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 standard with Encapsulated Membrane Elements. Membranes
separate impurities from water through the reverse osmosis process. See Membrane
Information and Handling section of this manual for additional information.
CONCENTRATE (DRAIN) PRESSURE GAUGE
The CONCENTRATE (drain) pressure gauge measures the pressure of the CONCENTRATE
(drain water) as it exits the last Membrane of the system. Subtracting the CONCENTRATE
(drain) pressure from the pump pressure will give the pressure drop across the Membrane
array.
CONCENTRATE (DRAIN) FLOW METER
The CONCENTRATE (drain) flow meter measures the amount of wastewater the system is
sending to drain as gallons/liters per minute.
PRODUCT (PURIFIED WATER) FLOW METER
The PRODUCT (purified water) flow meter measures the amount of PRODUCT (purified water)
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 (purified water)
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
