We try to design our biological treatments to work as continuously as possible, because this is the most efficient way to operate. In any case, biological systems allow stops of hours, or even days, without any type of contraindication.
When we design biological treatment lines, for systems that operate discontinuously, we usually propose the construction of a buffer tank – which are filled with the contaminated raw water – and which allow constant recirculation to our treatment plant. This approach achieves maximum productivity of the biological and also a smaller plant design, since it is adapted to a low average flow rate, which minimizes the investment cost.
