Aluminium dome roofs for wastewater plants and seawage treatment |
In recent decades wastewater plants have been increasingly fitted with aluminium roof structures. For covering clarifiers, trickling filters, basins and many other vital parts of a sewage treatment plant an aluminium dome structure may be the perfect choice.
Being free-span,light weight and all aluminium structures installing an aluminium dome or structure will result in eliminating emissions and odours and will help sustaining a controlled process environment.
The structures will be custom designed to fit the structure involved. There will be no need to interrupt the operation of the installation during the construction of the cover. |
 |
| Dome features |
| - |
maintenance free, no need for any blasting or painting |
| - |
excellent vapour tightness, resulting in eliminating any hazardous or irritating emissions and odours |
| - |
keeps contaminants out from the treatment process |
| - |
moderates process temperatures |
| - |
fully compatible with all waste water effluents, including high sulphur containing vapour fractions |
| - |
light weight and clear-span structure manufactured from aluminium and stainless steel |
| - |
can be fitted on installations in service with minimum modifications. |
| - |
expected service life in excess of 40 years |
| - |
designed for each specific project, complying with local building codes |
| - |
easy and quick installation, full installation manuals and project support available |
| - |
successfully installed at many wastewater plants around the world |
| - |
can be designed for high wind- and snow loads |
| - |
esthetical solution in reducing irritating and hazardous odours |

Flat covers
Yet another advantage of a dome is its light weight. This means reduced foundation costs. But its weight belies in its strength. When applications require, Aluminium Domes can even be designed to support heavy processing equipment. From the blazing Mojave Desert to the humitidy of Singapore and the gale force winds and snow of the Antarctic, Aluminium Domes have repeatedly proven their strength, durability and flexibility. |

Aluminium, the material of choice
Waste water atmospheres can be very aggressive and corrosive for construction materials. From extensive research and experience we know that aluminium is an excellent material and will deal with these circumstances without generating any long term concerns on the integrity of the structure. Even high Sulphurous containing atmospheres will not deteriorate aluminium alloys as used for manufacturing covers for waste water facilities. This makes it the ideal material for covering open facilities in urban areas Combined with the fact that aluminium does not require any surface preparation or coating, this makes aluminium the technically and economically best solution |
Suspended covers
In certain applications the volume of the air to be treated could generate a concern. The lesser the volume to be treated, the lower the treatment costs. To facilitate this drive for low costs on air treatment we are able to offer suspended, or truss supported covers, both minimizing air volume to be treated. For general applications a waste water cover or dome will be engineered to deal with a slight internal under pressure generated by the air treatment flowing out. This under pressure will then ensure that waste water air volumes and the belonging remain within the atmosphere of the structure. |

Structure and appurtenances
Apart from aspects mentioned earlier our aluminium structures will be able to deal with existing structures like bridges, access areas, ducting and others. Engineering will revolve around a minimum in changes to the actual waste water plant and the way it is operated.
