Trial operation of waste treatment works
After the Environmental Permit is issued, many projects must run their waste treatment works on a trial basis before official operation. Nanoen prepares the plan, coordinates sampling with a qualified monitoring unit, follows the system on site and prepares the results report under current regulations.
- Clear trial operation plan
- Coordination with a qualified monitoring unit
- On-site monitoring and system adjustment
- Results report on the current template

Common challenges for businesses
If you are facing any of the situations below, Nanoen can help.
Unclear steps after the permit
The project owner is unsure which trial operation, notification and reporting steps are required.
Unsuitable sampling plan
Sampling points, frequency or parameters do not match the Environmental Permit.
System not yet stable
The new treatment works has just started up and treated wastewater or exhaust gas does not yet meet national technical regulations (QCVN).
Failed samples mean repeats
Non-compliant monitoring results prolong the trial operation and add cost.

Frequently asked questions
Which projects must carry out trial operation of waste treatment works?
Under the Law on Environmental Protection 2020, Decree 08/2022/ND-CP, Circular 02/2022/TT-BTNMT and their amending documents, investment projects granted an Environmental Permit with waste treatment works are generally required to carry out trial operation, except in certain exempt cases. Nanoen reviews the permit and current regulations to confirm each project's specific obligations.
How long does trial operation last?
It depends on the type and capacity of the works and on what the Environmental Permit states under current regulations. Nanoen proposes a specific timeline after reviewing the permit and the system.
What happens if monitoring results do not meet the standards?
Nanoen identifies the cause, adjusts operation or proposes upgrades to the works, then arranges re-sampling. Following the system closely from the start helps avoid extending the trial period.
Does Nanoen carry out sampling and analysis itself?
Sampling and analysis are carried out by a monitoring unit qualified under regulations. Nanoen helps plan and supervise sampling and compiles the results into the report.
