Frequently Asked Questions

For how many people is this 3750 liter water purifier recommended?

This model is specifically designed for homes, second homes or country houses regularly inhabited by 4 to 5 people, ensuring that the volume of treated wastewater meets the required purification standards.

Does it produce bad smells during operation?

No. Thanks to the total oxidation system through continuous or sequential aeration, organic matter is degraded through aerobic processes that completely prevent the appearance of sulfurous gases that cause the bad odors typical of traditional septic tanks.

What maintenance does the GA90028 water treatment plant require?

Maintenance is minimal and is limited to periodic checks of the air blowing system and emptying the sludge accumulated at the bottom of the pit, the frequency of which will depend on the actual use, usually being done once a year or every two years.

Is the adjustable cover suitable for withstanding vehicle traffic?

The adjustable cover is designed for easy installation in landscaped or pedestrian areas. If vehicle traffic or parking is expected over the installation area, specific reinforcement accessories to support rolling loads should be consulted.

Is constant electricity consumption mandatory?

Yes, the total oxidation system requires the air compressor to operate on a programmed schedule to inject oxygen into the water and keep the microorganisms responsible for breaking down waste alive. However, the energy consumption of these motors is extremely low, comparable to that of a conventional light bulb.
