This invention provides an integrated device for controlling
microbial contamination in
seawater desalination, comprising a base, a high-pressure pump mounted on the left side of the base, an online flow cytometer
system mounted on the base, and an RO membrane holder mounted on the right side of the base. The base facilitates the installation of the dosing mechanism,
diaphragm pump, and online flow cytometer
system. The high-pressure pump pressurizes and delivers
seawater for subsequent
desalination via the RO membrane. The online flow cytometer
system monitors the microorganisms in the
seawater delivered by the high-pressure pump and simultaneously controls the
diaphragm pump to deliver the bactericide from the dosing mechanism upstream of the
cartridge filter, sterilizing the seawater entering the RO membrane and thus extending the cleaning cycle and lifespan of the RO membrane.
