Water Purifier Water Softeners Reverse Osmosis Catalog 26 April 2018

Nominal performance GRO-50EN
* Flow* Gpd (Lpd): 50 (189.3)
* Rejection: 96%
* Drain flow control (ml./min.): 150
Nominal performance GRO-75EN
* Flow* Gpd (Lpd): 75 (283.9)
* Rejection:96%
* Drain flow control (ml./min.): 200
Note: The data above is based on internal laboratory testing.
* Nominal performances are based on a 500 ppm softened tap water at 4.5 bar, 25ºC, 50% recovery after
24 hours. Individual element flux may vary ± 15%.
The GRO-36EN, GRO-50EN and GRO-75EN are Tested and Certified by NSF International against
NSF/ANSI Standard 58 for materials and structural integrity requirements.
Here is the expected amount of water saved each year, for a family of 4 people:
Yearly water consumption: 3 lt./day/person x 1 year = 4’380 lt.
Standard RO membrane: 17’520 lt. of rejected water
GRO membrane: 4’380 lt. of rejected water
The use of GRO membranes allows a saving of about 13’000 lt. of water per year.

TLC RESIDENTIAL RO MEMBRANES
The best way to assess the overall filtration quality of a RO system is made by measuring the rejection,
which is the percentage of total dissolved solids removed from the inlet water. In other words, the higher the
rejection, the better the membrane performs. The recovery of a RO system represents the quantity of
permeate produced compared with the quantity of concentrate rejected to the drain. The higher the
recovery, the lower the rejection is.
RO MEMBRANE’S CONSTRUCTION
The spiral-wound membrane element is constructed of one or more membrane envelopes wounded around
a perforated central tube. Purified water passes through the membrane and is collected in the permeate
collection material while rejected impurities stay in the feed channel spacer.
TLC RANGE
TLC (Thin Layer Composite) range is made of 5 reverse osmosis membranes which will allow to cover any
types of needs from the customer. Dimensions of these membranes are standard; they will fit into any
reverse osmosis systems from the market.
