Drip filtration works by pumping water from the fish tank to the top of the drip tank. When the top is full, the water drains away and slowly drops naturally into the first drip tank. Evenly distributed through the drip plate; water or drip or flow through the filter material; and then into the second drip tank. A process in which the clean water reaches the third layer at the bottom of the drip filter box and flows directly into the fish pond through the outlet

Protein skimmer also play an important role in indoor aquaculture systems by helping to separate and extract proteins from feeds, thus effectively utilising and recycling the organic wastes generated during the farming process. Extraction of proteins from feeds: In indoor aquaculture systems, artificial feeds are usually used as the main food source for cultured organisms. Protein separators can help to separate the proteins from the feed efficiently, increase protein utilisation and reduce wastage of feed. Degradation of organic wastes: A large amount of organic wastes, such as feed residues, faeces, etc., are generated during the farming process. These organic wastes, if not effectively treated, will lead to water pollution and deterioration of the farming environment. Protein separator can reduce the accumulation of organic waste by separating and recycling the protein in the waste, reduce the ammonia nitrogen and nitrogen and phosphorus content of the water body, and improve the water quality.

High-efficiency dissolved oxygenator plays a very important role in indoor aquaculture system, which can help to maintain the oxygen level in the water body, improve the water quality, and enhance the growth rate and health of aquaculture organisms. The following are the applications of high efficiency dissolved oxygen devices in indoor aquaculture systems: Improve dissolved oxygen level: In indoor aquaculture systems, the water body is prone to insufficient oxygen, especially in the case of intensive aquaculture. High-efficiency oxygen dissolver can effectively dissolve the oxygen in the air into the water, increase the dissolved oxygen level in the water body, and ensure that aquaculture organisms have enough oxygen supply.

High-pressure aerator is widely used in indoor aquaculture. It is mainly used for oxygenation and water mixing to provide a suitable ecological environment for healthy growth of aquaculture. Firstly, the high pressure aerator injects air into the aquaculture water body through jetting to increase the dissolved oxygen content in the water. Aquatic animals such as fish and shrimp need oxygen for respiration, and sufficient dissolved oxygen can provide what they need for normal metabolism and life activities. Through the use of high pressure aerator, it can effectively increase the concentration of oxygen in the water, improve the quality of the water body, reduce the accumulation of nitrogen, sulphur and other harmful substances, and improve the efficiency of aquaculture. Secondly, high pressure aerator can also be used for mixing and circulating the water body. In indoor aquaculture systems, the fluidity of the water body is very important for maintaining balanced water quality and temperature.
