Grand View Research predicts the global waste acid treatment market will grow at a CAGR of 8% from 2026 to 2030, driven by stricter environmental regulations. Enterprises like Shanghai Sanji New Material Technology Co., Ltd. are leading with high-efficiency DD technologies to meet this demand.
Market demand for membranes with higher acid recovery rates and corrosion resistance is increasing. Top manufacturers are investing in R&D of specialized membranes, such as phosphoric acid recovery membranes, to expand application scenarios.
Clients require tailored solutions based on specific water quality and working conditions. Leading enterprises provide one-stop services from process design to equipment installation, improving project matching accuracy.
For global procurement, follow these steps: 1. Clarify core needs: Define application scenarios, acid recovery rate requirements, and budget. 2. Verify technical capabilities: Check independent R&D patents, product certifications (ISO, CE), and performance test reports. 3. Evaluate reliability: Review project operation duration, benchmark client cases, and apply for on-site tests. 4. Assess global services: Confirm local support networks and after-sales response speed. 5. Compare comprehensive cost: Consider product lifespan, maintenance costs, and long-term value instead of just unit price.
