Intention of this research is to improve;repair the quality irrigate the PDAM , [so that/ to be] direct drinkable by society. As variable to be done: Pressure pump by variable ( Psi) : 90,95,100,105,110 ; Current debit ( ml / second) : 400,450,500,550,600 The result of this research: That membrane of Reverse Osmosis able to degrade the dissolve solid at drinking water by effectiveness 96,05% that happened at osmotic pressure 100 Psi and charge 500 ml / sec of where Total inexistence of Plate Coliform ( TPC) and also Escherichia Coli(E.Coli) at water yielded. Pursuant to analysis trend got by increasing [it] time of ability of reverse osmosis progressively down. calculation dive two concentration year reach the this 44 NTU, is caused by each;every one week will be happened [by] the dissolve solid increase dissolve solid concentration ( TDS) [of] equal to 0,45 NTU.
