Iron Removal Filtration System

The presence of ferrous, ferric, bacterial and organic iron in groundwater can pose significant design, operational and cost implications to remediation and water treatment processes. Newterra Iron Removal Systems (IRS) provide an effective, cost-efficient approach to removing iron from water. The iron removal treatment uses multiple technologies based on intensive aeration/degasification followed by filtration.

Product Overview

Capable of handling iron concentrations from 5 to 50 ppm (on a non-reagent basis), the Newterra Iron Removal System also helps reduce other pollutants, including hydrogen sulfide, carbon dioxide, methane, radon, manganese, and organic substances. The core of the system is special polymer floating media that effectively filter the water but does not require regeneration or replacement. The system first oxidizes the ferrous (dissolved) iron, which allows the removal of all four types of iron to levels below 0.3 ppm. Backflush containing the concentrated iron is chemically treated and run through an automatic particulate filter.
In addition to our advanced technology-based system, Newterra offers other concentrating solutions approaches for iron removal from water: Green Sand Filtering and Backwash Systems for applications under 4 ppm and chemical treatment and clarification or membrane treatment above 50 ppm. These approaches also involve a filtration process with backwashing capabilities that produce a low volume of water with higher iron concentrations than the full process stream. The backwash water is typically sent to a holding tank and treated with flocculation and coagulation agents for efficient iron removal.


  • To remove iron, manganese, hydrogen sulfide and/or certain metals
  • Iron quickly falls out of the solution and sticks to surfaces, causing scaling and fouling
  • Iron can plug filters, plumbing and foul reverse osmosis (RO) membranes
  • Iron will foul boiler tubes inhibiting heat transfer
  • Hydrogen sulfide has an objectionable odor and is highly corrosive
  • Metals can cause fouling on plumbing and RO membranes


  • Frame: Painted carbon steel or stainless steel
  • Membranes: Thin film composite
  • Membrane Housings: fiver-reinforced polymer (FRP)
  • Controls: Customized for the end user
  • Piping: Polyvinyl (PVC), Duplex stainless steel (SS) or Super Deplex SS
  • Instrumentation: Customized for the end user
  • Cleaning System: Integral to the skid


  • Provides effective iron removal with little or no chemicals
  • Certain media can also remove manganese, hydrogen sulfide and some metals
  • Inlet/outlet pressure gauges
  • Efficient internal designs
  • Self-adjusting backwash flow control
  • Safety air release valve for pressure fluctuations
  • Minimum energy and maintenance requirements
  • Stand-alone tanks or modular skid-mounted (pre-piped & pre-wired) options
  • Clear backwash drain line for visual inspection (PVC plumbing only)
  • Steam subitizable tank options (steel vessel only)
