A.T Covers s.r.l. has twenty-five years of experience in the design, production and installation of aluminum covers for municipal and industrial wastewater treatment plants.
The odor control activity is increasing in Italy and in all the world, it comes as a result of the urban expansion which in many cases reaches the suburban areas of the cities where sewage plants are installed.
The quality of the materials we use guarantees practically an eternal duration of the aluminum alloy covers.
All the covers manufactured by AT Covers are designed according to the customer's needs with the utmost respect for safety regulations.
For over 25 years we have been designing and manufacturing aluminum alloy covers for civil and industrial waste water treatment plants.
Our reference list
The production control in A.T Covers meets all the requirements of the ISO 9001:2008 and EN 1090-1:2009/A1:2011 standards.
All the materials used are in aluminum alloy and stainless steel totally made with prefabricated elements. The advantages of our covers compared to other materials on the market are the following:
Our experience in the sector allows us to identify the problems
and suggest the appropriate solutions to the shape and type of existing tank in the different treatment phases.
where the inlet waste water is moved from the Archimedes screws generating odors.
feed channels, grit removal and in general all the primary treatments where the floating materials and solids contribute to create the bad odors.
with stagnation of sewage and sludge that are not yet biologically treated, and therefore generates bad odors.
for the biological treatment and the removal of nitrogen and nitrates that generate bad smells.
of the inlet sewage water or leachate, which accumulates the polluted water before the biological treatments.
where the sludge is accumulated before the digestion or the dewatering treatments. Here the odor production is concentrated.
where the sludge still have a high content of organic materials, and therefore produces a lot of odors.
that contain raw water that has not yet been biologically treated and that can be a source of bad odors.
In particular cases and depending on the location of the treatment plants, aluminum covers have been made to contain odors in the phases of:
• Oxidation, nitrification and denitrification
• Final sedimentation and drainage channels for treated water
• Final disinfection tanks
We have been designing and manufacturing aluminum alloy covers for odor containment in wastewater treatment plants since more than 25 years. Our engineers think each project based on every customer's needs.
