Operation process:

Dead end mode

Cross flow mode

Filtration flux depends on:

– Water origin (ground water, sea water, surface water, residual water)

– Water analysis (Turbidity, TSS, organic matter, iron, manganese, aluminum, pH, alcalinity…)

– Pre-treatment (use of chemicals, agressive or scaling water)

– Temperature (flux is corrected below 12°C)

Filtration Mode – Filtration flux

Air Scour Mode

• Air scouring, instead of backwashing, is the primary means of

physically cleaning the membrane

1.Pressurize inside of fiber with air to ~15 psi 2.Monitor pressure decay rate 3.Look for bubbles in concentrate line (top vertical

port)
