1800 ~ 4000 GPD Whole House RO

Stainless steel multi-stage pump: Sometimes referred to as a "shotgun pump", this pump uses multiple stages of impellers to create pressure for the membrane. The impellers of the pump are glass-filled Noryl with poly carbonate diffusers. The pump housing, including the inlet and outlet ports are constructed of stainless steel.

Stainless steel adjustable waste needle valve (requires waste flow meter): The waste valve controls the system operating pressure (180-200 psi).

Recycle valve This option allows the system to recycle a portion of waste water back into the RO system to obtain a higher feed flow recovery (up to 60%).

Pre and post-filter gauges: These gauges monitor the pressure BEFORE and AFTER the system pre-filters. This allows the customer to know when to change out the pre-filters. A pressure differential of about 15 psi between the two gauges indicates the filters should be changed. Example: Pre-filter IN pressure is 50 psi and Pre-filter OUT psi is 35. This is a differential pressure of 15 psi.

Product and waste flow meters: This option allows customer to monitor the product and waste flow rates.

Fused Off/On safety switch: There is a switch box mounted on the RO system and is fused to protect the wiring from starting on fire in case of a motor problem.

TDS digital monitor: Customer can continually monitor the Total Dissolved Solids in the product water.

Shipping crate: Wood shipping crate for extra protection during shipments.

Ozone generator: High grade UV ozone generator sanitizes and disinfects water inside the tank through the highly effective oxidation process. A safe and environmentally friendly solution for quality water disinfection.

Recycle flow meter: This flow meter monitors the amount of water being recycled from the waste side of the membrane back into the inlet of the pump.

Tank pressure switch: The LOGIC CONTROLLED Whole House RO system can be set up for a pressurized water storage tank. If this option is selected, it is important that the air pressure on the storage tank is set at 25 psi.

3phase power supply with IEC motor contactor: Choose this option if you want to connect the system to a 3phase power supply.

50 hz electrical: Electrical supply of 50hz is common in Europe, South America, Africa, Middle Eastern, Asia and parts of Japan. (USA electrical supply is 60hz)

220 volt-60 hz: The Commercial LOGIC RO system is standard 110v power. Select this option if you prefer 220v.


Options to ICP control box:

Automatic hourly flush: This feature is a forward flow, rapid flow of water movement on the RO membrane. Flushing takes place during RO system start-up and every hour after that for 2 minute duration. Flushing helps loosen debris from the membrane surface, helping to prolong membrane life.

Feed Water TDS digital monitor: Customer may elect this option to continually monitor the Total Dissolved Solids in the product water.

High pressure cut-off w/auto restart and manual override: This switch turns off the RO system if the pressure exceeds 200 psi. A timer will try to re-start the RO system every 15 minutes. This re-start timer can be over-ridden by pushing a button.

Pre-treat lock-out with light: This feature is used when a customer wishes to turn off the RO system during any pre-treatment backwashing. NOTE: The pre-treatment control valves must be outfitted with a lock-out micro switch for this feature to be operational.

Product diversion: Diverts the permeate water to drain on system start-up for two minutes. Mostly used on high-purity water applications where the highest quality water available from the RO system is directed to the storage tank.

Permeate purge: After RO system shut-down, pure water is directed back to the RO membrane, purging all concentrated water out of the membrane housing. Ideal for high TDS applications to prolong membrane life.

Temperature 85° F maximum
pH range 3-11

Input Pressure 40-80 psi maximum
Operating pressure 200 psi maximum

Hardness must be removed.

TDS 2000 ppm maximum.

Iron 0.5 ppm maximum.

Turbidity should be removed.

Hydrogen sulfide must be removed.

Silica needs to be less than 125 ppm in the concentrate stream, anti-scalant should be considered for any levels over 75 ppm.

Water recovery up to 60% and is field adjusted by customer. (It is not recommended that the recovery be set higher than 50%. Only under certain conditions can the recovery be set higher.)

Flow rates are determined by membrane manufacturer's testing criteria of 1500 ppm NaCl solution @ 77 °F water temperature and 225 psi at 10-15% recovery.
