The problem

Off-the-shelf treatment rarely matches your water

Two sites five kilometres apart can have completely different hardness, TDS and turbidity. A water treatment plant sized for one and installed at the other under-performs from day one — or costs more to run than it should.

Scale & hardness damage

Untreated hard water scales pipes, heaters, RO membranes and appliances, shortening their working life.

Unreliable process water

Factories running high-TDS or turbid feedwater through sensitive equipment risk fouling and downtime.

Oversized, overpriced systems

Generic packages sized without a water test either under-treat or add capacity — and cost — you don't need.

Water Softener Plant

Stop scale before it reaches your pipes

Ion-exchange water softener plants remove calcium and magnesium hardness at the point of entry, protecting downstream pipework, water heaters, RO membranes and appliances from scale build-up.

Industrial RO Plant

Purified process water at factory scale

Industrial RO plants remove dissolved salts and contaminants through a semi-permeable membrane, producing consistent low-TDS water for boiler feed, process use or drinking water applications.

Pre-treatment matched to your feed water quality
Membrane banks sized to required output capacity
Reject-water management built into the design

Pressure Sand Filter

The first line of defence against turbidity

A pressure sand filter (PSF) removes suspended solids, silt and turbidity through graded sand media, protecting downstream softeners, RO membranes and equipment from fouling.

Activated Carbon Filter

Remove chlorine, odour and organics

An activated carbon filter (ACF) uses adsorption to remove residual chlorine, organic compounds, taste and odour — commonly placed after the PSF and before a softener or RO membrane to protect it.

Figures are indicative starting ranges for planning only — final sizing for your water treatment plant is confirmed against a water test and your actual demand.

Why Neptune

Benefits of treatment sized to your water

Longer equipment life

Correctly treated water protects pipes, heaters, membranes and appliances from scale and fouling.

Predictable running cost

Right-sized softener, RO and filtration stages avoid over-provisioning and unnecessary media/chemical use.

Consistent output quality

Multi-stage treatment trains hold their output quality even as source water quality varies seasonally.

FAQs

Water treatment solutions — common questions

What is a water softener?+

A water softener removes dissolved calcium and magnesium (hardness) from your water supply using ion-exchange resin, preventing scale build-up in pipes, heaters and appliances. It's typically installed at the point where water enters a home, building or process line.

How does an RO plant work?+

A reverse osmosis (RO) plant forces source water through a semi-permeable membrane under pressure, rejecting dissolved salts, minerals and most contaminants while producing purified permeate water. Industrial RO plants add pre-treatment, membrane banks and reject-management sized to your feed water quality and required output.

What's the difference between a pressure sand filter and activated carbon filter?+

A pressure sand filter (PSF) removes suspended solids, turbidity and sediment through graded sand media, and is usually the first stage of treatment. An activated carbon filter (ACF) removes chlorine, organic compounds, odour and taste using adsorption, and is typically installed after the PSF or before an RO membrane to protect it.

Do you supply industrial RO plants for factories?+

Yes. Neptune designs and installs industrial RO plants sized to factory feed water quality, required output capacity and downstream process requirements, with AMC support after commissioning.
