Blue Spot Water

Features :

Ultra Low Pressure (ULP) Operates at $\approx 2/3$ the pressure of conventional RO membranes.

Significant energy savings and reduced wear on pumps and system components.

High Salt Rejection Stable rejection rate of $\ge 99.0\%$.Consistently produces high-purity water by effectively removing salts, heavy metals, and dissolved solids.

High Flow Rate Average Permeate Flow of 950 GPD ($\approx 3.6{\text{ m}}^3/\text{d}$).Handles medium-volume water requirements efficiently.

Brackish Water Ready Recommended for feedwater TDS concentrations up to 2,000 ppm.Suitable for treating surface water, borehole water, and municipal water sources.

What does it do:

• Purifies Water: It is the core component of a Reverse Osmosis system, acting as an extremely fine, semi-permeable barrier. It physically separates almost all dissolved salts, inorganic molecules, heavy metals, and microscopic contaminants (like bacteria and viruses) from the feed water.

• Saves Energy (ULP Feature): The "ULP" stands for Ultra Low Pressure. This is its main selling point. It achieves the high level of purification mentioned above while operating at a significantly lower pressure (about two-thirds less) than traditional RO membranes, which results in lower electricity consumption for your water treatment system.

• Produces High-Quality Water: It achieves a salt rejection rate of $\ge 99.0\%$, making the treated water suitable for demanding commercial and industrial uses like producing bottled drinking water, feeding industrial boilers, and use in pharmaceutical manufacturing.
