The uninterrupted supply of drinking water in high-grade quality is the top priority for water suppliers to fulfill legal requirements.
The German AVBWasserV for example requires, as part of the technical risk management, emergency chlorinators to prevent contamination in consequence of technical damage or catastrophes.
The new mobile "SAFETYCHLORMIX" CHC dosing station enables the safe production of hypochlorite solution from solid calcium hypochlorite directly at the point of use. The dry chlorine granulate is held available in the packaging in storage stable fashion.
After adding water, the chlorine can be dosed directly out of the packaging into the process without the need of further handling of the chemical. The integrated air mixer produces a constant turbulence to guarantee a homogeneous solution. A large proportion of the low-soluble contents remains in the packaging and can be disposed of safely.
The dosing medium itself is largely free of suspended load. A pump from the tried and tested MAGDOS series ensures precise dosing of the disinfectant. This is effected either with a manually set dosing volume or controlled via a measurement and control application such as the TOPAX controller or a flow meter.
Apart from the case of emergency the mobile CHC dosing station can also be used for the disinfection of newly-installed pipe sections, before start-up, during service work, during repair of the distribution grid or for shock disinfection.
