MERO ADVANCED UNITs come with everything above making it a very complete and advanced system producing TDS free and Chlorimine free clean water.  Some people have different needs so the following options are available.

Available Options

Black Color is Standard; however White is available

GPD- standard is the 100 GPD RO Membrane ; 200, and 300 GPD are available options

Additional DI Resin Canister –Some prefer running dual DI canisters to lengthen replacement time.

Booster Pump Kit –If city water pressure is below 45 psi a Booster kit may be needed to increase membrane performance.   Check the pressure gauge included with every MERO system.

Drain saddle — used so waste water goes down sink drain

Under sink inline adapter –3/8 Female x 3/8 Male Thread with Quick Connect Fitting for 1/4 inch Tube.  Fits into Most Undersink Hoses.

MERO 100 GPD 5 Stage ChloraMEno RODI WATER FLOW SEQUENCE

STAGE 1 and 2 CANISTERS  are full of MERO special catalytic carbon (CC) in refillable cartridges.   Incoming city water passes first through TDS Probe 1 indicating how much dissolved solids are in your city water.  The first 2 canisters are full of  catalytic activated carbon (CC) designed to reduce chloramines and ammonia.  Carbon also removes chlorine, organics, and other toxic chemicals from the water.  Reducing chlorine, chloramine, ammonia, etc is also important for extending RO Membrane life, as membranes are not chlorine/chloramine tolerant.

Flush kit after Dual Catalytic Carbon. Carbon releases dust and particles, especially when cartridges are being refilled.  To avoid pushing this dust into the next chamber we have added a Custom Flush Valve kit to rinse the carbon.  After refilling a cartridge open the flush valve to run water through the GAC to rinse it.  Once water comes out clear close the valve allowing water to move to Stage 2.

STAGE 3 CANISTER has a 1 Micron Sediment Filter which removes sediment and other particles of 1 micron or larger.  This includes any carbon particles that came loose from the first 2 stages.  This filter removes silt and other particulate matters that may clog the membrane.

PRESSURE GUAGE tests the pressure entering Stage 3 The RO Membrane.  Optimal pressure is between 45-85 psi.  Minimum is 40 psi. Also used to check for drops in pressure due to dirty sediment filter.

STAGE 4 RO MEMBRANE  The membrane reduces TDS total dissolved solids, such as salts, heavy metals, or calcium.  This is the most expensive of the replacement filters.  Typically lasting 2-3 times longer than the other filters.  Our goal is to extend membrane life by allowing the GAC and Sediment filter to remove as much as possible before the membrane.  A properly functioning membrane should provide a minimum of 90% reduction in TDS (typically more, test a new one).  That’s why the MERO units have TDS Probe 2 after the membrane and before the DI Resin (Stage 4).  IE:  If city water is entering the system at 100 TDS as indicated by TDS Probe 1.  Then a good membrane will reduce 90%, leaving 10 TDS after the membrane.  This is monitored by looking at TDS probe 2 which reads after the membrane.  As this number drops, try running the MERO membrane flush kit for 15 minutes cleaning the membrane.  Membranes can deteriorate due to clogging or scaling so flushing helps extend life.  Membranes also fail due to contact with chlorine.  This could be due to high levels of chlorine or chloramine in city water, or poor Carbon (CC) filter upkeep.  Flush the Catalytic carbon from time to time, and replace as needed.  Along with flushing the membrane periodically.

MEMBRANE FLUSH KIT mentioned above is between Stage 3 and Stage 4.

STAGE 5 DI RESIN  The MERO Deionization (DI) media in a refillable cartridge is the final stage.  This resin will remove the remaining TDS and produce zero TDS water.  This is measured by TDS Probe 3.  A rise in TDS above zero lets us know the resin is becoming exhausted and may need replacing.  MERO uses color changing DI Resin which changes from blue to rust color as the resin gets exhausted; however TDS is a better indicator of when to replace the resin because the color may change to rust before it’s exhausted.  If your membrane is not working properly, it will also lead to an increase in DI exhaustion.   Also if your water has chloramines the DI will remove them; however this will burn up DI resin and be more expensive than replacing carbon.  Deionization resin reduce silica, nitrates and phosphate levels. MERO uses only virgin (not reactivated) nuclear grade color indicating resin of the highest quality.   Would you expect anything different from ME!
