According to recent data, published by EWG, 110 million Americans could possibly have Perfluoroalkyl and Polyfluoroalkyl substances (PFAS) contaminated drinking water sources. While these chemicals have been in use for many years, the extent of their environmental and human impact is only just beginning to surface. As of March 2020, the Environmental Working Group (EWG) ...
On April 11, 2005, APTwater (formerly known as Applied Process Technology, Inc). won their First International Order for 1,4-Dioxane Industrial AOP Wastewater Treatment, for a HiPOx advanced oxidation water treatment system that removed 1,4-Dioxane from industrial wastewater in South Korea. The HiPOx system will operate at a flow of 180 to 200 gallons per minute, reducing 1,4-Dioxane ...

Any nonylphenol compounds found in water have to be removed since they are endocrine disruptors. In this study, natural water from the river Ebro fortified with nonylphenol compounds (4n-nonylphenol and technical nonylphenol) is used as a sample in order to simulate a real situation in drinking water treatment plants. The aim is to compare conventional disinfection with advanced oxidation ...
Granular activated carbon (GAC) can be used to quench residual hydrogen peroxide (H2O2) after ultraviolet (UV)-H2O2 advanced oxidation processes in drinking water treatment. Bench- and pilot-scale studies examined the possible loss of GAC reactivity due to continuous exposure to natural water from a water treatment plant in both the presence and absence of H2O2. Six common types of GAC were ...
BioLargo, Inc. (OTC: BLGO) held its third annual “AOS technical symposium” last month, hosting a group of scientists, collaborators, water industry experts, and government representatives, according to a recent post on the company blog. Prior AOS symposiums have updated stakeholders on the company’s progress with their innovative technologies for high performance, low cost, ...
KEY WORDS Innovative Treatment, Advanced Oxidation, Reclaimed Water, Ultraviolet light, Peroxide, Disinfection, Microcontaminants INTRODUCTION Many regions of the United States, experiencing rapid population growth and faced with the challenge of meeting increased water demands, are turning to reclaimed water as an alternative water supply source. Concurrent with the rising need for reclaimed ...
Breaking the trend of agricultural appliances with the help of 14 V electricity; a system with high voltage was lately introduced in the farming sector. The government is providing power to engine auxiliaries and other electrically driven systems. It helps to reduce fuel consumption, under the load part conditions. Nowadays, more farmers are encouraged to use the high voltage system. ...

Highlights include an innovative ...
In water and wastewater treatment, chemistry is king. Treatment options are evaluated depending on the quality of water to be treated and the treatment application. Treatment systems including AOP systems, are designed to specifically target certain constituents and remove or reduce them from the water. This takes places through the power of chemical reactions. Even biological treatments involve ...
In recent years, improvement in ozone based advanced oxidation process design and efficiency resulted in lower capital and operating costs. An investigation into alternatives for hard COD, TOC and foaming agent oxidative destruction which is economically attractive and do not generate sludge, lead to the evaluation of our ozone based advanced oxidation processes (AOP). The results of this pilot ...
This work is focused on the study of the suitability of the photo-Fenton process as a pretreatment for water highly contaminated with a methomyl commercial formulation in Advanced Greenhouses devices. Initial concentrations of reagents and pesticide were evaluated according to a central composite experimental design, with methomyl depletion and biocompatibility of the final effluent as response ...
Scientists at the University of Alberta, Department of Agricultural, Food and Nutritional Science validated the unprecedented effectiveness of BioLargo’s (BLGO) AOS Filter in removing contaminants from water. The tests demonstrated a level of efficiency that has never been seen before in destroying highly concentrated contaminants in sample water, including Listeria and Salmonella. ...
Benefits & Disadvantages of the Advanced Oxidation Process In many water and wastewater treatment applications, there are a number of pollutants that are difficult to reduce by physical, chemical, or biological means alone. In more recent years, there has been a growing concern regarding pharmaceutical drugs in drinking water and aquatic environments. Pesticides get caught in runoff from ...
In many water and wastewater treatment applications, there are a number of pollutants that are difficult to reduce by physical, chemical, or biological means alone. In more recent years, there has been a growing concern regarding pharmaceutical drugs in drinking water and aquatic environments. Pesticides get caught in runoff from farms into freshwater supplies. Personal care products are ...
Nanotechnology holds great potential in advanced water and wastewater treatment to improve treatment efficiency.
