The Laboratory Pure Water System BKSROEZ series delivers high-purity water for laboratory applications requiring low conductivity water. This reverse osmosis system processes city tap water through multiple purification stages to achieve purified water with conductivity ≤0.01ms/m and ion removal rate ≥99%. The system accommodates various laboratory scales with capacities ranging from 300L/H to 1000L/H, operating with standard municipal water supplies within specified temperature and pressure parameters.
The system produces water meeting stringent purity specifications including low absorbance at 254nm (≤0.001) and minimal soluble silicon content (≤0.01mg/L as silica). These specifications support analytical chemistry procedures, equipment rinsing protocols, and buffer preparation where trace contaminants could interfere with experimental results. The system operates on AC380V power supply and functions within ambient temperatures from 2-45°C.
How It Works
The system employs reverse osmosis membrane technology to remove dissolved ions, organic compounds, and particulate matter from municipal water supplies. Feed water passes through multiple filtration stages where applied pressure forces water molecules through semi-permeable membranes while rejecting larger contaminants. The reverse osmosis process physically separates ions and molecules based on size exclusion, achieving the specified ≥99% ion removal rate.
Pre-filtration stages remove chlorine and particulates that could damage the RO membranes, while the membrane assembly provides the primary purification step. The system monitors conductivity continuously to verify water quality, with the final product meeting specifications for conductivity (≤0.01ms/m), UV absorbance (≤0.001 at 254nm), and soluble silicon content (≤0.01mg/L). Temperature and pressure controls maintain optimal operating conditions for consistent performance across the specified ambient temperature range of 2-45°C.

Practical Tips
Replace pre-filtration cartridges when pressure differential exceeds manufacturer specifications or every 6-12 months.
Why: Clogged pre-filters reduce system efficiency and can damage downstream RO membranes.
Calibrate conductivity meters monthly using certified standard solutions to ensure accurate water quality monitoring.
Why: Accurate conductivity measurement is critical for verifying product water meets purity specifications.
Flush the system for 10-15 minutes after extended shutdown periods before collecting water for analytical use.
Why: Initial flush removes stagnant water and ensures product quality meets specifications.
Log daily conductivity readings and flow rates to track system performance trends over time.
Why: Performance trending identifies gradual membrane degradation before product quality is compromised.
If conductivity increases above specification, check membrane integrity and verify adequate feed water pressure.
Why: Rising conductivity indicates membrane damage or insufficient operating pressure affecting separation efficiency.
Install appropriate electrical protection for the AC380V power supply and ensure proper grounding.
Why: High-voltage electrical systems require proper safety measures to prevent electrical hazards during operation and maintenance.
