Key Design & Features

๐Ÿ”ง Pre-treatment System

Coagulation and Sedimentation: Raw feed water is pumped to a coagulation tank for the removal of larger particles. The process uses tube settlers to enhance sedimentation efficiency.

Multimedia Filters (MMF): Designed to remove suspended solids and reduce the Silt Density Index (SDI) of feed water, with backwashing utilizing RO reject water.

๐Ÿ’ง Reverse Osmosis System

High-Pressure Pumps: Designed for optimal feed flow and pressure to maximize recovery rates.

RO Membrane Technology: Polyamide composite membranes provide 99.8% salt rejection and produce water with <500 mg/L salinity.

Two-Stage RO Configuration: Improves recovery rates and permeate water quality.

๐Ÿงช Post-treatment System

UV Sterilization Unit: Provides effective disinfection, ensuring microbial safety in treated water.

Chemical Dosing Systems: Includes dosing of anti-scalants, sodium bisulfite (SMBS), and pH adjustment for process optimization.
