The presence of particles such as algae, clay, organic materials and water-soluble substances often create turbidity or color in water. In recent years, electrocoagulation process has attracted an extensive attention due to its advantages. Since sand filters are widely used in water treatment industry and their corresponding backwash water is large in volume, turbidity removal will save water c...

Sand dripping in 1 dimensional Sand Pile Model is rst studied. Patterns and signals appear. Their behaviors and interactions are explained and asymptotic approximations are made. The total collapsing time of a single stack of sand is linear in function of the number of grains.

The increasing demand and exorbitant use of river bed sand in foundries over the years have led to its depletion at an alarming rate. Consequently, many states India imposed severe restrictions on mining riverbed sand. Therefore, effort is made explore potential sea for cast iron foundry applications. Experiments were performed optimizing composition molding with respect functional properties n...

Magnetite is a type of iron ore and a valuable commodity that occurs naturally in black sand beaches in the Philippines. However, black sand mining often takes place illegally and increases the likelihood and magnitude of geohazards, such as land subsidence, which augments the exposure of local communities to sea level rise and to typhoon-related threats. Detection of black sand mining activiti...

the effects of waterlogging, sewage sludge and animal manure on the concentrations of dtpa extractable copper, iron, manganese and zinc were investigated in two different types of soil. a factorial experiment based upon a completely randomized design of two replications containing duration of waterlogging at six levels (0, 1, 3, 7, 15, 30 days), source of organic fertilizer at three levels (con...

Iron deficiency anemia (IDA) is a health problem in Indonesia. Prevention and treatment of IDA carried out by giving fortified foods oral iron therapy. Both can use ferrous fumarate which made with reacting bivalent disodium fumarate. Bivalent be obtained from sand This study aims to synthesize Indonesian sand, Malang, Sukabumi, Cianjur area, determine its absorption through vivo body weight ga...

The typical time-dependent decrease of the iron corrosion rate is often difficult to consider while designing Fe0-based remediation systems. One most promising approaches amendment with manganese dioxide (Fe0/MnO2 system). resulting system a very complex one where characterization challenging. present communication uses methylene blue discoloration (MB method) characterize Fe0/MnO2 system. Shak...

The purpose of this study was to evaluate the production feasibility of triaxial whiteware using sand from cast iron moulds as a raw material instead of silica, and recycled glass in place of feldspar. Formulations were prepared using sand, glass waste, and white-firing clay such that only 50% of the composition was virgin material (clay). The ceramic bodies were formed by pressing and fired at...

Understanding the interaction between bacterial cells and solid surfaces is essential to our attempts to quantify and predict the transport of microbes in groundwater aquifers, whether from the point of view of contamination or from that of bioremediation. The sorption of bacterial cells suspended in groundwater to porous medium grains was examined in batch studies. Bacterial sorption to clean ...
