EXPERT IRON FILTRATION SOLUTIONS
At Land & Water Technology, our team of skilled engineers has developed an innovative chemical-free bore water iron removal system. Located in Malaga, we understand the prevalence of iron as a common water contaminant in Western Australia. Removing iron can be challenging due to its ability to change valence states, transitioning from the water-soluble ferrous state (Fe2+) to the insoluble ferric state (Fe3+). This transition occurs when oxygen or an oxidizing agent is introduced, causing the ferrous state to precipitate into a rusty (red-brown) appearance in water and its surroundings. In deep well water pumped into distribution systems, the adsorption of oxygen triggers this change. It is crucial to remove ferric iron before it causes damage to valves, pipes, water treatment equipment, and water-using devices.
With over 20+ years of expertise in treating iron from bore water and preventing future iron-related issues, our team of bore water Iron Filtration experts is here to help. We recognize that bore water serves as a vital irrigation source for many farmers. However, it often contains high levels of iron and other minerals that can pose challenges for crops, equipment, and irrigation systems. Our dedicated experts are always available to guide you in selecting the most suitable iron removal system for your bore water. Additionally, we offer comprehensive installation and maintenance services to ensure your system operates at its peak performance, providing you with clean, iron-free water.
Experience the benefits of our specialized iron filtration systems in Perth and ensure the optimal growth and productivity of your crops while protecting your irrigation infrastructure. Contact us today for personalized assistance and reliable solutions tailored to your specific needs.

FILTRATION PROCESS
At Land & Water Technology, we are proud to offer an advanced iron filtration system that utilizes a combination of specialized media and air injection technology. Our system is specifically designed to effectively remove iron from water, providing you with clean and high-quality water for various applications.
- Air-Injection – To enhance the filtration process, our system incorporates air injection technology.
- Media-Bed – Our iron filtration system contains a specially formulated media bed that is designed to target and capture iron particles.
- Filtration & Removal – As the water passes through the media bed, the iron particles are adsorbed onto the media surface. The media’s unique properties facilitate the physical and chemical adsorption of iron.
- Backwashing – To maintain the system’s performance, periodic backwashing is initiated. During this process, water flows in the reverse direction through the media bed, dislodging trapped iron particles and flushing them out of the system.
- Rinse & Recharge – After backwashing, the system undergoes a rinse cycle to remove any remaining debris. This is followed by a recharge phase, where the media bed is replenished and prepared for the next filtration cycle.
FREQUENTLY ASKED QUESTIONS
What is iron filtration?
Iron filtration is a water treatment process designed to remove iron contaminants from water sources. It involves using specialized filtration systems and media to effectively capture and eliminate iron particles, resulting in clean and iron-free water.
How much does an iron filtration system cost?
The price of our iron filtration system depends on several factors including; application of the system, bore flow rate, iron levels, location of the system, maintenance frequency and more.

Why is iron filtration necessary?
Iron in water can cause various issues such as metallic taste, discoloration, staining on fixtures and laundry, and clogging in pipes and appliances. Iron filtration is necessary to eliminate these problems, improve water quality, and protect plumbing systems and water-using equipment.
How do I determine if I need an iron filtration system?
If you are experiencing issues like reddish-brown stains, metallic taste, or other signs of iron contamination in your water, it is advisable to have your water tested by a certified laboratory. A water analysis will help determine the iron concentration and guide you in choosing the appropriate iron filtration system.
Do i need a water analysis?
If you are interested in one of our unique iron filtration systems we first recommend getting a water sample from a laboratory so we can determine which system is best for you.
Yes, we can do the samples for you. Call us on (08) 9209 3330 to arrange a water sample.
How does Iron get into the water?
Iron typically comes from the rocks and soils around the water source. As water moves through the rocks and into the aquafer, it dissolves the iron that is naturally found in the environment.
Iron is the metal that is most abundant on Earth and is therefore very common in soils and groundwater. Dissolved iron occurs naturally in groundwater in concentrations of up to around 50 mg/L. Iron salts become increasingly soluble as groundwater becomes more acidic. In oxygen deprived and acidic groundwater (with a pH below 5), iron concentrations of between 1 and 20 mg/L are common (usually as stable carbonates). Iron is normally found dissolved in groundwater in the reduced ferrous form (Fe2+) and oxidises to relatively insoluble ferric form (Fe3+) when the pH of groundwater (alkalinity) is raised and it is exposed to oxygen in the air.
When acidic iron-rich groundwater is extracted and mixes with air, carbon dioxide and hydrogen sulfide (rotten egg gas) is frequently released, the pH rises and the iron is deposited as ferric hydroxide (rust) on any flat surface as water evaporates. Over time this oxide coating builds up causing discolouration particularly to light-coloured surfaces.
Iron may also be naturally present in groundwater as slimy, sometimes foul smelling bacteria filaments (such as Acidithiobacillus ferrooxidans). These bacteria are harmless, unlikely to settle out, and discolour the water brown, often with an oily sheen.
Iron deposits and iron bacteria may cause encrustations and blockage problems in irrigation systems, especially those that rely on small orifices for pressure control or delivery via water drippers. Iron scale may also affect heat transfer in hot water systems.
Iron staining is unsightly, but shouldn’t cause serious harm to plants, animals or humans or structural damage. With high concentrations of iron (more than 20 mg/L) some plants with iron staining may experience a reduction in photosynthesis and vigour.
Where is iron staining likely?
Acidic iron-rich groundwater is often found in the water-table close to present or past wetlands where organic carbon and sulfides are prevalent; the water table is shallow and contains little or no dissolved oxygen. Prior to drilling a well, it is wise to check with neighbours to see if they have experienced iron problems with their bore water. Old or damaged galvanised steel pipe-work may add to iron staining problems as acidic waters attack pipe walls.
When there are high levels of iron in water, you will see this from the black and red stains left by the minerals. These stains accumulate and build up deposits in pipes and the areas around it. You often see paving, concrete, garden walls etc stained with this mineral which has not been treated. Often untreated iron can cause significant damages to the surrounding areas over time. Replacing these damaged areas can be an expensive and short term solution which will result in the same damages from the iron over time. The iron in the water can lead to environmental damage of the surrounding areas to nature, trees and wildlife. The iron damage in the area can affect the integrity of assets, including; playground equipment, benches, structures, poles, buildings and more. Iron may also stain clothes washed in iron-rich water and plumbing fixtures such as basins and toilet bowls. These rust stains resist cleaning with soaps, detergents and bleach.
Can an iron filtration system remove existing iron stains?
Once an iron filtration system is installed and effectively removing iron from your water supply, it can prevent further staining. However, existing iron stains on surfaces may require additional cleaning methods or stain removers specifically designed for iron stains.
