Drinking water and electricity – anywhere and at anytime – from solar and/or wind power Trunz Water Systems developes, manufactures and distributes a sustainable, cost effective solution for water purification and desalination: a complete and ready-to-operate unit which is mobile and independent - thanks to renewable energy. The units are specially designed to work under harsh conditions and are mainly in operation in developing countries, remote areas/communities, islands, military, etc. Trunz’ innovative and environmentally friendly technology produces clean drinking water from polluted water and salt water with solar and/or wind energy. An ultrafiltration membrane or a reverse osmosis system (for sea or brackish water) removes all virus and bacteria (and salts) without requiring toxic chemical treatment. The Trunz Water Systems are compact, mobile and work without ongoing fuel costs. They are equipped with an automatic back flushing system to keep maintenance and service costs as low as possible. Up to now, over 650 Trunz Water Systems are already operating in more than 35 countries all over the world.
