Waste Salt Resource Utilization: From "Waste" to "Wealth"

Today, a silent revolution is emerging — one focused on the resource recovery of waste salts. The goal is to convert salts extracted from wastewater into valuable chemicals like acids and bases, thereby realizing a truly circular economy.

Key Challenges:

 
Purity vs. Marketability: Sodium sulfate often has a purity below 92%, while sodium chloride lags below 95%, with insufficient whiteness, making them unsuitable for use in major industries like chemicals and construction.

Lack of Economies of Scale: Most ZLD systems produce only 1–5 tons of salt per day, which is too little to form stable supply chains, making downstream customers reluctant to purchase.
