Tata Cara Pengambilan Sampel Air Limbah/IPAL untuk Pemeriksaan Kimia. #kesling #sanitarian

Summary

This video provides an informative guide on how to properly collect water samples for chemical analysis in wastewater treatment facilities (IPAL). It outlines the essential steps, starting with the use of gloves and observing the physical characteristics of the water such as odor and color. The process includes using a digital pH meter to check the water's acidity or alkalinity, and carefully rinsing the sample bottle to avoid contamination. The final steps involve labeling the bottle with necessary information, including sample details and the date. The video also touches upon the importance of maintaining and cleaning the wastewater system after sample collection.

Takeaways

• 😀 Wear gloves before collecting water samples to maintain safety and cleanliness.
• 😀 Inspect the physical characteristics of the water, such as odor and color, before sampling.
• 😀 Measure the water's pH level using a digital water dispenser to assess its acidity or alkalinity.
• 😀 Prepare a clean bottle for the water sample collection.
• 😀 Perform surface water skimming by filling and discarding water in the bottle 2-3 times to remove debris and foam.
• 😀 After cleaning the bottle, proceed to collect the water sample carefully from below the surface.
• 😀 Ensure the bottle is tightly closed after collecting the sample to prevent contamination.
• 😀 Clean the exterior of the bottle with a tissue or cloth to maintain hygiene.
• 😀 Label the water sample bottle with important information like the owner's name, contact number, sample type, test type, and sampling details.
• 😀 After sample collection, clean the wastewater treatment system by draining it (pengurasan).

Q & A

What is the initial condition of the wastewater treatment plant (IPAL) before cleaning?

The initial condition of the wastewater treatment plant (IPAL) is as it is, before any cleaning or draining process is done.

What is the first step in the water sampling procedure for chemical testing?

The first step is to wear hand gloves before conducting the water sampling to maintain safety and hygiene.

How is the physical quality of the water checked before taking a sample?

The physical quality of the water is observed by checking its odor, color, and appearance. Additionally, the pH level is tested using a digital pH water meter.

What does the process of 'tebas tebas' mean in the context of water sampling?

The 'tebas tebas' process refers to briefly rinsing the bottle with a small amount of water from the sample to prevent contamination from surface dirt or foam that may affect the test results.

How many times should the surface of the water be rinsed with the bottle during the sampling process?

The surface of the water should be rinsed with the bottle two to three times before the actual sample is taken.

Why is the surface of the water rinsed before taking a sample?

Rinsing the surface helps prevent the inclusion of dirt or foam from the water's surface, which could impact the accuracy of the test results.

What is done after the water sample is taken in the process?

After the sample is taken, the bottle is closed, and its exterior is wiped clean with a tissue or cloth to avoid contamination.

What information should be included on the label of the water sample bottle?

The label should include the name of the owner or operator, phone number, type of sample, type of test, location or address, date and time of sampling, the name of the person who took the sample, and the institution handling the sample.

What happens after the water sample is collected for chemical and microbiological testing?

After the sample is collected, the water treatment plant undergoes maintenance through a draining process to ensure the system is clean and functional.

What is the final message conveyed at the end of the script?

The final message is a thank you and a hope that the information provided is beneficial, along with a playful sign-off.
