P-BP1000 Groundwater Low Speed Sampling and Well Cleaning Analysis System

P-BP1000Groundwater low-speed sampling and well washing analysis systemProduct Introduction

Low speed sampling is a method of extracting groundwater samples from a well at a low flow rate, where the flow rate is controlled within a certain range 100-500mL/min， The water level drop should not exceed 10cm, which can minimize the volatilization of pollutants and the amount of wastewater generated. Geotech on-site low-speed sampling system and VuSitu ™ Mobile applications minimize errors, save time, and improve low flow sampling efficiencycostAnd it can generate reliable reports.

The low-speed sampling and well washing analysis system for groundwater should be developed by Geotech low-speed sampling equipment (airbag pump)，Multi parameter analysis equipment (including low-speed sampling analysis software)andWater level drop control equipmentComposition, this system can be used in VuSitu ™ Under the guidance of software, complete low-speed well flushing work and select appropriate sampling timing. While sampling, multi parameter analysis equipment can perform real-time routine parameter analysis on the collected samples to obtain reliable water quality data.

Low speed well flushing and sampling of groundwater is different from traditional well flushing and sampling. Low speed well flushing and sampling is a new method that does not require extracting a large amount of water from the well. Groundwater with low flow rate (flow rate controlled within) 100-500mL/min， Pump water from the well screen (with a water level drop not exceeding 10cm), and only extract the sampling area rather than the entire well volume. This method minimizes the disturbance of water and the impact on the well and surrounding strata during the well washing and sampling process, reducing the sample's impactturbidity.

Compared with traditional methods, low-speed well flushing and sampling methods for groundwater have the following advantages:

Improving sample quality through low-speed well washing and sampling methods can reduce turbidity and minimize volatilization. Because turbidity no longer interferes with the determination of physical and chemical indicators, there is no need for sample filtration steps, further reducing sampling and analysis costs.

Improve sample accuracy and precision, enabling users to accurately determine the true trend of geochemistry, avoiding unnecessary costs of supervision and repeated sampling to prevent sample contamination.

A simpler and cheaper sampling system, which is more economical and convenient compared to traditional well flushing and sampling with high flow rates.

Extending the service life of a well by reducing sediment flow into the well through low flow rates, prolonging the service life of the well, and reducing the need for well maintenance.

Low speed groundwater flushing and sampling equipment

Geotech airbag pump, is a low flow rate, low disturbance groundwater flushing and sampling equipment, suitable for various types, especiallyVOC Collection of class pollutant samples.

The airbag pump controller is equipped with a small air compressor that provides compressed air to meet the needs ofStill water levelWithin 60 metersRequirements for operating conditions. If the water level is deep，A booster controller can be installed to enable the airbag pump to operate at depths of up to Sampling is conducted below a liquid level of 300 meters. To achieve a deeper sampling depth, the airbag pump can also be equipped with a drop pipe component to allow deeper groundwater samples to enter the airbag pump. In order to ensure low disturbance to groundwater, the airbag pump can also choose a drop probe. When the groundwater level settles too much during the sampling process, the sampling can be automatically stopped and wait for the water level to recover.
