1. Solid Particle Removal System Design
Total Suspended Solids (TSS) is commonly used as a parameter to measure solid particulate matter in Recirculating Aquaculture System (RAS). It mainly refers to the total amount of solid particles with a particle size greater than 1 micron in a unit of water. In the circulating water system, TSS includes fish feces, residual bait, biological flocs (dead and live bacteria), etc. The size of these suspended particles varies greatly from micrometer to centimeter level. Suspended particulate matter can directly affect the health and growth of fish (especially cold water fish), and also increase the burden on biofilters. Therefore, it is necessary to maintain the concentration of suspended particles in the circulating water within a reasonable range.
In some EU countries' Recirculating Aquaculture System (RAS) systems, the control of suspended particulate matter is relatively strict. For example, for water bodies used for Recirculating Aquaculture System (RAS), the concentration of suspended particulate matter (measured by total suspended solids TSS) is usually expected to be controlled below 15mg/L to maintain good water quality and ecological environment.
The United States also has relevant water quality regulations in the fields of aquaculture and water treatment. In the Recirculating Aquaculture System (RAS) system, the corresponding suspended particulate matter content (converted by turbidity and other related indicators) also has certain limitations. The ideal range for suspended particulate matter concentration is around 8-12 mg/L, which is used to ensure the survival and reproduction of aquatic organisms.
In the actual operation of the factory based Recirculating Aquaculture System (RAS) system in China, it is generally required to control the suspended particulate matter concentration (suspended solids SS) below 10mg/L. For some precious species that require high water quality, such as salmon, it is even required to control it below 5mg/L.
2. Dissolved Contaminant Removal Parameters
Water solubility includes soluble inorganic substances and soluble organic substances. Among them, water-soluble harmful substances are mainly ammonia nitrogen (NH3-N) and nitrite nitrogen (NO2-- N). Ammonia nitrogen can enter the bloodstream through the gills and skin of fish, disrupting their normal tricarboxylic acid cycle, altering their osmotic pressure, and reducing their ability to absorb oxygen from water, thus affecting their normal growth and survival.
The commonly used fixed membrane nitrification biofilter in Recirculating Aquaculture System (RAS) systems is the ammonia nitrogen conversion bacterial community that grows on the surface of a certain biological packing material, and ammonia nitrogen is transferred to the fixed biofilm through diffusion and converted. The main purpose of the biological filter process design is to ensure that the filter has sufficient nitrifying bacteria to remove ammonia nitrogen excreted by fish, maintain the ammonia nitrogen concentration in the aquaculture system within the predetermined range, and ensure the safety and effective growth of fish.
2.1 Ammonia Nitrogen (NH₃-N) Control
Ammonia nitrogen is one of the main pollutants dissolved in water in Recirculating Aquaculture System (RAS) systems. It mainly comes from the excrement and residual feed of farmed organisms. High concentrations of ammonia nitrogen can be toxic to farmed organisms, affecting their growth, immunity, and reproductive ability. In biofilters, the removal of ammonia nitrogen mainly relies on the nitrification of microorganisms such as nitrifying bacteria, which convert ammonia nitrogen into nitrite and nitrate.
When designing a biofilter, sufficient surface area and volume of the filter material should be considered to provide enough space for nitrifying bacteria to grow and reproduce. At the same time, it is necessary to control the ammonia nitrogen load in the influent and avoid excessive ammonia nitrogen concentration from impacting the biological filter. For example, the concentration of ammonia nitrogen in the influent can be reduced by using an automatic feeding machine and adopting a feeding strategy of small amounts and multiple meals. Determine the allowable ammonia nitrogen concentration for the biofilter based on the ammonia nitrogen tolerance and breeding density of the cultured organisms. Generally speaking, for most freshwater aquaculture fish, the total ammonia nitrogen concentration should be controlled below 1mg/L, and non-ionic ammonia should not exceed 0.025mg/L.
2.2 Nitrite (NO₂⁻-N) Control
Nitrite is also a water quality parameter that needs to be closely monitored in the Recirculating Aquaculture System (RAS) system. It is an intermediate product in the process of ammonia nitrogen nitrification and is also toxic to aquaculture organisms. Nitrite can affect the transport of oxygen in the blood of farmed organisms, leading to symptoms of hypoxia such as shortness of breath, floating heads, and even death.
In the design, it is necessary to ensure that the biofilter can effectively further convert nitrite into nitrate. This requires maintaining the activity of denitrifying bacteria in the biofilter and providing them with suitable environmental conditions, such as appropriate dissolved oxygen. Generally, it is required to control the concentration of nitrite below 0.5mg/L.
2.3 Seawater Aquaculture Considerations
The salinity of seawater is relatively high, containing various ions such as sodium ions (Na ⁺), chloride ions (Cl ⁻), magnesium ions (Mg ² ⁺), calcium ions (Ca ² ⁺), etc. Marine aquaculture organisms have evolved complex ion regulation systems during their long-term adaptation to high salt environments. When nitrite enters marine organisms, these organisms can partially alleviate the physiological effects of nitrite by utilizing their own ion regulation system. In Recirculating Aquaculture System (RAS), chloride ions (Cl -) can reduce the toxicity of nitrite (NO2-) to aquaculture organisms through competitive inhibition. Specifically, both chloride ions and nitrite need to enter the fish body through the chloride cells on the gill plates. The presence of chloride ions increases the difficulty of nitrite entering the fish body, thereby reducing its toxicity. In general, when the concentration of chloride ions in water is six times that of nitrite, it can effectively inhibit the toxicity of nitrite to aquaculture organisms. Compared to freshwater aquaculture, seawater aquaculture has less toxic hazards from nitrite, which is related to the higher concentration of chloride ions in seawater. Therefore, in the Recirculating Aquaculture System (RAS) system, by regulating salinity reasonably, the toxicity of nitrite can be effectively reduced, and the health and safety of aquaculture organisms can be protected.
3. Dissolved Oxygen (DO)
In a Recirculating Aquaculture System (RAS) system, dissolved oxygen (DO) is a key water quality parameter. Fish and other aquatic organisms absorb dissolved oxygen from water through gill respiration to maintain their metabolic activity. The dissolved oxygen concentration required for the normal growth of most warm water fish is generally around 5-8mg/L. When the dissolved oxygen concentration is below the critical level, the respiration of aquatic organisms will be inhibited, their growth rate will slow down, their immunity will decrease, and they are prone to infection with diseases. For example, when the dissolved oxygen is below 2mg/L, many fish will experience floating head phenomenon, and prolonged exposure to low dissolved oxygen can lead to fish death.
In Recirculating Aquaculture System (RAS), it is recommended to maintain dissolved oxygen between 8-10 mg/L. Higher dissolved oxygen is beneficial for increasing feeding levels and reducing feed to feed ratios.
4. pH Control
In a Recirculating Aquaculture System (RAS) system, the suitable pH range for fish is usually between 7.0-8.5. For example, most freshwater fish grow well in environments with pH 7.2-7.8. This is because within this pH range, the physiological functions of fish, such as respiration and osmotic pressure regulation, can be carried out relatively normally. Gas exchange occurs through the gills, and the appropriate acidity or alkalinity in water facilitates the normal exchange process of oxygen and carbon dioxide.
For shrimp farming, such as South American white shrimp, the suitable pH range is roughly 7.8-8.6. This is due to the physiological structure and activity characteristics of crustaceans, which make them more adaptable to slightly higher pH environments. Suitable pH is beneficial for the molting growth of shrimp.
However, during the process of Recirculating Aquaculture System (RAS), the pH value will continuously decrease as the aquaculture progresses, and it is necessary to adjust the pH value of the water. Automatic pH adjustment equipment can be used. Automatically adjust the pH value of the water body based on pH sensor data.

Canvas fish pond is a common fish keeping container made of canvas material. It is usually designed in a round, square or rectangular shape and can be chosen in different sizes and depths according to the needs. The material and shape of the canvas fish pond have an important impact on water quality and fish life. The following will introduce in detail the influence of the material and shape of the canvas fish pond on the water quality and fish life.
1. The influence of the material of canvas fish pond on water quality and fish life
Air permeability of canvas material: The material of the canvas fish pond should have good air permeability, because fish need sufficient oxygen to maintain life activities. If the material of the canvas fish pond is airtight, oxygen cannot enter the water through the material, which will reduce the dissolved oxygen content in the water body, affect the normal breathing of fish, and even cause fish to suffocate.
Weather resistance of canvas material: Canvas fish ponds are usually placed outdoors and need to withstand the test of various climatic conditions. The canvas material should have good weather resistance and be able to resist the influence of natural environments such as sunlight, rain, wind and snow. If the canvas material has poor weather resistance and is easily damaged or aged, it will cause problems such as water leakage and cracking in the fish pond, which will affect the stability of water quality and the living environment of fish.
Anti-corrosion property of canvas material: The material of canvas fish pond should have certain anti-corrosion property, in order to prevent the problem that plastic materials are easy to bring harmful substances to the pool water. If the material of the canvas fish pond is not corrosion-resistant, it may release toxic substances, which will adversely affect the health of fish.
2. The impact of the shape of the canvas fish pond on water quality and fish life
Depth of fish pond: Fish have certain requirements for water depth, so the depth design of canvas fish pond should be reasonable. If the fish pond is too shallow, it is not conducive to the growth and movement of fish, and it will also cause fluctuations in the temperature and oxygen content of the water body. And if the fish pond is too deep, it is easy to cause the oxygen above the water body to be unable to fully dissolve into the water, which will affect the breathing of bottom fish.
The shape of the fish pond: the shape of the canvas fish pond can be round, square or rectangular. Different shapes of fish pond designs will have a certain impact on water quality and fish life. The design of the circular fish pond is more reasonable, which is conducive to the circulation of water flow and the swimming of fish. When designing a square or rectangular fish pond, it is necessary to consider the fluidity of the water flow, avoid dead ends and siltation, so as not to affect the water quality and fish life.
The capacity of the fish pond: The capacity of the canvas fish pond will also have a certain impact on the water quality and fish life. Fish ponds with small capacity are easily affected by violent fluctuations in water temperature and water quality, and are not suitable for long-term fish breeding. A fish pond with a larger capacity can provide a more stable water quality environment, which is conducive to the growth and reproduction of fish.
