I.Overview
PLC (Programmable Logic Controller) serves as the control hub and intelligent decision-making core in ultra-pure water (UPW) systems. Through real-time data acquisition, multi-variable coordinated control, and fault diagnosis, it ensures water quality consistently meets the semiconductor-grade standard of 18.2 MΩ·cm. In ultra-pure water systems, PLCs have evolved from basic automation to intelligent decision-making hubs. In advanced processes below 3nm, their control precision (e.g., TOC ±0.05 ppb) directly determines chip yield rates.
II.Process
Raw Water → Raw Water Tank → Booster Pump → Flocculant/Reducer Dosing → Activated Carbon Filter → Ultrafiltration (UF) → Scale Inhibitor Dosing → Security Filter → 1st Stage High-Pressure Pump → 1st Stage RO → pH Adjustment → Intermediate Tank → 2nd Stage High-Pressure Pump → 2nd Stage RO → Purified Water Tank → EDI Booster Pump → UV Sterilizer → Cartridge Filter → EDI System → Ultra-Pure Water Tank → Transfer Pump → TOC Removal Unit → Polishing Resin → Final Filter → Point of Use
III.Core application scenarios of PLC
| Full - process Technology Automation | ||||||
| Process Segment | PLC Control Function | |||||
| Pretreatment | Sequential control of backwashing of sand - carbon filter (triggered by both pressure difference/time), precise dosing of dosing pump (scale inhibitor/NaClO) | |||||
| RO Membrane System | Frequency control of high - pressure pump (maintaining constant product water flux), adjustment of concentrate valve opening (recovery rate 75% - 85%) | |||||
| EDI Module | Adaptive adjustment of DC voltage (0 - 600V), switching of limiting current mode (preventing polarization) | |||||
| Mixed - bed Polishing | Judgment of resin failure (resistivity drop > 0.5 MΩ·cm), fully automatic cycle of acid - base regeneration (flow/concentration closed - loop) | |||||
| Closed - loop Control of Water Quality Parameters | ||||||
| Parameter | Control Strategy | |||||
| Resistivity | PID algorithm dynamically adjusts the inlet flow of mixed - bed (set value 18.18 MΩ·cm, response time < 5s) | |||||
| TOC | UV - ozone unit interlock control (increase ozone concentration by 10% - 30% when TOC> 0.3 ppb) | |||||
| Dissolved Oxygen (DO) | Vacuum degree adjustment of membrane degassing system (target DO < 3 ppb) | |||||
| System Safety Interlock Protection | ||||||
| Risk Type | PLC Response Mechanism | |||||
| High Pressure of RO Membrane | Emergency shutdown of pump + opening of pressure relief valve when pressure > 1.5 MPa | |||||
| UPW Microbial Contamination | Trigger ozone shock disinfection (0.1 ppm×2h) when bacteria > 0.01 CFU/mL | |||||
| Water Tank Liquid Level | Lack - of - liquid - level interlock to stop pump (prevent idling), close inlet valve at high liquid level (prevent overflow) | |||||
IV.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
