摘要
The invention relates to a process for slurry discharge from the settling tanks for raw water processing, in order to obtain high quality potable water. According to the invention, the process is based on the principle of ultrasonic hydrolocation, using ultrasonic probes capable of continuously measuring the thickness of the slurry bed deposited in the vertical plane within a slurry tank, the information being then displayed on an LCD apparatus placed within a probe controller, the said controller determining the slurry deposition profile, the height of the slurry bed and its compaction degree and allows the process of mechanized valves closing and opening to be automatically controlled depending on the height of the slurry bed inside the settling tank, where, upon reaching the maximal set value for the respective height of the slurry bed, some valves for the discharge of the deposited slurry are opened depending on the water silt charge and irrespective of the time, said valves being then closed when the minimal set value is reached.
