Boiling is the oldest method of household water treatment, and today it's practiced by an estimated 600 million people around the world Boiling of Water Heat, in fact, kills through different mechanisms heat impacts enzymes and causes them to denature and become non functional. It can affect the proteins that make up cells and cause them to unfold and change their shape. And also within a cell it can increase the pressure which damages cells.  We'll look at two broad classes of heat treatment; boiling and pasteurization. To understand how heat disinfection works we have to first think a little bit about temperature and pressure, and recognize that pressure affects the boiling point. If the pressure is higher, then the boiling point can be higher. And in fact, this is how an autoclave works with steam sterilization and high pressure about one bar above atmospheric pressure and that allows water to reach 121 degrees Celsius. And if it's kept there for 15 minutes under steam i...

The first assessment from the Intergovernmental Panel for Climate Change in eight years will sound the alarm on soaring temperatures and other effects of unchecked carbon pollution A woman gets a hand from a friend as they walk in flooded streets as the Neuse River begins to flood its banks during Hurricane Florence September 13, 2018 in New Bern, North Carolina. Credit: Chip Somodevilla Getty Images The United Nations is poised to release the most confident and comprehensive assessment yet of global warming, including detailed estimates of how continued greenhouse-gas emissions will increase Earth’s sea levels and drive extreme weather in the coming years. Compiled by more than 200 scientists and approved by government representatives from 195 countries, the report from the Intergovernmental Panel on Climate Change (IPCC) will leave little doubt that humans are altering the way the planet functions — and that things will get much worse if governments do not take drastic action, say cl...

Filters in household faucets and genetic technology could help reduce this public health threat, biologist Rebecca Fry says Credit:  Michael Hall  Getty Images Arsenic’s potent effect on humans has been known since at least the Roman Empire. For centuries, it was a popular poison for murderers because it can’t be seen, smelled or tasted in food or water. That made it difficult to detect. As chemical detection methods improved, its use as a poison declined. But arsenic, a naturally occurring chemical element in the Earth’s crust, remains a threat to human health. Regular, long-term exposure increases the risk of chronic disorders such as cancer, diabetes and heart disease for millions of people around the world.

A new generation of tech uses heat from the sun to provide clean, salt-free water Solar-thermal technologies could process seawater and groundwater to make it drinkable at less cost. Credit: Warren Keelan In an increasingly hot and crowded world, clean water is becoming a precious commodity. Two thirds of the global population will have problems accessing fresh water by 2025, and removing salt and contaminants from the oceans and groundwater is one way to slake humanity's thirst. Today's large desalination plants, though, cost millions of dollars to build. Most use reverse osmosis, which forces seawater through salt-blocking membranes. The required electricity accounts for up to  half of a plant's expenses , and the process leaves behind a supersalty, chemical-laced soup that can  harm local ecosystems . Such facilities are typically powered by carbon-emitting fossil fuels; efforts have been made (especially in the Middle East, Asia and Africa) to use solar panels instead, ...

Experts hope that with the incoming Biden administration, the federal government will finally regulate a class of chemicals known as PFASs Credit:  Thomas Trutschel   Getty Images Many Americans fill up a glass of water from their faucet without worrying whether it might be dangerous. But the crisis of lead-tainted water in Flint, Mich., showed that safe, potable tap water is not a given in this country. Now a study from the Environmental Working Group (EWG), a nonprofit advocacy organization, reveals a widespread problem: the drinking water of a majority of Americans likely  contains “forever chemicals.”  These compounds may take hundreds, or even thousands, of years to break down in the environment. They can also persist in the human body, potentially causing health problems. A handful of states have set about trying to address these contaminants, which are scientifically known as perfluoroalkyl and polyfluoroalkyl substances (PFASs). But no federal limits have bee...

Automatic Dosing Device Under this topic we shall consider chlorine disinfection, which is the most widely used disinfectant globally.  We'll explore a bit the chemistry of chlorine and chlorine dosing.  We'll look at different forms of chlorine; gas, liquid, and solid.  And review the effectiveness of chlorine in reducing pathogens.  Chlorine has been used for over a century for the treatment of drinking water.  Beginning in the UK and USA in the early 20th century.  Today, chlorine is used in 98% of U.S. water utilities and in similarly high numbers  across the world. Chlorine is also widely used at the household level.  Of course, many households use bleach for cleaning and laundry.  But in surveys conducted in low and medium income countries, 5.6% of respondents  reported  adding chlorine to their drinking water to make it safer to drink.  This was the second most common household water treatment practice men...

Ultra Violet Lamp We'll look at both artificial and natural radiations, which needs electricity and lamps to generate the energy, and natural radiation, making use of the sun's energy for solar disinfection. Ultraviolet radiation is one type of energy along the electromagnetic spectrum, where different kinds of radiation are defined by their wavelength. Ultraviolet has wavelengths in the 100 to 400 nano meter range, whereas the visible light is in the 400 to 700 nano meter range. If we zoom in on this range we can define some subcategories. 1.The lowest wavelength we call vacuum UV. It only exists in the vacuum, but then we have UV-C, or deep ultraviolet, where the germicidal peak at 260 nano meters is found. Then you've got UV-B and UV-A shading into the visible light spectrum from 400-700 nano meters. Now in order to describe the efficacy of UV light against different types of pathogens, weneeds to first define the dose. And just as for heat, it's importan...
