Abstract:
The persistence of homological features in simplicial complex representations of big datasets in R n resulting from Vietoris–Rips or Čech filtrations is commonly used to probe the topological structure of such datasets. In this paper, the notion of homological persistence in simplicial complexes obtained from power filtrations of graphs is introduced. Specifically, the r th complex, r ≥ 1, in such a power filtration is the clique complex of the r th power G r of a simple graph G . Because the graph distance in G is the relevant proximity parameter, unlike a Euclidean filtration of a dataset wh

Abstract:
Multimodal zeta potential distribution in chemical birch pulp process water was studied by filtrating the water into fractions and subsequently measuring zeta potential, charge quantity, turbidity and organic substances. Filtrations were made using 12 μm, 1.6 μm, 1.2 μm, 0.45 μm and 0.1 μm membranes. The number of populations with different zeta potentials diminished with filtration. With the unfiltrated water, 12 μm and 1.6 μm filtrates, three or four different zeta potentials were observed. When the filtration was performed with a 1.2 μm membrane or smaller, only two populations of different

Abstract:
A pressure filtration–flocculation–solidification combined treatment possesses great potential for the reutilization of the waste mud slurry generated from diverse construction projects as filling material due to its versatility and high efficiency. However, very limited existing studies have focused on the factors affecting pressure filtration’s efficiency. In this paper, a calculation model for compression filtration is established based on laboratory pressure filtration model tests and one-dimensional large-strain consolidation theory.

Abstract:
Spinning effluents (SE) from dry-spun acrylic fiber producing are hard to biodegrade for dimethyl formamide (DMF) and nitriles contained. Integrated membrane filtrations including micro-filtration (MF), ultra-filtration (UF) and nano-filtration (NF) were adopted to separate the pollutants in SE. Experiment showed that MF has weak capacity for the removal of organic pollutants, while NF and UF contributed to 49.49% and 31.51% to the initial COD removal rates of SE.

To provide safe and clean water for a variety of purposes, water filtration is essential. Traditional filtration materials, while effective, often pose environmental concerns due to their non-biodegradable nature. In recent years, biodegradable polymers have emerged as a promising alternative in the field of water purification. This manuscript provides a comprehensive overview of biodegradable polymers used in water filtration, emphasizing recent advancements and applications.

Abstract:
The space of homomorphisms between a projective object and a Verma module in category $\mathcal O$ inherits an induced filtration from the Jantzen filtration on the Verma module. On the other hand there is the Andersen filtration on the space of homomorphisms between a Verma module and a tilting module. Arkhipov's tilting functor, a contravariant self-equivalence of a certain subcategory of $\mathcal O$, which maps projective to tilting modules induces an isomorphism of these kinds of Hom-spaces. We show that this equivalence identifies both filtrations.

Abstract:
The simple operational and maintenance requirements of slow sand filtration (SSF), coupled with its high biological treatment efficiency makes it an attractive technology. The main limitation of SSF is its vulnerability to high suspended solids loadings. Pre-treatment in such instances can be achieved by gravel filtration. Cases of gravel pre-filtration underperformance have been attributed to significant fractions of influent suspended particles in the colloidal range. Maximum limits of turbidity for the application of gravel pre-filters have also been suggested. A simple intervention to over

Abstract:
<p>Cake filtration is a unit operation to separate solids from fluids in industrial processes. The build up of a filter cake is usually accompanied with a decrease in overall permeability over the filter leading to an increased pressure drop over the filter. For an incompressible filter cake that builds up on a homogeneous filter cloth, a linear pressure drop profile over time is expected for a constant fluid volume flow. However, experiments show curved pressure drop profiles, which are also attributed to inhomogeneities of the filter (filter medium and/or residual filter cake).</p><p>In this

Abstract:
Slow sand filtration requires low turbidity water for effective operation. In most cases this means pretreating the raw water to reduce its turbidity. Lately horizontal gravel filters have become very popular as a means of pretreatment. They are simple to operate, have a large mass storage capacity, and can cope with high turbidity shock loads. However, cleaning them can be a problem. An alternative pretreatment, which this study is concerned with, is upflow sand roughing filtration. It has the potential advantages of simple design, ease of operation and cleaning, and low area requirements. A

Abstract:
Up to date, sludge filterability has been characterized by the Ruth&rsquo<br>s classical filtration theory and quantified by the well-known parameter specific cake resistance (SCR). However, the complexity of the actual phenomenon is clearly underestimated by the classical filtration theory and SCR is often not satisfactory in describing filterability. Although many scientific studies were conducted for a better analysis and understanding of the filtration theory, still a practically applicable solution to replace the classical theory for a better description of filterability has not been prop

Fouling of filter media and physico-chemical properties of suspensions decrease the efficiency of filtration devices in a wide range of process industries. Environmental protection causes increasing demand to clean effluent waters to higher standards and to recycle process waters more completely. Conventional deliquoring processes are mainly based on a single driving force, usually gravity, underpressure or pressure. Today, multiforce deliquoring processes based on a combination of ultrasonic and/or other nonmechanical forces, like an electric field, are being developed. These new technologica
