® unit itself which incorporates the aerobic filtration process.

Where required the BIOROCK® can be retrofitted to a traditional septic tank.

(*) Depending on effluent quality requirements it is in some cases possible to cater for more than the official amount of persons (P.E.) per unit.

Biological treatment
This later stage of the process is defined by layers of BIOROCK® media. The BIOROCK media is pretreated with enzymes in order to achieve rapid start up and to stimulate the growth of the correct bacteria type; these bacteria colonize the media in vast numbers and rapidly digest the organic waste. The treatment philosophy has been developed around a combination of aerobic/anoxic biological degradation and filtration. The BIOROCK technology advantage is further characterized by - minimal maintenance requirements & ability to handle intermittent (seasonal) loadings. (E.g. Holiday homes, Safari Lodges, Camping Sites, etc.)

Sewage treatment units for up to 60 persons are available.
