Principle of operation
The principle of AQUACHLOR devices operation consists in humid gaseous oxidants mixture synthesis of sodium chloride solution which is loaded in doses into plants reactor with the help of membrane pump, this process being carried out under pressure of 0,8 to 1,2 kilogram-force/cm2 in reactors anodic chambers constructed of FEM-7 elements equipped with ceramic zirconium-oxide diaphragms. Water solution of non-iodinated dietary salt, for example, of one that complies with GOST R (State Standard) 51574, having concentration of 200 - 250 g/l, is used in AQUACHLOR devices as parent sodium chloride solution.
Simultaneously with gaseous oxidants mixture there is approximately 0,7 kg of sodium hydroxide (NaOH) generated in the form of solution having concentration of 150 – 170 g/l, along with 17,5 grams of hydrogen, which is discharged via special hose out of the premises area where an AQUACHLOR device is installed.
Immediately after formation, gaseous oxidants mixture, via fluoroplastic tubes and through pressure regulator, comes into ejector mixer where this mixture is dissolved in water flowing through the plant and turns into water solution of oxidants mixture having concentration of 0,5 - 1,5 g/l. This fact, as well as low volume of gaseous electrolysis product (less than 100 ml in one AQUACHLOR-500 module), ensures safe AQUACHLOR devices operation and absence of risk of maintenance staff and ambient medium poisoning with uncontrollable gaseous oxidants mixture release. The technology of gaseous oxidants mixture synthesis in AQUACHLOR devices eliminates the possibility of its accumulation or storing. If hermiticity of AQUACHLOR device reactor is broken this could lead to instantaneous interruption of gaseous oxidants generation process. Furthermore, AQUACHLOR devices construction provides for their automatic shutdown in case there occurs interruption in water flow delivery through the plant from pressure water-supply line.
Oxidants mixture solution generated in AQUACHLOR devices could be supplied to processed water flow either by means of direct loading (via existing chloric water loading line, via specially laid pipeline made of polyvinylchloride, polyethylene, polypropylene), or through accumulating reservoir.
Sodium hydroxide (caustic soda) solution can be used for coagulant solutions preparation, as a reagent for harsh salts precipitation during parent salt solution preparation, and as an efficient washing agent (requiring dilution), as well.
It is recommended that AQUACHLOR devices are operated in standard chlorination premises or in any other heated premises equipped with combined extract and input ventilation characterized by single air replacement within the premises volume per hour. Premises equipping with pressure water-supply line, sewage drain, electric plug socket of 220 Volt, “Europe” type, with capacity of up to 1,2 kWatt (for one AQUACHLOR-500 device module), is compulsory. Hydrogen which is formed during oxidants mixture solution generation shall be discharged from the premises area with the help of a hose connected with gas separator of AQUACHLOR device.
AQUACHLOR devices are alternative compact and high-performance source of oxidants mixture, and they could be used at water purification stations of household and drinking water-supply systems, at local water purification stations, at residential and industrial waste waters treatment plants, in the swimming-pools water purification systems as a substitute for balloons and containers with liquid chlorine and as chlorinators themselves, being applied either in the form of isolated modules, or as a group of modules united in a uniform hydraulic system having predetermined productivity by oxidants – from 30 grams per hour to hundreds of kilograms per hour.
