Case Study: Intensive RAS Shrimp Hatchery Upgrade
Application: Land-Based Recirculating Aquaculture System (RAS) Nursery Tanks
A 200-tank indoor shrimp hatchery faced frequent algae buildup on PP tank walls, requiring over 16 labor hours of daily cleaning and affecting larval growth performance.
Traditional PP liners developed algae biofilm within days in nutrient-rich RAS environments. Frequent scrubbing increased labor costs, stressed shrimp larvae, and risked damaging tank surfaces.
Algae Biofilm & Larval Mortality Risk
Integrated Anti-Algae Co-Extrusion & Full RAS Piping Retrofit
Anti-algae PP sheets reduce biofilm buildup, cutting manual cleaning needs by over 80% without harsh chemical treatments.
Co-extrusion technology integrates anti-algae agents throughout the sheet for durable protection in continuous immersion environments.
Pain Points & Strategic Solutions
Algae Biofouling
Nutrient-rich RAS environments accelerate algae growth on traditional PP tank surfaces. Frequent manual cleaning increases labor costs, risks tank damage, and stresses aquatic livestock.
QEEHUA anti-algae modified PP sheets use integrated biofouling protection technology to reduce algae attachment and cut cleaning frequency by over 80%, creating a cleaner and healthier aquaculture environment.
Water Quality Protection
Made from 100% virgin PP resin with no recycled content, ensuring safe, clean water conditions without harmful substance release.
Food Safety Compliance
Materials comply with RoHS, REACH, and food-contact standards, providing reliable safety and full material traceability for aquaculture applications.
Cost-Effective Circulation
Chemical-resistant UPVC pipes and valves provide reliable water circulation performance with a complete range of fittings for RAS systems.
Smooth internal surfaces reduce scaling and biofilm buildup, maintaining consistent flow efficiency throughout the circulation system.
Industry Requirements
Anti-Algae Durability
Co-extrusion technology integrates anti-algae agents throughout the PP sheet for long-lasting biofouling protection in continuous RAS environments.
100% Virgin Resin
Made from 100% virgin polypropylene resin with no recycled content, ensuring safe water conditions and reliable aquaculture performance.
RoHS / REACH / Food-Grade
Certified materials meet international safety standards for chemical control and food-contact aquaculture applications.
Chemical-Resistant Piping
UPVC and PPH piping systems provide excellent resistance to ozone, chlorine, and water treatment chemicals for stable RAS circulation.
