Ltd. This is always guaranteed in the case of original
spare parts. Only appoint trained or instructed
personnel. Clearly specify the responsibilities of the
personnel for operating, servicing and repairing the
system.
1.8 Instruction & Training Course
Assistance
As a contractor/operator you are obligated to inform
and/or instruct the operating personnel about existing
provisions of law and accident prevention regulations, as
well as existing safety regulations at the plant. In doing
so, the different technical qualifications must be
considered. The operating personnel must have
understood the training and it must be ensured that the
training is adhered to.
Only in this way can you ensure that your personnel work
in a safety conscious and risk aware manner. This should
be controlled on a regular basis. As the
contractor/operator you should therefore obtain
confirmation of each of the employee’s attendance in
writing.
On the following pages, you will find examples of the

4 Product Description
4.1 Intended Use
The Easyzon D on-site chlorine dioxide generation
system is intended for the following purpose: Automatic
generation of a <0.2% diluted chlorine dioxide solution
using sodium chlorite, hydrochloric acid and cool water.
The resulting solution can be used as a disinfection
agent for a wide range of applications.
4.2 Design and Function
The Easyzon D is a fully automated batch skid
system, with the output ranging from 100 to 500g/hr
of ClO2. The system can be configured with a
standalone reaction vessel to produce 100g/hr, or two
vessels in series to produce 200g/hr. Higher
concentration precursors can be used to gain 250g/hr
and 500g/hr respectively.
The system uses a plastic cabinet to mount its
instrumentation and house its reaction vessel/’s, these
are protected by a cover which can be secured shut
by a padlock on a toggle latch.
Chemical precursors are safely drawn into the reaction
vessel/’s [19]at a 1:1 ratio from a drum/tank by the
means of a vacuum created by a venturi [12]. Each
reactant is precisely measured and controlled via
individual flowmeters [6 & 7] and solenoid valves[8 &
9], which allow the reaction toproduce a ≈2 wt% ClO2
solution (Or ≈5 wt% ClO2with higher strength
precursors) . A predefined cycle time enables the
system to batch the necessary number of times to
generate the desired g/hr. After a reaction time of 15
minutes the product enters a level-controlled product
tank [17]. Any excess gas created in the reaction
process passes through the carbon filter [21] and into
the atmosphere. This process continues until the ‘Tank
Full’ level is reached, where the system waits for an
adjustable set time before restarting generation (see
section 8.5.3).
