Uses for glass in waste water filtration
The clogging or "biofouling" of sand filters in waste water treatment works is recognised as a major problem by industry. With impending EU legislation set to tighten discharge levels still further, many facilities now face a real risk of failing to meet the new standards.
Trials with recycled glass filter media have been in place since 1996, and have shown resistance to biofouling lasting many years. Without exception, the trials demonstrate that recycled glass filter media can cope comfortably with high solids loading to deliver 100% discharge compliance.
Main benefits:
- Exceptional performance over several years.
- Improved backwash efficiency, leading to reduced energy usage.
- Quick lifecycle payback.
