Reverse osmosis (RO)maida hankali sake amfani da ruwa

Ko shiri ne na ruwa mai tsafta ko sake amfani da ruwan sharar masana'antu, yayin amfani da fasahar reverse osmosis (RO), yana daure ya samar da wani kaso na ruwan da aka tattara. Saboda ka'idar aiki na reverse osmosis, ruwan da aka tattara a cikin wannan bangare sau da yawa yana da halaye na babban salinity, high silica, babban kwayoyin halitta, babban taurin da sauransu. Bisa la'akari da irin waɗannan halaye, sau da yawa muna buƙatar zaɓar wasu matakan don tattara ruwa bisa ga ƙayyadaddun yanayi, don guje wa ɓata albarkatun ruwa da samun manufar rage farashi da haɓaka aiki.

Na farko, hanyoyin magance ruwa na gama gari don shirya ruwa mai tsafta:
