This is the process that allows to take off the water all suspended solids which cause the turbidity of the water, like sludge, mud.
This process is used to filter water from wells water or from surfaces sources.

Iron removing

Iron can be contained in water as a dissolved matter or as a precipitate suspended.
This process can be made by a special media filter, able to feature both oxidation and filtration.

Water deionization

Owing to the presence of cations and anions in water, it is an electrical conductor, and its conductivity depends on the quantity of ions the water itself contains.
A deionizer system consists of several vessels filled with proper resins; the water simply flows through the resins.

Water softening

The salts of calcium and magnesium dissolved in water is the “hardness” of water. The hardness of water is usually measured as ppm (part per million) of calcium carbonate; it is also used the French degree (°Fr).
The softeners are the equipment that allow to make the softening of the water by ion exchange process.

Activated carbon filters

Activated carbon is a common coal, made of vegetable or mineral, and activated in special ovens with steam at a very high temperature.
The activated carbon is commonly used in water treatment, in air treatment, in the industry of sugar of wine production, and so on.


The water is a chemical compound, H2O (hydrogen and oxygen), but it also contains several substances.
Generally speaking, we can define the water as drinkable, when it can be safely drunk without any damages for the human health.

How to select the control for a water treatment unit

The automatic regeneration control of a softener, a filter or a deionizer, includes :
– the hydraulic control to regenerate the unit.
– another control to start the regeneration, the action of which is to decide WHEN the unit has to be regenerated.
