INSTRUMENTATION & AUTOMATION SYSTEMS

Smart, Reliable, Real-Time Control for Stable Wastewater Treatment Performance

Overview

Instrumentation and automation are critical components of any modern Industrial Effluent Treatment System (IETS). They ensure that the plant runs consistently, responds quickly to load changes, and maintains compliance with DOE standards. Without accurate data and automated control, wastewater plants become vulnerable to sudden failures, fluctuating performance, and costly downtime.


Cheme Advance delivers a complete suite of sensors, controllers, PLC panels, SCADA systems, and IoT monitoring designed for industrial wastewater environments. Our systems enable real-time visibility, early fault detection, and precise control of key treatment processes — reducing manpower requirements and improving operational reliability.


With increasing regulatory expectations, ESG reporting, and the need for stable effluent quality, modern wastewater treatment plants can no longer rely solely on manual monitoring. Automation provides the consistency, precision, and intelligence required to run a high-performing, compliant, and cost-efficient facility.

Industry Challenges This Solves

Plants relying on manual sampling suffer from:



  • Delayed response to issues
  • Limited visibility during off-hours
  • Higher risk of DOE non-compliance
  • Automation solves this with continuous data tracking.

Undetected:



  • pH fluctuations
  • DO drops
  • High turbidity
  • Pump failures


can cause biological upset or process shutdowns.

Many factories face manpower shortages and skill gaps. Automated systems reduce reliance on operator intervention.

DOE audits require clear data trails. Paper logs or inconsistent manual readings can cause compliance issues.

Systems such as MBR, RO, and screw presses require:



  • Precise control
  • Consistent dosing
  • Stable pressure and flow


Automation ensures optimal operation with minimal human error.

Instrumentation and automation directly address these pain points.

What Instrumentation & Automation Systems Do

Instrumentation Measures:

  • pH
  • Dissolved Oxygen (DO)
  • Oxidation Reduction Potential (ORP)
  • Turbidity
  • Total Suspended Solids (TSS)
  • Level and flow
  • Pressure and temperature

Automation Controls:

  • Blowers
  • Pumps
  • Chemical dosing
  • Sludge handling equipment
  • Membrane systems
  • Valves and mixers

In simple terms: Instrumentation tells you what’s happening. Automation responds automatically.

How These Systems Work Step by Step

1. Sensors Collect Real-Time Data

Continuous readings of DO, pH, ORP, turbidity, flow, and other variables.

2. Data Is Sent to PLC/SCADA

Programmable Logic Controllers make decisions instantly.

3. Automated Adjustments Occur

Systems adjust blower speed, dosing rates, pumping cycles, and more.

4. Alarms Trigger When Thresholds Are Exceeded

Operators are notified through panels, SMS, or IoT alerts.

5. Data Logging Ensures Traceability

Every reading is time-stamped for compliance and diagnostics.

6. Remote Monitoring via IoT (ALBE 24/7)

Plant managers can view real-time data anywhere.

This creates a fully controlled treatment environment.
