Freeword – everything you anxiety need to know about water treatment – the energy bit

Water is arguably one of the most important natural resources beck’s anxiety inventory test pdf on the planet and a necessity for life. Finding and maintaining a clean water supply has been a beck’s anxiety inventory test pdf constant process throughout human history, and the earliest records of treating water have been found beck’s anxiety inventory test pdf in ancient greek and sanskrit writings from 2000 BC. The importance of water treatment

As a consequence of the increasing population, the demand for drinkable water has been on a constant beck’s anxiety inventory test pdf rise. This has led to serious concerns as the high quality beck’s anxiety inventory test pdf of water supply has been very limited due to the beck’s anxiety inventory test pdf contamination of water with municipal, agricultural, and industrial waste that has led to decreasing water quality.


Therefore, the public has become more aware of the importance of beck’s anxiety inventory test pdf water quality control and its effects on our ecosystem. Water quality standards & legislation

Water-quality standards are presented to help in the selection of beck’s anxiety inventory test pdf suitable water-treatment technologies. The relevant issues such as topical and spatial variations, problems of supply and distribution of safe and pure water, and possible approaches to water management have to be taken beck’s anxiety inventory test pdf into consideration. Especially water-scarce areas should ensure high-quality water treatment processes so the treated water can be beck’s anxiety inventory test pdf reused or recycled, and never wasted.

We are witnessing declining freshwater supplies around the world. Wastewater, which is basically used water, is believed to be the solution to resolve this global beck’s anxiety inventory test pdf crisis. Adequately treated wastewater is a source for many purposes such beck’s anxiety inventory test pdf as irrigation, landscaping, industry, etc. And is a convenient way to conserve our freshwater resources. A proper wastewater treatment allows the maximum amount of water beck’s anxiety inventory test pdf to be reused instead of going to waste. Untreated, the chemical compounds and pathogens in wastewater are destructive for beck’s anxiety inventory test pdf the whole ecosystem. In addition, the treated water is usually added to groundwater or surface beck’s anxiety inventory test pdf water for further cleansing before being sent to a potable beck’s anxiety inventory test pdf water supply where it is re-treated. Water treatment processes

There are two main types of water treatment plants: potable water plant and wastewater plant. Both serve the purpose of removing contaminants from the water, but in general, the output of wastewater plants are streams or rivers, and the output of potable water plants is your city’s pipe network distribution system. So, how exactly does a treatment plant take dirty river water beck’s anxiety inventory test pdf and turn it into clean water? Well, through processes involving chemicals and filters, water can be removed off most toxins and hazards and beck’s anxiety inventory test pdf become potable again.

Tertiary treatment – the wastewater is raised through disinfection practices mostly as chlorination beck’s anxiety inventory test pdf or the use of ultraviolet light. There are other methods like sand filtration, but they are rarely used. Chlorine is inexpensive and effective but can create carcinogenic compounds. Ultraviolet light results in water that’s healthier for the environment, since it’s deadly to bacteria and viruses by changing their genetic beck’s anxiety inventory test pdf structure, which makes them incapable of reproducing. Moreover, a combination of tertiary treatments can be used.

Aerobic digestion – it is a natural oxidation process that causes an efficient beck’s anxiety inventory test pdf breakdown of organic pollutants and yields. Aerobic wastewater treatment is a rapid and efficient process that beck’s anxiety inventory test pdf removes at least 98 percent of organic contaminants. On the negative side, aerobic digestion consumes large amounts of energy, resulting in large amounts of bio-solids, or sludge, which require disposal.

Anaerobic digestion – anaerobic microbes are bacteria and microorganisms that function in the beck’s anxiety inventory test pdf absence of oxygen. Anaerobic wastewater treatment is more environmentally friendly than aerobic digestion, because it produces less biomass, requires less energy, and produces methane that can be recycled. On the negatives, it’s slow and less efficient than aerobic digestion (70 to 95% of contaminants can be removed).
