Arro-Cleaning encompasses a variety of techniques designed to effectively remove fouling from membrane surfaces and restore optimal performance. These techniques often involve a combination of chemical cleaning agents, specialized equipment, and optimized cleaning protocols.

Key Techniques:

• Chemical Cleaning: This is the most common technique, utilizing a range of specialized cleaning chemicals to target specific types of fouling. These chemicals break down organic matter, scale, inorganic deposits, and other contaminants, leaving the membrane surface clean and ready for operation.
• Backwashing: This technique involves reversing the flow of water through the membrane module, physically dislodging loosely attached debris and contaminants. Backwashing is often employed as a preliminary step before chemical cleaning to maximize its effectiveness.
• Air Scouring: This technique involves introducing compressed air into the membrane module, dislodging fouling by creating turbulence and mechanical force. Air scouring is particularly effective for removing soft organic deposits.
• Ultrasonic Cleaning: This technique utilizes high-frequency sound waves to generate cavitation bubbles that break down fouling and dislodge it from the membrane surface. Ultrasonic cleaning is effective for removing tightly bound fouling.
• Electrochemical Cleaning: This technique utilizes an electric current to generate chemical reactions that dissolve or dislodge fouling from the membrane surface. Electrochemical cleaning is particularly effective for removing metal oxides and scaling.
