Method for avoiding calcium carbonate deposits in drainage systems involves adjustment of drainage pipeline, manhole and connection-pipe at infiltration well or discharge water level and changing carbon dioxide equilibrium by ventilation

摘要

Method involves adjustment of drainage pipeline (1), manhole (2) and connection-pipe at infiltration well or discharge water level (3) at equal or above standard level. The water in manhole is collected and supplied into a lamella insert (4). The carbon dioxide equilibrium is changed by ventilation and the calcium carbonate targeted at the lamellas is separated. An independent claim is included for the system for avoiding calcium carbonate deposits in drainage systems.
