# Softeners for Oman's *hard inland water.*

Coastal mains in Oman is desalinated and soft. Inland it is a different story: a 2024 study of Al Dhahirah groundwater found an average total hardness of about 659 mg/l. Water like that crusts heaters, taps and shower glass quickly. Regal takes the calcium and magnesium out first, from an under-sink unit for a villa to twin vessels for a hotel or farm.

How softening works

## How the resin *pulls hardness out.*

The softener holds a bed of resin beads charged with sodium. Hard water flows through, and the beads swap that sodium for calcium and magnesium, the minerals that form scale. These are the parts of a metered softener at work.

Hard water Soft water Brine To drain

1.  1

    **Bypass valve**

    Isolates the softener for servicing while keeping water flowing to the building.

2.  2

    **Control valve**

    Routes water through each stage and runs regeneration automatically.

3.  3

    **Water meter**

    Counts every litre of soft water, so regeneration happens only when the resin is nearly spent.

4.  4

    **Mineral tank**

    The pressure vessel. Headroom above the resin lets the bed lift and clean itself on backwash.

5.  5

    **Ion-exchange resin**

    Beads charged with sodium. Calcium and magnesium stick to them and sodium is released.

6.  6

    **Riser tube & distributor**

    Soft water is collected at the base of the tank and rises up the centre tube to the outlet.

7.  7

    **Salt & brine**

    Salt dissolves in the water at the base of the tank to make the brine used to recharge the resin.

8.  8

    **Brine well & safety float**

    Draws brine out and meters the refill. The float stops the tank from overfilling.

9.  9

    **Drain with air gap**

    Carries rinse water away. The air gap stops drain water from ever siphoning back.

10.  10

     **Drinking tap**

     Teed off before the softener, so one kitchen tap stays on unsoftened water.

The regeneration cycle

## Recharging, *only when it's needed.*

When the meter shows the resin is nearly used up, the valve starts a regeneration, straight away or at a set time such as 2 am. On a twin set the second vessel takes over, so soft water never stops.

1.  In service

    ### Service

    Hard water flows down through the resin and leaves as soft water. The meter counts each litre used.

2.  Stage 1

    ### Backwash

    Water runs up through the tank, lifting and loosening the bed and flushing trapped sediment to drain.

3.  Stage 2

    ### Brine draw & slow rinse

    Brine is drawn from the salt tank through the resin. It strips off the calcium and magnesium and recharges the beads with sodium.

4.  Stage 3

    ### Fast rinse

    A fast flow of water resettles the bed and rinses the last of the brine and hardness to drain.

5.  Stage 4

    ### Brine refill

    A measured volume of water refills the salt tank, making fresh brine for the next regeneration.

Stages differ by valve. Some add a second backwash, and up-flow models such as the Regal 100 and 200 send brine upward through the resin to use less salt.

Why soften

## What softening *saves in a home or business.*

### Protects equipment

No scale building up

-   Water heaters stay scale-free
-   Washing machines and dishwashers keep clean elements
-   Espresso machines stay clear
-   Fewer clogged valves and shower heads

### Visible every day

Around the house

-   Soap and shampoo lather easily
-   Glasses dry without marks
-   No white crust on taps and screens
-   Much less descaling

### Cheap to run

Made for daily use

-   Metering saves salt and water
-   Proven Clack and CE valves
-   Low-power controls
-   Serviced by our Oman partner

Why Regal

## Any size, *the same build quality.*

Every Regal uses metered regeneration and proven valves, so a villa in Ibri and a hotel in Nizwa get the same engineering, scaled to the job.

-   Sized to your source and your flow
-   Pairs with Regent filtration for silty wells
-   A separate unsoftened drinking tap, as standard practice
-   Maintenance plans from a fixed annual fee

Your questions answered

## Water softeners in Oman, *simply answered.*

Q1Do I need a softener in Muscat?

Usually not if the building is on Nama's desalinated mains, which is soft. A softener earns its place inland, on wells and on hard groundwater.

Q2How does a softener work?

Resin inside the tank holds on to calcium and magnesium as water passes and lets go of sodium instead. The water that comes out no longer leaves scale.

Q3Which Regal is right for us?

Villas usually take a Regal 100 or 150, and larger villas or small kitchens a Regal 200. Hotels and laundries suit a Regal 500; farms and plants a Regal 750 or Twin 3672. We confirm after the survey.

Q4Can we drink softened water?

Common practice is to keep one kitchen tap on unsoftened water for drinking, cooking and baby milk. We plumb it in when we fit the softener.

Q5Softener or filter?

They solve different problems. A softener removes hardness; a filter removes silt, rust and taste. Many wells need both, a Regent filter first and then a Regal softener.

Q6Who installs and services it?

Our Oman partner fits each Regal and can service it on a maintenance plan, keeping the settings right for your water.

Local notes

## Regal in Oman

Oman's water hardness depends on where you are. Coastal mains water is mostly desalinated and soft. Inland groundwater is another story: a 2024 study in Al Dhahirah found average hardness of about 659 mg/l, enough to leave scale in heaters and pipes.

Regal softeners take that hardness out. The range runs from a small unit under a kitchen sink to twin vessels for a hotel, and every one is quoted in rials.

### Common questions

Does a Muscat flat on desalinated water need a softener?

Usually not. Desalinated mains water carries little hardness. Softeners matter most for homes and sites on inland groundwater or a private well.

What does a softener actually do?

It swaps the calcium and magnesium that cause scale for sodium. It does not disinfect, so a well supply still needs UV as the last step.

Can soft water keep flowing during regeneration?

On the Regal Twin 3672, yes. Two vessels take turns, and up to six units can share one controller.

In Oman

## Specified, installed and looked after anywhere in Oman

Coastal mains water is mostly desalinated seawater. It is soft, but it picks things up in pipes and tanks. Inland wells can be very hard: one 2024 study of Al Dhahirah groundwater found an average hardness of 659 mg/l.

Say which governorate you are in, whether the water comes from the Nama network, a tank or a well, and what you need it for. We design the system, price it in rials and arrange the fit.
