Ghahremani has been banned by anti-corruption committee of Iran Football Federation on Monday.
Ghahremani made wrong decisions during Sepahan-Persepolis match in Isfahan last month, where the visiting team lost 2-0.
The referee showed Meysam Hosseini a straight red card for a controversial foul on Sepahan defender Shoja Khalilzadeh just two minutes into the match.
He also awarded Sepahan a penalty and Hadi Aghili found the back of the net.
TV replays showed Ghahremani made mistakes.
Iranian referee Mohsen Ghahreman has been suspended from all football activities until further notice.
