The Aquastat Micro-Discharge Process improves water efficiency and saves money
Aquastat, one of the country's leading water treatment specialists is fitting a simple device to cold water systems to prevent the build-up of scale without the use chemicals or salt.
The resulting increase in flow considerably improves the efficiency of water systems, but because it uses no chemicals and consumes negligible power, operating costs are insignificant.
The Aquastat Micro Discharge Unit (MDU) treats water physically by pulsating electrical discharges which interfere with the polarity of the dissolved scale-forming salts.
Suitable areas for applications fall into 2 main categories: once-through systems, such as calorifiers and hot-water boilers; and vented recirculating systems, including cooling circuits for air-conditioning plant.
The two illustrations show micrographs of samples of the same water magnified approximately 800 times. The even dispersion of small particles in the treated sample prevents agglomeration of the particles into hard, adherent scale.
How it works
The process unit is simply fitted into the cold water pipe, requires no off-sets in the pipe line and places no restriction on water flow. The water flows in fine individual streams through a perforated Monel electrode. This is the anode of the unit and imparts a controlled micro-discharge to each stream. The level of current is automatically adjusted by the electronic control unit for the volume and quality of the water flow.
The controlled minute electrical discharges applied to the water interfere with the polarity of dissolved scale-forming salts. This negates their potential to crystallise into the stereo-chemical patterns of adherent scale.
