Water Purification
Reverse Osmosis
Raw Water is forced into the membrane housing under pressure – as high as 800 PSI. The water is forced through the membrane and enters the center tube without most of it’s contaminants which are discharged to drain.
We offer Packaged Reverse Osmosis Systems :
- Small Scale
- Large Scale
- With Pretreatment Skid
Sand Filters, Carbon Filters,
Water Softeners & Greensand Filters
Sand Filters, Carbon Filters, Water Softeners and Greensand Filters are all tank based water treatment technologies.
DI – Deionization Systems
Deionization Systems or Ion Exchange Systems remove contaminants by exchanging them with another ion. In a softener it’s sodium that gets exchanged off the resin and or water constituents(H+ and OH-) in mixed resin exchanges.

EDI-Electrodionization Water Systems
Perhaps the most recent widely accepted Water Purification process is EDI – Electrodionization.
EDI removes the remaining dissolved minerals (TDS) after Reverse Osmosis. EDI takes the place of the Ion Exchange step in many Electrodeionization System Designs.

We utilize Electropure EDI systems manufactured by Snowpure.

Iron Removal Filters/Systems
In New England iron is our most difficult water contaminant.
Also in New England iron is our most common contaminant.
Well waters contain Iron.
City water contains Iron corrosion of city mains.
Cooling Water contains iron from corrosion of piping in the cooling water system.
For well waters it’s best to get the iron before it goes from dissolved to suspended.
Greensand Filters
Water Softeners
For suspended Iron in the incoming water to a facility we use:
Sand and Multi-Media Filters
Once the Iron is in a facility to treat the process water we use:
Bag Filters
Cartridge Filters
