Wastewater Treatment Plant Equipment

Reverse Osmosis (RO) is the most precise membrane-based liquid separation technology. It can block almost all dissolved salts and organic compounds with a molecular weight greater than 100, allowing only water molecules to pass through. The salt rejection rate of RO composite membranes is typically over 99%. RO is widely used in seawater and brackish water desalination, boiler feed water treatment, production of industrial pure water and electronic-grade ultrapure water, drinking water preparation, and water reclamation/reuse. Using RO before ion exchange can significantly reduce operating costs and wastewater discharge.
  • INTRODUCTION

Principle of Reverse Osmosis Separation

 

When equal volumes of a dilute solution and a concentrated solution are placed on opposite sides of a container separated by a semi-permeable membrane, the solvent from the dilute solution will naturally pass through the membrane and flow toward the concentrated solution side. The liquid level on the concentrated solution side will rise to a certain height compared to the dilute solution side, creating a pressure difference that establishes osmotic equilibrium. This pressure difference is the osmotic pressure. If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the solvent from the concentrated solution will flow toward the dilute solution. This direction of solvent flow is opposite to the original osmotic direction, and this process is called reverse osmosis.

Pharmaceutical-Grade Reverse Osmosis (RO) Pure Water System: Engineered for cGMP Compliance and Sustainability

 

Introducing our high-purity Reverse Osmosis (RO) Pure Water System, an integral component for any compliant pharmaceutical, biotech, or medical device manufacturing facility. This advanced system is specifically designed to produce Water for Injection (WFI) feed water, Purified Water (PW), and ultra-pure process water that meets or exceeds USP, EP, and cGMP standards. Engineered with efficiency and environmental stewardship in mind, our RO system minimizes water waste and can be seamlessly integrated with a comprehensive wastewater treatment equipment list to form a closed-loop water management solution. This makes it not only a source of critical purity but also a key waste water treatment machine that reduces effluent load, supporting the operational and sustainability goals of a modern wastewater treatment plant equipment infrastructure.


Core Technology for Critical Pharmaceutical Water Standards

 

Our RO system utilizes a multi-stage purification process, including pre-filtration, antiscalant dosing, high-pressure reverse osmosis membranes, and often post-treatment UV and ozone sanitation. It effectively removes up to 99.5% of ionic contaminants, bacteria, endotoxins, and organic particles, delivering consistent water quality essential for drug formulation, cleaning, and sterilization processes. The system is constructed with 316L stainless steel for PW loops and high-quality, sanitary-grade components for WFI applications, featuring automated CIP (Clean-in-Place) and data logging for full validation and compliance.


Integral to Sustainable Plant Water Management

 

In pharmaceutical manufacturing, water conservation and responsible discharge are paramount. Our RO system is designed with a high recovery rate to minimize concentrate (reject water) volume. However, the reject stream and other process effluents require proper handling. This is where our expertise extends beyond pure water generation. We provide holistic water solutions, ensuring the RO system is optimally paired with complementary wastewater treatment plant equipment. The concentrate can be effectively managed by downstream units featured on a complete wastewater treatment equipment list, such as:

  • Evaporators/Crystallizers: To further reduce volume and recover solids.

  • Membrane Bioreactors (MBRs): For treating organic-laden process waste.

  • Neutralization Tanks: For pH adjustment prior to discharge or further treatment.

In this context, the RO unit functions as both a primary purification waste water treatment machine and a crucial first step in reducing the hydraulic and contaminant load on the final effluent treatment stage.


Key Features & Operational Benefits

 

  • High-Efficiency RO Membranes: Provides maximum purity with optimized water recovery, reducing both operating costs and wastewater volume.

  • Fully Automated & Validatable: PLC-controlled with SDI (Silt Density Index) monitoring, pressure control, and full compliance with 21 CFR Part 11 for data integrity.

  • Sanitary & CIP-able Design: Prevents microbial proliferation and ensures long-term, reliable operation with minimal downtime.

  • Scalable & Modular: Systems are available from pilot-scale to large industrial capacities, designed for easy integration into existing pure water loops and wastewater treatment plant equipment networks.

  • Comprehensive Support: Includes design, installation, commissioning, and validation (IQ/OQ/PQ) support, along with guidance on integrating with your site's wastewater treatment equipment list.


Applications in Pharmaceutical Manufacturing

 

  • Production of WFI and Purified Water for drug substance and drug product manufacturing.

  • Cleaning and Rinsing of equipment and process vessels.

  • Laboratory Water for analytical and quality control purposes.

  • Feedwater Preparation for pure steam generators and clean utilities.
