WETEC

Industrial Water Quality Monitoring System

Continuous online monitoring of process water, utility water and trade effluent for industry.

Overview

Water quality sits at the center of industrial operations, from ultrapure rinse water in wafer fabs to cooling tower water in data centers and the final effluent leaving the last inspection chamber. Trade effluent discharged into public sewers must meet authority's Sewerage and Drainage (Trade Effluent) Regulations at all times, and discharge into watercourses is held to even tighter limits. Grab samples and laboratory results arrive days later, long after an excursion has already happened. Wetec designs and supply industrial water quality monitoring systems, engineered around your process, your discharge permit and your plant layout.

What You Can Measure

Several measurements can share one controller, and the system grows as your plant does.

pH | ORP | Conductivity | Resistivity | ppb DO | Optical DO | Galvanic DO | Turbidity | Suspended Solids | TDS | Free Chlorine | Total Chlorine | Chlorine Dioxide | Ammonium | Bromide | Cadmium | Calcium | Chloride| Copper | Cyanide | Fluoride | Lead | Nitrate | Nitrite | Potassium | Silver | Sodium | Sulfide | Aluminum | Ammonia | Chlorine | Chloride | Chromium VI | Hardness | Iron | Manganese | Nickel | Nitrate | Nitrite | Phosphate | Total Phosphate | Silica | Sulfate | Zinc | Alkalinity | Oil in Water | BOD | COD | TOC

Typical Monitoring Points

  • Incoming water: town water, NEWater or industrial water quality before it enters your process

  • Process and utility water: ultrapure water, boiler feedwater, cooling towers and rinse lines

  • Treatment plant: neutralisation, biological treatment, clarification and polishing stages

  • Final discharge: the last inspection chamber or outfall, where compliance is judged

Applications

  • Trade effluent compliance at the last inspection chamber

  • Wastewater pretreatment and pH neutralisation plants

  • Semiconductor and electronics: ultrapure water, fluoride and acid waste

  • Pharmaceutical and biomedical manufacturing

  • Petrochemical and chemical plants on Jurong Island

  • Power, cogeneration and boiler water

  • Cooling towers in data centres and commercial buildings

  • Food and beverage processing

  • Metal finishing, plating and PCB manufacturing

  • Water reclamation, NEWater and industrial water reuse

Frequently Asked Questions

Industries that generate large volumes of acidic and metals effluent must install pH and heavy metals monitoring with an automatic shut-off to keep non-compliant effluent out of public sewers. Other monitoring requirements depend on the conditions in your PUB Written Approval or NEA permit. Wetec can review your permit and recommend the right parameters.
