Air purification
ATT & AT offers a different range of air purifiers and depending on the type of pollution, the appropriate purification technology is selected.
Chemical filling
adsorption of pollution from the air on the surface of an adsorbent made of a combination of activated carbon and alumina impregnated with different chemical agents such as sodium or potassium permanganate
Filters for sewer inspection shafts
preventing the spread of unpleasant odors from the ventilation openings of cast iron covers of public drainage, extracting H2S and ammonia
Tube passive filters
for installation in smaller biological devices, pre-pumping shafts, vents and facilities with an air filtration capacity of up to 25 m3/h (activated carbon and chemical filling), (biofilling) 15 m3/h.
Active filters
removal of unpleasant odors and corrosive gases from wastewater treatment plants
Photocatalytic air purification
People spend an average of about 90% of time indoors, and depending on age and activity level, a person inhales 10-20 m3 of air per day, so indoor air quality is extremely important.
Scrubbers (gas scrubber)
A scrubber or gas scrubber is a device that allows the collection of solid particles due to contact of contaminated gas with a suitable liquid.
Droplet separator
The droplet separator is used to separate the moisture droplets from the polluted air from the bright surfaces of the tub, what is separated in this device via a pipeline is handed over to the scrubbers in the form of a liquid.
Biofiltration
With the constant development of urbanization and industry, more and more industrial and utility plants are located in or directly in residential areas, which can have a negative impact on the quality of life of people in these areas.
Active carbon
With the constant development of urbanization and industry, more and more industrial and utility plants are located in or directly in residential areas, which can have a negative impact on the quality of life of people in these areas.
