Ultrafiltration Revolution in Aquaculture | WECLEAN Ceramic Flat Membranes Empower 40% Operational Cost Reduction through Efficient Water Reuse

The Rise of Recirculating Aquaculture, Ceramic Membrane Technology as a Key Support

In recent years, recirculating aquaculture has gained increasing attention from enterprises as an efficient and water-saving farming model. Industry leaders such as CIMC, JD.com, and Gree have successively entered this field. This strategic move is not only a response to slowing growth in traditional industries but also an active effort to align with national policies on food security and sustainable water resource utilization. With the promotion of high-value aquaculture species and supportive technological policies, recirculating aquaculture has become a promising "blue ocean" industry.

In this trend, efficient recycling and reuse of reclaimed water has become a key technological link driving the industry's large-scale development. Through integrated processes such as "ceramic membrane + ozone catalysis" for treating aquaculture water, high-quality reclaimed water can be consistently obtained. This not only meets the growth requirements of aquaculture organisms but also significantly improves water resource utilization efficiency, supporting green and low-carbon development.

WECLEAN Ceramic Flat Membrane: A Reliable Solution from Wastewater to Aquaculture Water

WECLEAN ceramic flat membrane modules have been successfully applied in multiple recirculating aquaculture and wastewater reuse projects. By recycling treated water back into aquaculture systems, the technology's reliability and applicability in reclaimed water reuse have been validated.

Xinjiang Salmon Recirculating Aquaculture Project (100t/d)

This project treats salmon aquaculture wastewater, which undergoes biochemical treatment followed by deep filtration using WECLEAN ceramic flat membranes. The operating flux remains stable at 30 LMH, with the filtered water directly recycled into the aquaculture system.

The system has been operating continuously and stably for over three months, with effluent turbidity consistently below 0.1 NTU. The water is clear and transparent, fully meeting the high-standard water quality requirements for salmon farming. This not only improves the aquaculture environment but also significantly reduces water exchange costs.

Anhui Domestic Wastewater Reuse Project (60t/d)

This project treats domestic wastewater from a homestay, with the effluent used for landscape ponds and fish farming. The original system used organic hollow fiber membranes, which experienced severe membrane fouling and frequent membrane breakage within less than a year of operation. This led to unstable system performance, fluctuating effluent quality, and continuously rising maintenance costs due to frequent cleaning and replacements.

The system was later upgraded to WECLEAN ceramic flat membranes, operating at a flux of 30 LMH. Since commissioning, effluent turbidity has remained stable below 0.1 NTU, with clear water quality and stable operation, fully meeting the requirements for fish survival. This upgrade fundamentally addressed the shortcomings of the original organic membrane system in terms of fouling resistance, operational stability, and long-term cost-effectiveness.

Core Advantages of WECLEAN Ceramic Flat Membrane

→ Strong Fouling Resistance: The thin fouling layer on the ceramic membrane surface is easy to clean, significantly extending the cleaning cycle.

→ Stable Effluent Quality: Ultrafiltration-level precision and high-quality materials ensure long-term filtration performance, maintaining stable effluent turbidity.

→ Long Service Life of up to 15 Years: Greatly reduces replacement frequency and long-term operational risks.

→ Significant Reduction in Operating Costs: Although the initial investment is higher, the long lifespan and low maintenance requirements result in a significant cost reduction of 40%.

→ High Flux: The porous structure of the product combined with optimized flow channel design ensures stable high flux even under high suspended solids loads.
