Product Description

LP series is mainly aimed at the pure water market, and have the characteristics of large flux, low energy consumption, and stable operation. This series of membrane elements is suitable for desalination treatment of water sources such as surface water, groundwater, tap water and municipal water supply with a salt content below 2000ppm. It is mainly used in various application scenarios such as commercial pure water, industrial water treatment, food and beverage processing, biopharmaceuticals, and direct drinking water in buildings. It can achieve high water production under low pressure while meeting the requirements of desalination rate, thereby greatly reducing equipment costs and operating costs, and improving the economic benefits of users.


Product  Highlights

1. Large flux and low operating energy consumption;
2· Stable and durable operation;
3· Adapt to various inlet water quality and temperature conditions in different regions.
