wastewater treatment 3d model

A simple wastewater treatment plant (WWTP) model designed for 3D printing. Include only basic geometric shapes. Add the following elements in a clean, minimal layout: A small rectangular box with vertical bars (screening unit). A shallow rectangular tank (grit chamber). A circular tank with a conical bottom (primary clarifier). A large rectangular tank with smooth walls (aeration tank). A second circular tank with a central cone (secondary clarifier). A small rectangular box (sludge drying bed). A narrow straight channel (disinfection). A simple pipe or small channel as the final effluent outlet. Use simple, smooth surfaces, no fine details, and keep the model compact and easy to print.*
