Tracking Inorganic Solids in Biological Enhanced Phosphorus Removal Wastewater Treatment Systems
The modelling and tracking of solids in wastewater treatment plants (WWTPs) has historically been focussed on the different types of organic solids. Conversely, there is currently limited information on the composition of inorganic solids, and how they behave across different WWTP unit operations. …

The Effects of Inorganic Solids and Certain Gases on the Thermal Decomposition of Catechol
… biomass. Calcium carbonate and iron oxide are inorganic components of coal and wood, which have demonstrated catalytic properties in thermal reactions and are commercially used to enhance the conversion of solid fuels. In this study, the effects of the inorganic solids on pyrolysis and …

High-Resolution Multinuclear Magnetic Resonance of Inorganic Solids. Oxygen-17 Nuclear Magnetic Resonance Studies of Inorganic Oxides, Oxyanions, and Silicates
High resolution (8.45 and 11.7 Tesla) oxygen-17 NMR spectra have been obtained for a variety of oxides, oxyanions, carbonyls and for crystals and glasses in the system CaO-MgO-SiO(,2) using magic-angle sample spinning (MASS) and variable-angle sample spinning (VASS) techniques. The results …

Synthesis, Structure, and Characterization of Hybrid Solids Containing Polyoxometalates and Ruthenium Polypyridyl Complexes
<p>Polyoxometalates (POMs), which are inorganic metal oxide cluster anions with discrete structures, have been extensively studied in recent years due to their large variety of applications such as medicine, biology, catalysis, material sciences and chemical analysis. Ruthenium polypyridyl …

Development of a headspace solid-phase microextraction (HS-SPME) procedure for the determination of short-chain fatty acids (SCFAs) in activated sludge by GC-FID
… of wastewater treatment includes the removal of inorganic solids such as sand and gravel as well as organic materials, phosphorus, and nitrogen. Activated sludge, containing a variety of living organisms, is added into the wastewater treatment system. Short-chain fatty acids (SCFAs), an energy …

Influence Of Suspended Particle Size And Composition On Particle Image Processing, Estuarine Floc Fractal Properties, And Resulting Estuarine Light Attenuation
… sediment grains, but rather are clusters of inorganic and organic components known as flocs. Because of their fragile nature, flocs are challenging to observe in-situ, so their influence on the optical properties of the system are not well-known. This dissertation used a combination of …

Design of a Nutrient Reclamation System for the Cultivation of Microalgae for Biofuel Production and Other Industrial Applications
… An ultrafiltration system was used to remove inorganic solids and biological contaminants from wastewater taken from a swine farm in Savoy, Arkansas. The permeate from the system was then used as the nutrient source for the cultivation of the marine microalgae Porphyridium cruentum.</p> …

Establishing scale inhibitor retention mechanisms in pure adsorption and coupled adsorption/precipitation treatments
… and efficient ways for preventing formation of inorganic solids deposition such as carbonate and sulphate scales in reservoir and near wellbore formation is by applying scale inhibitor (SI) squeeze treatments. The two main mechanisms that govern the scale inhibitor retention and release process …
