Specialty Water Treatment

Iron produces orange, red or brown staining and a metallic taste. The critical distinction is the form it's in. Dissolved (clear-water) iron looks clear at the tap and turns orange after sitting. Oxidised (red-water) iron arrives already discoloured.

Most approaches involve converting dissolved iron into a filterable form and then removing it. Which media and which oxidation method suit your water depends on the level, the pH, and whether manganese is present alongside it. Iron bacteria — a slimy reddish residue in toilet tanks and fixtures — is a different problem again and often requires disinfecting the well as well as filtering.

Manganese shows up as black or dark brown specks and staining — in the toilet tank, on fixtures, in the dishwasher, on laundry. It's frequently found alongside iron and is generally the harder of the two to treat.

The reason is pH. Manganese typically needs a higher pH to oxidise than iron does, which means a system sized and configured for iron alone may handle the orange and leave the black behind. Where pH is too low, correcting it first isn't optional — it's what makes the rest of the treatment work.

The rotten-egg smell. Before anything is specified, one question matters more than any other: is the smell in all your water, or only the hot?

Hot-water-only odor usually points to the water heater rather than the supply — a reaction involving the heater's anode rod. That's addressed at the heater, and installing whole-house treatment won't fix it. Where the odor is in the cold water too, the source is the supply, and treatment generally involves oxidation followed by filtration, or aeration, depending on the concentration and what else is present.

Sand, silt, clay, rust flakes or scale particles carried along in the water. It clouds the water, collects in fixtures, fouls aerators and wears on valves and any equipment downstream.

Filtration here is straightforward in principle but the right filter depends on what the particles actually are and how much of them there is. Light, consistent loads suit cartridge filtration. Heavier loads call for a backwashing system so you're not changing cartridges constantly. Larger, heavier material like sand may need a spin-down separator ahead of everything else.

Sediment filtration is almost always the first stage — it's what protects everything behind it.

Acidic water — pH below neutral, usually with low alkalinity — is corrosive to metal plumbing. The clearest signs show up on your pipes and fixtures: blue-green staining, accelerated corrosion of fittings, and in more advanced cases pinhole leaks in copper pipe.

The common approach is a neutralising filter, where water passes through a bed of media that dissolves slowly and raises pH. It's effective and straightforward, with one consequence worth knowing upfront: it generally adds hardness, which is why a softener frequently follows it. Where pH is very low, or where adding hardness isn't desirable, a metered chemical feed may be the better route.

pH correction also has to come first when iron or manganese treatment depends on adequate pH to function.

Most specialty work we do is on private wells, and most of those wells have more than one condition. Iron with hardness. Sulfur with iron. Low pH keeping everything dissolved and making the rest harder to treat.

That's a design problem rather than a product problem. The answer is a staged system where each component handles one thing and protects the next, in an order determined by the chemistry — not by what's easiest to install.
