Summary
Sequencing batch biofilter granular reactors (SBBGR) offer an effective on-site treatment for textile wastewater. This technology successfully treats mixed municipal-textile effluents and can serve as a pre-treatment for textile wastewater, reducing costs.
Area of Science:
- Environmental Engineering
- Wastewater Treatment Technologies
- Industrial Biotechnology
Background:
- Textile wastewater contains recalcitrant, toxic pollutants, necessitating complex treatment schemes.
- Current practices involve centralized treatment plants, increasing costs and logistical challenges.
- On-site treatment technologies are sought to optimize cost-effectiveness and efficiency.
Purpose of the Study:
- To evaluate the efficacy of sequencing batch biofilter granular reactor (SBBGR) for treating textile wastewater.
- To assess SBBGR's performance on both mixed municipal-textile wastewater and pure textile effluent.
- To determine the economic viability of SBBGR for on-site wastewater treatment.
Main Methods:
- Operation of two lab-scale sequencing batch biofilter granular reactors (SBBGR).
- Treatment of mixed municipal-textile wastewater in one reactor.
- Treatment of pure textile effluent in a second reactor.
Main Results:
- Successful treatment of mixed wastewater with hydraulic retention times under 10 hours.
- SBBGR demonstrated effectiveness as a pre-treatment for textile wastewater discharge.
- Operative costs were found to be €0.10/m³ for mixed wastewater and €0.19/m³ for textile wastewater.
Conclusions:
- SBBGR is a promising technology for on-site treatment of textile wastewater.
- The reactor system offers significant cost reductions compared to traditional methods.
- SBBGR facilitates effective pre-treatment, enabling safer discharge of textile effluents.

01:30Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
01:29Bioreactor Design and Operational System
Bioreactors are engineered vessels designed to cultivate microorganisms under controlled conditions for industrial bioprocessing. They maintain sterility and allow precise regulation of pH, temperature, oxygen, and nutrient levels to optimize microbial growth and metabolite production. Bioreactors range from small laboratory units of 1 liter to industrial systems holding up to 500,000 liters, though only about 75% of their volume is actively used for fermentation. The remaining headspace...
01:30Microbial Wastewater Treatment
Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
01:18Bioreactor Controls-II
In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the fermentor via a sparger...
01:27Upstream Processing
Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...
01:14Batch vs Continuous Culture
Fermentation is a foundational biotechnological process used to produce pharmaceuticals, biofuels, enzymes, and food additives. Among industrial strategies, batch and continuous fermentation are the two most widely applied. Although both rely on microbial conversion of substrates into desired products, they differ markedly in operation, productivity, and suitability for specific applications.Batch fermentation occurs in a closed system in which nutrient media and inoculum are added at the...
