Industrial treatment processes are known to treat a variety of nutrient loads; in which an elevated food: microorganism ratio can be exhibited. This elevated load on the biological population has the potential for undesirable conditions within the treatment processes. One of these nuisance biological growths is known as Zoogloea.
Zoogloea excretes a biopolymer which causes buoyancy in the MLSS reducing settling. Once the organism multiplies; the biopolymer overcomes the weight of the natural floc. These biological secretions have a composition of polysaccharides and proteins. An experimental method to facilitate the disintegration of the secretion is the introduction of enzymes.
Enzyme addition to the digester has shown its applicability and viability in areas where Zoogloea is found. In this preliminary study the enzyme has established desirable qualities and further research, I am confident, will uncover further benefits unknown to this investigation.
Attached is the full case study for an industrial waste treatment plant that has an issue with Zoogloea in their system.
