Low-Pressure Spiral RO Membrane Element ES15-U

RO element with large membrane surface area, realizing high water permeate flow at ultra-low pressure operation.

Outline

ES15-U is a fully aromatic polyamide ultra-low pressure spiral RO membrane element suitable for applications such as intermediate RO, post RO or recovery RO in ultrapure water production systems etc. Its excellent features allow drastic reduction in start-up time, facility costs and a required installation space.

Features

• The water permeate flow increased significantly while maintaining the IPA rejection at 93% which is equivalent to the previous model.
• Non-organic iron and TOC elution levels are minimal due to the maximized cleanliness of the membrane element.
