DRE Testing in Malaysia

Destruction and Removal Efficiency (DRE) Testing Services

FESLAB SDN BHD provides Destruction and Removal Efficiency (DRE) Testing services throughout Malaysia for industrial facilities requiring performance evaluation of applicable Air Pollution Control Systems (APCS) and emission control equipment.

DRE Testing is used to determine the effectiveness of an emission control system in destroying or removing a targeted air pollutant from an industrial exhaust stream.

FESLAB provides professional environmental monitoring and testing services to support industries in evaluating the performance of their air pollution control systems and meeting applicable Department of Environment (DOE/Jabatan Alam Sekitar – JAS) Malaysia requirements.

What is DRE Testing?

DRE stands for Destruction and Removal Efficiency.

DRE Testing evaluates the efficiency of an air pollution control system by comparing the concentration or mass flow of a targeted pollutant before and after the control system, where applicable.

In simplified terms:

DRE (%) = [(Inlet − Outlet) / Inlet] × 100

A higher DRE percentage generally indicates greater destruction or removal of the targeted pollutant by the control system.

The appropriate sampling method, calculation basis and acceptance criteria depend on the pollutant, process, control system and applicable regulatory or technical requirements.

Why is DRE Testing Important?

DRE Testing can provide quantitative evidence of the performance of an installed air pollution control system.

Testing may help industrial facilities:

Evaluate APCS performance
Determine pollutant removal efficiency
Verify system operating effectiveness
Identify deterioration in control performance
Support optimisation of pollution control equipment
Provide technical data for environmental compliance purposes
Support DOE/JAS documentation where applicable

Air Pollution Control Systems

DRE Testing may be applicable to various emission control technologies depending on the pollutant and industrial process, including:

Wet scrubbers
Dry scrubbers
Packed-bed scrubbers
Activated carbon systems
Thermal oxidisers
Incineration systems
Other applicable air pollution control equipment

The suitability of DRE Testing should be evaluated according to the specific process, pollutant and control system.

DRE Testing Methodology

Depending on the applicable system, a DRE assessment may involve measurements at both the inlet and outlet of the Air Pollution Control System.

The general process may include:

Review of the industrial process and APCS.
Identification of the targeted pollutant.
Identification of suitable inlet and outlet sampling locations.
Measurement or sampling of the pollutant before treatment.
Measurement or sampling after treatment.
Laboratory analysis, where required.
Calculation of Destruction and Removal Efficiency.
Evaluation of results.
Preparation of a technical testing report.

Testing methodology will depend on the specific pollutant and applicable sampling or analytical method.

Industries That May Require DRE Testing

DRE Testing may be relevant to:

Chemical manufacturing
Petrochemical industries
Pharmaceutical manufacturing
Waste treatment facilities
Scheduled waste facilities
Metal processing industries
Surface coating operations
Solvent-using processes
Industrial combustion processes
Manufacturing facilities with scrubbers
Facilities using thermal oxidation
Other industries operating air pollution control systems

DRE Testing & Stack Emission Monitoring

FESLAB can coordinate DRE Testing together with Stack Emission Monitoring, where applicable.

Combining these services can provide a more comprehensive assessment of the emission source and the performance of the associated Air Pollution Control System.
