Solids removal from the system is an important component of water quality management.
A cone bottom clarifier allows for settling and removal of solid fish feces.
Frequent removal of solids improves water quality by reducing biolochemical oxygen demand (BOD) and secondary ammonia production.
A microscreen drum filter removes solid waste from the recirculating nursery.
