Moving Bed Biofilm Reactor Performance in Phenol Removal from Wastewater
Background: Phenolic compounds are found in wastewater of many industries such as pulp and paper, textile, petrochemical, oil refineries, production of phenolic resins, plastics, coal furnace, tannery, rubber reclamation plant, fertilizers, coke, paints, rubber, decolorizer, resins, rubber and phenol- formaldehyde resin industries. This study aimed to evaluate Moving Bed Biofil...
متن کاملThe Moving Bed Biofilm Reactor
A new biofilm reactor for wastewater treatment, the moving bed biofilm reactor (MBBR), is discussed. A general description of the reactor is given. Results from investigations of different applications (carbonaceous removal, nitrification and nitrogen removal) when used for municipal wastewater treatment, are discussed. Design values are given and it is demonstrated that use of this reactor res...
متن کاملسینتیک واکنش تصفیه فاضلاب حاوی آنیلین در راکتور بیوفیلمی با بستر متحرک
Background and Objectives: Experiments were conducted to investigate the behavior of Moving Bed Biofilm Reactor (MBBR) as a novel aerobic process for treatment of aniline synthetic wastewater as a hard biodegradable compound is commonly used in number of industrial processes. The objective of this paper is evaluation of MBBR in different conditions for treatment of aniline and determination of ...
متن کاملSimultaneous Removal of Perchlorate and Nitrate Using Biodegradable Polymers Bioreactor Concept
Simultaneous perchlorate and nitrate removal from contaminated groundwater in one reactor has been realized with different methods in the past. The usage of biodegradable polymers as biofilm carriers and carbon source is new. Polymer in this paper was designed out of the copolymer of starch and polyvinyl alcohol. Under polluted water with 2 mg/L of perchlorate and 20 mg/L of NO3-N, it was possi...
متن کاملBiodegradable polymers as solid substrate and biofilm carrier for denitrification in recirculated aquaculture systems
A simple process for nitrate removal is proposed for its application in aquaculture. Biodegradable polymer pellets are acting as solid substrate and biofilm carrier for denitrification. Laboratory experiments with conventional aquaria and fish were used to examine the feasibility and a first evaluation of the process performance in a recirculated aquaculture system. All over the test-period the...
