A clean water supply is the single most important determinant of public health. We have extensive experience of water development projects throughout the world, providing specialist technical assistance at all stages of the project cycle.
Roughton adopts the sewage treatment method most appropriate to the environmental and budgetary constraints of each project. The following are some typical approaches taken:
Settlement
Various settlement tank designs are adopted as appropriate based on horizontal flow, radial flow or upward flow as appropriate with sludge withdrawn under hydrostatic head.
Biological Treatment
For relatively small communities treatment in reed beds is a very efficient and environmentally friendly treatment process.
Sludge Disposal
Today sludge is considered as a resource enabling the generation of power and the production of fertiliser.
Stabilisation Ponds
In hot climates the technology of symbiotic action of algae and bacteria used in waste stabilisation ponds is often more appropriate for treating sewage. Our designers ensure designs are simple and operational requirements minimal.
Package Plants
Various technologies have been adapted in the development of prefabricated sewage treatment plants.
