Research on flocculation conditions and coking wastewatertreatment of Microbial Flocculants

Wei Xiaojin,Li Jing,He Xuwen

Strategic Study of CAE 2009, Volume 11, Issue 2,   Pages 88-91

Abstract:

One strain of Bacillus SP. from the activated sludge is able to produce a stable and efficient bio- flocculation. The flocculation properties and application of this microbial flocculants in wastewater treatment are studied. The results show that the optimum flocculation can be reached in conditions as follows: above pH 7.0, the dosage of coagulation aid CaCl2 is 5.0 % , the flocculants dosage is 0.2 % , and the centrifugal condition of flocculants broth is 4 000 r/min min and last for 30 min. In the optimum flocculation condition the strain boasts obvious coagulation efficiency in wastewater treatment with produced bio- flocculation.

PVDF ultrafiltration membranes of controlled performance via blending PVDF-g-PEGMA copolymer synthesized

Shuai Wang, Tong Li, Chen Chen, Baicang Liu, John C. Crittenden

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 2, doi: 10.1007/s11783-017-0980-0

Abstract: Polyvinylidene fluoride grafted with poly(ethylene glycol) methyl ether methacrylate (PVDF-g-PEGMA) was synthesized using atomic transfer radical polymerization (ATRP) at different reaction times (9 h, 19 h, and 29 h). The corresponding conversion rates were 10%, 20% and 30%, respectively. PVDF was blended with the copolymer mixture containing PVDF-g-PEGMA, solvent and residual PEGMA under different reaction times. In this study, we explored the effect of the copolymer mixture additives with different synthesis times on cast membrane performance. Increasing the reaction time of PVDF-g-PEGMA causes more PVDF-g-PEGMA and less residual PEGMA to be found in the casting solution. Incremental PVDF-g-PEGMA can dramatically increase the viscosity of the casting solution. An overly high viscosity led to a delayed phase inversion, thus hindering PEGMA segments in PVDF-g-PEGMA from migrating to the membrane surface. However, more residual PEGMA contributed to helping more PEGMA segments migrate to the membrane surface. The pure water fluxes of the blended membrane with reaction times of 9 h, 19 h, and 29 h are 5445 L·m ·h , 1068 L·m ·h and 1179 L·m ·h , respectively, at 0.07 MPa. Delayed phase inversion can form smaller surface pore size distributions, thus decreasing the water flux for the membranes with PVDF-g-PEGMA at 19 h and 29 h. Therefore, we can control the membrane pore size distribution by decreasing the reaction time of PVDF-g-PEGMA to obtain a better flux performance. The membrane with PVDF-g-PEGMA at 19 h exhibits the best foulant rejection and cleaning recovery due to its narrow pore size distribution and high surface oxygen content.

Power to gas: addressing renewable curtailment by converting to hydrogen

Xiaohe YAN, Xin ZHANG, Chenghong GU, Furong LI

Frontiers in Energy 2018, Volume 12, Issue 4,   Pages 560-568 doi: 10.1007/s11708-018-0588-5

Abstract: Renewable energy is the key to meeting increasing electricity demand and the decarburization targets in the generation mix. However, due to constrained power network capacity, a large volume of renewable generation is curtailed particularly from wind power, which is a huge waste of resources. There are typically three approaches to addressing excessive renewable: direct curtailment, the reinforcement of networks to expand transfer capacity, and the conversion of excessive renewable into other energy types, such as hydrogen, to transport. The costs and benefits of the three approaches could vary significantly across location, time, and penetration of renewable energy. This paper conducts a cost-benefit analysis and comparison of the three techniques to address wind curtailment. It uses a reduced 16-busbar UK transmission network to analyze the performance of the three approaches. The UK 2020 generation mix is used to quantify the saved renewable energy and incurred costs. The payback time and net present value of the two investment techniques are compared. From demonstration, it is reasonable to conclude that converting excessive wind power into hydrogen to transport is an environmentally friendly and cost-effective way to address wind curtailment.
