A control system has a water purification module and a control module. The water purification module has a preliminary filter and a reverse osmosis filter. The control module regularly controls the purification and the drainage of the water purification module, and solves the problem that the TDS value of the water on both sides of the reverse osmosis membrane is too high after the water purifier is on standby for a period of time. The control system regularly drains high concentration water on both sides of the reverse osmosis membrane to improve water purification efficiency.

There is provided a retrofit control module that is connectable to various types of reverse osmosis systems, and a method of using the same. The retrofit control module includes a controller, the controller being located within a housing. The controller includes a first communication interface, the first communication interface being connectable to the reverse osmosis system, a processing unit and a memory connected to the processing unit. The processing unit is configured for receiving at least one parameter of the reverse osmosis system, comparing the at least one parameter of the reverse osmosis system with a predetermined threshold and in response to the at least one parameter of the reverse osmosis system being above the predetermined threshold: transmitting a control parameter to the reverse osmosis system, the control parameter causing the reverse osmosis system to control at least one component of the reverse osmosis system.
