1. Product Introduction
Reverse osmosis purification water system for pharmaceutical preparation is customized sanitary purified water preparation equipment developed to meet strict water quality standards of pharmaceutical preparation industry. Purified water is the basic raw material for oral liquid, injection, ointment, syrup and other pharmaceutical preparations. Raw tap water or underground water contains calcium-magnesium hardness, colloids, trace heavy metals, microbial spores and endotoxin precursors. If unprocessed water is directly used in pharmaceutical production, it will cause drug instability, increased particulate matter in preparations, microbial overgrowth and hidden safety hazards of finished medicines. Therefore, stable, continuously monitored purified water supply system is mandatory supporting facility for GMP-standard pharmaceutical workshops.
The whole system adopts modular skid-mounted sanitary design. All pipelines and pressure vessels in contact with water adopt pharmaceutical-grade stainless steel, optimized low dead-angle structure to prevent microbial adhesion and reproduction, fully matching pharmaceutical GMP workshop requirements. The front pretreatment unit is equipped with high-performance liquid filter to intercept sediment, particulate impurities and colloids, protecting subsequent RO membrane elements from irreversible organic and biological fouling.
Enterprises can select specifications according to daily water consumption: small pharmaceutical R&D and pilot workshops adopt small integrated RO units; medium-sized pharmaceutical preparation factories choose 5 tons/hour reverse osmosis equipment and 10 tons/hour reverse osmosis system; large pharmaceutical industrial parks can connect multiple units in parallel to build 100 tons/hour reverse osmosis system. For high-standard water for injection projects, two-stage reverse osmosis combined with EDI module can be configured to further improve water purity.
Many pharmaceutical technical managers compare this RO purification water system with traditional ion exchange equipment. Single ion exchange needs frequent acid and alkali regeneration, which brings risks of secondary pollution. Reverse osmosis realizes deep physical purification, removing ions, particulate impurities and microorganisms simultaneously. The purified water produced by RO main unit can be directly used for preparation compounding, raw material dilution and equipment CIP cleaning. Concentrated water separated in the process is transported to factory wastewater treatment station for centralized treatment in accordance with environmental protection regulations. Different from ordinary industrial reverse osmosis equipment, reverse osmosis purification water system for pharmaceutical preparation focuses on sanitary pipeline layout, online disinfection function, complete data recording and traceability, and has become standard matching equipment for newly built and renovated pharmaceutical preparation production lines.
2. Working Principle of Reverse Osmosis Purification Water System For Pharmaceutical Preparation
Reverse osmosis adopts pressure-driven physical membrane separation technology. Under external driving pressure higher than natural osmotic pressure of raw water, water molecules pass through semi-permeable pharmaceutical-grade RO membranes. Soluble salts, heavy metal ions, colloids, microbial spores and macromolecular endotoxin precursors are trapped on the concentrated water side, realizing deep purification of raw water without excessive chemical addition.
The complete pharmaceutical factory water treatment workflow is divided into four core stages:
Stage1: Multi-stage precision pretreatment filtration
Raw water sequentially flows through multi-media filter, activated carbon filter and liquid filter. This process removes sediment, residual chlorine and suspended particles, reduces water turbidity and SDI value, and creates stable qualified inflow conditions for RO membrane elements.
Stage2: Dosing adjustment and pressurization
Scale inhibitor and biocide are added quantitatively as required to suppress membrane scaling and microbial breeding. Qualified pretreated water is boosted by sanitary anti-corrosion high-pressure pump to reach the optimal working pressure of pharmaceutical-grade RO membranes.
Stage3: Reverse osmosis deep purification separation
Pressurized raw water enters membrane pressure vessels. RO membranes intercept various pollutants. Water is divided into two streams: low-conductivity purified water for pharmaceutical preparation production and high-salinity concentrated wastewater. Purified water is delivered to each preparation workshop through closed circulating sanitary pipelines.
Stage4: Intelligent monitoring and automatic flushing
PLC control system continuously monitors water conductivity, operating pressure, flow and water tank liquid level. Automatic cross-flow flushing will be activated during shutdown to wash pollutants attached to membrane surfaces. Operators can arrange regular online chemical disinfection to control biofouling risk.
If enterprises need to produce water for injection (WFI), two-stage reverse osmosis plus EDI ultrapure water configuration is recommended to further enhance endotoxin and ion removal efficiency.
