Brief Introduction
The ULP series is an ultra low pressure aromatic polyamide composite reverse osmosis membrane element developed by UMEK for the desalination of surface and groundwater.
It operates at approximately 2/3 the pressure of conventional low-pressure brackish water membranes and can achieve a desalination rate of 99.5%, providing a high desalination rate while meeting the system's water production requirements under low pressure conditions.

Why should the RO membrane system with reverse osmosis scale inhibitor be pretreated?The purpose of pretreatment is to remove or reduce the substances in the feed water that may cause membrane contamination, scaling and damage to the permissible range of the reverse osmosis membrane system, so as to
We are excited to invite you to visit Booth No. 238 at the upcoming 2024 WQA exhibition in Orlando, FL, USA. At our booth, we will be showcasing a range of cutting-edge water treatment solutions, including our flagship product, RO membranes.Reverse Osmosis (RO) membranes are at the heart of our wate
Reverse osmosis membranes play a crucial role in water purification by effectively removing dissolved salts, colloids, microorganisms, and organic compounds. However, the performance of these membranes can deteriorate due to various factors such as surface fouling, physical and chemical changes, and
