Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the State Oceanic Administration. This standard is under the jurisdiction of the National Marine Standardization Technical Committee (SAC/TC283). Drafting organizations of this standard. Tianjin Seawater Desalination and Comprehensive Utilization Research Institute of State Oceanic Administration, Tianjin Tanggu Zhonghai Anti-corrosion Technology Development the company. The main drafters of this standard. Cheng Guochen, Wu Yunfang, Yin Jianhua, Jiao Chunlian, Wu Dongxia, Xu Xu. Measurement of scale inhibition performance of scale inhibitor for seawater desalination membrane Artificial concentrated seawater calcium carbonate deposition method

1 Scope

This standard specifies the method for measuring the scale inhibition performance of scale inhibitors for seawater desalination membranes by the artificial concentrated seawater calcium carbonate deposition method. This standard applies to the determination of the scale inhibition performance of calcium carbonate as a scale inhibitor for seawater desalination membranes.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Artificialconcentratedseawater The test water prepared by artificially simulating the main components and concentration of concentrated seawater in the reverse osmosis desalination process.

4 Principle

Artificial concentrated seawater is used to simulate the process conditions of reverse osmosis desalination technology, by adding a certain amount of scale inhibitor for seawater desalination membrane and heating Under the conditions, the accelerated decomposition of calcium bicarbonate into calcium carbonate precipitates. Measure the calcium ion concentration in the clear solution after stabilization, the calcium ion concentration is more Larger, the better the scale inhibitor for desalination membrane.

5 Reagents and materials

Unless otherwise specified, only use analytical reagents. 5.1 Water. According to GB/T 6682 level 3 water requirements. 5.2 Potassium hydroxide solution..200g/L. 5.3 Triethanolamine solution. Triethanolamine and water are mixed at 1.2 (volume fraction). 5.4 Hydrochloric acid solution. Mix concentrated hydrochloric acid and water at 1.1 (volume fraction). 5.5 Scale inhibitor solution for seawater desalination membrane (1mg/mL). 1.00mL solution contains 1mg scale inhibitor for seawater desalination membrane (on a dry basis).
