Can Aquaculture Production Lines Reduce Wastewater And Waste?

Fish and shrimp feed production lines require even greater environmental upgrades than poultry and livestock feed lines. For example, the cleaning of extruders and pellet mills during production generates wastewater containing fishmeal and starch, which would pollute water bodies if discharged directly. Furthermore, the dust generated during fishmeal crushing is harmful to worker health. Future environmental upgrades will focus on "zero wastewater discharge, full utilization of waste materials, and no dust dispersion."

3 landing directions

1. Wastewater Recycling: Water from Equipment Cleaning Will Not Be Discharged Directly

Future aquatic feed production lines will be equipped with a "wastewater treatment system"-wastewater from cleaning equipment will first enter a sedimentation tank (to settle fishmeal residue and starch residue), then be filtered and disinfected (e.g., using ultraviolet light sterilization). The treated water can be reused to clean equipment, mix raw materials, and even irrigate the plant's green areas, achieving "zero wastewater discharge." The settled fishmeal residue can also be recycled back into feed, preventing waste (1 ton of wastewater can recover 20kg of fishmeal residue, equivalent to saving 100 yuan in costs).

2.Full Waste Utilization: No More Waste and Dust to be Thrown Away

Currently, the production of fish and shrimp feed generates a lot of waste (such as fine powder sieved out after pellet cooling), which is mostly thrown away directly. In the future, this waste will be "fully recycled"-the waste can be re-crushed and mixed into the raw materials to make feed again (for example, 1 ton of finished product will produce 50kg of waste, which can be recycled to make an additional 45kg of feed); the dust generated from crushing fishmeal will be sucked away by a "dust collector," compressed into small pieces, and mixed into the formula (for example, making micro-particle feed for small fish fry, which requires fine powder), so that it won't be scattered everywhere and can be turned into a valuable resource.

3. Energy-saving equipment consumes less electricity: Lower carbon footprint in production processes

Future aquatic feed production lines will feature more energy-efficient equipment. For example, the heating elements in intelligent extruders will use variable frequency heating (automatically reducing power when the temperature is sufficient, unlike the current continuous full-power operation), saving 20% of electricity; the cooling machine's fans will use variable frequency fans (adjusting speed according to particle temperature, avoiding continuous high-speed operation), saving another 15% of electricity; and the production line's lighting and air conditioning will be powered by solar energy, reducing carbon emissions.

Benefits of environmental protection

For example, wastewater recycling can save thousands of tons of water costs per year; waste recycling can save several tons of raw material costs per year; and energy-saving equipment can save tens of thousands of yuan in electricity costs per year. For aquatic feed mills, environmental protection is not about "spending money to comply with regulations," but a win-win situation of "saving money and protecting the environment."
