Hybrid filter and chemical cleaning assembly and method

A method of cleaning a filtration module of a hybrid filter assembly designed to process water from a pool or a spa, the method comprising:

• providing a chemical cleaning system;
• providing a valve in fluid communication with the chemical cleaning system and the filtration module;
• and
• providing a controller in communication with the chemical cleaning system, the controller:
• determining a backwash parameter value of a membrane of the filtration module at a first time period;
• and
• initiating a chemical cleaning procedure whereby the controller actuates the valve to provide a chemical agent to the membrane of the filtration module.

A method of operating a filtration system, the method comprising:

• providing a hybrid filter assembly including a first filtration stage and a second filtration stage, the second filtration stage including a filtration module;
• processing water from a pool or spa in the first filtration stage to generate a prefiltered water;
• providing the prefiltered water to the second filtration stage whereby the second filtration stage generates a filtered water;
• providing a controller;
• initiating a backwash mode;
• initiating a chemical cleaning mode;
• and
• initiating a bypass mode.
