????Such system is said to come from Norway, it has multi advantages such as small land use, low energy cost, water saving, no pollution and high yield. The system can be used to build up 5-8 layers large production departments, and its production capacity per unit water area is 5-10 times more than the current domestic level, while its water consumption is just 1-2 percentage of traditional way.

????The introduced system has adopted nano photo-catalysis water purifying technology; water usage rate can be enhanced to 85%-95%, and the adoption of wasted water can help to increase overall water usage rate to 98%. The system has a series of advanced high sensors to control all water quality parameters automatically. The system also has an auto-feeding device, and water channel auto cleansing robot, fish auto sorting device to achieve high degree industrial automation.
