Description

In the field of waste water treatment of industrial waste waters, we are primarily prepared to solve nitrification and denitrification processes. This concerns removing the nitrogen pollution, it means removing of nitrogen pollution from ammonia (N-NH4+), nitrites (N-NO2-) and nitrates (N-NO3-), so called nitrification and denitrification proesses, from industrial and rendering waste waters. Mentioned waste waters are characterized by high concentrations of nitrogen from ammonia, nitrites, nitrates (N-NH4+, N-NO2-, N-NO3-) and organic pollution (BOD) content by the help of nitrifying (Nitrosomonas and Nitrobacter) and denitrifying (Paracoccus denitrificant) bacteria.

Lentikats biotechnology brings a high rate and stability of the nitrification and denitrification processes, primarily during application for industrial waste water treatment with a high nitrogen concentration. In comparison with the classical waste water treatment plants, lentikat technology has lower investment and operational costs. Optimal temperature of Lentikats biotechnology is 20-30ºC, limit temperature is 15ºC.

Lentikats biotechnology brings a principal reduction of the production of waste and thus contributes to significant "greening" of this field. In the event of industrial waste water treatment with a low (or zero) organic pollution content, a low production of sludge is achieved (up to 160 times lower!) and zero operational costs are achieved for the external organic substrate consumption in the nitrification process.

Lentikats biotechnology can be implemented simply into current biological waste water treatment plants without the necessity of additional investment costs.

Lentikats technology advantages can be summarized in several fundamental points:

• Intensified Processes from a High Concentration of Biomasses in Lentikats Immobilzed Biocatalysts
• High-Speed Nitrofication and Dentrification Processes – approx. 500-1000 mg N (NH4+, NO3-) per/hour per/kg of Lentikats biocatalyst
• Lower Investment Costs for the Building of New Waste Water Treatment Plants
• Low Production of Excess Biomass
• Savings on Energy and Operational Costs
• Increased Resistance to External Factors (nitrogen concentration, pH, heavy metals)
• Process Stability and Regulation
• Sequencing Nitrification before Dentrification
• Significant Decrease in Costs for Regeneration and Biomass Liquidation
• Continual Operation Mode

F.A.Q.

Which areas of biological treatment plants is Lentikats biotechnology useful and most effective in? Lentikats biotechnology is used in oxic processes (nitrification of immobilized nitrified microorganisms) and in anoxic processes (denitrification of immobilzed dentrified bacteria). In oxic processes, immobilized, nitrified bacteria provide progressive, nitrification speed. Their constant presence and their level of concentration is not dependent upon sludge age. In parts of the anoxic process, a concentration of dentrified bacteria is many times higher and provides a significant increase in dentrified capacity. With relevance to the opening of new treatment plants, this means a significant decrease in requisite dentrified volume which, in turn, dramatically decreases investment costs.

Using Lentikats biotechnology to intensify efficiency in existing treatment plants is the most effective solution in the fight against the most concentrated currents (sources) of nitrate pollutants, including septic water. When applied in this way, Lentikats biotechnology decreases stress caused by other substances in existing treatment plants, increasing the plants’ overall efficiency and ability to eliminate nitrate pollutants.

How does Lentikats biotechnology reduce the production of excess biomass? When applied in processes for the elimination of nitrate pollutants (i.e. N-NH4+, N-NO3-, N-NO2-) Lentikats biotechnology immobilizes nitrified and dentrified bacteria. With traditional treatment technolgies, these pollutants are deposited into biomass, resulting in a sludge dry residue rate of approx. 4 g/l., with a concentration of nitrified bacteria of around 1%. If the waste water is not polluted with organic substances (low values of COD and BOD) it is necessary to add an external agent, such as methanol, to prevent the growth of biomass organisms. Lentikats biotechnology employs nitrified bacteria immobilized in a PVA matrix and, therefore, adding external organic substrates to these growths is no longer necessary. This process dramatically reduces the production of excess biomass.

Does apllying Lentikats biotechnology/biocatalysts increase costs? In order to appreciate the financial benefits of applying Lentikats biotechnology/biocatalysts, one must first understand the entire concept of waste water treatment plants. In essence, it may be said that applying Lentikats biotechnology is very efficient. Its application in treatment processes to eliminate nitrate pollutants results in stabilized nitrification and dentrification systems and an increased nitrification and dentrification capacity in existing systems for the elimination of nitrate pollutants. Lentikats biotechnology also optimizes the entire system of eliminating nitrate pollutants or, in other words, enables optimal utilization of COD and oxygen consumption in oxic processes. Stable nitrification and dentrification processes mean that the overall concentration of nitrogen in treatment drainage systems is constant and always in accordance with legislative regulations for nitrate pollutant discharges, eliminating the risk of legal fines for violating laws. Furthermore, a constant and increased nitrified capacity leads to reduced organic substance degredation (in comparison to traditional treatment processes, Lentikats biotechnology can reduce the level of COD degredation to 80%). This results in a higher percentage of utilized oxygen in oxic processes for oxidizing nitrate pollutants and a reduction in necessary provisions, respectively.

Using Lentikats biotechnology for the building of new waste water treatment plants for industrial drainage (high concentrations of nitrate pollutants, low values of COD or BOD) is an optimal alternative for utilizing oxygen in oxic processes and external, organic substrates in anoxic processes. As a result of these alternatives, the provision of external, organic substrates in oxic processes becomes obsolete (oxygen is not consumed in the degradation of organic substances or for the creation of biomass). With Lentikats biotechnology, the generation of excess biomass is 160 times lower than in traditional technologies and costs tied to drainage, stabilizing and eliminating biomass is reduced significantly, making waste water treatment plant operations significantly more economical. Increased nitrification and dentrification capacities are important factors in waste water treatment and logically connected to reduced costs for volume activations and dentrification. From this perspective, the savings in volume and subsequent investment costs in oxic processes is around 10%, and 60% in anoxic processes, with respect to investments for building waste water treatment plants.

All of the aspects of Lentikats biotechnology listed above for the operation of waste water treatment plants are transcended by the costs tied to regular modifications of Lentikats biocatalysts and result in more efficient operations.
