Main culprits: CaCO3 and (rarely) SiO2
Causes drop in product water quality
In severe cases causes drop in concentrate flow
(increase in pressure drop)

55. OTHER FLUX ENHANCEMENT METHODS
Electrical Methods
Used for fouling due to charge interactions between charged solutes and the
membrane
An 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 Jets
Unsteady 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 Flow
Pulsations in the feed or permeate channels obtained with pistons

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%

57. 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
