The MARLO ‘MHC’ Series is designed for large industrial water softening applications. Individual tank capacity ranges from 1,200,000 grain to 5,400,000 grain with continuous flow rates of 100-1,150 GPM. Single tank, multi-tank parallel, twin alternating, and triple alternating systems are available with a wide variety of timer and water meter controllers.

Features

• Epoxy lined and prime exterior finished carbon steel pressure vessels. Non-ASME construction with 100 psig working pressure.
• High capacity, sulfonated polystyrene cation exchange resin in sodium-form.
• Galvanized steel face-piping assembly with cast iron, normally-open, “Y” pattern diaphragm control valves. Filters with service piping 6″ and larger utilize flanged carbon steel face-piping and double-acting butterfly service control valves.
• Pilot stager valve controller for automatic regeneration operation. Pre-wired in a NEMA-4X enclosure with an adjustable timeclock for regeneration initiation.
• Self-adjusting flow control to maintain accurate backwash rates.
• Pressure-compensated brine injector for correct brine flow and concentration.
• PVC media-retaining underdrain distribution system in either hub-radial or header-lateral configurations for minimal pressure drop and proper regeneration.
• Rigid, polyethylene or FRP brine tanks with wet-salt storage and water re-fill valves
