You shouldn't have to do anything.

I believe Codeigniter/MySQL will take care of closing connections for you as you do not have persistent connections enabled ('pconnect' => FALSE) this will allow connections to be closed automatically.

https://codeigniter.com/user_guide/database/connecting.html#manually-closing-the-connection

While CodeIgniter intelligently takes care of closing your database connections, you can explicitly close the connection.

$this->db->close();
