The McLean Engineering Product Line Overview

A wide variety of water problems occur within the United States. Those problems are predominantly determined by where you live.McLean Engineering, Inc. specializes in treating all problems found in Virginia. We have a wide variety of equipment to treat those problems.Based on every home’s unique situation, we will recommend a system or combination of systems that will most effectively treat your problem. A detailed explanation of the systems we sell – and the problems they treat – is offered below.Should you wish to learn more about any one of the systems, please feel free to contact us.

Well Pellet Chlorinator

• Removes odor and kills bacteria

• Also used when there are large amounts of iron in the water as a complement to the iron unit – not instead of

• Helps keep pipes clean by holding down iron build-up between the pump and filter

Chlorine Feed System

• Removes odor,kills bacteria and is used instead of the Well Pellet System

• Often used if the customer has a shallow well

Pot Ash Feed System

• Balances pH levels to between 7.0-7.5

• Used when there may be health issues in a home that require reduced sodium

• No filtration

• This system does not have sodium

Soda Ash Feed System

• Balances pH levels to between 7.0-7.5

• Does not increase the hardness of the water

• No filtration

Charcoal Filter

• Charcoal is the media that may be placed in either the traditional iron unit or acid unit

• Removes odor and chlorine

• Can also be used to remove petroleum products

Sand Filters

• Acid Correction System: Used when there is a small amount of sand present

• In-Line Cartridge Filter: Small sediment filter that needs to be changed by the customer on a regular basis

• Galvanized Tank: Tank used to filter sand out of the water supply when the sediment amount is higher.Recommended placement in front of the pressure tank in the water flow

• Sand Separator: Used most often when the available space is limited

Birm

• Media used to treat stubborn iron in traditional “iron units.”Typically, the media used to treat iron is calcium carbonate.If calcium carbonate cannot correct the problem, we can change the media to birm

• Birm units are iron tanks that incorporate both Limestone Calcium and Birm (each job is unique and media ratios may vary depending on water contamination)

Iron Removal System

• Removes most odors (sulfur, etc.)

• Removes iron from the water supply including both ferric and ferrous

• Filters sediment down to 5 microns

• Helps correct the pH

• Helps eliminate any brown/yellow/red staining

• Can convert the Iron Removal System to a Birm Unit and change the media mix to add Birm for more stubborn iron problems

Acid Correction System
(also referred to as a Neutralizer)

• Corrects the acidity of the water (pH below 7.0)

• Filters sediment (sand, particles, etc.) down to 5 microns

• Helps remove any blue staining due to the corrosion of copper piping

Water Softener

• Removes hardness from the water

• Can help eliminate iron to compliment an Iron Removal System

• Reduces manganese

• Removes copper from water caused by pipe corrosion

• Different resins can be added to a softener to treat some issues
such as tannin resin, etc.

R/O (Reverse Osmosis)

• Removes organic color bodies from the water

• Primary purpose of the R/O system is to remove 90-95% of the dissolved solids (or salts) in a stream of water

• Removes lead, nitrates, some petroleums

• Only equipment that will remove salt from the water source

U/V Light (Ultra-Violet)

• Ultraviolet light kills all bacteria and viruses

• Requires no materials or media components other than a replaceable light-bulb to be changed annually
