Design Specifications

Aquatabs Flo is an automatic chemical disinfection unit mainly used in a community setting.  It can be integrated into the reservoir at the point of entry and release a precise dose of chlorine automatically. The water flows past the cartridge of solid chlorine tablets which are slowly eroded by the flow of water, thus disinfecting the water. The chlorine disinfectant tablets inside the cartridge integrate into gravity-fed water treatment systems hence operating without the need of power. Residual chlorine keeps the water safe as it is stored and used. Furthermore, it purifies 180 m³ liters of water per cartridge. The design specifications include: Weight 0.11 kg Dimensions 10 × 30 × 4 cm
