My well water here in Buri Ram is very hard - the soap lather is poor. What are the least technical options for softening well water?

I think Ion Exchange it the most common.

Have the water tested before firing the new parts cannon.

Our well water used for product cleaning is manganese rich and clogs resin softeners over time.

I agree. First get the water tested and a plan of action.

It would be work with a professional on putting a system together.

Completely agree with others and get it tested.

This is our system, without the water softener as we have mainly iron in the water.

From the submersible pump into a Big Blue sediment filter, then 3000L tank, 2 automatic backwash filters, a chlorine infuser but no water softener filter.

A float switch in the tank starts and stops the submersible pump. :)

A 3-litre sample of well water will be submitted next Monday to Rajabhat University for laboratory testing. The test results are expected to be available by the following Friday.

I agree about testing. This is the first step in deciding what equipment will be required to produce minimal mineral water.

When I had my borehole drilled (51 metres) my water test showed loads of calcium carbonate in amongst others. This was due to gypsum rock deep underground.

The water was so hard that no amount of resin would fix it. Many metal water fittings including the jet pump venturi, which completely disintegrated, were affected.

I stopped using the borehole water pretty quick and went exclusively with a 5.5 meter surface water well. Filters are zeolite, carbon and resin.

The zeolite is good for many things including ion exchange which deals with heavy metals and softens water but also it's millions of tiny pores are very good

at capturing suspended particles in the water. Then there is a carbon filter which collects more of the same but not quite so well

then on to the resin filter which may seem redundant but, unlike the zeolite it should never need replacement. This is due to a rejuvenative saline cycle.

The best people to see about water treatment in Buriram are a company called PP Water. They have a website.
