NanoDose™ pH Control Dosing Kit

Automatic pH correction for acidic borehole and wellpoint water: a pH probe controls the dosing pump to hold your water at the set point. Chemicals not included.

What it is for

Acidic water (low pH) corrodes copper pipes, geysers and fittings, can leave blue-green stains, and stops iron and manganese removal working properly. This kit raises the pH into the correct range and holds it there automatically.

Why pH matters for iron and manganese removal

Acidic groundwater must first be neutralised – its pH raised with an alkalising treatment such as soda ash – to reach the target pH before iron and manganese can be removed:

• Iron oxidation typically needs a pH of 7.0 or higher.
• Manganese oxidation needs a higher pH, around 7.2–8.5.

Reaching this pH is critical: below it, the iron and manganese stay dissolved and the removal stages that follow cannot do their job.

How it works

The pH probe continuously measures the water and the Etatron DLX controller doses alkali only as much as needed to reach your set point – typically pH 7.5–8.5 – so you don’t under- or over-dose as the raw water changes.

Recommended chemicals

• Sodium carbonate (soda ash) – best for a starting pH of about 4.0–6.9. It buffers, adding pH and alkalinity gradually, which prevents overshooting. The usual choice.
• Caustic soda (sodium hydroxide) – for very acidic water below about pH 4.0. A strong base that moves pH quickly but buffers poorly, so it needs precise control and careful handling.

What’s included

• Etatron DLX pH dosing pump & probe kit – up to 20 L/h, up to 20 bar, with pH probe for automatic control.
• 100 L chemical dosing tank – choose Blue for outdoor installation or Clear for indoor installation (lets you see the level at a glance).

Not included

• Soda ash or caustic soda – we’ll recommend which suits your water.
• Why chemicals are separate: treatment chemicals are heavy and expensive to ship, so it is usually far cheaper to buy the recommended chemical from a supplier near you. We’ll tell you exactly which chemical and strength to buy, and it is also available from us as a separate product.
• Installation (available on request).

Always use it with recirculation

This kit should always be used together with a recirculation pump – or, preferably, with one of our First-Stage Complete Assembly Kits. Keeping the tank water moving past the probe gives uniform pH correction through the whole tank and much more accurate control of the dosing.

• Why: on a one-way incoming pipe the water reaches the tank before the chemical has reacted, so the probe never reads the true pH and the pump over- or under-doses. On a recirculation loop the probe reads the real, mixed tank water.
• First-Stage Complete Assembly Kits (NanoJet™ VORTEX™, FUSION™ or CYCLONE™ Borehole Pressure-Boost Kits, sized to your tank) provide the pump, venturi injector and NanoJet™ turbulence reactor: the probe sits on the loop and the alkali is dosed into the venturi, so it is drawn into the jet and spread evenly through the tank.
• Want it all in one box? The NanoDose™ Standalone pH Control Recirculation Kit combines this pH kit with a First-Stage assembly, float switch and connectors.

Safety

Caustic soda is highly corrosive and soda ash is an irritant. Wear gloves and eye protection and always add the chemical to water, never water to the chemical.
