Q
How does Ecolite Ultrasoft differ from Ecolite Soft in terms of water softening?
Ecolite Ultrasoft has uniform spherical beads that provide smoother flow, lower pressure drop and faster ion exchange kinetics compared to Ecolite Soft. This provides higher efficiency and stable performance in compact or high flow systems.
Can Ecolite Ultrasoft be used in high flow or commercial systems?
Yes. Its uniform particle size provides stable performance in domestic, commercial and industrial applications where low pressure drop and high flow rate are important.
Is pre-filtration required?
Yes. It is recommended to install a sediment pre-filter (20-100 µm) before the softener to prevent clogging and extend the life of the resin.
Can Ecolite Ultrasoft be used for iron removal?
It is primarily intended for hardness removal. For water with high iron content, a specialized mixed media ECOMIX® is recommended.
What is the typical service life of Ecolite Ultrasoft?
Under normal operating conditions, the resin lasts for approximately 3-5 years, depending on the water quality and the frequency of regeneration.
How can I find out the volume capacity of Ecolite Ultrasoft in my system?
This can be calculated using the formula:
Volume capacity (m³) = Ecolite Ultrasoft volume (L) × [Ion exchange capacity (g CaCO₃/L) ÷ Inlet hardness (ppm CaCO₃)],
where the ion exchange capacity of Ecolite Soft is 60 g CaCO₃/L.
For example, if the Ecosoft 16×65 water softener is filled with 125 l Ecolite Ultrasoft and the inlet water hardness is 200 ppm CaCO₃, the volume of treated water before regeneration will be 37.5 m³.
