Virtually all manufacturers use the statements ‘low electricity consumption’, ‘economical’ in their advertisements. The difference is that the devices we know work in one mode and do not estimate inflow, i.e., whether there is a lot of sewage, or you on holiday for the week and there is no sewage, the wastewater treatment tank operates in the same mode at all times. Our wastewater treatment plant is on vacation with you i.e., if it detects that there is no inflow, it automatically enters the economy ‘holiday’ mode, which only maintains the functionality of the device until the inflow occurs. This feature further reduces energy consumption.
