Live fish transporting equipment - extracts water from containers continuously for oxygen enrichment and return

摘要

The equipment is used for transporting live aquatic creatures such as fish in containers on a vehicle. The oxygen content of the water in the containers is maintained at the desired level by a gas consisting at least partly of pure oxygen. Water is extracted from the containers as nearly as possible continuously, and enriched in a gasification zone after which it is returned to the containers again. Enrichment can be so carried out that the water is returned to the containers bubble-free, water circulation being effected by a motor-driven pump whose supply is assured by a standby generating set.
