What are the different applications where chemical injection is applied?
Applications that require chemical injection pumps are multiple. Given the importance of these pumps in the efficiency of the operational process, we explain some of the common challenges and their solutions.
Chemical injection is used in a wide range of applications including:
- Drinking water treatment: to disinfect, oxidize organic matter and remove suspended particles.
- Industrial process water: to help control wastewater discharge, prevent sedimentation and corrosion.
- Wastewater treatment: to remove contaminants, purify wastewater and ensure discharge standards are met.
- Swimming pools and spas: to maintain water quality and prevent bacterial growth.
Common Chemicals Injected with Chemical Injection Pumps
| Chemical | Purpose | Range | |
| From | To | ||
| Chlorine | Disinfection, oxidation of organic matter | 0.1 | 5 mg/L |
| Ferric sulfate | Water purification, coagulation of particles | 2 | 20 mg/L |
| Aluminum chloride | Coagulation, agglomeration, removal of suspended particles | 1 | 10 mg/L |
| Sodium hypochlorite | Water disinfection | 0.2 | 5 mg/L |
| Ozone Oxidation | disinfection, deodorization, organic matter | 0.1 | 1 mg/L |
| Chlorates | Removal of heavy metal ions and organic pollutants | 2 | 10 mg/L |
| Potassium permanganate | Oxidation of organic matter, deodorization | 1 | 5 mg/L |
| Ammonia inhibitors | Prevent chloramine formation | 1 | 5 mg/L |
| Anti-scaling agents | Prevent scale and deposits | 2 | 20 mg/L |
Chemical Injection Challenges and Solutions
Problem: The metering pump is not working properly, The material cannot be accurately injected.
Solution: Check the power supply, connection line and control system of the metering pump to ensure that it works normally. Check whether the pump parts are worn or blocked, and replace or clean them in time.
Problem: The chemical leaks or leaks.
Solution: Check the tightness of the injection tube and connections to ensure that there are no leaks. Install leak detection and emergency shutdown devices to prevent the spread of leaks.
Problem: Uneven mixing of chemicals, resulting in inaccurate dosage.
Solution: Use appropriate mixing equipment, such as motors or mixing tanks, to ensure that the chemicals are well mixed. Regularly check the operating condition of the mixing equipment to avoid blockage or failure.
Problem: The chemical reaction of chemicals affects the injection effect.
Solution: Conduct laboratory tests before injection to understand the reaction between chemicals and water. Adjust the type and dosage of chemicals to avoid unnecessary chemical reactions.
Problem: Blockage or accumulation of injection equipment.
Solution: Regular cleaning and maintenance of injection equipment, tubing and mixing equipment to avoid residue and accumulation of chemicals. Use appropriate chemical cleaning agent for regular cleaning.
Problem: Environmental factors such as temperature, pressure, etc. affect the performance of the chemical.
Solution: Conduct an environmental test of the chemical’s performance to see how it behaves under different conditions. Adjust the injection equipment and operating parameters according to the actual situation.
Problem: Control system failure, inability to accurately control the injection of chemicals.
Solution: Check the power supply, sensors, and control system software to ensure they are working properly. Maintain the control system regularly and repair or replace defective parts in a timely manner.
