Sewage Treatment Plant - Trickle Filter

A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of some material, such as rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media, over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media. Aerobic conditions are maintained by splashing, diffusion, and either by forced-air flowing through the bed or natural convection of air if the filter medium is porous. The treatment of sewage or other wastewater with trickling filters is among the oldest and most well characterized treatment technologies.

This 3D design fits with any Modern wargaming tabletop setting, Diorama or Dolls House.

This STL file set is printable on Resin 3D printers, such as the Elegoo Mars. Print the model will 3D print with a 0.02 to 0.05mm layer height for best results.
An FDM 3D printer (like the Creality Ender 3) can be used but you may compromise the detail and result.

Supports are required for this STL model.
