Ozone Technologies
has been operating since 1990 and has developed and designed,
manufactured and supplied ozone generating systems from 0.25 grams
per hour to 200 kilograms per hour.
Our offices are located in Napier, New Zealand with full manufacturing
facilities and laboratory on site. Located only five kilometres
from Hawke’s Bay Airport, we are ideally situated for
client access to our services. In addition, consultation and
system requirements are often carried out on our clients premises
- for your convenience we can come to you. This hands on approach
allows greater understanding of physical requirements and enables
our process engineer to tailor a process for every clients specific
needs.
Ozone Technologies has the experience and technical ability
to assist in all aspects of the plant and process design based
on customer specific requirements. Additionally we provide long
term ongoing advice, maintenance and services for all of our
installations. Our state of the art digitally controlled IGBT
technology with its efficient high voltage power supply (PSU)
is second to none and will provide long term reliability with
low installation and operating costs.

active resolution...
In addition to our experience within the industry, our greatest
strength lies in our ability to address client's needs from conception
through to completion of the project and beyond. This is quite different
from the "equipment vendor" approach of many competitors.
While Ozone Technologies is an OEM (Original Equipment Manufacturer),
we consider process solutions our primary function.
Implementation of a maintenance program after plant commissioning
provides ongoing support and security to our clients and maintains
good working relationships with them. We advise on improvements
and optimization of processes involving ozone plant and equipment.
References and contact details can be provided if required.
development of process...
We are involved with universities and private institutions regarding
the development of new technology processes in pharmaceutical, aquaculture,
horticulture and small skid mounted water disinfection systems up
to 1000 m3/day.
We have developed revolutionary ozone CT control systems for applying
correct ozone doses to meet NZDW standards. This system enables
on line monitoring of CT, temperature, pH and takes into account
the hydraulic dynamics of the reaction chambers. All parameters
are electronically controlled and recorded, and time and dated stamped.
This control system has proven invaluable in the opening field of
gas phase ozonation for horticultural applications. Currently development
is underway for monitoring systems to partner this technology.
We can advise on methods of ozone contacting, design of reaction
tanks and also supply laboratory ozonation equipment for trials,
either on site or in our premises. We have our own laboratory and
chemist available to carry out trials to establish the correct parameters
for your situation should this be required.
about the ozone plant...
Our plant provides the following unique advantages and features:
progressive technology...
Developed Processes:
Patented ozonation treatment in tanneries for removal of sulphides
(260752).
Ozone Technologies have developed a revolutionary process for 'cow
water' treatment for the dairy industry. This copyrighted process
utilises ozone as a micro-flocculant and also for disinfection enabling
this wastewater to be reused as process water. We anticipate this
process to be installed throughout the Dairy Industry in Australasia
over the next few years.
Horticultural Developments:
There is a continuing search worldwide for sustainable and safe
alternatives to the currently used hazardous and sometimes environmentally
unfriendly materials for the control of harmful bacteria, fungi
and insects in greenhouse crops. Low dose ozone, recently approved
by United States Food and Drug Administration as a post-harvest
fungicide treatment, could be a candidate sustainable and safe pesticide
in both conventional and organic production. Ozone has a short half-life
and rapidly breaks down to oxygen, leaving no chemical residue.
Studies on the efficacy of low dose ozone on pathogens and harmful
insects such as whitefly, its effect on crop growth and quality
and its effect of beneficial organisms in a protected cropping system
are only in their infancy. Much of the research has been done in
laboratory conditions, with no real reflection on commercial growing
practices. We seek to determine correct dosage, concentration, time
and ramp rates (a still higher concentration of ozone for a few
minutes) to be of real benefit to the grower, without causing plant
damage.
Gas Phase Ozonation for Sanitation in Greenhouses:
A survey undertaken recently for Vegfed’s Fresh Tomato Sector
of a number of greenhouse tomato growers about their methods of
crop protection in 2004 and changes in pest control over the past
15 years has again identified whitefly as the number one problem
facing growers. Russet mite and thrips are also pests of concern
to most greenhouse vegetable growers.
This past year has seen the completion of trials using gas phase
ozone to reduce fungal, bacterial and insect damage in greenhouses.
Our trial partners are T.Ivecevich (of Vegfed), BOC Gases, UNITEC
and Aeroqual.
.A pilot study conducted at Unitec in 2002 showed that low ozone
concentrations applied at night significantly reduced greenhouse
fungal and bacterial populations. Another by Unitec staff in 2004
has shown that low ozone concentrations applied at night had no
adverse effects on crop growth in a commercial greenhouse. There
were early indications that when plants were infested by whitefly,
sooty mould did not form on the resultant honeydew. This will be
investigated further in 2005.
Gas Phase Ozonation for CA and Coolstorage Facility:
Trials for gas phase ozone to control ethylene production in a postharvest
packhouse are well underway. These tests are being conducted in
several identical rooms with different application rates and exposure
times. All monitoring is being datalogged back to a central server
to provide a record (and recipe writer) for the system.
We are priviledged to be part of this very forward thinking series
of trials. The instigators have invaluable knowledge of their industry,
and have made their staff and laboratory available to conduct exacting
measurements of each step. So far the results are proving very positive.
Along with the primary goal of ethylene reduction in the storage
facility we are seeing a marked drop-off in plant pathogens and
fungal damaged fruit, resulting in a better packout.
While it will be some time before accurate parameters can be known,
this work is set to provide nothing but benefits and longer shelflife
for many applications in the postharvest horticultural industry.
other services and related areas...
Ozone Technologies offer a range of services that are not directly
related to ozone treatment. We are suppliers of oxygen generators
and monitoring equipment for various applications also.
Our engineers can offer expert servicing of Thomas oxygen compressors
for medical applications in our workshop. Currently we service the
HBDHB, talk to us if you require a service agent for your medical
compressors. In addition, we have an excimer laser technician in
our team.
Ozone Technologies source and supply monitoring and test equipment
such as spectrophotometers, dissolved oxygen monitors, test kits
for various water treatment applications (for example, chlorine,
ammonia, ozone, pH), ORP meters, and are able to provide a range
of reagents and spares to support this equipment.
We are also suppliers of ozone monitors for both gas and aqueous
phase monitoring.
