How Reverse Osmosis works –
Your new SPECTRUM Premier Twist-Lock (PTL) Reverse Osmosis (RO) system is composed of a 3-stage system manifold, a PTL carbon block (PTL-CB)
pre-filter, the reverse osmosis membrane (PTL-RO), a storage tank, a PTL-CB post-filter and an air gap tap to deliver the filtered water to your counter-
top. First the water goes to the pre-filter, which is a replaceable cartridge that reduces chlorine, odour, sand, silt, dirt and other sediments to improve
the taste of your water. Next, the water flows to the Reverse Osmosis membrane, which is a tightly wound membrane that reduces the total dissolved
solids (TDS) and organic matter. The water goes from the membrane into the storage tank. A diaphragm inside the tank keeps the water pressurized
to about 30 psi when the tank is full. This is what provides the fast flow to the tap. When the tank is empty, it should be pressurized to 5 – 7 psi. As
water is drawn to the tap, it flows from the storage tank through the final filter. The final stage PTL-CB post filter reduces any remaining tastes and
odours to provide cleaner great tasting drinking water direct to your tap.
Your system also has an automatic shutoff valve to conserve water. When the storage tank is full and the tap is not open, pressure closes the shutoff
valve to stop flow of water with contaminants to the drain. After enough drinking water is drawn from the tap, the pressure in the Reverse Osmosis
system drops and the shutoff valve opens to allow the tank to be re-filled.
Reverse osmosis uses a membrane that is semi-permeable, allowing cleaner water to pass through it, while rejecting the contaminants that are too
large to pass through the tiny pores in the membrane. This quality reverse osmosis system uses a process known as cross-flow to allow the membrane
to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected contaminants
away from the membrane and down the drain. The process of reverse osmosis requires a driving force to push the water through the membrane - the
pressure provided by your home’s water supply is sufficient: 40 to 100 psi.
What it removes –
The SPECTRUM Premier Twist-Lock reverse osmosis system has achieved NSF/ANSI 42 & 58 certification. NSF International is a world leader in
standard, development, product certification, education and risk management for public health and safety. Your Reverse Osmosis unit, PTL-CB, will
reduce Chlorine, Odour, Particulates, Sediment, and improve taste, according to NSF 42 Standard. The PLT-RO will also reduce Total Dissolved Solids
(TDS), Pentavalent Arsenic, Hexavalent Chromium, Lead, Cadmium, Cysts, Nitrate Plus Nitrite, Nitrate and Nitrite according to NSF 58 Standard.
