Engineering Projects/Water Treatment
Idea edit
Build a functioning model of an egg digester. Egg digesters are a water treatment facility that captures all the gasses produced. Storm water and septic water are typically combined. When it rains the septic system is overloaded. If oil could be trapped from household septic systems, water treatment would be much more efficient. If urine was kept separate, the septic systems could be much more efficient. The process of treating septic water can yield posionous gasses, and gasses that can be used to generate electricity. Some water treatment facilities are net producers of energy.
