Waste Water Treatment Machine

Application Scope of Two-Stage RO Reverse Osmosis Systems

1. Purification of purified water, distilled water, and water used in food and beverage production.

2. Preparation of pure and ultrapure water for industries such as electronics, pharmaceuticals, and food.

3. Process engineering for separation, concentration, and liquid decolorization in industries like light textile, chemical, and food.

4. Desalination of seawater and brackish water.

Characteristics of Two-Stage Reverse Osmosis

2. High retention and removal efficiency for organic matter, colloids, particles, bacteria, viruses, and pyrogens;
3. Low energy consumption, high water recovery rate, and lower operating costs compared to other desalination equipment;
4. No phase change during separation, ensuring reliable stability;
5. Compact design, simple operation, easy maintenance, strong adaptability, and long service life;
6. Continuous operation with stable product water quality;
7. No need for acid and alkali regeneration;
8. No downtime due to regeneration;
9. Saves water used for backwashing and cleaning.

Double-Pass Reverse Osmosis Pure Water System: Ultimate Purity for Pharmaceutical Manufacturing

Introducing our Double-Pass Reverse Osmosis (RO) Pure Water System, engineered to deliver the highest grade of purified water for the most critical pharmaceutical, biopharmaceutical, and medical device applications. This advanced configuration, featuring two sequential RO membrane stages, ensures exceptional removal of ionic contaminants, endotoxins, and organics, producing water that reliably exceeds USP <645> and EP 2.2.38 conductivity specifications for Purified Water. As a cornerstone water treatment plant machine, it is designed for seamless integration within complex pharmaceutical facilities, performing reliably as a critical industrial water treatment machine while minimizing waste and supporting sustainable operations. Its efficiency in concentrate reduction also makes it a vital upstream component in the broader network of waste water treatment machine systems, helping to lower overall effluent volume and treatment costs.

Two-Stage Purification for Unmatched Quality

The double-pass RO design provides an unparalleled level of purity assurance. In the first pass, raw feed water undergoes initial purification, removing the majority of dissolved solids. The permeate from this stage is then fed directly into a second RO unit for a final polishing stage. This sequential filtration delivers significantly lower conductivity and total organic carbon (TOC) levels compared to single-pass systems. Constructed with 316L stainless steel and sanitary fittings, this industrial water treatment machine is built to prevent microbial ingress and biofilm formation, featuring fully automated Clean-in-Place (CIP) cycles and 21 CFR Part 11-compliant data logging for full validation and operational control.

Engineered for Integration and Environmental Efficiency

This system is not a standalone unit but a synergistic water treatment plant machine designed for the pharmaceutical ecosystem. Its high recovery rate optimizes water usage, directly reducing the volume of concentrated brine (reject water) sent for disposal. This function is crucial, as it lowers the hydraulic and salinity load on downstream waste water treatment machine systems, such as evaporators or crystallizers, leading to significant operational savings and enhanced environmental compliance. By treating the RO concentrate as a manageable by-product, our system transforms a standard purification unit into a proactive component of responsible plant-wide water management, complementing other industrial water treatment machines within your facility.
