Blue Spot Water

Features : RO Membranes are the core of pure water systems. Achieve up to 98% contaminant rejection, removing dissolved salts, heavy metals, bacteria, and viruses.

The GPD (Gallons Per Day) rating is the key metric indicating the membrane's water production capacity. This number tells you how many gallons of purified water the membrane can produce in a 24-hour period under optimal conditions.

We offer a range of capacities to suit every need, from residential to light commercial:

What does it do:

Reverse Osmosis (RO) membranes are the heart of any RO system, functioning as a sophisticated barrier against nearly all water contaminants. These semi-permeable membranes achieve an incredibly fine filtration level of 0.0001 micron, a precision unmatched by standard filters.

This ultra-fine filtration effectively expels up to 98% of:

• Dissolved Salts (TDS)

• Heavy Metals

• Bacteria and Viruses

• Other Impurities

The result is consistently clean, great-tasting drinking water. We supply high-quality membranes from trusted manufacturers like Sinoflow, Vontron, and Linki.

How RO Membranes Work: The Thin-Film Composite (TFC) Advantage

Most high-performance membranes utilize Thin-Film Composite (TFC) material—a sophisticated, multi-layered structure designed for maximum efficiency and durability:

1. Polyamide (PA) Layer: The primary filter. This ultra-thin top layer allows only water molecules to pass through while rejecting contaminants.

2. Polysulfone (PSF) Support Layer: Provides essential structural integrity beneath the polyamide.

3. Polyester (PET) Support Web: The bottom layer, adding overall strength and stability.

This construction ensures high contaminant rejection, excellent pressure resistance, and long-term durability.

Maintenance:

RO membrane replacement is necessary when the membrane performance degrades, as confirmed by one of the following signs:

1. Reduced Flow Rate: The system produces water much slower than its rated GPD capacity (e.g., 400 GPD system only produces 100 GPD).

2. Increased TDS/Contaminants: The purified water begins to show higher Total Dissolved Solids (TDS) readings, indicating the membrane is deteriorating and allowing impurities to pass through.

3. Timeframe: RO membranes typically last between 1 to 3 years, depending heavily on the quality of your feed water and whether pre-filters are changed rigorously every 6–12 months.

Maintenance Summary: To maximise your RO membrane's life, prioritize the timely replacement of your sediment and carbon pre-filters—this is the most cost-effective maintenance strategy.
