What is MBBR in water treatment?
When the waste water is compatible with a biological treatment and the content of organic matter is high, MBBR is beyond doubt the most efficient option. This technology consists of the growth of biomass as a biofilm on plastic supports that are continuously moving in the biological reactor. These supports have a high specific area per unit of volume, which allows more biomass to flow per unit of volume than in conventional reactors. MBBRs do not have the bed clogging problems due to excessive biomass growth as occur in fixed bed systems and the system is considerably more efficient compared to a conventional system because the biofilm that forms on the walls of the support is more effective than biological flocculants. Considering that the support’s particles have a high specific area, MBBR reactors are also much smaller than those using activated sludge. Another additional advantage is that the process can be divided into various stages with a specific biomass growing in each, adapted to the pollutant load in the feed current. This flexibility allows more persistent compounds to be broken down. This technique is viable only when the pollution is biodegradable.
What are the substances in wastewater?
Generally, these wastewater contain: A high content of organic matter, a large part of which is easily biodegradable (alcohol, acetone, etc). Slowly biodegradable organic compounds and refractory substances (aromatic compounds, chlorinated hydrocarbons, etc). Inhibiting and toxic compounds (antibiotics). Soaps and detergents with surfactants.
What is wastewater treatment in pharmaceutical industry?
Wastewater treatment in pharmaceutical industry. Pharmaceutical industry wastewater varies enormously in flow and composition, depending on factors such as the production rate, the specific preparation being carried out, which activities are generating the waste water, etc.
What is advanced oxidation?
Advanced oxidation refers to a wide range of technologies most of which are based on generating hydroxyl radicals or on supplying the energy needed to destroy the polluting molecule. These techniques are especially competitive for eliminating halogenated hydrocarbons (benzene, toluene, phenol, etc), detergents, dyes, etc.
Is MBBR reactor smaller than activated sludge?
Considering that the support’s particles have a high specific area, MBBR reactors are also much smaller than those using activated sludge. Another additional advantage is that the process can be divided into various stages with a specific biomass growing in each, adapted to the pollutant load in the feed current.
Is activated sludge biodegradable?
Although this is the most competitive process for waste water with easily biodegradable organic matter, because of the possible presence of inhibiting and toxic compounds for the biomass and the low biodegradability of some effluents produced, it is not the most recommendable process.
Is vacuum evaporation a viable process?
When a biological process is not viable, vacuum evaporation is a robust, efficient, versatile and competitive option. Despite their high efficiency and non-selectivity, advanced oxidation techniques are reserved for applications in which the flow to be treated is low, due to the cost involved.
