While Selcoperm, brought to you by Grundfos , was designed predominately for the swimming pool market because it offered a safe way to produce sufficient disinfection, the technology is ideal for small to medium town water supplies,especially in remote areas where there are limited chemical deliveries available.
Key components of the Selcoperm unit include an electrolysis system, storage tanks for the saturated salt solution and product solution, an exhaust fan for removing any hydrogen produced, and dosing pumps for the product solution. The concept is rounded off with a measuring and control unit for
chlorine dosing.
The electrolysis system is supplied as a turn-key solution. Only the pipework for the water supply, the connections of the salt and product storage tanks and the exhaust pipe have to be installed. The size of the storage tanks depends on the capacity level of the system and the amount of disinfectant solution required.
The benefits of the electrolytic chlorination method include:
• Common salt is the base material – it is nontoxic and easy to store.
• Only water, common salt and electricity is needed for the electrolysis – low operating costs,
world-wide use.
• Fresh hypochlorite is always on hand – the disinfectant solution does not dissociate like
commercial hypochlorite solutions. Lower formation of chlorate as a by-product.
• Approved disinfection method complying with the DWI drinking water regulations – an
alternative with less safety requirements to chlorine-gas-based systems.
• Robust and elementary components – low-maintenance and a long service life, compared with
the membrane cell electrolysis.
Selcoperm effortlessly handles peaks in demand because the disinfectant generated can be very easily stored in buffer tanks for long periods of time.
The benefits include:
• No transport, storage or handling of disinfectants.
• No formation of unwanted by-products.
• Cost-effective use of common salt as a base material.
• On-site generation precisely according to your requirements.
