WATER TEST Engine Cooling Water Nitrite, Chloride, ph

Summary

This video script outlines a crucial water quality control process for maintaining engine cooling systems. It details the daily testing of engine cooling water for nitrite and chloride levels, using tablets and a syringe for sampling. The process involves adding tablets until a color change occurs, then calculating the concentration in ppm. Additionally, a pH test is conducted using test strips. The script emphasizes recording results and taking corrective actions if limits are exceeded, ensuring system efficiency and compliance with regulations.

Takeaways

• 🔬 Quality control of water is essential for maintaining a system in top condition.
• 💧 Regular sampling and testing of water is crucial, and it should be done daily.
• 📍 Always take water samples from the same place in the engine cooling water circuit.
• 🚰 Allow the water to flow before sampling to ensure the line is free of sediment.
• 💉 For the nitrite test, take a 5 milliliter water sample and make it up to 50 milliliters with distilled water.
• 🔴 Nitrite is measured in parts per million (ppm) and is calculated by multiplying the number of tablets by 180.
• 🧪 The chloride test involves taking a 50 milliliter water sample and adding tablets until the color changes to permanent orange brown.
• 🟠 Chloride concentration is calculated by multiplying the number of tablets by 20 and subtracting 20.
• 🔍 The pH test for engine cooling water involves using test strips and comparing the color to a scale.
• ⚠️ If test results are out of control limits, Water Proof will provide advice on corrective actions.
• 🛠️ Use a range of water treatment products designed to protect and treat systems, following the instructions on the datasheet.

Q & A

Why is quality control of water essential for maintaining a system?

Quality control of water is essential to ensure the system operates efficiently and to maintain regulatory and OM specifications.

How often should water quality be tested for optimal system maintenance?

Water quality should be tested daily to ensure the system is maintained in top condition.

Where should the engine cooling water sample be taken from?

The engine cooling water sample should be taken from the cooling water circuit, always from the same place to ensure consistency.

What is the purpose of allowing the water to flow before taking a sample?

Allowing the water to flow before taking a sample ensures that the line is free of sediment, providing a more accurate sample.

How much water sample is needed for the nitrite test?

A 5 milliliter water sample is needed for the nitrite test.

How is the nitrite concentration measured in the water sample?

Nitrite concentration is measured in parts per million (ppm) and is calculated by multiplying the number of nitrite number two tablets used by 180.

What color change indicates the presence of nitrite in the water sample?

A persistent pink color in the water sample indicates the presence of nitrite.

How is the chloride concentration determined in the water sample?

Chloride concentration is determined by adding tablets to a 50 milliliter water sample and observing the color change from yellow to permanent orange brown. It is measured in ppm by multiplying the number of tablets added by 20 and then subtracting 20.

What is the purpose of the pH test for engine cooling water?

The pH test is used to determine the acidity or alkalinity of the engine cooling water, which is crucial for system efficiency and protection.

How should the pH of the engine cooling water be measured?

The pH is measured by immersing a test strip in the water sample for one minute, then comparing the color obtained with the color scale on the pH indicator strips.

What actions should be taken if the test results are out of control limits?

If test results are out of control limits, Water Proof will provide advice on corrective actions to bring the water quality back to acceptable levels.

Why is it important to follow the instructions on the product datasheet for water treatment products?

Following the instructions on the product datasheet ensures that the water treatment products are used correctly, maintaining system efficiency and regulatory compliance.
