Modular multi-filter systems and methods of use

A multi-filter modular pack assembly for filtering fluid from an aquatic application, comprising:

• a vessel including a plurality of filtration modules;
• an inlet conduit designed to direct an untreated fluid or a pre-filtered fluid from the aquatic application to the plurality of filtration modules;
• an outlet conduit designed to direct a filtered fluid from the multi-filter modular pack assembly to the aquatic application;
• a chemical cleaning system including a chemical cleaning tank designed to retain a chemical cleaning agent, wherein the chemical cleaning system is in fluid communication with the vessel;
• and
• a controller designed to:
• determine whether one or more of the plurality of filtration modules is fouled based on a determined permeability value;
• and
• initiate a cleaning procedure when the determined permeability value is below a permeability threshold value.

A method for cleaning a multi-filter modular pack assembly comprising:

• receiving an untreated or pre-filtered fluid from an aquatic application into a multi-filter modular pack assembly;
• directing the untreated or pre-filtered fluid into one or more of a plurality of filtration modules;
• determining a pressure differential between an inlet of the multi-filter modular pack assembly and an outlet of the multi-filter modular pack assembly;
• determining whether the pressure differential exceeds a predetermined pressure differential threshold value;
• and
• initiating a cleaning procedure when the pressure differential exceeds a predetermined pressure differential threshold value.
