WTE Ltd.Settlement Tanks for the BIOROCK
The BIOROCK sustainable wastewater treatment system requires a settlement tank prior to the BIOROCK plant.
The first tank is a single stage or two stage settlement tank which, if required, is correctly sized for the BIOROCK model supplied. Most 2 chamber existing septic tanks can be used as settlement tanks or WTE can supply a new one as part of the system on request. They are made especially for WTE by Condor. They are supplied with an effluent filter to prevent suspended solids from exiting the settlement tank.
You can use a two chamber brick or concrete septic tank as the settlement tank if it is the correct size and in good condition. In this case you only need to order the BIOROCK sewage treatment plant itself, not the Biorock system. You cannot use an 'onion' shaped septic tank as the effluent is too septic.
