Ceramic Membrane System for Fly Ash & Waste Salt Resource Recovery System

● Industry: Waste Incineration

● Client Need: Reduce landfill disposal, achieve resource utilization of waste salt derived from fly ash, and prevent environmental pollution - transforming waste into valuable resources.

Waste incineration facilities face mounting pressures from rising landfill costs for hazardous fly ash and increasingly stringent regulations on heavy metals and halogens. Our client, a waste management company in China, sought to convert high-chloride, heavy metal-laden waste salt - a byproduct of fly ash treatment - from an environmental liability into a compliant, reusable asset.

We designed and delivered a customized ceramic membrane system to address the complex purification requirements of refractory waste salt:

Material Superiority: Utilizing ceramic membranes' exceptional corrosion resistance and anti-fouling properties, the system operates reliably in highly corrosive, high-chloride environments where conventional polymer membranes would rapidly degrade.

Process Synergy: The system effectively removes suspended solids, colloids, and heavy metal ions from waste salt solutions, enabling subsequent nanofiltration and crystallization stages to produce industrial-grade recycled salt that meets stringent purity and safety standards.

Modular & Scalable Design: The skid-mounted ceramic membrane unit - featuring stainless-steel piping, automated control panels, and robust membrane housings - integrates smoothly into existing treatment infrastructure, allowing flexible capacity scaling as operational needs evolve.

Waste-to-Resource Transformation: Successfully converted waste salt into a high-purity industrial product, establishing a new benchmark for circular economy practices in solid waste management.

Environmental Compliance: Eliminated risks of heavy metal and chloride contamination, ensuring full adherence to rigorous environmental regulations and protecting soil and water quality.
