Title:
COOLING TOWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/159299
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 pump 10 starts operation once the electrical conductivity reaches an intermediate value C1. The water supply from the pump 10 undergoes RO treatment by an RO device 13, concentrate is discharged outside the system, and permeate is introduced to the pit 1d. As a result of the inflow of permeate, there is a slow rise in electrical conductivity of the water inside the pit 1d. The electrical conductivity continues to increase and reaches an upper limit of C2. Once that happens, a forced replenishment water valve 22 opens and the replenishment water inside a replenishment water tank 15 is supplied to inside the pit 1d via pipes 19, 20.
