Softening Resin ProSoft™ Fine Mesh
ProSoft Fine Mesh — We took our premium grade resin and reduced the partical size for faster kinetics and regeneration. ProSoft Fine Mesh is ideally suited for cabinet style softeners and for use with ProSelect™ Tannin for a mixed bed softener/ organic removal unit. You won't have any problems here with fines or color throw, because we have already prewashed and rinsed the resin for you.

BACKWASH — The graph above shows the expansion characteristics as a function of flow rate at various temperatures.
ProSoft Fine Mesh is an 8% crosslinked cation resin optimized for industrial softening applications. It has higher total capacity than standard crosslinked resins such as ProSoft Gold and has higher operating capacity when relatively large brine doses are used during regeneration. ProSoft Fine Mesh is suitable for hot water applications and for waters that contain modest levels of chlorine.

ER10003 Hardness Leakage Graph
CAPACITY AND LEAKAGE — Capacity and leakage data are based on 2:1 Ca:Mg ratio, 500 ppm TDS as CaCO3, 0.2% hardness in the salt, and 10% brine concentration applied co-currently through the resin over 30 minutes. No engineering downgrade has been applied.
Iron Removal
ProSoft Fine Mesh has good capacity for iron removal. Soluble (ferrous) iron is removed by ion exchange, in much the same way as hardness ions are removed. Particulate (ferric) iron is removed by filtration. As a general rule of thumb, to protect against fouling, the iron content in the feedwater should not be more than 1 mg/L Fe per each 17 mg/L of hardness. This ensures an adequate salt dose and frequent regenerations which help prevent fouling.
