Case Study: Intensive RAS Shrimp Hatchery Upgrade
Application: Land-Based Recirculating Aquaculture System (RAS) Nursery Tanks
A 200-tank indoor shrimp hatchery operating high-density nursery systems with 24/7 water recirculation. Daily cleaning of algae-fouled PP tank walls consumed over 16 labor hours, while residual biofilm compromised larval survival rates and slowed growth cycles.
Conventional PP tank liners developed aggressive algae biofilm within 7–10 days in nutrient-rich RAS water. Manual scrubbing consumed over 16 labor hours daily, stressed larval-stage shrimp, and risked scratching tank surfaces — posing a critical threat to hatchery economics.
Algae Biofilm & Larval Mortality Risk
Retrofitted all nursery tanks with QEEHUA anti-algae modified PP sheets manufactured through integrated masterbatch co-extrusion. The anti-algae agent is molecularly bonded into the polymer matrix, delivering 6–10 year anti-fouling efficacy. Paired with food-grade certified UPVC circulation piping and valves for the full water treatment loop.
Integrated Anti-Algae Co-Extrusion & Full RAS Piping Retrofit
Anti-algae modification agents prevent biofilm adhesion at the molecular level, reducing manual tank cleaning frequency by over 80% and eliminating the need for harsh chemical algaecides.
One-step masterbatch co-extrusion embeds the anti-algae agent throughout the full sheet thickness — not a surface coating. Effective algae suppression maintained for 6–10 years under continuous immersion.
Pain Points & Strategic Solutions
Algae Biofouling
Nutrient-rich RAS water promotes rapid algae colonization on conventional PP tank surfaces. Manual scrubbing is labor-intensive, risks surface damage, and stresses aquatic livestock during cleaning cycles.
QEEHUA anti-algae modified PP sheets use molecularly bonded biofouling inhibitors that prevent algae attachment. Reduces manual cleaning frequency by over 80%, protecting fry and juveniles from handling stress.
Water Quality Protection
100% virgin PP resin ensures absolutely zero heavy metal or harmful additive leaching into culture water. No recycled content means no risk of algae-toxin contamination or endocrine-disrupting chemical release.
Food Safety Compliance
Full compliance with RoHS, REACH, and food-contact material standards. Certified safe for direct contact with aquaculture species destined for human consumption. Full material traceability documentation included.
Cost-Effective Circulation
UPVC pipes and valves deliver exceptional chemical resistance against water treatment agents (ozone, chlorine, pH adjusters) at a competitive price point. Full range from DN15 to DN400 with matching PP/UPVC fittings.
UPVC and PPH piping systems maintain smooth internal surfaces that resist scale buildup and biofilm accumulation, ensuring consistent flow rates throughout the RAS water circulation loop without pressure loss over time.
Industry Requirements
Anti-Algae Durability
Integrated masterbatch co-extrusion embeds anti-algae agents throughout the full sheet thickness for 6–10 year efficacy under continuous RAS immersion conditions.
100% Virgin Resin
All PP sheets manufactured exclusively from virgin polypropylene resin. Zero recycled content eliminates heavy metal and toxin leaching risks that compromise fry survival rates and end-product food safety.
RoHS / REACH / Food-Grade
Certified to RoHS and REACH hazardous substance standards, plus food-contact material compliance for aquaculture species destined for the human food chain. Full documentation available.
Chemical-Resistant Piping
UPVC and PPH piping systems resist ozone, chlorine, pH adjustment chemicals, and common aquaculture water treatment agents without degradation, scaling, or biofilm accumulation.
