The removal efficiency and mechanism of microplastic enhancement by positive modification dissolved air flotation

Water environment research, 2020
Microplastics (MPs) are widely distributed in freshwater and have the following characteristics: small size, strong hydrophobicity, difficult degradation, and easy adsorption of toxic substances.

Pathway, classification and removal efficiency of microplastics in wastewater treatment plants.

Environmental Pollution, 2019
Microplastics (MPs) contamination in water environment has recently been documented as an emerging environmental threat due to their negative impact on the ecosystem. Their sources are many, but all of them are from synthetic materials.

Influence of fiber diameter, filter thickness, and packing density on PM2.5 removal efficiency of electrospun nanofiber air filters for indoor applications

, 2020
Electrospinning is a versatile technique to fabricate nanofiber filters with high PM2.5 removal efficiency and relatively low pressure drop. The eletrospun nanofiber filters may therefore be applied in buildings to reduce indoor exposure to PM2.5 and the

Co-culturing microalgae with endophytic bacteria increases nutrient removal efficiency for biogas purification.

Bioresource Technology, 2020
Endophytic bacteria were isolated from Chlorella vulgaris and co-cultured with its host microalgae to determine whether this symbiotic system is suitable for purifying biogas and biogas slurry.

Intensification of a new electrocoagulation system characterized by minimum energy consumption and maximum removal efficiency of heavy metals from simulated wastewater

Chemical Engineering and Processing, 2020
In the present study, a new simple self-gas stirred batch electrocoagulation reactor was designed. The new cell consisted of a cylindrical Al sheet anode and a cylindrical Al screen cathode placed at a small distance from the anode.

Modeling of a full-scale sewage treatment plant to predict the nutrient removal efficiency using a long short-term memory (LSTM) neural network

, 2020
A long short-term memory (LSTM)-based neural network was proposed and developed to predict the ammonium (NH4-N), total nitrogen (TN), and total phosphorus (TP) removal efficiency of an anaerobic-anoxic-oxic membrane bioreactor (A-A-O MBR) system after ...

Efficient and Robust Specular Highlight Removal

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2015
A robust and effective specular highlight removal method is proposed in this paper. It is based on a key observation--the maximum fraction of the diffuse colour component in diffuse local patches in colour images changes smoothly. The specular pixels can thus be treated as noise in this case.

Charged graphene aerogel filter enabled superior particulate matter removal efficiency in harsh environment

, 2020
Fine particles pose a dangerous threat to our environment and human health. Although a series of air filters have been developed, to achieve high removal efficiency while maintaining a low pressure drop is still a challenging task.

Software defect-removal efficiency

Computer, 1996
Defect-removal efficiency-the percentage of bugs eliminated by software reviews, inspections and tests-is a powerful software quality metric that should be understood by everyone in the software business. Many top companies have used this metric since the 1960s.

Efficient removers for poly(methylmethacrylate)

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2002
As nanotechnology approaches molecular scales, issues of surface contamination by unremoved resists will play an important role in device fabrication. Electron beam lithography of polymethylmethacrylate (PMMA) resist is still among the most widely used nanofabrication techniques, so it is relevant to study its residual contamination on both exposed and
