Direct flow reverse osmosis

The PI®-Power Com­pact Direct Flow reverse osmo­sis is the first step towards a purest drink­ing water indul­gence. Here the feed water gets puri­fied from the coarse mate­r­i­al. On the one hand inside the pre-fil­ters (PI®-Power Com­pact 300: pre-fil­ter set; PI®-Power Com­pact 450: active car­bon block fil­ter) the sol­id mat­ter like sand or microplas­tics is removed by a sed­i­ment-fil­ter and on the oth­er hand much small­er sub­stances and chem­i­cal com­pounds are fil­tered by an active car­bon block fil­ter.

The Dire­cet Flow process requires no reser­voir, hence there’s no larg­er vol­ume of stag­nant water is pro­duced. If the sys­tem oper­ates under opti­mal con­di­tions  there is 100% no chance of bio­log­i­cal con­t­a­m­i­na­tion.

Fur­ther advan­tages of a direct flow reverse osmo­sis sys­tem:

• Con­tact pres­sure of 9,5 bar at the mem­brane sig­nif­i­cant­ly increas­es the reten­tion val­ue
• High­est rejec­tion rate of the con­tained mate­ri­als (>97,5% — 99%)
• Excel­lent pure water out­put per liter of tap water (55%)
• Low waste water out­put per liter of tap water (45%)
• Water cooled pump, hence no ther­mal issues
• Low main­te­nance costs thanks to long life 150 GPD TFC-high effi­cien­cy mem­branes
• Con­stant back flush of the mem­branes: before and after each pro­duc­tion cycle and by default every 6 hours
• Pres­sure reduc­er: Sys­tem pro­tec­tion against water ham­mer from the mains water sup­ply
• Auto­mat­ic waste water drain under high pres­sure and with anti-germ-rebound-valve
• Auto­mat­ic water qual­i­ty con­trol (TDS con­duc­tiv­i­ty)
• LCD dis­play for fil­ter- and mem­brane main­te­nance
• Mod­ern and com­pact design, extreme­ly space-sav­ing
• Sim­ple assem­bly and main­te­nance (do-it-your­self-sys­tem)
• Sim­ple and effec­tive John Guest plug-in con­nec­tors
• Food-safe mate­ri­als guar­an­teed: All plas­tic are guar­an­teed free from so called plas­ti­ciz­ers (phta­lates), bis­pehnol A (hor­mones), acetalde­hyde and anti­mo­ny (cer­tifi­cates are avail­able upon request)
