Title:
COOLING TOWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/159300
Kind Code:
A1
Abstract:
When recirculation and supply of cooling water from a cooling tower 1 to a heat exchanger 4 is continued, the water level inside a pit 1d gradually decreases and electrical conductivity gradually increases. A submersible pump 8 starts operation once the electrical conductivity reaches an intermediate value C2. The water supply from the submersible pump 8 undergoes RO treatment by an RO device 13, concentrate is discharged outside the system, and permeate is guided to the pit 1d. Once the water level decreases to a lower limit H0, a ball tap 21 opens, and replenishment water is supplied until the water level increases to an upper limit H1. The submersible pump 8 stops when the electrical conductivity decreases to a prescribed value C1 in conjunction with the replenishment water supply.
