Waste water and Industrial Water Filtration

Expertly sized active container glass sand for large filters that provides outstanding water clarity and quality – a direct and better replacement for silica sand in primary and secondary effluent treatments .

 

For Industrial Water Treatment. CS Active glass sand not only works with the same effluent quality, but outperforms silica sand in generating smaller clean-bed head and clogging head loss. Ideal for industrial and environmental water facilities, Cool South glass sand ensures better water treatment.

Independent Research A study conducted in Oswego, New York State, USA, evaluated the use of recycled container glass as a filter medium in wastewater collection, treatment, and disposal for a wastewater plant. The performance of the wastewater treatment facility was extensively monitored for a 16 week period, and a series of physical tests were performed on samples of both the glass sand and silica sand used for intermittent sand filters. The physical tests included acid solubility, magnesium sulfate soundness, and permeability. Researchers found the weight loss of the glass filter media was significantly less than that of the silica sand in identical tests for both acid solubility and magnesium sulfate soundness. Furthermore, the glass sand outperformed the silica sand media in permeability and durability, and was deemed more economical and mechanically superior.

In addition, the study also noted that small towns in New York still using natural sand were having to routinely replace the media in their filters due to clogging issues which would not be as frequent if glass sand was used.

Independent Research In a field study performed by the Clean Washington Center, USA, researchers replaced 900kg of silica sand from three high-rate filters with recycled glass and analyzed the results for approximately nine months. This is what they found: Less water: The average duration of backwashing (in minutes) was 2:34 compared to 3:21 for sand. That’s equates to a 23-percent reduction in water. The lighter glass material floats more easily, the study noted, allowing it to fluidize quicker, reducing backwash runtimes. Clearer water: The study showed a 25-percent reduction in National Turbidity Unit Readings. Energy savings: Porosity was better and recirculation systems could be operated fewer hours. Product volume savings: Approximately 20% less glass sand (by weight) is required for filtration.
