Risk Assessment for Purified Water System

PW Generation system 

The fully Automatic PLC based purified water Generation system shall generate Purified water as Per current USP.

The scheme of purified water generation system is as follows:        

• Pre treatment:
• NaOCl dosing system
• Raw Water Storage tank
• Raw Water Pump
• Multi Graded Filter
• Softener Unit
• Ultra Filtration
• UV Light
• UF Water Storage tank
• pH Correction Dosing system
• Antiscalant Dosing System
• SMBS Dosing Tank
• 5 µm Micron Cartridge Filter
• pH meter
• ORP Analyzer along with auto-dumping valve
• PW Generation System:
• RO High Pressure Pump
• Industrial RO with housing
• Conductivity Meter with alarm
• RO + EDI unit
• Conductivity Meter with alarm
• Purified Water storage & Distribution system

• Purified Water Storage Tank
• Purified Water Transfer Pump
• TOC Analyzer
• Ultra Violet Lamp
• User Points
• Flow transmitter in supply & return line
• Temperature sensor in supply & return line
• Conductivity meter with auto-dumping facility

Storage tank

The size of the tank is based on the feed flow rate of the PW generation plant and the peak load of the user points. PW storage tank assembly consists of following components.

• Vertical Storage tank of SS316L, Internally electro polished.
• Level sensor ( Magnetic type)
• Vent filter with electrically heated SS housing & temp. Indicator
• Spray balls
• Tank Drain Valve
• Sanitary Diaphragm Valves
• Compound pressure gauge
