Hidrowater

Hidrowater home systems operate optimally within a pressure range of 2.5 to 6 bar. Some in-line consumables and technical housings withstand a certified maximum static pressure of up to 8.75 bar to prevent damage from water hammer.

If the water supply delivers less than 2.5 bar, it is essential to install a model with an integrated pressure pump to ensure the reverse osmosis membrane can separate molecules without wasting water down the drain.

A Hidrowater volumetric water softener reduces the concentration of calcium and magnesium ions to the exact levels you choose using the built-in mixing valve. Removing 100% of the hardness is not recommended, to prevent the water from becoming corrosive to copper pipes.

To protect boilers and recirculation systems, it is advisable to adjust the outlet water to between 5 and 8 French degrees of hardness. The cation-exchange resin retains limescale and regenerates automatically as salt is used, optimizing the property's preventive maintenance.

The technical difference lies in the filtration pore size and the production of wastewater during the purification cycle.

• Reverse osmosis removes dissolved salts, viruses, and heavy metals using a semipermeable membrane that requires flushing to the drain.
• Ultrafiltration retains the minerals in the water and operates without wastewater, using hollow-fiber cartridges.
• Compact cartridges feature a 1/4-inch push-fit connection for quick, tool-free replacement.

Hidrowater's compact direct-flow reverse osmosis and ultrafiltration series are specifically designed for standard kitchen cabinets 60 centimeters deep. These frames house the sediment, carbon block, and post-filter stages in a protective vertical casing, eliminating bulky pressurized tanks.

To confirm the technical fit for your installation before buying, check the measurements in millimeters published in each system's product specifications on our official platform.

The replacement schedule depends on the volume consumed and the water's turbidity, but follows predictable technical intervals in household installations.

• Sediment pre-filter and activated carbon cartridges: must be replaced every 6 to 12 months to prevent saturation and chlorine leakage.
• Reverse osmosis membrane: replace every 24 to 36 months, checking the permeate conductivity with a TDS meter.
• Remineralizing or bactericidal post-filter: replace annually along with regular pre-filter maintenance.

Pre-dechlorination using activated carbon cartridges is essential to protect the filter membranes, but it leaves the stored water without residual disinfectant to prevent microbial growth. If the processed water remains stagnant in pressure tanks, adding a final ultraviolet treatment stage or antibacterial post-filters is recommended.

This additional treatment eliminates pathogens without altering the mineral balance or the taste of the water intended for everyday household consumption.

The nominal flow rate should be calculated by adding up the simultaneous consumption of the outlets planned for the home or pool. A standard apartment needs a continuous flow of 1.5 to 2 cubic meters per hour, while single-family homes with irrigation or chemical dosing require higher-capacity technical manifolds.

Choosing an undersized pipe diameter causes faucets to lose flow when several are running at once during peak-demand hours.
