Product Introduction

The Industrial RO Membrane 4040 is specially engineered to resist contaminants such as colloids, organic matter, and microorganisms. Compared to standard membranes, they offer enhanced durability, lower maintenance frequency, and are better suited for complex water sources. Below is a comprehensive comparison:

1. Membrane Material and Surface Structure

Item	Anti-Fouling Membrane	Standard RO Membrane
Surface Modification	Enhanced hydrophilicity and smoother surface through charge and structural optimization, reducing foulant adhesion	Unmodified surface; more prone to accumulation of organic matter and colloids
Material Enhancement	May include nanomaterials or modified polymer cross-linking for added protection	Conventional aromatic polyamide layer

2. Fouling Resistance

Item	Anti-Fouling Membrane	Standard RO Membrane
Resistance to Colloids & Organics	Strong; ideal for water sources with high fouling potential	Weak; easily blocked and fouled
Biofouling	Biostatic properties reduce bacterial growth and biofilm formation	Susceptible to microbial contamination
Application Range	Suitable for landfill leachate, electroplating wastewater, coal chemical wastewater, etc.	Suitable for stable feedwater with low pollution, such as tap water or spring water

3. Operation and Maintenance

Item	Anti-Fouling Membrane	Standard RO Membrane
Cleaning Frequency	Low; longer cleaning intervals with higher cleaning recovery	High; frequent cleaning with lower recovery rates
Service Life	Generally longer (depending on conditions)	Shorter, especially in high-fouling environments
Overall Operating Cost	Slightly higher initial cost, but lower in the long run	Lower upfront cost, but higher maintenance expenses
