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.
Reverse osmosis, often abbreviated to RO is a purification procedure that uses membrane technologies to filter and purify liquids. Reverse osmosis is now commonly used around the world for the treatment and purification of water used for drinking (potable water) and industrial processes.
Reverse osmosis makes use of a semipermeable membrane to separate unwanted materials found in the raw water (solute). These materials can include salts and minerals, bacteria and other contaminants.
Industrial wastewater describes water that originates from an industrial or commercial process and that may have been contaminated in some way so as to reduce overall water quality… industrial wastewater treatment should therefore form an important part of an organisations waste management processes.
Industrial contamination of this nature may have reduced the quality of the water making it unsuitable for reuse or discharge to drain without appropriate treatment.
Rainwater harvesting is an environmentally friendly process that focuses on capturing, harvesting and then recycling as much rainwater as possible for re-use that would otherwise be lost down drains when it rains.
The most obvious example of rainwater harvesting is when one fits a diverter to a surface water drainpipe so that the rainwater run-off is collected in a water butt or other water storage tank, rather than simply being allowed to discharge to the drain.
