Purpose of PCG Bioreactor Development


1.The carrier is mainly applied to contact oxidation method, the traditional carrier has poor hydrophilicity and low oxygen dissolution efficiency;

2.The small specific surface area of traditional carriers, the attachment amount of microorganisms is small, and the treatment capacity is poor;

3. Reducing sludge discharge and environmental pollution;

4.Traditional MBBR carrier hanging wear equipment corrosion layer, reducing the mission life of sewage treatment equipment; the use of wear debris resulting in damage to pumps & fans.

Application Cases


Recirculating Aquaculture Water Treatment Project
This case involves a recirculating aquaculture water treatment project with a treatment capacity of 10,000 t/day.

Technology Empowerment


Ultra-High Bio-Load Capacity
Utilizing nano-level porous PCG hydrogel carriers with a specific surface area of up to 6,000 ㎡/m³ (3-5 times that of conventional carriers) and a porosity >95%, it supports composite microbial communities (nitrifying/denitrifying bacteria + probiotics). Biofilm formation speed is increased by 70%, enabling continuous and stable degradation of harmful substances such as ammonia nitrogen and nitrites.


Long-Lasting Self-Cleaning
The biomimetic hydrophobic coating on the gel carrier surface improves anti-organic clogging performance by 90%. Combined with a pulsed water flow flushing design, the filter media requires no replacement for up to 5 years, reducing maintenance costs by 60%.
Ecological Synergy and Efficiency
PCG carriers directionally release trace elements (e.g., potassium/selenium) through their micropores, enhancing the immunity of farmed species. Paired with the system’s UV sterilization module, the incidence of diseases decreases by 40%, and the survival rate of fish and shrimp exceeds 97%.
