“…The reactors may be made very compact due to their ability to handle a large amount of biomass, making them an attractive choice for use in tiny wastewater treatment plants. One of the most notable advantages of the linked growth process over other types of bio filters is its uniformity over a wide range of effluent flow rates and concentrations [ 14 , 15 ]. The properties of the packed bed materials used in the reactors determine the structure of the bio films formed.…”

The municipal wastewater may be treated using a number of different types of fixed beds that have a larger surface area. Since the fibrous materials have such a large specific surface area, they are frequently considered to be the best option for greater microbiological support and treatment efficacy. In this research, natural fibre materials such as coir fibre and areca husk were investigated for their potential to function as fixed aerated beds for the treatment of municipal wastewater. During the experiment, variations in the chemical oxygen demand (COD), biological oxygen demand (BOD), total dissolved solids (TDS), and total suspended solids (TSS) of the effluent were used to determine how well the aerated fixed bed work in treating the wastewater. The most efficient operating parameters for the successful treatment of wastewater were determined to be a contact period of 72 hrs, a filter medium depth of 5 cm, and a packing density of 10 kg/m3. The reductions in BOD, COD, TDS, and TSS for coir fibre are 55%, 58.8%, 57.8%, and 51.89%, respectively, whereas the reductions for areca husk are 38.3%, 37.78%, 31.76%, and 30.56%, respectively. In the course of this experiment, the coir fibre was discovered to be marginally more effective in comparison to the areca husk.

Industrial waste from craft breweries can be used to grow microorganisms due to its high nutrient content. Reusing waste and reducing its improper disposal are great economic and environmental strategies. Thus, the objective was to cultivate Euglena sp. in benchtop 1-L photobioreactors using different concentrations of NPK-enriched (0.5-6.0 g L − 1 ) mineral medium with and without the supplementation with a mixture of brewing residues (BR-Mix) with increase of scale (30 L) and BR-Mix supplementation (30% v:v). Carbohydrates, lipids, proteins, fatty acids, and antioxidant potential) were analyzed. The BR-Mix-supplemented medium (0.5 g L − 1 NPK) yielded 15.3 ± 1.4% lipids, 35.1 ± 0.1% proteins, 9.07 ± 0.001% carbohydrates, and 61.3% polyunsaturated totty acids. The antioxidant potential was 170.9 ± 26.3 µmol eq g − 1 of Trolox. Supplementing with 25% BR-Mix resulted in a different biomass composition compared to control (without supplementation): increasing the content of carbohydrates (38.5%), paramylon (91%), and lipids (17.38%), and reducing proteins (26,6%) and antioxidant potential (41,8 µmol eq g − 1 ). Statement of noveltyThe clean industrial residues collected from craft breweries present an opportunity for cultivating microorganisms, in special Euglena sp., an interesting microalgal biomass. This potential not only addresses waste management issues but also contributes to economic and environmental sustainability by reducing improper disposal. We examined the in uence of the brewery waste mixture on enhancing the Euglena sp. growth potential. The subsequent phase of our study involved scaling up the process to a 30 L photobioreactor. Throughout our investigation, we analyzed parameters such as carbohydrates, lipids, proteins, and antioxidant potential under these conditions with a mineral medium and brewery waste.
