How to Maintenance and Clean the UF Membrane?

1. Regular Backwash Procedure

Regular backwashing removes contaminants from the membrane surface through reverse water and air flow. This process typically includes the following steps:


UF Membrane Air Scour Step
I. Air Scour Step for Ultrafiltration Membrane

•Air Scour: Introduce oil-free air from the bottom of the membrane module to loosen and remove particles attached to the membrane surface. Air flow rate: 8-12Nm³/h, duration: 20-60 seconds.

UF Membrane Gravity Drain Step
II. Gravity Drain for Ultrafiltration Membrane

•Gravity Drain: Use gravity to remove loosened contaminants.

UF Membrane Backwash Top Step
III. Top Backwash for Ultrafiltration Membrane

•Top Backwash: Pump filtered water from inside the fibers to the outside to remove accumulated substances. Backwash flow rate: 60-100 L/m²/h, duration: 30-90 seconds.

UF Membrane Backwash Bottom Step
IV. Bottom Backwash for Ultrafiltration Membrane

•Bottom Backwash: Continue the reverse water flow to remove residuals from the bottom of the fibers. Backwash flow rate: 60-100 L/m²/h, duration: 30-90 seconds.

UF Membrane Forward Flush Step
V. Forward Flush for Ultrafiltration Membrane

•Forward Flush: Use feed water to flush the system, removing remaining solids and air. Flow rate same as backwash, duration: 20-60 seconds.

Backwash Cycle:

Perform backwashing every 20-60 minutes. Adjust the exact timing based on actual operating conditions and feed water quality.


2. Chemically Enhanced Backwash (CEB)

Chemically enhanced backwash improves cleaning effectiveness by adding chemicals to the backwash process. The steps are as follows:


Chemical Addition: Choose the appropriate chemical agents based on the type of foulant, such as chlorine, acid, or base.

Sodium Hypochlorite (NaClO): 10-15 ppm or add 1-5 ppm in feed water.

Acid Cleaning (Hydrochloric or Citric Acid): 500-1000 ppm, adjust pH to 2.

Alkaline Cleaning (Sodium Hydroxide): 0.05% sodium hydroxide (pH=10) + 0.1% sodium hypochlorite.

Soaking Step: Allow the chemicals to react with contaminants by soaking for 5-20 minutes.

Intermittent Air Scour: Apply air scour intermittently during soaking to increase effectiveness.

Routine Backwash: After soaking, perform a standard backwash to remove particulates and purge residual chemicals.


Perform chemically enhanced backwash every 3-7 days. Adjust the exact timing based on actual operating conditions and feed water quality.


3. Clean-In-Place (CIP) Procedure

When backwashing and CEB are insufficient to restore membrane performance, CIP is a thorough cleaning method. The steps are as follows:


Pre-Cleaning Backwash: Perform a routine backwash to remove loose contaminants.

Chemical Circulation: Circulate cleaning solution through the membrane at controlled flow rates and temperatures.

Inorganic Fouling (e.g., Calcium Carbonate, Iron Salts): 0.1-0.3% hydrochloric acid or 1% citric/oxalic acid solution.

Organic Fouling (e.g., Fats, Humic Acids): 0.1-0.3% sodium hydroxide solution.

Microbial Fouling (e.g., Bacteria, Viruses): 0.2-0.5% hydrogen peroxide or 1000-3000 ppm sodium hypochlorite solution.

Chemical Dosage:

Sodium Hypochlorite (NaClO): 10-15 ppm or add 1-5 ppm in feed water.

Acid Cleaning (Hydrochloric or Citric Acid): 500-1000 ppm, adjust pH to 2.

Alkaline Cleaning (Sodium Hydroxide): 0.05% sodium hydroxide (pH=10) + 0.1% sodium hypochlorite.

Soaking: Allow the cleaning solution to soak in the membrane module to break down contaminants. Soaking time generally ranges from 30 minutes to several hours.

Final Rinse: Thoroughly rinse the membrane module with clean water to remove all cleaning agents and dislodged contaminants.

Cleaning Process Time Control

•Backwash Cycle: Perform backwashing every 20-60 minutes, each cycle lasting 30-90 seconds.

Chemically Enhanced Backwash: Perform chemically enhanced backwash every 3-7 days.

Clean-In-Place: When the transmembrane pressure (TMP) increases by 1.0 bar (under the same temperature) or the permeate flux decreases by 20% (under the same feed pressure), CIP cleaning is required.


4. Maintenance Tips

Monitor System Performance: Regularly check TMP, flux, and permeate quality to detect early signs of fouling.

Use High-Quality Chemicals: Ensure the use of high-quality, compatible chemicals for CEB and CIP to avoid membrane damage.

Regular Maintenance: Perform backwashing, CEB, and CIP according to a routine schedule based on feed water quality and system performance.

Inspection and Replacement: Regularly inspect the membrane modules and replace them if necessary to maintain optimal performance.
