Variations of disinfection by-product levels in small drinking water utilities according to climate change scenarios: a first assessment
In Québec, Canada, shifts in climate patterns (i.e., rainfall increase) could have consequences on source water quality due to the intensification of surface/groundwater runoff contamination events, leading to a decline in drinking water treatment efficiency and ultimately disinfection by-products (DBPs) formation following treatment. To assess the impacts of climate change (CC) scenarios on ...

Case Study: Arjo Wiggins Factory Site, North Hykeham
In January 2000, Blackwell were appointed as the main contractor for the remediation of an industrial site in Lincolnshire. The site was formerly used in the manufacture of thermal papers, had become contaminated with metalliferous mercy, zinc and asbestos. Site remediation was primarily driven by high ground water vulnerability. Following a comprehensive option study, volume reduction by Soils ...

Multifunctional Insulator Cleaning Agent RS-10
Multifunctional Insulator Cleaning Agent (RS-10) is mainly used for eradicating dirt, dust and contaminations on surface of the power equipment, especially clean that which surface was heavily polluted. After cleaning, RS-10 can significantly enhance the adhesion between the RTV coatings and the surface of insulator. The Advantages of Multifunctional Insulator Cleaning Agent RS-10:Remove the ...

Biofilter
Biofiltration is a pollution control technique using living material to capture and biologically degrade process pollutants. Common uses include processing waste water, capturing harmful chemicals or silt from surface runoff, and microbiotic oxidation of contaminants in air. Continue reading the full ...

The role of process water in pathogen reduction
The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...

What Is Dissolved Air Flotation?
In dissolved air flotation (DAF), fine bubbles attach themselves to suspended matter in a liquid, floating them to the surface for removal Dissolved air flotation (DAF) is a water treatment technology often used for the pretreatment of source water, but what exactly does it entail and how does it fit in with other technologies? DAF is a type of coagulation-flocculation technology typically ...

Electronic Water Treatment Reduces Fouling In Reverse Osmosis
Reverse Osmosis (RO) is used in processes requiring high-quality, purified water, such in semi-conductor processing or biochemical applications and can be used to treat boiler feed water, industrial wastewater or process water. A water purification technique, it reduces the quantity of dissolved solids in solution. RO uses waterline pressure together with energy consuming pressurizing pumps that ...

Introduction to Mining Wastewater Treatment: The Overall Guide
Mining waste comprises different types of rock, overburden, slurry and tailings from the processes of excavation and dressing. Further physical and chemical processing of a wide range of materials create additional waste from mining operations. Therefore, mine wastewater treatment is required, in order to avoid the contamination of the surrounding environment.This guide aims to explain ...

Titanium Scrap Metal Processing
Background A world-class processor of titanium scrap had a wash system whose cleaning solution was becoming contaminated with both free floating unemulsified tramp oil and emulsified water soluble oil that was being washed off of titanium turnings. As the level of oil contamination increased over time in the wash solution, cleaning effectiveness diminished. The processor uses a metric, which ...
