PP Welded Aquaculture Tanks: A New Eco-Friendly and Safe Choice for Modern Aquaculture 2025-12-31 PP Welded Aquaculture Tanks: A New Eco-Friendly and Safe Choice for Modern Aquaculture Amid the wave of transformation towards intensive and intelligent aquaculture, PP welded tanks are becoming core equipment for industry upgrading, thanks to their unique material advantages and structural characteristics. These tanks, made from polypropylene (PP) as the base material and seamlessly joined through hot-melt welding technology, not only address the pain points of traditional tanks—such as susceptibility to corrosion and high maintenance difficulty—but also achieve comprehensive breakthroughs in environmental friendliness, cost-effectiveness, and functionality. 1. Corrosion Resistance: Solving Water Quality Pollution Challenges PP sheets far exceed traditional concrete and metal tanks in their tolerance to acids, alkalis, salts, and microorganisms. The stable carbon chains in their molecular structure effectively resist erosion from corrosive substances in water, such as ammonia nitrogen and hydrogen sulfide. Experimental data show that PP sheets can maintain structural integrity even in extreme water environments with pH levels ranging from 2 to 12, with a service life of over 10 years. For example, after a whiteleg shrimp farm in Guangdong adopted PP welded tanks, the corrosion rate of the tank bodies decreased from 0.3 mm per year in traditional concrete tanks to 0.02 mm, completely eliminating the risk of cross-contamination caused by tank leakage. 2. Modular Design: Reconstructing Aquaculture Space Efficiency PP welded tanks are produced using standardized modules and can be assembled quickly, much like building blocks. The dimensional accuracy of individual sheets is controlled within ±1 mm, and seamless connections are achieved through welding, reducing construction time by 70% compared to traditional concrete tanks. An industrialized aquaculture base in Yancheng, Jiangsu, customized circular tanks with a diameter of 12 meters and a depth of 2 meters using the malleability of PP sheets. Combined with a recirculating aquaculture system (RAS), the yield per unit area increased to four times that of traditional ponds. Notably, the modular design supports flexible expansion and relocation of the tanks. One enterprise increased its original aquaculture scale by 30% within 48 hours by adding PP modules, fully demonstrating its adaptability to market fluctuations. 3. Environmental Performance: Practicing Green Aquaculture Principles As a food-grade eco-friendly material, PP sheets are produced without the addition of heavy metals and are recyclable after disposal. Compared to concrete tanks, PP tanks eliminate the need for plastic products like impermeable membranes, reducing microplastic pollution at the source. After adopting PP sheets, a grouper farm in Fujian saw a 42% reduction in total phosphorus content in the water, with aquaculture effluent meeting discharge standards after simple treatment. Additionally, the low water absorption and smooth surface of PP sheets make them easy to clean, effectively preventing algae growth on the tank walls and reducing the use of chemical pond-cleaning agents. This provides a safer growth environment for aquatic products. 4. Economic Analysis: A Smart Choice for Long-Term Returns Although the initial cost of PP tanks is 20%–30% higher than that of concrete tanks, their advantages in lifecycle costs are significant. For example, in a 1,000-cubic-meter aquaculture tank, the annual maintenance cost of a PP tank is only one-fifth that of a concrete tank, with no need for periodic shutdowns for repairs. A tilapia farm in Shandong found that the energy consumption per unit yield of PP tanks was 18% lower than that of concrete tanks, the survival rate of aquatic products increased by 12%, and overall profits improved by 25%. More importantly, the standardized production model of PP tanks enables farms to quickly replicate successful practices. A chain aquaculture enterprise, by uniformly adopting PP tanks, reduced the construction period for new bases from six months to two months, significantly enhancing its market responsiveness.

PP module rainwater regulation and storage tank system 2025-11-05 The core advantage of applying the PP module rainwater regulation and storage tank system lies in high space utilization, shortened construction period, and reduced whole-life cycle cost. Meanwhile, it features environmental protection and flexible adaptability, which can effectively address urban waterlogging and water resource shortage. 1. High Space Utilization, Suitable for Complex Sites Traditional concrete water storage tanks require large excavation space and have high demands on site shape. The PP module adopts a modular splicing design, which can be flexibly combined according to the actual size of the site, and can even be adapted to irregular plots or narrow underground spaces of buildings. Compared with traditional concrete tanks, the PP module system can save about 30% of the floor area, making it particularly suitable for scenarios with tight land resources such as urban core areas and transportation hubs. 2. High Construction Efficiency, Significantly Shortening the Construction Period PP modules are factory-prefabricated products. On-site operations only involve foundation treatment, module splicing, and earth backfilling, without going through long processes like formwork erection, pouring, and curing required for concrete tanks. Data from practical projects shows that the construction period of the PP module rainwater regulation and storage tank is reduced by more than 50% compared with traditional concrete tanks. It can be put into use quickly, minimizing impacts on surrounding traffic and residents' lives. 3. Low Whole-Life Cycle Cost, Convenient Maintenance In the initial construction stage, the PP module system does not require a large number of labor forces or large-scale equipment, resulting in lower labor and machinery costs. In the later maintenance stage, its detachable and repairable characteristics avoid large-scale excavation during the maintenance of traditional concrete tanks. The PP material is acid and alkali resistant as well as corrosion resistant, with a service life of more than 30 years. It does not need frequent anti-corrosion treatment, and the whole-life cycle cost is about 20% lower than that of traditional concrete tanks. 4. Excellent Environmental Performance, Conforming to Green Building Concepts PP modules are mainly made of recyclable polypropylene materials. The production process generates low carbon emissions, and they can be recycled and reused after being discarded, reducing construction waste pollution. During the rainwater regulation and storage process, the system can be equipped with filtration and disinfection components to purify rainwater. The purified rainwater can be used for green irrigation, road flushing, etc., replacing tap water and saving a large amount of water resources for the project every year. 5. Strong Regulation and Storage Capacity, Effectively Alleviating Urban Waterlogging The gap rate between PP modules is high (about 95%), providing a large water storage capacity, which can quickly collect and temporarily store surface runoff during rainfall. In heavy rain, the system can reduce more than 85% of surface runoff, preventing rainwater from directly pouring into the municipal pipe network, significantly reducing the risk of urban waterlogging and ensuring the normal operation of traffic and residents' lives.
