CULTURED ALGAE WATER CONCENTRATION SYSTEM AND METHOD FOR OPERATING CULTURED ALGAE WATER CONCENTRATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an algae water concentration system for concentrating algae water in a culture pond into algae water containing desired sized algae with a simplified configuration at low cost with high efficiency; and a method for operating the system.SOLUTION: There is provided a cultured algae water concentration system 100 comprising an algae water supply unit 17 and an algae water concentration unit 16. The algae water supply unit 17 includes an algae water supply vessel 18 storing algae water from a culture pond and a supply vessel outlet port 19 for taking algae water from the algae water supply vessel. The algae water concentration unit 16 includes a concentration vessel 1 for receiving and concentrating algae water from the algae water supply unit; a filter 3 that partitions the concentration vessel into upper and lower spaces and prevents algae having equal to or greater than a predetermined size from being passed therethrough; a vibration device 5 that causes the filter to vibrate in the out-of-plane direction; a concentration vessel algae water inlet port 7 disposed below the filter of the concentration vessel to introduce algae water into the concentration vessel; a concentrated algae water outlet port 9 disposed under the filter of the concentration vessel to retrieve concentrated algae water from the concentration vessel; and a filtered water outlet port 8 disposed above the filter of the concentration vessel to discharge water filtered through the filter.SELECTED DRAWING: Figure 1
