COMPARISON OF BASELINE FLUXESFOR THE THREE DIFFERENT MEMBRANES

Mueller, et al, 1997

Op. cond.: 10 psig TMP, 250 ppm heavy oil, 40°C, and 0.24 ms -1

SCALE FORMATION

Main culprits: CaCO3 and (rarely) SiO2

Causes drop in product water quality

In severe cases causes drop in concentrate flow (increase in pressure drop)

Need to analyze feed and concentrate for hardness or silica

(mass balance calculation)

OTHER FLUX ENHANCEMENT METHODS

Electrical MethodsUsed for fouling due to charge interactions between charged solutes and the membraneAn electric field can be applied to the flowing fluid, with one electrode being cast on or placed against the membrane, and the other electrode within the liquid, but away from the membrane surface

Intermittent JetsUnsteady flows and large vortices can be generated with an intermittent jet of the feed pumped through a nozzle placed coaxially in a membrane tube causes the velocity of the feed to abruptly increase and then decrease resulting higher flux.

Pulsatile FlowPulsations in the feed or permeate channels obtained with pistons

Fats, oils, and grease 20-50% ethanol 30 - 60 min 25 – 55oC Solubilization

Membranes have to cleaned typically when:- Normalized Permeate flow varies by 10-15%- Normalized Feed pressure varies by 10-15%- Normalized Permeate conductivity varies by 10-15%- Pressure drop between feed and concentrate varies by 10-15%

CLEANING PARAMETERS

Membrane materials and chemistry• This determines a membrane's ability to withstand the action of the chemical cleaners

Fluid mechanics• should be pumped through the system under turbulent flow conditions• the pressures should be as low as possible, but consistent with the dP required to maintain high

flow rates

Time• most chemical cleaners complete their action within 30-60 min. Prolonged cleaning after the

optimum time may actually cause refouling of the membrane due to the filtration effect

Temperature• the temperature of the cleaning solution should be as high as possible, consistent with temperature

limitations of the membrane/module

Water quality• soft water should be used.

pH• Alkaline cleaners containing NaOH or KOH are particularly effective for organics and proteins• Acidic cleaners are primarily used to combat inorganic salt fouling
