Trunz Water Box 003 light – a water treatment plant for mobile or stationary use with external energy supply

The Trunz water treatment box TWB 003 light is the same unit as the standard TWB 003 but without feed pump. It provides approx. 1200 l of clean drinking water per hour from any non saline water source. The system includes automatic back flushing filtration and controls. An Ultrafiltration membrane removes all viruses and bacteria without requiring toxic chemical treatment. This process retains the natural minerals in the source water. The Trunz water box is ideal for decentralised water purification in remote communities, clinics, resort application etc. where power supply is already existing (without power supply : standard TWB 003). The system is very compact, easy to install and to maintain.


  • ideal for decentralised water purification
