Engineering Analysis
The RO membrane removes dissolved salts, heavy metals, and contaminants, reducing TDS from raw levels to safe drinking standards. UV sterilisation eliminates bacteria, viruses, and microorganisms with 99.99% efficacy without adding chemicals. UF membrane filtration acts as a secondary barrier catching colloidal particles and biological matter larger than 0.01 microns. The 7-stage system ensures multi-layer protection across sediment, chemical, and microbial contaminants.
