Sampling Air Limbah (IPAL Domestik)

Summary

The video focuses on the process of collecting domestic wastewater samples in Lampung province, Indonesia, at a laboratory for environmental health. It details the careful preparation, including selecting sampling points, checking water parameters like pH and temperature, and ensuring cleanliness of equipment. The sampling process involves handling the wastewater with caution, using preservatives like sulfuric acid for oil and fat parameters, and storing samples with ice for microbiological analysis. The procedure highlights the importance of accurate and contaminant-free sampling for environmental analysis.

Takeaways

• 😀 The sample collection process begins with preparing equipment and determining the collection location for domestic wastewater.
• 😀 The sampling is carried out at a wastewater laboratory in Lampung, Indonesia, specifically at the UPTD Environmental Laboratory.
• 😀 Before collecting samples, the water flow and sample collection point are assessed to ensure proper sampling procedures.
• 😀 Blank sample containers are prepared to ensure there is no contamination, with careful attention to cleanliness.
• 😀 The physical parameters of the wastewater, including pH and temperature, are tested during the sampling process.
• 😀 The recorded pH level is normal at 6.39, and the temperature is 25°C, both of which are logged in the sample documentation.
• 😀 Special care is taken to avoid air bubbles in the sample containers, as they could affect the results of the analysis.
• 😀 After collection, the wastewater is carefully placed in clean containers, which are thoroughly rinsed before use to ensure no contaminants remain.
• 😀 For the preservation of samples related to oil and grease, sulfuric acid (H2SO4) is added as a preservative.
• 😀 The collected samples are placed in an insulated box with ice to maintain proper temperature until further analysis.
• 😀 All the samples are properly sealed and prepared for transportation to the laboratory for further testing, ensuring they remain uncontaminated.

Q & A

What is the purpose of the sample collection in the script?

The purpose of the sample collection is to test and analyze domestic wastewater, specifically in the UPTD Environmental Laboratory in Lampung Province.

How is the sample collection process initiated?

The process begins by determining the sampling location, followed by preparing the sampling tools and ensuring the cleanliness of the containers.

What physical parameters are tested in the wastewater sample?

The physical parameters tested are pH and temperature. The pH is recorded as 6.39, and the temperature is 25°C.

What is the significance of using a blank sample in the process?

A blank sample is used to ensure that the equipment and containers are free from contaminants that could affect the test results.

Why is it important to avoid air bubbles in the sample container?

Air bubbles are avoided because they can interfere with the accuracy of the test results, especially for certain parameters like oil and grease content.

What preservative is used for oil and grease parameters?

Sulfuric acid (H2SO4) is used as a preservative to maintain the integrity of the sample for oil and grease analysis.

How are microbiological parameters handled in the sample collection?

For microbiological parameters, appropriate preservatives and handling procedures are followed, though specifics are not detailed in the script.

What happens to the sample after it is collected and preserved?

After preservation, the sample is placed in a cooler box with ice to maintain its stability and prevent degradation before testing.

What steps are taken to ensure the cleanliness of the sampling containers?

The containers are rinsed three times to remove any potential contaminants before use in the sample collection process.

What is the ultimate goal of the sample collection process?

The ultimate goal is to ensure that the wastewater samples are properly collected, preserved, and ready for accurate analysis of various environmental parameters.
