Deep well sampling is a challenging task. General groundwater samplers can easily cause volatile loss and cross interference, resulting in distorted sample data. The AIMOLI AML919 Groundwater Sampler ensures no volatile loss and no cross interference throughout the entire process. It has been used as an enforcement instrument by the National Analysis and Testing Center of the Ministry of Ecology and Environment, as well as relevant departments in 28 provinces and cities.
Engineer Wang from an environmental monitoring company in Hebei recently encountered a difficult problem. His company had undertaken a groundwater sampling project for a chemical industrial park.
Originally, this was a good opportunity. However, the depth of the wells in this chemical industrial park reached 120 meters, and the groundwater sampler they previously used was a traditional combination of a bailer and submersible pump. Therefore, they conducted continuous sampling on several wells, but the data results were very poor and had no reference value at all.
In order to successfully complete the project and upgrade their equipment, Engineer Wang contacted several domestic groundwater sampler manufacturers and distributors of imported groundwater samplers.
However, among the domestic manufacturers he contacted, some used ordinary submersible pumps. During pumping, air bubbles could easily enter the sample, causing data distortion.
Some manufacturers used low-flow submersible pumps to reduce volatilization. Although this was effective for ordinary wells, deep wells have higher static water pressure, and when water passes through long pipelines for lifting, volatilization is still serious.
Some domestic manufacturers used bladder pumps for groundwater sampling, but their designed lifting capacity was insufficient. Meanwhile, imported groundwater samplers were too expensive, far exceeding Engineer Wang’s budget.
Therefore, Engineer Wang contacted AIMOLI. The AIMOLI AML919 Groundwater Sampling System mainly has 3 major advantages:
- Data reliability. Traditional submersible pump groundwater samplers may cause volatilization during sampling. The AIMOLI bladder pump groundwater sampler has no volatile loss and no cross interference throughout the entire sampling process, making the data more reliable.
- Reliable performance. Compared with the measurement range of domestic bladder pump groundwater samplers, the standard configuration of the AIMOLI AML919 Groundwater Sampler supports 70 meters, and there are users applying it at 300-meter depths without failures.
- Sampling efficiency. Compared with imported groundwater samplers, the AIMOLI Groundwater Sampler produces water output in an average of 3 minutes, which is sufficient to match or exceed imported equipment. The sampling quality of a bladder pump combined with the efficiency of a submersible pump has been highly recognized by industry peers.
At the same time, traditional on-site sampling requires carrying one water level meter, one well depth meter, and one drawdown meter. In addition, these three instruments need to be lowered into the well separately.
The AIMOLI AML913 Groundwater Three-Water-Level Instrument has overcome multiple technical challenges and integrates three instruments into one. It reduces the number of instruments required for field operations. With only one probe and one well deployment, it can detect 3 types of data, greatly improving detection efficiency. Currently, no other company in China can achieve this.
Furthermore, the AML913 Three-Water-Level Instrument can work together with our AIMOLI AML919 Groundwater Sampler. During groundwater well purging and sampling, the AIMOLI AML919 Groundwater Sampler automatically controls the process according to the drawdown data provided by the AML913 Three-Water-Level Instrument. This process requires no manual intervention, reduces data distortion caused by human operation, and complies with national standard requirements.
To verify the reliability of the data, Engineer Wang invited the AIMOLI team to conduct a groundwater sampling demonstration on-site last week. The sampling results fully met the standards.
Therefore, Engineer Wang’s company purchased our AIMOLI AML919 Groundwater Sampler. Ultimately, because the sampling data was accurate and reliable and the project was completed ahead of schedule, the client was very satisfied and decided to assign another project to Engineer Wang’s company.
AIMOLI Environmental Instruments, the precise solution that the industry urgently needs!
