When selecting your membrane:
1️⃣ Check Your Feed Water TDS
If TDS > 2500 ppm, choose CPA3 or ESPA models.
2️⃣ Consider Operating Pressure
Lower pressure = lower energy cost.
3️⃣ Assess Your Application
CPA3 for high purity, LFC3 for fouling resistance, ESPA for energy savings.
4️⃣ Look for Genuine Suppliers
Always buy from authorized dealers to avoid counterfeit membranes.
