I.T.D. 21 sa, created in 1999 and based in
Luxembourg, is a SME supplier of water treatment equipments and environmental
technologies. I.T.D. 21
stands for professional water treatment laying utmost emphasis on hygienic securing
of water of any kind be it drinking water, industrial water in drinking water
quality, swimming-pool water, industrial water, product or gray water as well
as sewage water and environmental friendly solutions.
For the sake ofconvenience, human been has always sought to ensure sufficient quantity and
quality. Often these two concerns induce managers to take preventive measures.
Large water users are :
Concern 2 : qualitative aspects
Throughout the distribution chain, the water quality may degrade at different levels as:
Stagnant water, ground water or infiltrated water sources by sewage
The decay and water cuts pipelines and feeding networks
Biofilm formation generating bacterial colonies like legionella in distribution channel of public institutions and
Among the many microorganisms conveyed by water, we can cite viruses, bacterias, parasites and protozoa; when the quantity of
these exceeds a threshold set by WHO,
they become pathogenic and therefore pollutants capable of generating
For this reason we present advantageous solutions for
water treatment and water management allowing acting in a safety-oriented
way through sustainable product solutions, management and servicing.
In this line the central objectives are:
For ex. the EC disinfection system generates a disinfectant ensuring risk-free
water treatment, distribution, storage and transport. The disinfectant can be
adjusted according to requirements and/or preferences. This process conformable with chlorination is
certified by DIN as well as by the UN and WHO and is in compliance with all
current national and international regulations as to water treatment. The EC performs without any
additives with low energy demand, making possible a safe and environmental
This very sustainable system performs with stability for long time, has
an extremely low maintenance and is simple to use. It guarantees no recontamination
of water up to several days. The additional variant of solar powered process with optional use of
conventional battery systems as off-grid operation makes this technology very
beneficial for rural and isolated locations.
The main disinfectant species generated by the EC are hypochlorous acid
and several oxygen based compounds.
The EC system treatment is able to put right
this type of degradation of water quality.
