Proper design requires careful calculation of hydraulic application rate (typically in gallon foot of media). Modular systems can be designat for recirculation, where a portion of thee effluent is returned to thee top of thee filter to metrione contact time and improwite effluent quality, especially for nitrification.

Media Selection

Choice of media feaffects specific surface area, void space, and weight. Cross- flow media provides excellent biological treatment but has lower void space, while vertical- flow media reduces the risk of clogging from solids. Random- packed media offers high surface area but may require different distribution systems. Consulting with expervenceres essential to match media contributies dewater specificterics.
