$A solution to fracturing water supply and disposal issues$

A solution to fracturing water supply and disposal issues

“Water, water, everywhere, Nor any drop to drink.” –The Rime of the Ancient Mariner, Samuel Taylor Coleridge Many topics of conversation among oil and gas industry professionals are predictable – oil price trends, the “great shift change” imperiling the available workforce, and production quotas and caps from OPEC. Yet one pressing topic among those developing ...

How industrial water filtration can improve efficiency and save you money

Over the course of the past couple of decades, industrial water filtration has become one of the most important considerations for the average manufacturing facility in North America. These concerns have only increased as water supplies have dwindled and wastewater contamination standards have become more stringent. All of this has led to the need to choose the right industrial water filters and ...

Arsenic Removal

The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...

Removal of cyanide from liquid wastes by modified clinoptilolite

This paper describes the preparation and evaluation of various cationic forms of clinoptilolite for removal of cyanide from aqueous solutions. The cobalt form of the zeolite showed the highest uptake of 1.95 meq of cyanide per gram of zeolite, whereas the uptake of natural forms is 0.070 meq g-1. The kinetics of cyanide desorption into solutions with different ionic strength were studied. ...

Dynamic restructuring of waste removal in decentral plants

The mechanical and biological treatment of residual waste meets the requirements for the production of defined material flows out of nonspecific waste. The specific material flows can reach the quality demands of the industry by wet screening, when beforehand the result of composting is a far-reaching biological stabilisation of the residual waste. Three fractions can be separated: recyclable and ...

Removal of hexavalent chromium from aqueous solution by lignocellulosic solid wastes

The batch removal of Cr(VI) from aqueous solution using lignocellulosic solid wastes such as sawdust and pine leaves under different experimental conditions was investigated in this study. The influence of pH, temperature, contact time, initial concentration of Cr(VI) and particle size on the chromium removal was investigated. Adsorption of Cr(VI) is highly pH-dependent and the results indicate ...

Removal of viruses and indicators by anaerobic membrane bioreactor treating animal waste

Appropriate treatment of agricultural waste is necessary for the protection of public health in rural areas because land-applied animal manure may transmit zoonotic disease. In this study, we evaluated the potential of using a pilot anaerobic membrane bioreactor (AnMBR) to treat agricultural waste. The AnMBR system, following a conventional complete mix anaerobic digester (CMAD), achieved high ...

Using ‘TransMembraneChemiSorption’ (TMCS) for Ammonia Removal from Industrial Waste Waters

Dissolved gases like NH3, H2S or NOx in waste water lead to contamination in the sewage system and high treatment costs for municipal waste water treatment plants. This translates into high penalty fees that are paid by the company discharging these contaminates into the sewage stream. In many cases a membranebased water treatment system can be justified because of a favorable pay back time. ...

Go for the Cheap but Secure Lab Waste Removal and Recycling Plan!

In the last couple of decades, the number of laboratories that are part of universities, hospitals and other facilities is growing and this is definitely good news. Thanks to these labs we can improve our quality of life. However, during the process of research and use of these labs, specialists who work there create lab waste. This waste can be potentially dangerous and this is the reason why ...

CERCLA remedial and removal actions at historic waste disposal areas.

Apache Nitrogen Products, Inc. (ANP) has operated a nitrogen-based fertilizer and explosives manufacturing facility in rural Cochise County since 1921. Using a feedstock of anhydrous ammonia, current manufacturing processes produce nitric acid, solid and liquid ammonium nitrate, and various ammonium nitrate-based fertilizer products for regional mining and agricultural markets. Historically, ...

Removal of arsenic from an aqueous solution by pretreated waste tea fungal biomass

Arsenic exists in natural waters both in inorganic and organic forms. The inorganic form of arsenic is more toxic compared to its organic form. Inorganic arsenic is the predominant form in contaminated groundwater. Arsenic exists in two,oxidation states: arsenite, As (III) and arsenate, As (V) (Pokhrel and Viraraghavan, 2006). It is introduced in the aqueous system through geochemical reactions ...

Further contributions to nitrogen removal modelling in waste stabilization ponds

A large database from an experimental maturation pond system in Brazil was used to verify the agreement of field results with values predicted by some of the most widely accepted models to describe ammonium and total nitrogen (TN) removal in facultative and maturation ponds. The same database was used to derive a pH-independent linear model to predict ammonium removal in ponds, which was proved ...

Waste agricultural fibres highly effective removing water pollution in developing countries

Discharging different kinds of wastewater and polluted waters such as domestic, industrial and agricultural wastewaters into environment, especially to surface water, can cause heavy pollution of this body sources. With regard to increasing effluent discharge standards to the environment, high considerations should be made when selecting proper treatment processes. Any of chemical, biological and ...

Application of silica gel factory waste for methyl orange dye removal

The silica gel waste (SGW), after its collection from a local factory (at Kolkata, India), was modified with cationic surfactant and was utilised as an adsorbing media for the removal of methyl orange dye from aquatic environment. In batch mode, the effect of different dissolved salts, solution pH, and surfactant surface coverage on SGW were studied. Presence of electrolyte and solution pH was ...

Biological nitrate removal using waste-derived extracts as sole carbon source

Waste-derived multicomponent extracts were investigated as carbon source for biological nitrate removal. Aerobic and anaerobic sludge from a municipal wastewater treatment plant and leachate from an anaerobic digester treating food waste were studied. Alkaline-heat treatment was used for sludge solubilisation. More than 90% carbon was recovered at pH 10–11. The extracts contain very high ...
