Abstract:

Indoor air quality is particularly important not only in schools, hospitals, nursing homes and other environments that accommodate sensitive people, but also in production places with high cleanliness requirements. At present, most researches are aimed at testing the mass concentration of contaminants and there are few characterizations of the release characteristics(that is, the release rate) of contaminants. Air pollutants are generally include particulate contaminants and gaseous contaminants. This paper takes cigarettes as typical representatives of particulate contaminants and takes the s

Abstract:

The potential for transport of bacteria by groundwater in fractured crystalline rock was assessed in a series of field-scale tracer tests. The breakthrough curves for injected Escherichla coll and “non-reactive” particle tracers were compared with those for conservative inorganic and radioactive tracers. Rapid transport, relative to the conservative tracers, of both bacteria and non-reactive particles was observed. The first appearance of both was with, or slightly before, the conservative tracers for water movement. Removal of the bacteria and particles by filtration processes occurred and wa

Abstract:

Since the major part of the contaminants in municipal wastewater is associated with particles, direct particle separation is an effective way of lowering the wastewater contaminant level. An additional biological oxidation is usually required to remove the residual soluble contaminants. This paper presents the experimental data on the chemical treatment of municipal wastewater by the Jet Mixed Separator(JMS) which can be used as a unit process for physico-chemical treatment. As simultaneous flocculation and sedimentation occurred, the JMS effluent concentration of phosphorus and suspended soli

Abstract:

Contaminants in the interstitial waters are not only dissolved but also associated with a filterable colloidal phase such as DOC. The DOC plays an important role regulating the distribution of chemicals between particulate and dissolved phases since it binds chemicals and makes them unavailable for vertical diffusive exchange. A three-phase partitioning model that consists of free-dissolved, DOC-bound, particulate-bound components of the chemicals involved is used for the contaminant transport model in order to include the effect of DOC on the partition coefficient.

Abstract:

The products or the process of production are susceptible to contamination in the environment. In this regard, the manufacturing of semiconductors and their related applications play a significant role. The airborne concentration of particulates like chemical vapors or dust compounds can be found even in an enclosed environment. This accounts for pollution in cleanrooms for biomedical applications. The rooms should be monitored and protected from harmful substances and contamination risks. In this work, the room is cleaned with nano-particulate filters to eliminate the dust entering the room.

Abstract:

One of the major health risks for humans, especially for those living in large cities, is air pollution. Air pollution consists mainly of emissions of particulate matter (PM), nitrogen oxides, sulphur dioxide, ammonia and volatile organic compounds (VOCs). The organic carbon fraction of particulate matter is a mixture of hundreds of organic compounds, such as polycyclic aromatic hydrocarbons (PAHs), or polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), some of which are mutagenic and/or carcinogenic. Because this particulate matter represents a serious threat for human health, meas

Abstract:

Contaminants in hydraulic and lubricating oils are harmful to lubrication. Therefore, contamination control of hydraulic and lubricating oils has been implemented in many factories and oil cleanliness standards of hydraulic and lubricating oils have been established as criteria for oil contamination control. There are two types of oil cleanliness standards: one is based on particle count and the other on gravimetric analysis. NAS 1638, ISO 4406, SAE AS4059, and JISB9930 belong to the former and ASTM D4898 and JISB9931 to the latter. The par tide count defines oil cleanliness by counting the nu

The problem of dispersion and flushing of contaminants from estuarine waters is of ever-increasing importance to engineers. To determine this reduction in concentration and removal of contaminants from estuarine water, several basic methods have been established. They are: (1) the classical tidal prism method, where the flushing is a function of the amount of water brought in and removed on each tide; (2) Ketchum's modified tidal prism method, where flushing is a function of tidal action and river discharge; and (3) a diffusion-advection method which may be based on a coefficient of eddy diffu

Small airborne particulate contaminants such as mould spores can harm human health by causing or exacerbating respiratory illnesses. Such particulates tend to be microscopic; however, in the case of moulds, contamination can be associated with visible colonial growth on surfaces and musty odours detectable by occupants of the room. Shared spaces, such as offices and classrooms, represent areas of higher risk due to the larger numbers of people being exposed to airborne particulates.

Abstract:

A paucity of literature has compared geotextile dewatering methods to more conventional dewatering methods (i.e., centrifuge, sedimentation) in the context of how geotextile dewatering performs at reducing particulate matter in dewatering effluent. Particulate matter is the primary source of inorganic and organic contaminants (i.e., dioxins and furans) in an unconsolidated sediment (estimated 577 000 m3) that has accumulated in a wastewater stabilization basin in Nova Scotia, Canada. Physical and chemical properties of contaminated sediment were initially characterized, and subsequent laborato

Abstract:

The following should be considered when installing and maintaining a drip irrigation system for vegetable crops: water source (surface or ground water); water quality (salinity, particulate matter, contaminants); size of area to be irrigated; pump size; soil type; drip tape type; crop to be irrigated; management skill of the operator; automation needs; water meter and budget. Use a professional designer.

Abstract:

A low cost, compact, real-time, and quick measurement optical device based on the absorbance of white light, which comprised of photodiodes in a 3-element color-sensor, feedback diodes, water and temperature sensing element, and so on, was developed and tested in low absorption mineral oil. The device, a deviation from conventional electrical, mechanical, and electrochemical techniques, uses color ratio (CR) and total contamination index (TCI) parameters based on transmitted light intensity in RGB wavelengths for oil condition monitoring. Test results showed that CR corroborated CIE chromatici

Abstract:

ABSTRACTContamination of snow cover has been investigated in the Longyearbyen (78°13 N, 15°38 E) and Barentsburg (78°3 N, 14°12 E) areas, which are situated in the southwest part of Spitsbergen (Svalbard archipelago). Snow cover was sampled in two winter seasons, 2012–2013 and 2013–2014, at 54 locations within potentially contaminated areas. Sampling incorporated the whole snow mass and was combined with morphological observations as well as thickness and density measurements. Meltwater and suspended solids were further analysed for a wide range of contaminants including polycyclic aromatic hy
