| Ecomedia is a spherical material with a high
wear-resistance. It is a new material best suited for a filter media. It
is used for filters for industrial wastewater treatment in POSCO, INI Steel,
Hanbo Steel, and so forth. Its SS removal rate is better than the conventional
filter sand. Recently, the filter gravel (5 to 10mm, 10 to 25mm, 25 to 35mm)
has been developed and is supplied along with the filter media. PS Ball
with a size of 0.1 to 4mm is used for Ecomedia. |

 |
Uniform and almost spherical filter media (uniformity coefficient
= 1.22 [sand:1.64], shape coefficient = 1). |
|
Long filter media use due to high strength and low abrasion. |
|
High SS and organic materials removal efficiencies (10 to 20% higher
than sand). |
|
High water flow rate (30 to 40% higher than sand). |
|
High turibity removal efficiency small and uniform filtermedia (0.1mm
to 0.6mm)
(for membrane pretreatment or high-level filtration). |
|
Environment-friendly (uses steel-making slag wastes). |
|
Filter media replaceable without modifying the conventional sand
filter. |
