Here are some of the most common areas where odor can occur and what can be done about it.
If the rinse waters in your process line are growing bacteria, there may be stagnant solids on the bottom of the tanks or high drag out of process chemistry combining with organics and encouraging bacterial growth. Keep solids to a minimum and use filtration if they build up. Hubbard-Hall’s Aquapure Bio LSM can be used to alleviate the odor.
Accumulation of solids at the bottom and sides of a tank can lead to odor from bacterial growth. Sulfate in the water, or a carryover of sulfur from oils, can act as a source for bacteria growth producing a sulfide odor. The best treatment for this is maintenance with Aquapure Bio 52L which offers an alternate oxygen source for bacteria and eliminates the source of the problem (bacterial growth).
Oil/Water Mix Odor
Waste oils collected and held in a tank may contain sulfur compounds and cause bacterial growth creating a sulfide odor. We suggest the addition of Aquapure™ Bio 20, a “friendly” bacteria and Aquapure Bio 52L, for odor control in flowing water, pipes, collection systems and lift stations.
Evaporator Odor and Foam
Odor can build as the water is driven off and the waste is concentrated. Because most evaporators are enclosed, sulfur reducing bacteria can flourish with low oxygen and high temperatures. Adding Aquapure Bio LSM sor Aquapure Bio 52L will effectively control odor along with Aquapure Bubble Breaker to maintain low to no odor and foam in evaporators. Sludge in evaporators can also be a source of odor, we recommend Odor Zap for this type of odor. Odor Zap can be injected before pressing sludge to eliminate odor in sludge.
High TSS Odor
When high total suspended solids occur, Hubbard-Hall offers several products to eliminate the odors. Coupled with best practices, the Aquapure Bio line can help maintain a better work environment for you and your workers. These products work to replace the offending bacteria with a population of healthy, friendly bacteria which overpopulates the bad bacteria. The alternate oxygen source and special bacteria/enzymes eliminate the sulfur growing bacteria that is giving off the hydrogen gas (odor).
