In　this　paper,　the　influences　of　different　parameters　on　the　fouling　process　were　simulated.　The　asymptotic　fouling　curves　varying　with　time　were　obtained.　The　fouling　rate　and　asymptotic　fouling　resistance　increase　with　the　fluid　velocity　decreasing　and　the　increasing　of　heat　transfer　surface　temperature,　solution　temperature,　hardness,　alkalinity　and　pH　of　the　solution.　The　influences　of　different　parameters　on　the　fouling　process　were　analyzed　to　understand　fouling　mechanisms.
