Treatment of dairy wastewater with a membrane bioreactor
In this study, an aerobic submerged membrane bioreactor (sMBR) was used for the treatment of dairy wastewater at 15 h of hydraulic retention time (HRT) and 40 d of sludge retention time (SRT)
Abstract. In this study, an aerobic submerged membrane bioreactor (sMBR) was used for the treatment of dairy wastewater at 15 h of hydraulic retention time (HRT) and 40 d of sludge retention time (SRT) with constant permeate flux (9.5 L.m-3.d-1 (LMH)). The COD, ammonia-nitrogen (NH 3-N) and orthophosphate (PO 4-P) removal efficiencies were 98.2%, 95.4% and 88.9%, respectively.

Treatment of Dairy Wastewater with a Membrane Bioreactor 761 Brazilian Journal of Chemical Engineering Vol. 30, No. 04, pp. 759 - 770, October - December, 2013 was stored in the feed tank and discharged by gravity to the biological tank, where a float valve controlled
In this study, an aerobic membrane bioreactor (MBR) was used for the treatment of wastewater from a large dairy industry and two hydraulic retention times (HRT), 6 and 8 hours, were evaluated. For both HRTs removal efficiencies of organic matter of 99% were obtained. Despite high permeate flux (27.5 L/h.m虏), the system operated fairly stablely.
Evaluation of a membrane bioreactor on dairy wastewater
However, the most commonly applied wastewater post-treatment or tertiary treatment processes nowadays for water reuse at the dairy industries consist of chlorination and UV disinfection and not membrane filtration processes (Chowdhury, 2014, Hai et al., 2014).

- What are cationic polyacrylamide copolymers?
- Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
- Are cationic polyacrylamide copolymers harmful to the environment?
- Environ Sci Eur. 2018; 30 (1): 16. Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (cPAM), a linear water-soluble and high-molecular polymeric compound with cationic charges, can effectively enhance solid-liquid separation through charge neutralization and interparticle bridging and is widely used worldwide ( Campos et al., 2008; Dai et al., 2014).
- Do cationic polyacrylamide copolymers degrade in soil after land-spreading?
- This project demonstrated that the synthetic cationic polyacrylamide copolymers (PAMs) incorporating C–C-bonds in the main chain slowly degrade in soil after land-spreading as a component of MWWTP sludge.
