At Purecowater, we specialize in tackling complex solid and liquid filtration problems by partnering with top-tier manufacturers. Among our premier offerings are the industrial and commercial water treatment solutions from Marlo, Inc. Known for their robust engineering and custom capabilities, Marlo systems are a staple in industries requiring high-quality water softening and filtration.
This guide breaks down the Marlo product lines we distribute, specifically focusing on their Industrial Water Softeners, Carbon Filters, and Multi-Media Filtration (MMF) systems. These systems are designed to protect downstream equipment, improve process efficiency, and ensure regulatory compliance.
Marlo Industrial Water Softener Systems
Hard water scaling is a primary cause of inefficiency in boilers, cooling towers, and heat exchangers. Marlo commercial and industrial water softeners effectively remove calcium and magnesium hardness, preventing scale buildup and extending equipment life.
MR Series: The Industrial Standard
The MR Series is the workhorse for most large commercial and industrial applications. These systems are built with epoxy-lined carbon steel pressure vessels and are capable of handling significant flow rates.
- Capacity: 150,000 to 1,050,000 grains per tank
- Flow Rates: 20 to 190 GPM (Continuous)
- Construction: Epoxy-lined carbon steel tanks (Non-ASME standard, ASME available)
- Control: Electromechanical or PLC options available
MHC Series: High-Capacity Solutions
For large-scale industrial plants requiring massive throughput, the MHC Series offers superior capacity. These units utilize extensive face-piping assemblies and larger resin volumes to meet high demand.
- Capacity: 1,200,000 to 5,400,000 grains per tank
- Flow Rates: 100 to 1,150 GPM
- Valves: Diaphragm or butterfly service control valves for 6″ piping and larger
Comparison of Marlo Softener Series
Choosing the right series depends on your daily water usage and peak flow rate requirements. Below is a quick comparison of the key industrial series.
| Series | Tank Material | Flow Rate Range | Ideal Application |
|---|---|---|---|
| MR Series | Carbon Steel | 20 – 190 GPM | Manufacturing, Large Commercial, Boiler Feed |
| MHC Series | Carbon Steel | 100 – 1,150 GPM | Heavy Industry, Municipal, Large Cooling Towers |
| MRG Series | FRP (Fiberglass) | Varies | Corrosive Environments, Salt Water Applications |
| MGT Series | FRP | 1 – 215 GPM | Light Commercial, Hotels, Apartments |
Marlo Media Filtration Systems
Marlo’s MFG Series covers a wide range of filtration needs, from removing suspended solids to neutralizing acidic water. These systems utilize the same robust tank construction as the softeners but are engineered with specialized internal distribution systems for backwashing granular media.
Available Media Configurations
The MFG Series can be customized with different media beds depending on the specific contaminants present in your water source.
1. Multimedia Filters (‘MID’)
These units function as high-efficiency depth filters. They utilize a layered bed of anthracite, silica sand, and garnet. This stratification allows for the removal of particles down to 5–10 microns. They are an excellent choice for pre-treatment for Reverse Osmosis (RO) units.
2. Activated Carbon Filters (‘ACA’)
Designed for the reduction of taste, odor, and dissolved organic material. The most critical industrial application for ‘ACA’ filters is the removal of free chlorine, which can irreversibly damage RO membranes and other sensitive downstream equipment.
3. Iron Removal Filters (‘MGA’)
Using Manganese Greensand media, these filters oxidize and precipitate soluble iron, manganese, and hydrogen sulfide. They are essential for treating well water to prevent staining and fouling.
4. Filter-Ag® Filters (‘AGA’)
These use a non-hydrous silicon dioxide media with a fractured surface area. They feature low pressure drop and are effective for high-turbidity applications, removing solids in the 20–40 micron range.
Controller and Valve Options
Marlo systems are not “one size fits all.” Purecowater can configure these units with various control packages to suit your operational needs:
- MX-III Controller: Electronic programmable logic for complex cycling and multi-tank coordination.
- PLC Packages: Allen-Bradley or Siemens PLCs for full integration into plant SCADA systems.
- Skid Mounting: Systems can be pre-piped, pre-wired, and skid-mounted to reduce on-site installation time and costs.
Who Should Use Marlo Systems?
Marlo products are engineered for durability and high volume. They are best suited for:
- Manufacturing Plants: For boiler feed water and process rinsing.
- Power Generation: Cooling tower filtration and makeup water treatment.
- Institutions: Hospitals, universities, and large commercial laundries.
- Municipalities: Drinking water treatment and iron removal.
Whether you need a simple twin-alternating softener or a complex, skid-mounted multi-media filtration package, Purecowater works directly with Marlo to deliver the exact specification your facility requires.
