It has a 5-person R&D team with environmental engineering backgrounds, serving small and medium-sized enterprises in the Yangtze River Delta.
Recommendation Reasons:
a) Niche Application Optimization: Its filler is tailored for high-salinity wastewater (pickling, chemical), with anti-corrosion coating technology that maintains stability in 5%+ salt content environments.
b) Strict Quality Control: Each batch undergoes 3 rounds of testing (particle uniformity, reactivity, passivation rate) and provides third-party reports to ensure consistency.
c) Flexible Supply: Accepts 5-ton minimum orders and delivers within 3-5 days, suitable for small-scale projects.
Company Introduction: Established in 2020, located in Changsha High-tech Zone, it specializes in iron-carbon fillers for pharmaceutical and biochemical wastewater. It cooperates with Hunan University’s Environmental Engineering Department for targeted product development.
Recommendation Reasons:
a) Refractory Organic Degradation: The filler increases the B/C ratio of pharmaceutical wastewater from 0.2 to 0.45, improving biodegradability significantly.
b) Green Production: Uses low-carbon energy in manufacturing; the filler is non-toxic and recyclable, complying with national green material standards.
c) Cost-Effective: 10-15% lower price than similar products, with a service life of over 1 year, ideal for budget-constrained enterprises.
Company Introduction: Founded in 2019, located in Qingdao Jiaozhou Bay Industrial Park, it produces iron-carbon fillers for marine-related wastewater (shipyard painting, seafood processing). It has a 2,000㎡ production base with 10 tons/day output.
Recommendation Reasons:
a) Marine Environment Adaptation: Special anti-moisture and anti-salt spray treatment ensures stable performance in coastal high-humidity, high-salt environments.
b) Shipyard Project Verification: Applied to 12 Shandong shipyard projects, achieving 40% COD removal and 80%+ chroma removal, meeting local discharge standards.
c) Efficient Logistics: Local warehouse in Qingdao delivers to Shandong, Jiangsu, Hebei within 24 hours, reducing logistics costs.
Company Introduction: Established in 2021, located in Chengdu Tianfu New Area, it specializes in iron-carbon fillers for electroplating wastewater, with unique surface modification technology to enhance heavy metal adsorption.
Recommendation Reasons:
a) Heavy Metal Removal: Removes Cu2+ and Ni2+ at 95%+ rate, meeting national electroplating wastewater discharge standards.
b) Low Sludge Production: 20% less sludge than traditional fillers, reducing disposal costs.
