Requesting interpretation of Jewish ritual

[testing@maildelivery.pw]

Hi,

can someone please explain the ritual I found on the Internet here:

נֹשֵׂא עָו‍ֹן וְעֹבֵר עַל פֶּשַׁע • תשליך בחצה"ק סאדיגורה - חדשות JDN

I want  to know :

1. what is the purpose ?
2. what is the name of this ritual ?

Thank you
