Ceramic Softening Filtration for Beverage Processing

The feed water is a blend of municipal and borehole water with different properties. Sudden and strong peak events led to damage of the previously installed polymeric membrane system.

Variable water quality from blended sources caused frequent membrane damage with polymeric systems. High variation in hardness levels and unpredictable peak events required a robust solution.

CERAFILTEC's softening filtration enables operation with varying water properties. Lime is dosed to pH 9.6 to reduce calcium hardness. During peak events, lime overdosed to pH 10.5 to reduce magnesium hardness.

Stable long-term operation achieved regardless of total hardness level. All precipitants transferred to ceramic flat-sheet membrane without settling step, ensuring reliable beverage-grade water.
