Why is it good to keep a Low Total Suspended Solids (TSS)
It seems counter-intuitive that wastewater with low Total Suspended Solids (TSS) is more difficult to treat than wastewater with higher suspended solids. However, this statement is very true. When the Total Suspended Solids (TSS) are low, it may be difficult or impossible to form floc. Forming floc is necessary to trap and encapsulate suspended solids and other impurities. By adding bentonite clay, as an aid to forming floc, the newly formed clay flocs act like sponges to adsorb solids, metals and other contaminates.
Knowing If a Body Feed Will Help Your Treatment
When bentonite clay is used in this way, to aid floc formation, in low TSS wastewater streams, it is called a Body Feed. Jar testing should be conducted to determine if adding a Body Feed will aid the treatment process. Body feed clay is inexpensive and can be used economically even at high flow rates.
