The BIOROCK Primary tanks are always equipped with an effluent filter in the form of stiff plastic brush. This filter holds back suspended solids, fats and other floating matter which enables a higher quality of pre-treatment.
The filter is easy removable for maintenance. This effluent filter can be easely fitted to an existing septic tank used as primary tank in front of a BIOROCK unit. (RETROFIT applications - septic tanks upgrades)
