Our expert guide to treating industrial effluent, often referred to as trade effluent, examines the use and selection of speciality wastewater treatment chemicals including coagulants and flocculants and how they work. It reviews common treatment techniques including clarification, dissolved air flotation (DAF), filtration and biological treatments. It also considers techniques used for sludge dewatering and concludes with a guide to selecting the best treatment products for various wastewater streams.
Most industrial and manufacturing processes, whatever the industry sector, tend to use good quality or even purified water in one or more of their stages. Despite it being such a commonly used resource, there are a lot of misconceptions about how we reuse water which could have a major impact on how effective our processes are, both from a cost and environmental perspective. Read on to find out about the most common misconceptions surrounding the use and reuse of water in manufacturing processes, and what we can do about them.
Is testing water for lead a good idea? Well… whilst in the UK we are lucky enough to have a safe supply of drinking water people still worry about all sorts of contaminants getting into their water supply. One of those contaminants is lead, and it can cause very real health issues in humans if it’s not detected and dealt with properly.
This short article is about the treatment of wastewater. Wastewater treatment describes the process used to convert wastewater or sewage, water that has been used in some form of process and has become contaminated making it unsuitable for further use, or water that is no longer required into an effluent that can be either returned safely to the water cycle with minimal environmental issues or reused for either industrial or domestic consumption.
The following presentation considers issues around pollution prevention and control for UK business, looking at the potential effects pollution incidents can have on our environment including streams, rivers, watercourses and groundwater resources. It considers the consequences of a pollution incident and looks at practical ways UK businesses can help manage the risks of pollution to protect the environment. It looks at the importance of understanding on-site drainage systems, the management of waste streams, waste management, the disposal of trade effluent, preventing groundwater pollution and how to deal with a pollution incident.
Wastewater, or waste water as it is sometimes written, is water that has been used and undergone a reduction in quality from its original state. Wastewater can come from a variety of uses including commercial, industrial, domestic, farming and agricultural activities, storm-water or surface water runoff, and from sewer inflow or infiltration.
The term membrane technology is used to describe a variety of liquid filtration and separation processes that includes micro-filtration, ultra-filtration, nano-filtration and reverse osmosis. All these filtration processes have one thing in common – the use of a membrane as a major component in the separation process itself.
Typically speaking you will find a membrane used in technologies that filter water from various sources to get rid of any particulates (contaminants) in that water.
Desalination describes the water purification process that involves extracting salts and minerals from saline, salt water or seawater. It is a water treatment purification process that is used extensively around the World and its use is increasing as population growth, industrialisation and climate change impact the demands for clean water suitable for drinking purposes.
Salt water is commonly desalinated in order to produce purified water that is suitable for humans to drink (potable water) or use for the irrigation of crops.
When salt water is desalinated it produces fresh water with salt as a by-product.
