Chlorine dioxide generator from 8 to 20 g/h

The LOTUS system produces, doses and controls Chlorine Dioxide for water disinfection.
Chlorine Dioxide is produced from diluted base chemicals: acid-chlorite process by Hydrochloric Acid (HCl 9%) and Sodium Chlorite (NaClO2 7,5%).
Chlorine dioxide produced by LOTUS is set to be proportional to the circulating water flow or based on a set-point – it is then dosed into the water flow.
There is no storage of chlorine dioxide hence no chlorine dioxide gas or concentrated solutions exist outside of the process application.
LOTUS is designed so that the reaction to produce chlorine dioxide takes place in a reaction chamber.
Multi function valves on the injection points ensure the security of the reaction chamber.
The base chemicals are stored in tanks and fed into the reaction chamber through suction lances.
Integrated level switches automatically stop the pumps when the tanks are empty.

Chlorine dioxide generator

The chlorine dioxide generator DIOX-A 10 was designed for the preparation of small quantities of chlorine dioxide.
As starting chemicals for the preparation of chlorine dioxide Cedolyt A9 (dilute hydrochloric acid, 9 %) and Nadolyt C7.5(dilute sodium chlorite, 7.5 %) are used.
Both solutions are fed from standard carboys directly into the reaction tank where the sodium chlorite and the hydrochloric acid are converted into chlorine dioxide.
Chlorine dioxide is a powerful disinfectant and oxidising agent, excellent at destroying odours.
Chlorine dioxide has been found to be superior to chlorine as a disinfectant.
This chemical has a higher oxidising reduction potential than chlorine and can achieve destruction of such organic substances and virus which are not attacked by chlorine.
At identical concentrations the capability of chlorine dioxide to destroy spores and virus is higher than that of chlorine.
The use of chlorine dioxide eliminates the formation of undesirable or harmful trihalomethanes (haloforms).
Chlorine dioxide oxidises unpleasant pollutants such as phenols, algae and products resulting from their decomposition into neutrally tasting substances.

Acid/chlorite process using dilute reagents

The Wallace & Tiernan Chlorine dioxide generator DIOX-A was developed for the preparation of chlorine dioxide up to a capacity of 250 g/h.
As basic chemicals for the generation of chlorine dioxide this unit uses Cedolyt A9 (dilute hydrochloric acid, 9 % HCl) and Nadolyt C7.5 (dilute sodium chlorite, 7.5% NaClO2).
Both reagents are metered directly from commercial carboys or intermediate storage tanks into the reaction tower where a chlorine dioxide solution is produced.
The strength of the two basic chemicals is balanced in a ratio that ensures an optimal yield of chlorine dioxide.
The chlorine dioxide solution produced is directly metered via an injection unit into the water to be treated.

 

Chlorine dioxide generator acid/chlorite process

The Wallace & Tiernan chlorine dioxide generator type DIOX-A 5000 was developed for the preparation of 2500 resp. 5000 g/h chlorine dioxide.
It produces an aqueous solution of chlorine dioxide of a constant strength.
As basic chemicals for the generation of chlorine dioxide this unit uses commercial grade hydrochloric acid (30 – 38% HCl) and Nadolyt C25 (sodium chlorite, 24,5% ClO2)

 

Chlorine dioxide generator Chlorine activated process

This type of unit uses Nadolyt C25 (sodium chlorite, NaClO2) and chlorine gas (Cl2) as the basic chemicals for the generation of chlorine dioxide.
Nadolyt C25 is metered into the unit directly from a carboy or a pumped system.
Three system types are available for capacities of 1500, 3000 or 4500 g/h chlorine dioxide.
Chlorine dioxide solution is produced in the reaction tank.
Once the chemicals have fully reacted, the concentrated chlorine dioxide solution is diluted with water at the reactor outlet before it is passed to the chlorine dioxide storage tank.
The quantity of the dilution water is adapted to the required strength of the chlorine dioxide.
This is adjusted to1 up to max. 3 g / l ClO2 depending on the demand.

 

Oxiperm OCG-166 systems generate 0.75 to 10 kg/h of chlorine dioxide directly on site according to the proven sodium chlorite/chlorine process.
The produced chlorine dioxide solution in the batch tank has a concentration of 3 g/l.
Usually, disinfection is the first step of pathogen reduction, in order to continue operating a drinking water installation.
An ideal means of ensuring the sterility of drinking water is to use chlorine dioxide as a disinfectant.
Chlorine dioxide is highly effective against all types of germs and has a long dwell time in the tubing system, which means it disinfects even without re-dosing.
The big advantage of chlorine dioxide over other disinfectants is its effectiveness against biofilms.
It destroys the existing biofilm, thus removing the breeding ground for microorganisms, and prevents it from building up again.
Ideal application areas for Oxiperm include combating germs and pathogens, such as legionella in building installations, disinfecting cooling water systems, and disinfecting drinking water in water plants or industrial processes.
Chlorine dioxide is often used in the food and beverage industry for disinfection of process water or for CIP and bott le washing because it doesn’t change the taste or smell of the treated water.

 

Oxiperm OCC-164 uses concentrated 33 % HCl solution and 24.5 % NaClO2 solution to generate 4 to 10 kg/h of chlorine dioxide.

Reliable preparation and dosing of chlorine dioxide from dilutedsolutions for water disinfection
 

Oxiperm® Pro systems produce chlorine dioxide using diluted solutions of sodium chlorite (NaClO2 7.5 %) and hydrochloric acid (HCl 9 %).
They are available in four capacity levels, producing 5, 10, 30 and 60 g/h of chlorine dioxide respectively.
This capacity is sufficient to treat up to 150 m3 of drinking water per hour at a maximum concentration of 0.4 mg/l ClO2.
Chlorine dioxide is produced on demand from diluted solutions using the reliable sodium chlorite / hydrochloric acid, in accordance with the German Drinking Water Directive.
The chlorine dioxide solution produced is stored in an integrated or external batch tank and is added to the drinking water pipe as required using the integrated dosing pump or an external dosing pump.
