START-UP PROCEEDURES:
Connect and turn “on” membrane supply gas making sure that all product inlet, outlet valves, & sample faucet are closed. Pressure setting will be based on product to be introduced but never exceed 60 psi.  Note: a good starting point is 30 psi.

Pressure gauge on top of Tri Clamp Cross should climb to match membrane regulator gauge setting.

Open Sample Faucet to Purge Gas assuring that the adjustable sample valve control is open by turning counter clockwise. When pressure drops close faucet and allow pressure to climb back to original setting.  Repeat this process two or three times to assure proper gas flow is passing through membrane.

Open Sweep Gas Flow Control and adjust to 5 SCFH {gas will be venting from the top of the flow meter}

On models equipped with Flo Jet Booster Pump adjust pump feed regulator to 2 psi. Higher than the membrane supply setting, i.e.: 32 psi. If starting with membrane regulator feed set @ 30 psi. Introduce supply product to inlet of unit or Flo Jet Booster Pump and inspect for leaks

Open inlet valve allowing product to flow through system and open sample faucet to purge with product.

Pour samples of product from sample faucet and adjust flow rate with adjustable sample valve control.  Gas level adjustments should be made to obtain desired results by adjusting both the membrane supply gas and product inlet to maintain a 2 psi. differential keeping the product pressure 2 psi. higher than the membrane supply gas.   If not using Flo Jet booster pump, inlet pressure of product can be tested by turning off membrane gas supply and opening sample faucet to relieve line pressure, then close faucet and monitor the Pressure gauge on top of the Tri Clamp Cross.  Controlling the pressure differential is essential to obtain desired results and to prevent membrane damage!

Utilizing the Sweep Gas adjustment will allow for removal of CO2 from incoming product as it passes across membrane.  Increasing from 5 SCFH to a higher setting will remove more CO2! Once desired results have been obtained from sample faucet product outlet can be opened to utilize product for package filling or dispense purposes.

Managing flow rate of product will be necessary to maintain consistent results.  Staying within the specified flow rates will assure quality results!

Controlling flow rate can be achieved with utilizing a counter pressure fill or use of a multi setting butterfly outlet valve!

SHUT DOWN / MAINTENANCE PROCEDURE
Upon completion of use the system must be properly flushed and cleaned to protect membrane from damage and extend service life.

Flush with water following same procedure as introducing product assuring both liquid and gas pressure remain in stated parameters.  Open sample faucet to flush as well as outlet port.

Introduce mixture of Desana Max chemical and allow to flow through system until color change matches specified chart. (see attached)  Allow to soak for 10 minutes and flush with water.

Purge product line of water by allowing Flo Jet Pump to suck dry until air is pushed out the sample faucet, on models without Flo Jet Booster Pump it will require a reverse purge process (see below)

Reverse gas purge can be accomplished by allowing membrane to be fully pressurized by closing all inlet and outlet valves and then opening the inlet valve allowing liquid to be pushed from gas pressure.  Close the inlet and allow pressure to build and then repeat two to three times purging most of the water from membrane.

Sweep gas should be adjusted to 5 SCFH and allowed to vacuum moisture from membrane for at least 30 minutes and then close sweep gas adjustment knob to hold gas pressure within the membrane. For best results it’s suggested to keep gas pressure applied to membrane by keeping positive gas pressure on system to prevent membrane from becoming wetted!

If System is to be taken off line or stored without positive gas pressure being applied to membrane the 5 SCFH Sweep Gas should be continued for a min. of 1 hr. to condition membrane prior to storage. Membrane should be charged with Nitrogen or Mixed Gas and isolated by closing all valves preventing oxygen from making contact with membrane which will protect it from contamination!
