Product Description

Energy Saving, High Productivity, Low Fouling Polyamide RO Membranes

ESPA2-LD from the LD Technology™ innovative low fouling membranes, offers significant cost savings with lower operating pressure requirements while providing an optimal flow

When high productivity from a membrane element is important, the ESPA family of products is the right choice. ESPA (Energy Saving Polyamide) membranes achieve high flux without compromising on the standard for high rejection. The ESPA2-LD membranes find wide applications in the industry due to the significant cost savings associated with their use.

The ESPA2-LD has a high rejection of silica and boron, and an enhanced tolerance to high pH cleaning. Combining the energy saving properties of the ESPA membranes with the low biological and colloidal fouling properties of the LD Technology™, the ESPA2-LD membranes provide you an optimum performance and greater cost savings!

With a high boron rejection the ESPA2-LD membrane is most suitable for applications such as irrigation where it is critical to maintain a very low level of boron, bottling operations and other light industrial uses.

Key benefits

• Lower operating pressure
• Lower energy consumption
• High Salt Rejection - 99.6% (99.5% minimum)
• Lowest Biological And Colloidal Fouling
• Higher rejection for impurities including Silica and Boron
• Greater tolerance to high pH cleanings

Frequently Asked Questions

What are the main advantages of using the HYDRANAUTICS ESPA2-LD-4040 reverse osmosis membrane?
The HYDRANAUTICS ESPA2-LD-4040 offers energy savings with lower operating pressure, high rejection rates including silica and boron, and enhanced tolerance to high pH cleaning, making it cost-effective and efficient for various industrial applications.
How does the HYDRANAUTICS ESPA2-LD-4040 membrane help reduce operational costs?
This membrane reduces operational costs by requiring less energy due to its lower operating pressure, along with its high productivity and fouling resistance, which means less maintenance and longer service life.
Is the HYDRANAUTICS ESPA2-LD-4040 suitable for specific industrial applications?
Yes, the ESPA2-LD is ideal for applications such as irrigation, bottling, and light industrial uses where high rejection of boron and silica are critical for water purity.
What makes the ESPA2-LD membrane more resistant to fouling compared to traditional membranes?
The ESPA2-LD membrane incorporates LD Technology™, which provides lower biological and colloidal fouling, thus maintaining high performance and reducing the need for frequent cleaning.
How does the high boron rejection of the HYDRANAUTICS ESPA2-LD-4040 benefit my water treatment process?
The high boron rejection ensures the membrane effectively reduces boron levels in water, which is crucial for applications requiring strict boron control, like irrigation and certain industrial processes.
