Leaching
Leaching is a solid-liquid extraction process where one or more constituents of a solid mixture are separated by contact with a liquid solvent. It works on the principles of solvent penetrating the solid, the solute then diffusing through the solid-solvent mixture to the particle surface until equilibrium is established. There are two types - unsteady state processes like in situ leaching and heap leaching, and steady state processes using agitated vessels or continuous countercurrent decantation. Various equipment is used for leaching like percolation tanks, shank systems, agitated column vessels, thickeners, hydrocyclones, and various extractors.

Evaporation ppt
Evaporation is a separation process where a solvent is vaporized from a solution to concentrate it. There are several types of evaporators used in evaporation, including horizontal tube evaporators, vertical tube evaporators, and climbing film evaporators. Multiple effect evaporators can reuse vapor from one effect in the next to improve heat economy. Evaporation finds applications in industries like sugar production, dairy processing, fertilizer production, and petroleum refining to separate and concentrate components.
Chemical oxygen demand
Chemical oxygen demand (COD) is a measure of the oxygen-consuming capacity of inorganic and organic matter in water. COD determines the amount of oxygen required to oxidize organic compounds and inorganic matter in water. There are two main methods to measure COD - the open reflux method and closed reflux method. The open reflux method involves refluxing the sample and dichromate solution for 2 hours, then titrating the remaining dichromate with ferrous ammonium sulfate to determine COD concentration in mg/L. A high COD means more oxidizable organic material is present in water, which can reduce dissolved oxygen and harm aquatic life. COD is useful for assessing waste strength and effects on receiving environments
Bollman extractor
The document describes the Bollman extractor, which is a type of basket extractor used for leaching solids. It consists of a vertical chamber with a series of perforated baskets attached to a chain conveyor. Dry solids are added to the top baskets and leached by a solvent solution as the baskets descend counter-currently. The wet solids are removed at the bottom and the recovered solvent is evaporated and stripped to extract oil. The Bollman extractor provides continuous counter-current contact between solids and solvent for effective leaching.

Electrodialysis
This document describes the process of electrodialysis, which uses an electrical current to transport ions through ion exchange membranes to separate salts from water. Key components include a power source, electrodes, and ion exchange membranes arranged alternately. The process results in one compartment becoming depleted of ions and adjacent compartments becoming enriched. It is commonly used for desalination of water and process solutions, with advantages of low energy use, high conversion ratio, and ability to concentrate brine. Applications include treatment of brackish water, boiler feedwater, wastewater, and industrial streams.

Water 101: An Introduction to the Properties of Water
It reasonably can be argued that that most participants in the roofing, building and design trades tend to either take water for granted or lack the basic understanding of both the chemistry and physics that play such a large role in water accumulation within a building enclosure. Sure, people in the construction business fear the effects of excess water, but few have taken the time to understand why it acts the way it does.
The driving forces that cause moisture movement are fundamental properties of nature; therefore, preventing water infiltration and resulting damage at the typical building project requires close attention during the design and construction processes to all potential moisture sources and routes.
Seven fundamental aspects of water are presented in Water 101 to provide Trinity | ERD forensic personnel and our clients an essential knowledge base for the physical properties of water.

The study is aboutthe use and comparison of three non-destructive methods (dynamic auscultation, sclerometric auscultation and auscultation by RADAR (Radio Detecting and Ranging) to monitor and assess the quality of concrete. Samples of reinforced concrete panels, dimensions 200x100x30 cm of concrete dosed at 350 kg/m3 with diverse E/C ratio were achieved, conserved in the laboratory and subjected to various non-destructive test. The synthesis of the results obtained by auscultation RADAR shows a decrease in the propagation speed of the electromagnetic wave with an increase of the E/C ratio and a decrease in resistance of concrete values measured and confirmed by other non-destructive techniques (sclerometric and dynamic auscultations). This shows that more the dielectric constant is high, morethe concrete resistance is reduced, and conversely the opposite.

Effect of boron content on steels and recommended practice for welding Sasank...NSW Environment and Planning
Boron content affects steel properties. In low concentrations, boron improves hardness and impact properties but higher amounts decrease ductility and weldability. Standards regulate acceptable boron ranges which are lower for carbon steels compared to quenched and tempered steels. When welding higher boron steels, preheat and interpass temperatures must be controlled to slow cooling rates and prevent martensite formation. A case study describes a mining excavator repair where visual inspection informed the repair strategy, edges were prepared, and welding parameters were developed and followed to achieve an effective repair with ultrasonic testing and inspections ensuring quality and safety.Unit 5 Nanomaterials and Nanotechnology - 1.pptx

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
