There is also a shuttle bus from the airport to Charleroi Sud station (€2.70). You can then get a train to Brussels, and an onwards train to the airport.
If you take the train, the machine that sells the bus tickets also sells bus+train tickets. You can check the schedules and fares or buy the ticket at

shuttle and see what will fit best.
Just in case, I was there on Saturday and the price of the shuttle bus to Charleroi Sud station has gone up to €3.
