AQUACHLOR

AQUACHLOR-500M device, 2012

AQUACHLOR devices are designed to synthesize electrochemically activated high-efficiency concentrated solutions from sodium chloride solution:

  • disinfecting agent – a solution of oxidants mixture consisting of wet chlorine, hypochloric acid,  chlorine dioxide, ozone, and hydroperoxide oxidants, concentration of which is up to 600 g/h in equivalent of active chlorine;
  • cleaning and coagulating agent – a solution of caustic soda – sodium hydroxide solution of 160-180 g/l concentration.

AQUACHLOR devices offer a conceptually new process of electrochemical decomposition of brine – ion-selective  electrolysis with diaphragm.

AQUACHLOR-М devices – a new generation of compact, cost-efficient, safe, high-efficiency, eco friendly,  long-life, easy-to-operate electrochemical systems with the following capacities:

  • salt conversion rate 99.9%;
  • salt consumption per kg of oxidants in molecular chlorine equivalent – not over 1.8 kg; electric power consumption – not over 3.0 kW×h;
  • automatic reagent-free cleaning of electrochemical reactors;
  • automatic maintenance of oxidant concentration in disinfected water to a preset level.

2012: Six AQUACHLOR-500М devices
installed at a paper mill disinfect
80,000 m3 of water per day.

Oxidant solution is a functional analog of chlorine water and is used to disinfect water using a well-known technology of chlorine water application with any and all methods and means of control of disinfection process involved.  Due to block-modular design of devices it is possible to create the system of any capacity at manufacturing facilities of any layout. No design or special construction-assembly work is required. Chlorine cylinders are simply replaced with AQUACHLOR-M devices without changing hydraulic circuit of the chlorination plant.

AQUACHLOR devices and oxidant solution are completely safe which is confirmed by Rospotrebnadzor (Russian Federal Consumer Rights Protection Agency) and Rostechnadzor (Russian Federal Agency for Ecological, Technological and Nuclear Supervision) – there is no free volume of chlorine; all produced chlorine is diluted in water together with other products of anodic  oxidation of sodium chloride solution – ozone, hydrogen peroxide, chlorine dioxide – generating oxidant solution the disinfecting capacity of which is much higher than that of gaseous chlorine and many times as large as sodium hypochlorite.

Application:

  • water disinfection and treatment at drinking water supply stations,
  • domestic, industrial and agricultural wastewater disinfection,
  • water disinfection and treatment at swimming pools, balnearies and saunas,
  • wastewater disinfection in medical institutions, including tuberculosis facilities,
  • water disinfection at cooling water recycling systems of power utilities, chemical and metallurgical industry,
  • water disinfection in process cycles at industrial facilities, including food industry,
  • disinfection of medical waste before recycling,
  • water disinfection in offshore water spaces.

AQUACHLOR-M devices are serially manufactured by Delfin Aqua LLC manufacturing company as modules with capacity from 30 to 500 g of oxidant mix per hour.  AQUACHLOR-M devices are the most advanced of AQUACHLOR series and distinguish from previously developed by Vitold Bakhir AQUACHLOR models by original author’s solutions allowing to increase the output of gaseous oxidant mixture of one module from 500 to 600 g/h, with an additional unique option of automatic reagent-free cleaning of electrochemical reactors, permitting the device to operate continuously during a long period, as well as an additional option of automatic maintenance of oxidant concentration in disinfected water at a preset level.
