Showerloop: Water filtration and purification system
Showerloop is a water filtration and purification system that recycles shower water in real time allowing you to shower with hot water for a long time but only use 10 liters of water per shower (normal shower = ~6-10l/min) and a fraction of the energy (around one tenth) compared to a normal shower. The device can be installed inside or outside of a shower stall or bathtub. The main components are a pump, sand and activated carbon filters and a UV-lamp. The system weighs around 20kg and is made from transparent acrylic, steel or plastic pipe connectors and copper, plastic or rubber tubing.
The filters can last as long as two years (but more like 1 year) with daily use but depends on the behaviour and general dirtiness of the user/s. The sand filter can be washed, the activated carbon or AC can be regenerated but only at high temperatures > 500 degrees C or composted and the UV lamp should last for thousands of hours but can be recycled and replaced like any other CFL.
The basic build of Showerloop is incredibly modular in terms of placement, materials selection and aesthetics. The only constraints come from the ideal filter dimensions and the power output of the UV lamp both of which are explored in the bachelor thesis [https://www.theseus.fi/handle/10024/76148 ShowerMagic : A Hygienic and Eco-Efficient Real Time Greywater Reuse System for Showers].
