The data results of the national key R&D program "Development of Small and energy-saving Desert Bracky water membrane Desalination Process and Equipment Development (2017YFE0114200)", chaired by Associate Professor Du Runhong of Tianjin University of Technology, are officially released on the National Cryosphere Data Center (www.ncdc.ac.cn) and are available for download. A total of 22 data sets have been released in this project, including data on the change of lake water recovery rate with lake salt content, total dissolved solids of lake water, nanofiltration hardness removal rate of lake water, water quality data, concentrated brine treatment data of lake water desalination system, sludge density index data of lake water pretreatment, etc. In order to solve the problem of brackish water desalination in arid and semi-arid areas, a reasonable process and equipment design basis are proposed.

Data set of overall desalination rate of Tianjin Jinhai Lake desalination system (July September 2020)

After precision filtration ultrafiltration pretreatment, the water of Jinhai lake is desalted by reverse osmosis / nanofiltration system. The desalination rate of the desalination system under different mixed loading modes and different operating pressures was investigated. The desalination system adopts commercial polyamide 4040 roll type nanofiltration and reverse osmosis membrane m...
