You issue the Secure Erase command. My SSD is my primary drive running Windows, so when I format, I just boot to PartedMagic on USB. It takes about 5 or 10 seconds for my SSD to format using Secure Erase.
In most cases you're after the the ATA secure erase command. Read the hdparm man page, look for --secure-erase.
SSDs can only tolerate a limited number of writes. A secure wipe of a SSD would significantly reduce its lifespan.
I know, which is also why it's so hard to wipe it. It seems that SSDs are built with self preservation in mind and it'll try its hardest to avoid a write.
