How Do You Remove Silica from Industrial Water and Wastewater?

Feb 14, 2020Common methods of silica removal for colloidal silica include ultrafiltration (UF), flocculation, and clarification. Ionic silica Ion exchange (IX) is a process where a stream is passed through a resin substrate that facilitates removal of ionic contaminants, and replacement with similarly charged particles.

Removing silica from power plant water News The

While power plants already recycle fresh water, the number of times it can be reused is limited by the amount of naturally-occurring silica that accumulates with each cycle. Buildup can disrupt equipment function, but current silica removal methods can cost 1.5–2 times more than simply using fresh water.
