The secondary membrane separation experimental machine (DMJ60-2) can be equipped with ceramic membrane components, organic microfiltration, ultrafiltration, nanofiltration, and reverse osmosis membrane components. It can achieve single level filtering or multi-level continuous simultaneous filtering; At the same time, ceramic membrane filtration, ultrafiltration, and nanofiltration membranes can be activated simultaneously, and reverse osmosis membranes can complete the clarification and filtration of product solutions, including graded ultrafiltration, nanofiltration concentration, desalination, alcohol removal, and reverse osmosis concentration; Complete the collection of product solutions in segments according to their molecular weight within the same time period, and the entire process is continuous and controllable; Concentrate and clear night separately collected

1. All stainless steel welding adopts automatic argon filling protection, single sided welding, and double-sided forming. The internal and external surface quality of the pipeline is excellent. Easy to operate, clean and hygienic, safe and reliable;

2. At the same time, ceramic membranes, organic microfiltration membranes, organic ultrafiltration membranes, organic nanofiltration membranes, and organic reverse osmosis membranes can be installed. Within the same time period, the product solution can be graded and filtered according to molecular weight, collected in stages, and concentrated. The entire process is continuous and controllable;

3. It can achieve single stage filtration or two-stage continuous simultaneous filtration, and each stage can be individually replaced with different membrane components, making disassembly convenient;

4. Collect separately through liquid and concentrated night;

5. Equipped with overpressure protection, ideal pressure can be set, and the use process is very safe;

6. Configure a variable frequency control system that can adjust pressure and flow through variable frequency;

Two electromagnetic diaphragm pumps, one high-pressure plunger pump, one ceramic membrane shell, one reverse osmosis membrane shell, one ceramic membrane element, one organic microfiltration membrane element, one organic ultrafiltration membrane element, one organic nanofiltration membrane element, one reverse osmosis membrane element, four pressure gauges, two material tanks, one electrical control system, one frequency conversion control system, one overpressure automatic protection system, pipeline rack Several valves and their connecting fittings.
