How to design a pilot-scale plan for membrane filters

Membrane filters are currently used widely in the chlor-alkali industry, but before adopting them, various chlor-alkali plants adopt a cautious approach and carry out experimental tests to varying degrees. I would like to ask everyone: how are pilot test plans generally designed, and what conditions need to be explored? # hcbbs
The options we are considering are: 1. For the validation of the process, investigate whether it is possible to shorten the brine treatment process by eliminating the pretreatment step； 2. Conduct experimental studies to investigate the variation of filtration flux over time, and determine when a constant flux can be achieved ； 3. Test the flow rate changes under different filtration pressures, and study the optimal operating parameters: filtration pressure and filtration flux ； 4. Optimization of the regeneration cycle for membrane filters ； 5. Study on the adaptability and robustness of membrane filters for the system.
Adding to the two points mentioned above: 1. Experiments on operational flexibility. II. Experiments on raw salt under different calcium-to-magnesium ratios.
The calcium-to-magnesium ratio of crude salt mainly affects the pretreatment process; in the absence of pretreatment, it has a direct impact on the filters.
