Product Description
Brief Introduction
Applicable to various small-sized drinking systems, such as home drinking water purifiers, mineralized drinking fountain, etc., the residential 1812-type and 2012-type NF elements are designed for removing from water various organics, microbes, viruses and most metallic ions with two or higher valence while retaining part of the sodium, potassium, calcium and magnesium ions, etc., thus improving the mouthfeel of purified water and maintaining the content of mineral nutrition.

Precautions for Use of Dry-type Membrane Elements
Storage of Dry-type Membrane Elements
1. The membrane elements must be stored in cool and dry place, and shall not be exposed to direct sunlight.
2. The dry-type elements shall be stored in the place with temperature not higher than 45, below which temperature the elements can be stored for unlimited period.
General Information of Dry-type Membrane Elements
1. The dry-type membrane elements shall be always kept in wet condition once been moistened.
2. Only after being operated for at least 6 hours can the dry-type membrane elements be disinfected with formaldehyde.
3. The dry-type membrane elements work under the Operating Limits and Conditions and design guide identical to the wet-type elements of same specifications.
4. Once a dry-type membrane element is moistened to become a wet-type element, it shall be disposed of according to the methods of storage, preservation and cleaning indicated in this Manual corresponding to equivalent wet-type membrane element.
5.The initial adjustment and running of RO system shall be conducted in accordance with the procedures indicated in "Chapter 4 - Operation and Maintenance of RO System", and the filtered water and rejected water produced in the first one hour shall be discarded.
