Laboratory Service

Laboratory measurement of environmental parameters in the paper industry and Effluent Treatment is critically important because paper manufacturing is resource-intensive and generates significant environmental impacts.
Careful monitoring through lab testing ensures compliance, efficiency, and sustainability.

Meri provides the experienced Laboratory Services securing the following advantages:

1. Regulatory Compliance

  • Paper mills discharge large volumes of wastewater, emit air pollutants (SO₂, NOₓ, particulates), and generate solid waste.
  • Environmental agencies require industries to meet standards for effluent quality, stack emissions, and waste disposal.
  • Laboratory measurement of parameters like BOD, COD, TSS, pH, heavy metals, SO₂, NOₓ, and particulate matter ensures operations meet legal discharge and emission limits.

2. Pollution Control

  • Lab testing provides accurate data on pollutants before and after treatment.
  • Parameters such as BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), and TSS (Total Suspended Solids) indicate the efficiency of effluent treatment plants (ETPs).
  • Monitoring air parameters like particulate matter and gaseous pollutants ensures air pollution control equipment (electrostatic precipitators, scrubbers) is working effectively.

3. Resource Optimization

  • Water, energy, and chemicals (chlorine, bleaching agents, alkalis) are heavily used in paper production.
  • Measuring pH, conductivity, and chemical residues helps optimize chemical dosing, reduce wastage, and cut costs.
  • Monitoring water hardness, temperature, and flow improves process efficiency.

4. Worker & Community Health

  • Laboratory measurement of air quality (dust, SO₂, chlorine, etc.) ensures workplace safety and minimizes exposure risks.
  • Noise levels and odorous emissions can also be monitored for worker and community well-being.

5. Sustainability & Environmental Responsibility

  • The paper industry is often criticized for its ecological footprint.
  • Regular lab analysis supports ISO 14001 Environmental Management Systems and sustainability reporting.
  • Monitoring helps industries adopt cleaner production practices (e.g., elemental chlorine-free bleaching, water recycling).

6. Early Problem Detection

  • Continuous lab measurement helps detect changes in process water quality, untreated effluents, or rising pollutant loads.
  • This enables preventive action before issues escalate into violations, equipment failures, or community complaints
