Filter for domestic borehole

The use of well water from a domestic borehole allows significant savings compared to municipal water. This is particularly useful for applications requiring high volumes of water: car wash station, irrigation system or geothermal heat pump.
But this water is not always of good quality. Water from wells and boreholes is often loaded with sand, mud or clay. To avoid time and cost of cartridges frequent replacement, Hectron offers several solutions without consumables.



Alfa hydrocyclones are the most economical solution in the presence of sand. They require manual interventions to drain the tank, but much less frequently than on a cartridge filter.

Water quality

  • Removes 80% of particles above 100 microns


  • Manual drain
filtre automatique prago

Prago have the advantage of being fully automatic. They are efficient for sand removal. They can operate on networks between 0 and 6 bar pressure.

  • Filtration degree up from 100 microns
  • Fully automatic

AG range filters are also fully automatic. It is the most efficient solution for optimum water quality, even if water is loaded with very fine particles. They are recommended in the presence of clay or for potabilization applications

  • Filtration degree from 0,5-1 micron
  • Fully automatic


What protection for a heat pump on groundwater?
Tubular heat exchangers usually do not require any protection. Plate heat exchangers are more efficient, but also more sensitive to fouling. In the presence of sand, choose a hydrocyclone or Prago. In the presence of soil or clay, finer filtration is required to avoid deposits. The AG100 solution is the most recommended.

Is it possible to drink the water from a well or borehole?
The filtration step can remove particles and water coloration. But it is essential to add after the filter a system against bacteria, usually a UV. Other contaminants may be present ; a physico-chemical analysis of water is therefore essential.

Will the filter make my water crystal clear?
Colored water indicates the presence of very fine suspended solids. AG100 filters are an efficient solution in 99% of cases, but it may occur that the suspended solids are too thin to be removed by these filters. Do not hesitate to send us a water sample for validation.

Hydrocyclone or Prago automatic filter? 
With both solutions, water quality will be equivalent. The difference is for maintenance: the Prago is fully automatic, while a hydrocyclone has to be drain manually, about once a month.
