This is a more complex filter that can be applied to the river. In this filter, the water passes through a settling cone that collects debris, it is designed with an up flow design and passes through other media that helps improve the filter's performance. At the final stage, the water is polished and can be implemented into a city's water system. In addition to this, the city has more clean and accessible water, this can help reduce the amount of water shortages that happen in the city.
