China Aquaculture filtration machine manufacturer-Xinxiang Yinuo Machineries Co., Ltd.

Aquaculture filtration machine

The Aquaculture filtration machine can accurately trap solid suspended substances such as fish feces and residual feed, with a removal rate of over 90%, controlling the content of suspended solids in water below 15mg/L. It is equipped with an intelligent automatic backwashing function, which starts automatically according to the filter clogging level, eliminating the need for shutdown for cleaning.

Working Principle of Aquaculture Filter

* The interior of the rotating drum is pumped to a negative pressure state by a vacuum pump, creating a pressure difference between the inside and outside.

* The aquaculture water flows in from the outside of the rotating drum. Driven by the pressure difference, the liquid passes through the filter screen and enters the inside of the rotating drum, while solid particles are trapped.

* The rotating drum rotates slowly, bringing the solids trapped on the filter screen to the upper part.

* The backwashing system flushes the solids into the sewage discharge tank for discharge, and the purified water flows back to the aquaculture system.

Core Advantages of Aquaculture filtration machine

Efficient and Continuous Operation

It works 24 hours a day without interruption, no need for shutdown for cleaning, and maintains stable capacity. Its filtration efficiency is more than 3 times that of traditional sand filter tanks, with a processing capacity of 30-500 m³/h.

Energy Conservation and Consumption Reduction

Compared with traditional filtration systems, its energy consumption is reduced by 40%. The equipment is compact, reducing the occupied area by 70%.

Extended Equipment Service Life

As a pre-treatment device, it reduces the load of subsequent biochemical filter tanks by 40% and doubles the service life of membrane modules.

Improved Aquaculture Benefits

It maintains clear and stable water quality, reduces fish stress, lowers the incidence of diseases, and accelerates fish growth rate. The water recycling rate can reach 90-99%, which significantly reduces the frequency of water change and saves water resources.

Consequences of Low Filtration Efficiency in Aquaculture filtration machine

Water Quality Deterioration: Suspended solids accumulate, reducing water transparency and dissolved oxygen levels. Concentrations of toxic substances such as ammonia nitrogen and nitrite rise, directly endangering fish health.

Disease Outbreaks: Poor water quality weakens fish immunity, making them susceptible to various diseases. Decomposition of solid organic matter creates a hotbed for pathogen growth, increasing the risk of cross-infection.

Soaring Aquaculture Costs: Frequent water changes raise costs for water resources and energy consumption. Frequent fish diseases lead to higher medication costs, lower survival rates, and reduced yields. Frequent backwashing of equipment accelerates wear and tear, increasing maintenance and replacement costs.

Risk of System Collapse: Solids clog subsequent biological filters, disrupting microbial communities. The service life of filter media is significantly shortened, reducing system stability and even triggering "pond turnover" accidents.

Ecological and Environmental Pollution: Direct discharge of aquaculture tailwater without effective treatment causes eutrophication of surrounding water bodies. This violates environmental protection regulations, leading to the risk of penalties and affecting sustainable development.
