Drinking Water Production
Raw Water Sources
Drinking water is produced by removing suspended solids, microorganisms and dissolved gases from raw water sourced from groundwater or surface waters such as lakes, rivers and reservoirs. Groundwater is extracted from wells, while surface water is collected from open sources; both types are treated through multi‑step purification before distribution.
Conventional Treatment Steps
Treatment combines mechanical filtration, chemical processes and biological treatment to eliminate visible and invisible contaminants. Typical steps include coagulation/flocculation and sedimentation or sand filtration to remove particles, activated carbon to adsorb organic compounds and taste/odor issues, and UV disinfection as an extra safety barrier against microbiological contamination. Pressure filters (chemical‑free) are commonly used to remove iron, manganese, ammonium and to reduce water aggressiveness. Where chlorine is used for residual disinfection, granular activated carbon can be employed downstream to protect subsequent processes.
Advanced Contaminant Removal
Modern plants must also address emerging contaminants such as microplastics and pharmaceutical residues; solutions include advanced membrane filtration (UF/NF/RO) and biodegradation technologies to remove very small or persistent compounds. The exact combination of techniques depends on raw‑water chemistry and regulatory targets.
How We Can Help
Enwa helps customers secure safe drinking water by starting with site‑specific water analysis and recommending the right treatment train—whether groundwater or surface water.
