AT Covers Aluminum covers

for odors containment in wastewater treatment plants

OUR COMPANY CONTACTS

We design customized covers

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.

Screw pumps

Screw pumps

where the inlet waste water is moved from the Archimedes screws generating odors.

Channels

Channels

feed channels, grit removal and in general all the primary treatments where the floating materials and solids contribute to create the bad odors.

Primary sedimentation treatments

Primary sedimentation treatments

with stagnation of sewage and sludge that are not yet biologically treated, and therefore generates bad odors.

Ossidazione

Oxidation tanks

for the biological treatment and the removal of nitrogen and nitrates that generate bad smells.

Equalization tanks

Equalization tanks

of the inlet sewage water or leachate, which accumulates the polluted water before the biological treatments.

Vasche di ispessimento

Sludge Thickenners

where the sludge is accumulated before the digestion or the dewatering treatments. Here the odor production is concentrated.

Aerobic sludge digester tanks

Aerobic sludge digester tanks

where the sludge still have a high content of organic materials, and therefore produces a lot of odors.

Sand traps

Degritting tanks

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
