Available from CST Wastewater Solutions , continuous sand filters are extremely efficient at removing fine solids, even colloidal particles. They are simple to install and feature a unique continuous back-washing system that utilises 50% raw water instead of filtered water.
The operation lead loss enables gravity feed in many circumstances and the continuous sand filters require low capital and have low operating costs.
All wetted parts of these filters are manufactured from stainless steel ASI 304, though other specialised constructions can be catered for on request. Maintenance of the filtration equipment is simple as the sand air-lift system is fitted on the outside.
Continuous sand filters are suitable for a wide range of applications including, but not limited to:
- Algae removal
- Surface water filtration
- Drinking Water treatment
- Municipal/industrial WWTP (primary and tertiary filtration)
- Pre-treatment for membrane ultra-filtration plant
- Pre-treatment for ozonisation treatment plant
- Biological denitrification
