KOALA SHW and KOALA OT Indoor air de-pollutors for facilities


D.A.TECH. srl (Depollution Air Technology) was founded by a multi-skilled team of specialists who decided to divulge the results of studies and research conducted on air pollution and its effects on the human body.

The most important result of the work carried out was the planning and realisation of a nanote- chnology, the Koala Technology Evolution (KTE), a worldwide innovation capable to remove indoor air pollution using nanofiltration systems. The systems are covered by international patent and act upon a diversity of pollutants according to physical conditions (solid, gaseous, microbiological and electric).For over 20 years D.A.TECH. srl has been investing its resources in studies and scientific research collaborating with Research Institutes, Universities and Foundations, at national and international levels, so as to perform instrumental and preliminary clinical tests aimed towards the evolution of specific technology for removing air pollution.The target is to guarantee optimal conditions of indoor air in both civil and professional environments and to ensure a greater well-being to those who frequently live or work in such environments.D.A.TECH. has been present on the market for over 10 years supplying its products to hospital and military sectors.
Equipment for air depollution provided by the innovative Koala Technology has been installed in some of the most important Italian hospitals, in operating theatres and in intensive care and sterile units.Koala Technology was selected by the Italian Navy as the quality standard for air within its subma- rines.The company obtained the NATO Code A 1795.D.A.TECH is CE certified : EN ISO 9001:2008.Following the use of the Koala Technology in the military field, the first contacts with the ASI ( Italian Space Agency) and with the Italian National Research Council began for the application of this new KTE nanotechnology within the space sector.

Hospital-acquired infection refers to the acquisition of an infectious disease, in a hospital, neither clinically present nor incubating at the time of admission, but generally occurring after 48 hours of admission, during the same hospital stay or discharge.

Studies and research carried out reveal that about half of hospital infections are caused by organic air pollution and the other half are transmitted by contact (cross-infection).

Mostly at risk of developing infections due to biological pollution are patients admitted to the intensive care unit (up to 30% of cases), in rehabilitation in oncology and Hematology in geriatric wards and, in general, in all those wards where immune suppressed patients are recovered. Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli resistant or refractory to broad-spectrum antibiotics, are responsible for about half of hospital infections. Approximately 45% of the rooms in every hospital are colonized by bacteria resistant to drugs and disinfectants.

The cost of hospital infections is very high and has an impact on the healthcare budget causing an increase in global annual costs amounting to approximately 10% of healthcare costs.

In light of the data recorded in recent years in all countries, including industrialized ones, there is a need to take action on infections due to indoor pollution generated in hospitals and public health facilities, through the biological remediation of such environments.

Indoor air pollution inside hospitals and generally in healthcare facilities is particularly worrying as it not only involves those who work there (doctors, nurses, …), patients and visitors, but also has negative consequences in terms of costs and availability of resources within the entire health care system.

Microorganisms are the primary source of indoor air contamination in healthcare settings. Exposure to bacteria, viruses, mold and fungal spores due to potential biological hazards.

Suspended bacteria and fungal species (bacteria: Staphylococcus aureus, E. faecalis, M. luteus, B. Substilis, B. cereus, Escherichia coli, Enterobacter erogenous etc.., and fungi: Aspergillu, Penicel- lium, Rhizopus, Alternaria …) are suspended in the indoor air in hospitals and are considered a potential source of hospital infections. The microbial influenza load in the indoor air in hospitals in- fluence the rate of hospital infection.

Aerosol infection tends to be extremely small (<0.1 um) and can remain suspended in the air and transported for long periods of time facilitating the transmittal of pathologies. Consequently the risk of infections in high-risk environments (hospitals and clinics) and, in general, in all confined spaces is extremely high.

The control and drastic reduction of the presence of microorganisms (bacteria, viruses, mold and fungal spores), which cause a large number of infections and discomfort play a fundamental role in the prevention of such infections.

Apart from biological pollution, other factors should be taken into account regarding indoor pol- lution present in healthcare environments such as human presence, the chemical disinfectants used to clean surfaces, textiles fibers of lab coats and particulate from latex gloves used by doctors, outside particulate, etc..

All these harmful substances act as carriers of bacteria and viruses, and remain dispersed in the atmosphere.

In the specific, in the operating theater during surgery, these deposit on the operating table and on the surfaces where surgical instruments are placed and on the body of the patient, who is in- evitably exposed to the risk of developing infections.
