Toxicity Treatment in a Facultative Lagoon System

Lagoon WWTP 0.2 MGD

The biology in wastewater lagoons can be significantly impacted by toxic substances introduced from illicit drug manufacturing. Surface waters contaminated with drugs, and the chemicals used to manufacture them, are known to suppress aquatic life, including microorganisms.1

These chemical compounds inhibit biofilm formation and promote higher abundance of species equipped to survive in toxic environments. Microorganisms that can maintain cellular function in the presence of toxic waste exclude many of the essential biota needed for efficient wastewater processing.

These impacts can be applied to wastewater systems that are suffering from drug related toxic hits. The following case study describes the process of restarting the biology in a lagoon system that was killed off by methamphetamine manufacturing chemicals.

The wastewater operators in a rural Wyoming municipality noticed that the wastewater in the first cell of their 0.02 MGD facultative lagoon system turned milky white and was producing a strong odor (Figure 1). 

After several community members complained about the terrible smell coming from the treatment facility, the management began to investigate the health of the lagoon system.

They realized that the odor was a result of the plant biology dying from toxic chemicals introduced to the system. These toxins were allegedly dumped into the collection lines from a meth lab that was busted shortly before the wastewater system started to smell.

An occupant of the meth lab confessed to flushing the meth making chemicals down the toilet when law enforcements were sighted outside the residence. To quickly restore biological treatment in thelagoons, the city contacted BioLynceus®.

A combined regimen of ProBiotic Scrubber® II (PBII) and Potassium Permanganate (PP) was applied to the first treatment cell. Daily doses of PBII were applied for 14 days. The PP was supplemented to provide oxygen to the lagoon system and speed the reaction time of the PBII.

After five days of bioaugmentation, the smell from the lagoons dissipated. By the end of the two-week treatment, the basins were properly processing influent wastewater.

The lagoon system was also brought back to a healthy color.

BioLynceus®’ bioaugmentation plan quickly restored biological wastewater treatment in the facultative lagoon system.

BioLynceus® ProBiotic Scrubber® II provides a biological solution for lagoon toxicity.

Wastewater treatment utilities receiving inputs from industrial and anthropogenic sources are highly susceptible to toxic waste inputs. Toxic loads are often sporadic and can be extremely devastating to the biomass in treatment facilities.

Chemicals used in illicit drug manufacturing can cause significant harm to the microbial communities in surface waters. Municipal lagoon systems are especially vulnerable to these chemicals, because they receive high strength influent directly from urban sources.

Managing toxic loadings at industrial wastewater treatment facilities can be challenging. Influent from food processing industries can introduce harmful cleaning products. Biota with damaged cellular structures may be unable to properly metabolize the organic substrate and nutrients in wastewater.

Toxicity Treatment in a Wastewater Lagoon System

Municipal wastewater lagoon systems are susceptible to toxic waste poisoning. Toxic loads from residences and businesses are sporadic and difficult to mitigate. When toxicity levels are high in wastewater lagoons, the biological treatment process is inhibited due to loss in biomass.
