A study of the reaction of ferrate with pentachlorophenol – kinetics and degradation products
Pentachlorophenol (PCP) is a persistent pollutant which has been widely used as a pesticide and a wood preservative. As PCP is toxic and is present in significant quantities in the environment, there is considerable interest in elimination of PCP from waters. One of the promising methods is the application of ferrate. Ferrate is an oxidant and coagulant. It can be applied as a multi-purpose ...

Introduction of chlorine scrubber (purification tower)
Chemical principle: Using ferrous chloride solution as the absorption liquid and iron as the regenerant, chlorine and ferrous chloride undergo a redox reaction to generate ferric chloride, which can be reduced by the regenerant. The chemical reaction formula is as follows: 2FeCL2+2CL2=2FeCL3 2FeCL3+Fe=3FeCL2 Advantage: 1. Strong absorption capacity and large capacity, the ferric chloride ...

Emergency equipment for the absorption of chlorine in hospitals - Case Study
Chlorine is a strong oxidant that in normal conditions and in its pure state formsdichlorine, a toxic gas with a yellow-greenish colour formed by diatomic molecules (Cl2) that are about 2.5 times heavier than air and have an unpleasant smell. Among its multiple applications and due to its powerful oxidising nature, it is widely used forwater purificationin sewage treatment plants and as a ...

Groundwater Plume, Source and Risk Identification Using Passive Soil Gas
Abstract The results from sixty passive soil gas (PSG) samplers placed at a grain silo and mixed-use industrial facility with a known chlorinated solvent release aided with the rapid investigation time-schedule. The samplers were used to determine potential sources, plume extent and vapor risks in areas beyond the previous discrete soil sampling and permanent groundwater monitoring well network. ...

Project - Emergency Equipment for Chlorine Adsorption in Hospitals
Chlorine is a strong oxidant that under normal conditions and in its pure state forms dichlorine, a yellow-greenish toxic gas formed by diatomic molecules (Cl2) about 2.5 times heavier than air, with an unpleasant and toxic odor. Among its many applications and due to its strong oxidizing character, it stands out especially for being a compound widely used in water purification in WWTPs ...

Shining a new light on de-chlorination - Case Study
In collaboration with a UK Utility company, atg UV constructed an independently reviewed de-chlorination test rig and trial at its Lancashire headquarters in January of this year. Barry Hopton of atg UV Technology discusses with WWT how portable UV systems can provide a more efficient and proven alternative to de-chlorination of drinking water. The Water Industry is Changing its ...

How to reverse the causes of ozone layer destruction
Since the causes of ozone layer depletion were identified, solutions were put into place to reduce or eliminate their usage. The U.S. Clean Air Act and the Montreal Protocols address the problem internationally. The goal of these treaties is to stop the damage to the ozone layer by phasing out known contributors.Although there are numerous causes of ozone layer depletion, chloroflurocarbons have ...

How Much Disinfectant is Safe?
Like most things, too much of a good thing can be harmful. Over-concentration of disinfectant can have adverse health effects for you, your family, employees, and customers. My daughter has asthma, and she spent a lot of time in her young life at the hospital. Her symptoms continuously increased when the school year started, drastically affecting her. I believe it was a combination of things: ...

Evaluation of Ecological Risks Associated with the use of Chlorine Dioxide for the Bleaching of Pulp: Scientific Progress Since 1993
1.1 Scope and Objectives A small number of viable options are presently available for the bleaching of wood pulp (delignification and brightening) during the manufacture of pulp and paper. The use of chlorine dioxide (ClO2) in the bleaching process has largely superceded the earlier use of Cl2, or elemental chlorine, in the majority of North American pulp mills: It was discovered over a decade ...

Bioaugmentation to Treat Chlorinated Solvents in Fractured Bedrock
ABSTRACT: An in situ bioremediation pilot study was performed at a former industrial site in New Jersey where groundwater has been impacted by historical releases of chlorinated solvents. The target area for treatment is a fractured, intermediate bedrock zone. The remedial objective at the Site is to treat the groundwater while minimizing the impact of the remedial system on the re-development of ...

Toxins Found in E-Waste
One of the worst effects of a skyrocketing, global e-waste crisis is the risk of toxic contamination for the environment and communities. In fact, delving into the many chemical and heavy metal materials that make up most electronic devices, it seems that toxins and electronics go hand in hand. Though many manufacturers of electronic devices are finding innovative ways to work around toxins found ...

Volatility of heavy metals during incineration of tannery sludge in the presence of chlorides and phosphoric acid
Knowledge of the behaviour of heavy metals in the combustion process is a most important factor in selecting disposal alternatives for waste materials. Accordingly, in this work, the vaporization behaviour of highly concentrated heavy metals (Pb, Zn, Cu and Cr) in tannery sludge were investigated experimentally. The sludge was spiked with various chlorine compounds (i.e. PVC, FeCl3, CaCl2 and ...

Case study - Ozone sparging closure of an industrial VOC spill site adjacent to a water supply well site
Description An undocumented surface spill at an active manufacturing facility located adjacent to a public water supply well field released chlorinated volatile organic compounds (PCE, and its breakdown products: TCE, c-DCE, and VC) into soils and groundwater. The driver for site cleanup was three water supply wells located 200 feet downgradient of the site bounds. The chosen endpoint ...

The Hidden Dangers of Industrial Mop Water, Examining little-known threats to the environment & wastewater treatment processes
When we think of mop water, most likely we think of our kitchen floor. In industrial plants, however, mop water could contain a toxic blend of chemicals that are mopped off the floor, and sometimes end up in our rivers, streams and municipal wastewater systems. While we consider the health of our environment, we don’t necessarily realize the hidden dangers of mop water. This article ...
