Description
Strong Scale Remover Solution with Controlled Corrosion without the Need to Stop the System
Corrosion of the Sard Mitreh of 10-20 mpy is very low compared to the existing descaler types that have corrosion of 70-980 mpy, this property makes it easier for the Mitreh to circulate with the water fluid in the installation, and to scale removing all parts of the installation.
Advantages of Sard Solution:
- High power
- Complete system deposition
- Controlled corrosion compared to descaler
- No need to stop in system
- Environmental friendly
- Applicable to a wide range of scale and corrosion products
- Accelerate the process deposition compared to industrial Mitreh
- Safe replacement rather than acid wash
- No harmful skin and respiratory effects
Usage:
After calculating the amount of scale in the entire closed-circuit system desired by the facility technical experts, Depending on the type of scale estimated for each kilogram of scale, approximately 2 to 3 kg of general Sard Mitreh solution is considered.
Use the desired amount of solution with the following procedure:
- First, add the calculated solution to the system water and circulate for 15 minutes then allow the solution to stand for 2 to 3 hours to soak the scale and then remain stationary.
- After the elapsed time, circulate the system fluid with the pump and repeat the circulation for 30 to 40 minutes. Then allow the solution to stationary in the system for 1 to 2 hours again.
- The pumps should be turned on again and the fluid recirculated and water and scales completely discharged after 40 to 50 minutes.
- After the above steps, rinse the system thoroughly twice and drain the remaining water and scale completely.
- After the above operation, in the case of scale in the system with one-second to one-third the initial amount (depending on the amount of scale remaining), repeat the above steps and complete the drainage system water.
- After thoroughly washing the circuit, dehydrate the system with light water (R.O or DM water or …) and inject for primary improvement, and control and maintenance.
Essentials during the Deposition Operation:
- Take a sample of the solution and measure the pH and TH factors at each step in the water.
- If it stays second; pH rises to 5; Cancel the next steps and circulate water for one hour and then drain.
- Sampling of water in the system prior to injection of the scale removing solution and during discharge is also necessary.
