Orenco® Biotube® FT-Series Commercial Effluent Filters remove
about two-thirds of suspended solids from effluent, helping extend
drainfield life. They are used in new or existing tanks, for commercial
or heavy residential use. Biotube FT-Series Commercial Effluent
Filters come with a filter cartridge, PVC housing, and an extendable
PVC handle. A slide rail is available as an option for large filters, to
make it easier to install and service them, and it is required on filters
for tanks that have only one access location.
