Fish farmer's 'lie flat' artifact: a full-automatic microfilter = year-round no water changes + electricity bill savings of 40%?

I. Appearance and structural design

1. Traditional Fish Pond Filter
   • Civil engineering is too cumbersome, construction is complex, and design requirements are low.
   • It consists of multi-compartment filtration bins (sedimentation bin, brush bin, biochemical bin, clean water bin, etc.) and requires pre-buried pipes and cables.
   • Large footprint, usually takes up 1/5 to 1/3 of the fish pond area.
   • Bulky appearance, mostly open structure, need to cooperate with civil engineering.
2. Automatic rotary drum microfiltration machine
   • Integrated design, integrated physical filtration, biochemical cultivation of bacteria, ultraviolet sterilization and disinfection, backwashing and other functions in one, compact structure.
   • Easy to install and easy to maintain.
   • Small footprint, only needs to be placed near the fish pond, no additional civil construction required.
   • Simple appearance, with stainless steel or industrial grade cabinet, suitable for modern yard design.

Second, performance and filtration effect

1. Filtration accuracy and efficiency
   • Traditional filtration pool: rely on coarse filtration media such as filter cotton, brush, etc., with low filtration precision (usually ≥500μm), unable to intercept tiny particles, and with the risk of secondary pollution.
   • Rotary drum microfilter: 316 stainless steel screen, filtration precision up to 150μm, solid-liquid separation efficiency of 99.9%, liquid level identification automatic high-pressure backwashing thorough sewage, to avoid secondary pollution.
2. Control methods and automation
   • Traditional filter: rely on manual operation, unable to individually control filtration and sewage, flushing and sewage synchronization, large water consumption.
   • Rotary drum microfilter: support intelligent regulation and control (such as cell phone APP control), backwash and sewage separation, can be set to rinse at regular intervals, water saving 30% or more.
3. Biochemical treatment capacity
   • Traditional filters: need to be equipped with a biochemical silo to cultivate nitrifying bacteria, but the filter material is easy to be clogged, and easy to fail if not properly maintained.
   • Rotary drum microfilter: integrated biochemical cultivation module, combined with the function of circulating oxygenation, to maintain the ecological balance of microorganisms, higher stability.

III. Post-maintenance costs

1. Conventional filters
   • Regular manual cleaning of filter media (e.g. brushes, filter cotton) is required, which is time-consuming and labor-intensive, and maintenance costs are high.
   • Pipes are easily clogged, requiring frequent inspection of pre-embedded piping and complicated maintenance at a later stage.
2. Rotary Drum Microfilter
   • Fully automatic backwashing + automatic drainage design, no need for manual intervention to clean the filter media.
   • Integrated structure, low failure rate, only need to check the nozzle and motor regularly.

IV. Cost-performance analysis

1. Initial input costs
   • Traditional filters: Higher total cost of civil construction, filter material and labor (about 1.0~15,000 RMB/10 tons of water).
   • Rotary drum microfilter: higher unit price (about 20,000 yuan/unit/20 m³ water body), but the overall difference is small by eliminating the cost of civil construction and piping.
2. Long-term cost of use
   • Traditional filter: large consumption of water and electricity (especially sewage water consumption), frequent replacement of filter material, average annual maintenance cost of about 2,000 to 3,000 yuan.
   • Rotary drum microfilter: water and electricity saving (low pressure operation), screen life of more than 5 years, average annual maintenance cost is less than 500 yuan.

V. Consolidated recommendations

• Applicable Scenarios:Traditional filters are suitable for users with limited budgets, small fish ponds and those who can accept regular maintenance; rotary drum microfilters are more suitable for medium to large fish ponds, scenarios that seek water quality stability and low maintenance costs.
• Technology Trends:Intelligent, integrated equipment is gradually replacing traditional filtration, especially in water and energy saving and long-term cost-effective advantages.
