PUMP
The Hydroid system uses a multi-stage centrifugal stainless-steel pump. If any damage occurs
to your system’s pump, a rebuild kit is available. Contact HydroLogic for parts and warranty.
PUMP PRESSURE GAUGE
The pump pressure gauge measures the pressure of the water as it enters the first membrane
in the system.
MEMBRANES
The Hydroid system comes with USA made, Commercial-Grade Hi-Flow Membrane Elements.
Membranes separate impurities from water through the reverse osmosis process.
CONCENTRATE PRESSURE GAUGE (DRAIN)
The CONCENTRATE pressure gauge (drain) measures the pressure of the CONCENTRATE
(drain water) as it exits the last Membrane of the system. Subtracting the CONCENTRATE
pressure from the pump pressure will give the pressure drop across the Membranes.
CONCENTRATE FLOW METER (DRAIN)
The CONCENTRATE flow meter (drain) measures the amount of wastewater the system is
sending to drain as gallons/liters per minute.
PRODUCT FLOW METER (PURIFIED WATER)
The PRODUCT flow meter (purified water) measures the amount of PRODUCT water (purified
water) the system is producing as gallons/liters per minute.
BLEND VALVE
Allows for a mixture of post-carbon treated water into the RO’s PRODUCT water (purified
water) to achieve desirable PRODUCT (purified water) TDS and higher flow rates.
IF THE SYSTEM HAS AN ANTI-SCALANT FILTER, THE BLEND VALVE MUST
REMAIN CLOSED. THIS IS TO AVOID INGESTION OF ANY CHEMICALS AND
CAN BE TOXIC FOR AGRICULTURAL USE. HL 11595
