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...

Moving bed biofilm reactor (MBBR) is considered as a promising technology for wastewater treatment owing to the high biomass retention and low cost. In this study, performance of using MBBR partial denitrification (PD) was investigated. Denitrifying successfully formed after 40 days with nitrite reduction rate 40.83 mg VSS/g carriers 51.52 N/(gVSS·h), respectively. Morphology analysis by scanni...

Abstract In recent days, the waste productions from industries are increased and direct discharge of wastes causes various pollution to environment. Wastewater treatment in textile dye industry mainly involves highly colored wastewater containing variety dyes different concentrations. The dyeing using types pigments concentration during their several production steps. These a which contains org...

A laboratory-scale pilot plant of moving bed biofilm reactor coupled with membrane bioreactor (MBBR-MBR) was studied regard to wastewater treatment in the textile industry, and reuse feasibility treated water investigated. The comprised two connected parts: an aerobic tank filled carriers a submerged tank. MBBR-MBR system reduced hydraulic retention time 1 day, which is very promising compared ...

Nghiên cứu nhằm đánh giá hiệu quả xử lý nước thải sinh hoạt bể phản ứng thể di động (Moving bed biofilm reactor - MBBR) kết hợp với cột màng lọc tự chế ở những thời gian lưu khác nhau. Bể MBBR có tích 45,54 L chứa 40% K3, và quy mô phòng thí nghiệm được sử dụng trong nghiên cứu.

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...

Background and purpose: The performance of full-scale moving bed biofilm reactor (MBBR) was evaluated as an alternative for upgrading of Kish Island Mirmohana wastewater treatment plant. In this study activated sludge process upgrade to MBBR process and different operating parameters were compared. Materials and Methods: Effect of upgrading on different parameters such as organic loading rate (...

Nowadays formaldehyde is used as raw material in many industries. It has also disinfection applications in some public places. Due to its toxicity for microorganisms, chemical or anaerobic biological methods are applied for treating wastewater containing formaldehyde.In this research, formaldehyde removal efficiencies of aerobic biological treatment systems including moving bed biofilm (MMBR) a...
