Water and wastewater treatment for Solar industry
Solar cells arc manufactured in a complex process thai requires enormous know-how. The objective is to produce panels with a high level of efficiency at low cost. To achieve this, different production processes are used. A fundamental distinction is made between solar cells on the basis of silicon wafers and thin-film cells, in which a special process is used to apply the photovoltaic layer onto ...

How big is the distributed energy opportunity for water and wastewater utilities?
Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of annual ...

Multi-criterion optimization of energy management in drinking systems
In this study, two different energy sources that are connected to a pumped storage water supply system are analyzed: a water and a wind turbine. A water turbine can be integrated in a water supply system in high-pressure locations. Recently, new sources of energy production are being researched and applied due to the increase in the price of conventional energy sources and concerns regarding the ...

TOC Analysis for Standard Methods 5310B: High-Temperature Combustion Method
Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a sample ...

Isotherm models and kinetics of copper adsorption by using hydrochar produced from hydrothermal carbonization of faecal sludge
Low cost adsorbents have been extensively reported for use as a promising substitution for commercial adsorbents for pollutant removal in water and wastewater treatment. In this study, hydrochar produced from the hydrothermal carbonization (HTC) of faecal sludge (FS) (called HTC-hydrochar) was further chemically modified with KOH (called KOH-hydrochar) to improve its surface functional ...

Sorption of cadmium in columns of sand-supported hydrothermally carbonized particles
Sanitation in urban slums, especially in countries in Sub-Saharan Africa, is a challenge. One of the solutions to sanitation is to valorize waste, and to convert bio-waste present in the slum in a cheap and affordable way into lignite via hydrothermal carbonization (HTC). HTC is simple, cheap, converts all carbon (100%), eliminates pathogens completely, and requires wet starting ...

Microbiotests for the Evaluation of the Pollution from the Oil Shale Industry
Abstract : In this study a comparative chemical and toxicological analysis of 8 phenolic river water and wastewater samples originating from the Kohtla-Järve oil shale industry region (north-western part of Estonia) was made. The total phenolic content of the samples ranged from 0.01 to 195 mg/l. For 5 wastewaters the corresponding synthetic phenolic analogues were prepared. A battery of ...

Modelling anaerobic digestion of concentrated black water and faecal matter in accumulation system
A dynamic mathematical model based on anaerobic digestion model no. 1 (ADM1) was developed for accumulation (AC) system treating concentrated black water and faecal matter at different temperatures. The AC system was investigated for the treatment of waste(water) produced from the following systems: vacuum toilet for black water (VBW), vacuum toilet for faeces with urine separation (VF), dry ...

Optimizing Water Management in Hydraulic Fracturing for Shale Oil and Gas Production
Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

Clarke Energy on the Move with Lonsdale Power Station
Iberdrola Australia have appointed Clarke Energy as the main contractor to oversee and manage the relocation of a 120MW power station and associated plant from Lonsdale, in Adelaide’s south, to an industrial site in Bolivar (north of Adelaide) adjacent to SA Water’s wastewater treatment facility. The relocation of the power station to Bolivar will enable the gas turbines to be ...

Removal of cadmium ion from wastewater by carbon-based nanosorbents: a review
A green environment and a healthy life are dream projects of today's science and technology to save the world. Heavy metal ions in water affect both environment and human health. Cadmium has been identified as one of the heavy metals that causes acute or chronic toxic effects if ingested. Increasing use of cadmium in different technological fields has raised concern about its presence ...

Photocatalytic degradation of supra black–T dye on charcoal under sunlight
Azo dyes are used in many industries such as carpet manufacturing, textiles, paint, ink, plastics and cosmetics production processes. The coloured industrial effluent can pose serious problems in the aquatic environment. It is possible to get complete mineralisation of organic pollutants in water by photocatalysts. This study was carried out to examine the feasibility to remove supra black–T dye ...

Green hydrogen energy production and its critical importance on clean water
As the global economy starts to fully integrating other sources of energy in addition to fossil fuel, solar and wind, green hydrogen is starting to gain momentum. Global leaders across industry and governmental agencies are developing aspiring and potentially paradigm shifting ways to produce lower carbon energy fuels such as hydrogen. In the interim, other companies are evaluating how hydrogen ...

Water-saving analysis on an effective water reuse system in biodiesel feedstock production based on
Chlorella zofingiensis fed-batch cultivationThe micralgae-based biofuel obtained from dairy wastewater (DWW) is considered a promising source of energy. However, this process consumes water due to the concentration of wastewater being normally too high for some micoralgae cultivation, and dilution is always needed. In this work, the cultivation of microalgae has been examined in non-recirculated water (NR) and recirculated water systems ...
