The Economics of Direct Steam Injection in Wastewater
Sludge heating, to maintain temperature in anaerobic digesters, is typically performed by utilizing indirect heat methods, specifically heat exchangers that use hot water as a media source. Increasingly, direct steam heating is being explored as an alternative means of maintaining digester temperature. It is shown that direct steam injection heaters have advantages in the area of size, cleanliness and reduced maintenance requirements.
