RADIAL COMPRESSOR

the use aerator in the fish farming system

Abstract

This article aims to demonstrate the importance of aerators available in the industry, acting directly on the quality and oxygenation of water in fish farming systems in artificial tanks. The water has average oxygenation of 5mg/l and, initially, it is enough for the fingerlings to survive. However, over time, due to the growth of fish, leftovers of fish feed, and waste that end up accumulated in the tanks, bacteria start to form and consume oxygenation. For this reason, the oxygen level becomes insufficient, requiring the use of aerators, which generate air diffusion, considerably increasing the level of dissolved oxygen in the water (DO), which for good fish culture should be between 4mg/l 11mg/l. There are several types of aerators, and one of them is the radial compressor or air blower type aerator, which currently has the best cost-benefit ratio for fish farming in artificial tanks. Considering the effectiveness of compression aerators, in the tilapia breeding system, this research aimed to obtain information, data, and analysis of the results of implementing an aerator of this type. This system is completely independent and electrical, making it possible to regulate the amount of oxygenation introduced into the water. In addition, it has an external filter that sucks air directly from the environment and is made of aluminum, an important feature when it comes to an environment with a high rate of corrosion, optimizing its functionality.
