Uranium removal using ion exchange columns. Discover how resin selection, operation parameters, and regeneration optimize recovery and wastewater treatment.

Gel resins lack permanent pores and rely on swelling in aqueous solutions to create channels, whereas macroporous resins possess stable, permanent pore channels. This structural difference leads to variations in performance—such as adsorption, fouling resistance, and regeneration—and determines which gold extraction processes are suitable for each type.

Anion exchange resin vs GAC for PFAS removal: compare costs, media life, system size and operating expenses.

In processes such as hydrometallurgical lithium extraction, lithium recovery from salt lakes, and lithium slag leaching, raw materials undergo leaching and neutralization reactions before being fed into a clarifier for solid-liquid separation. Suspended solid particles settle to the bottom to form sludge, while the clear liquid in the upper layer continuously overflows; this liquid is known as clarifier overflow.

Semiconductor ultrapure water ion exchange resins control ppt-level trace ions, TOC, and metals to boost advanced node device yield and reliability.

During actual long-term operation, many users encounter issues such as a continuous decline in resin softening performance, effluent hardness exceeding limits, and inconsistent softening results. Even when regeneration is performed on schedule, the treated water quality fails to meet standards; this directly impacts the operational efficiency of the entire water treatment system and increases equipment maintenance and operating costs.
