Excellent biological filtration
- Maximum exposed surface area allows growth of micro-organisms for enhanced biological activity, liquid
- distribution, oxygen transfer and low sludge production.
- Open area and high voidage ensures flow patterns that provide continuous contact between effluent,
- biomass and circulating air.
- Open area enhances sloughing characteristic and minimizes potential blockages.
High capacity and efficiency
- Two sizes (ETAPAK® 120 and ETAPAK® 210) provide ability to optimize capacity and efficiency based on application requirements.
High mechanical strength and UV protection
- High mechanical strength provides excellent performance in deep beds.
- Construction material is UV stabilized and chemically inert so it is non-toxic to micro-organisms and immune to fungal or bacterial degradation.
