Sewage treatment plants for municipalities

Despite the undoubted development of the sewage network, there remains a lot to be done. There are still municipalities with 0% sewage systems in our country. Apart from the agglomeration areas, we still have over 50% of areas with unregulated sewage management. In these circumstances, sewage treatment plants for municipalities are becoming more and more popular.

An optimally designed wastewater treatment system in the area of entire communes should first take into account the density of buildings, the amount of generated wastewater, the topography as well as the possibility of discharging the treated wastewater into the environment.

Before embarking on the project, a concept should be prepared, and plans of the system should start from areas with a compact development. Ideally, if treated sewage can be discharged by gravity into water courses, the network is uncomplicated, easy and cheap to operate. Another aspect is the technology. The solution should be adapted to local conditions in terms of the necessary area, environmental impact (noise, odors), as well as the requirements of the operator.

RotoSET BIG wastewater treatment plants that operate in the technology of rotating biological contactors are a dedicated solution for municipalities. First of all, they are easy and cheap, and have no adverse impact on the environment. Biological processes take place on rotating biological contactors powered by highly efficient geared motors with low electricity demand. The advantage of this solution is the possibility of expansion by adding additional bioreactors. This is especially important when extending the network over a long period of time. It is also noteworthy that foolproof operation requires no specialist knowledge in the field of technology.

Mixed-use areas allow for installation of the so-called local sewage treatment plants, which have integrated primary and secondary settling tanks, thereby the installation area is reduced to a minimum. The technology of rotating biological contactors guarantees exceptionally low operating costs, easy operation and no negative impact on the environment. These solutions also allow for expanding the treatment plant with additional bioreactors.

Where the buildings are dispersed, large distances between buildings and/or the terrain shape would result in investing in considerable numbers of pumping stations. The best solution may be to invest in domestic sewage treatment plants. The device should be selected depending on the size of the plot, soil and water conditions, the hollow of the sewage drainage pipe from the building and individual requirements. We recommend the use of possibly uncomplicated, easy and inexpensive rotary technologies or sprinkling biological contactors. Such contactors are housed in monolithic tanks, require no addition of bacteria during operation, and have a low demand for electricity. The treated sewage can be discharged both to watercourses and to the ground.
