Removing Contaminants with RO: A Guide to TDS Reduction
Removing Contaminants with RO: A Guide to TDS Reduction
Understanding TDS: What Are Total Dissolved Solids?
Total Dissolved Solids (TDS) represent the combined content of all inorganic and organic substances contained in water. Measured in parts per million (ppm), TDS includes minerals, salts, metals, and other compounds that have dissolved in water from natural and man-made sources.
Common TDS Components:
- Calcium and magnesium (water hardness)
- Sodium and potassium
- Bicarbonates and chlorides
- Heavy metals (lead, arsenic)
- Agricultural and industrial runoff
The Health and Operational Impact of High TDS Levels
Practical Concerns with Elevated TDS:
- Unpleasant taste and odor in drinking water
- Scale buildup in pipes and appliances
- Reduced efficiency of soaps and detergents
- Potential corrosion in industrial equipment
- Compliance issues with water quality standards
TDS Concentration Guidelines:
- Excellent: 0-300 ppm
- Good: 300-600 ppm
- Fair: 600-900 ppm
- Poor: 900-1200 ppm
- Unacceptable: 1200+ ppm
RO Technology: The Gold Standard for TDS Reduction
How Reverse Osmosis Works:
Reverse osmosis employs a semi-permeable membrane and applied pressure to separate dissolved solids from water molecules. The process forces water through microscopic pores while rejecting contaminants based on molecular size and electrical charge.
The Multi-Stage RO Process:
- Pre-filtration: Removes sediment and chlorine
- RO membrane: Primary TDS reduction stage
- Post-filtration: Polishing for final water quality
- Remineralization: Optional taste enhancement
