PI® Direct Flow reverse osmosis 450 and 450 UV

The PI® direct flow reverse osmo­sis 450 is the first phase of the PI®-Power Com­pact water treat­ment process. We rec­om­mend to use it in con­nec­tion with the PI®-Cell Vital­iz­er only.

The PI® Direct Flow reverse osmo­sis 450 is a high tech water purifi­ca­tion sys­tem with excep­tion­al­ly effi­cient pure water pro­duc­tion in com­pact size. The purifi­ca­tion process is the same two steps process as with the PI® Direct Flow reverse osmo­sis 300, but with a 28% more pro­duc­tion capac­i­ty:

  1. Pre­filtra­tion
  2. Pure water pro­duc­tion by the means of three high-effi­cient, ultra fine type 150 GDP mem­branes.

Material

Hous­ing: stain­less steel

All plas­tics in use are guar­an­teed free from so called soft­en­ers (phta­lates), bis­pehnol A (hor­mones), acetalde­hyde and anti­mo­ny (cer­tifi­cates avail­able upon request).

For max­i­miz­ing the effi­cien­cy of the water pro­duc­tion and pro­long­ing the lifes­pan of the mem­branes, the incom­ing water is puri­fied from mechan­i­cal coarse con­t­a­m­i­nants. Right after it is addi­tion­al­ly cleared from pos­si­ble unwant­ed chem­i­cal sub­stances.
Accord­ing to the DIN-stan­dard DIN EN 806–5:2012–04 the active-car­bon-block-fil­ter has to be replaced every 6 months or already after pro­cess­ing 9.000 l of the incom­ing water.

PI® Direct Flow reverse osmosis 450 membranes

PI® Direct Flow reverse osmo­sis 450 uses three high-effi­cient TFC (thin film com­pos­ite) type 150 GDP mem­branes  by Applied Mem­branes Inc. These mem­branes pro­vide at a work­ing pres­sure of 9,5 bar a near 100% purifi­ca­tion of the incom­ing water while pro­duc­ing an excep­tion­al­ly low waster water vol­ume.

The mem­branes are semi­per­me­able: Only mol­e­cules equal or small­er as the water mol­e­cule can pass through the fine pores (0,0001 µm = atom­ic size). All larg­er pol­lu­tants are dis­posed with the waste water.

The mem­branes has to be replaced based on expe­ri­ence every 3–4 years.

Zusatzausstattung

If the incom­ing water’s pol­lu­tion reach­es the lim­its, we rec­om­mend an imple­men­ta­tion of addi­tion­al fil­ters into the PI®-Power Com­pact sys­tem. For exam­ple the Antiglyphosat fil­ter-set or the Antiglyphosat fil­ter strong will be added after the PI® Direct Flow reverse osmo­sis (1), or oth­er­wise pri­or to the PI® Direct Flow reverse osmo­sis (2). These addi­tion­al fil­ters not only ensure a high water qual­i­ty, but pro­tect the mem­branes from to much strain and thus pro­long their lifes­pan.

On top of the pre­vi­ous­ly men­tioned Antiglyphosat fitler fol­low­ing fil­ters are avail­able. Those will be all con­nect­ed pri­or to the PI® direct flow reverse osmo­sis:
