What is driving demand for customized Polyaluminium Chloride grades in China?
Customization is becoming the mainstream supply model for PAC. Producers are rolling out tailored formulations such as salt-tolerant grades for high-salinity wastewater and high-efficiency flocculants for low-temperature, low-turbidity water. These adapted products improve treatment fit by over 20% and can reduce dosing costs by 5-8% compared with general-purpose grades. The shift is moving from back-end formula adjustment toward front-end inventory: leading manufacturers now pre-stock region-specific formulations based on local water quality, so orders ship immediately without waiting for a production cycle. General-purpose PAC's share of spot supply is expected to keep declining as a result.
