Wastewater sludge reduction – bioaugmentation for lowering lagoon dredging costs and improving system efficiency

Despite effective wastewater sludge reduction and treatment, solids can still accumulate at the bottom of the lagoons, resulting in short-circuiting, reduced hydraulic retention time, and ultimately poor treatment.

Lagoons offer an economical way to treat the high cost of wastewater flows generated from, pulp and paper mills, for example. Despite effective wastewater sludge reduction and treatment, solids can still accumulate at the bottom of the lagoons, resulting in short-circuiting, reduced hydraulic retention time, and ultimately poor treatment. The most common way to alleviate this wastewater sludge reduction issue is through costly dredging.

Novozymes offers a biological alternative to dredging. The combination of beneficial microorganisms, enzymes and essential nutrients stimulates biological activity in the sludge and provides a cost effective way of reducing sludge volume and improving treatment. Novozymes’ sludge minimization products are applied at the water surface and sink directly into the settled sludge layer. They are easily applied over a broad area and target hot spots where sludge has accumulated.

Effective biological wastewater sludge reduction technology

The microorganisms and nutrients in Novozymes’ BioSpikes® stimulate biological activity in the sludge layer, allowing floc particles to become larger and denser—improving wastewater sludge reduction. Denser floc particles contain less water and lead to greater compaction. The enzymes in BioSpikes® help to degrade substances that hold decaying biomass together at the lagoon bottom. Beneficial microorganisms further complete the degradation of decaying biomass and result in a lower and more compact sludge layer.

Novozymes offers unique biological solutions to assist customers in meeting their wastewater sludge reduction and solids handling goals. Novozymes’ products, powered by beneficial microorganisms and nutrients, stimulate biological activity in lagoon sludge layers to minimize settled sludge volume and reduce solids handling costs.

BioSpikes® – Sludge reduction technology for wastewater lagoons

BioSpikes® is a biological wastewater sludge reduction product that offers a new way to minimize settled sludge volume and reduce solids handling costs in wastewater lagoons. BioSpikes® are made into a dense spike that rapidly sinks to the bottom of a lagoon, and release billions of microorganisms, powerful enzymes and essential micronutrients, all specially selected for effective wastewater sludge reduction, directly into the sludge layer. This combination ensures rapid stimulation of biological activity and improved wastewater sludge reduction. BioSpikes® reduces the dredging frequency, increases hydraulic retention time, and improves overall lagoon performance.
