Last week I contacted Kevin Anderson from Austin's Hornsby Bend 
Biosolids facility to learn more about their operations. Yesterday 
he sent me this educational brochure that describes the facility 
for visitors.

Water hyacinths are still used at the front end of the greenhouse 
polishing facility, ostensibly to maximize removal of residual 
heavy metals at the beginning of the influent stream. Native 
species such as Lemna (duckweed) and Wolfia are primarily used 
throughout the rest of the greenhouse. Harvested biomass from all 
of these are incorporated into the Dillo-Dirt compost.
