Two-Stage DTRO Wastewater Treatment Equipment
March 26, 2026
Overview
Two-Stage Disc Tube Reverse Osmosis (DTRO) equipment is an advanced membrane separation technology specifically designed for high-concentration wastewater treatment, particularly landfill leachate and industrial effluent.
Working Principle
The system operates in two sequential stages:
- Stage 1: Raw wastewater passes through DTRO membranes, removing 85-90% of contaminants
- Stage 2: Permeate from Stage 1 undergoes further filtration, achieving 95%+ purification efficiency
