"At healthcare facilities, there is a strong demand for a new advanced air cleaning technology to prevent infectious diseases such as severe acute respiratory syndrome (SARS) and Hospital Acquired Infections (HAI). The system would avoid the high costs related to healthcare and legal matters which increase every year and are a burden to the fixed costs of maintaining sanitary systems in Europe and USA. The integrated machine is intended for the air purification of hospitals, surgery rooms, ICU’s, isolation rooms, laboratories, drug manufacturing units, and storage facilities. Also, the air sterilizing device from the project would be applied in the construction and renovation activities that occur in or around healthcare facilities. The project is directed to a design of a new method and device for purification of indoor pollutants (VOCs - volatile organix compounds, microbes, spores, and fungi). The purification unit will be able to sterilize airborne biological agents contained in a moving air stream at high airflow rates. The device will also include a first pre-treatment purification unit capable of retaining and destroying Particulate Matters contained in the air prior to the sterilizing unit. The idea is to design a stage prior to the plasma filter using combined electrostatic precipitators (ESP) which are internally coated with a photocatalytic compound in order to kill the precipitated microorganisms. In this device, a combination of different effects such an ionizing atmosphere, ozone and biocide elements will destroy the microorganisms with about 99.9% efficiency. After this ESP filter, a new ozone filter system will be placed in order to prevent the presence of ozone that was generated in the ESP system."
