Silica removal package

The Silica Removal Package (SRP) offers the best protection for boilers and turbines. By removing colloidal silica (>99.8%) from the (surface) feedwater, it limits equipment failure, maximizes uptime of power generators, and increases overall operational efficiency.

Features

  • >99.8% colloidal silica and >95% bio-polymers (TEP) removal
  • Single process step with minimal pretreatment required
  • Low energy consumption
  • Standardized design from 10 to 120 membane modules per skid with a small footprint
  • Chemically enhanced backwash
  • X-Flow HFS60 membrane modules with proven track record and a tight molecular weight cut-off (MWCO) of 10,000
  • Capable of either dead-end or crossflow filtration
  • High chemical resistance (high chlorine tolerance and wide pH range)

typical use

The buildup of scaling from colloidal silica in turbines, evaporation systems and rotating machines is a major and costly problem in many industries, due to unnecessary downtime, extra maintenance and the need for anti-scaling chemical additives. The SRP reduces colloidal silica, maximizes boiler efficiency, and significantly reduces the number of plant shutdowns. With a silica removal rate ten times higher than standard UF, no need for coagulants, and membranes used for pretreatment instead of polishing, the SRP’s efficiency offers the best possible protection for boilers and turbines.


The SRP can remove 99.8% of colloidal silica in a single process step,  making it possible to meet the silica limits for high-pressure boilers and thereby maximize efficiency. The robustness of the X-Flow HFS60 membrane module allows for installation upstream of a reverse osmosis system or an ion exchange system.
