Water purification

Water purification is a process of removing undesirable chemicals, materials, and biological contaminants from raw water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (Drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacology, chemical and industrial applications. In general the methods used include physical processes such as filtration and sedimentation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain.

The standards for drinking water quality are typically set by governments or by international standards. These standards will typically set minimum and maximum concentrations of contaminants for the use that is to be made of the water.

It is not possible to tell whether water is of an appropriate quality by visual examination. Simple procedures such as boiling or the use of a household activated carbon filter are not sufficient for treating all the possible contaminants that may be present in water from an unknown source. Even natural spring water – considered safe for all practical purposes in the 1800s – must now be tested before determining what kind of treatment, if any, is needed. Chemical analysis, while expensive, is the only way to obtain the information necessary for deciding on the appropriate method of purification.

According to a 2007 World Health Organization report, 1.1 billion people lack access to an improved drinking water supply, 88% of the 4 billion annual cases of diarrheal disease are attributed to unsafe water and inadequate sanitation and hygiene, and 1.8 million people die from diarrheal diseases each year. The WHO estimates that 94% of these diarrheal cases are preventable through modifications to the environment, including access to safe water.Simple techniques for treating water at home, such as chlorination, filters, and solar disinfection, and storing it in safe containers could save a huge number of lives each year.Reducing deaths from waterborne diseases is a major public health goal in developing countries.

Peracetic acid

Peracetic acid (also known as peroxyacetic acid, or PAA), is a organic compound with the formula CH3CO3H. This organic peroxide is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive.
Peracetic acid is a much weaker acid than the parent acetic acid, with a pKa of 8.2.

Uses
Synthesis of other compounds
The main use of peracetic acid is for the industrial synthesis of epoxides. It transfers an oxygen atom to double bonds, e.g. in ethene and propene, to form epoxides and alcohols. It can also be used in producing synthetic glycerol from propene, and is used in nylon manufacturing.

Antimicrobial agent
Peracetic acid is an ideal antimicrobial agent due to its high oxidizing potential. It is broadly effective against microorganisms and is not deactivated by catalase and peroxidase, the enzymes that break down hydrogen peroxide. It also breaks down in food to safe and environmentally friendly residues (acetic acid and hydrogen peroxide), and therefore can be used in non-rinse applications. It can be used over a wide temperature range (0-40 °C), wide pH range (3.0-7.5), in clean-in-place (CIP) processes, in hard water conditions, and is not affected by protein residues.

Mechanism of action
Peracetic acid kills microorganisms by oxidation and subsequent disruption of their cell membrane, via the hydroxyl radical (HO·). As diffusion is slower than the half-life of the radical, it will react with any oxidizable compound in its vicinity. It can damage virtually all types of macromolecules associated with a microorganism: carbohydrates, nucleic acids (mutations), lipids (lipid peroxidation) and amino acids (e.g. conversion of Phe to m-Tyr and o-Tyr). This ultimately leads to cell lysis and true microbial death.

Application
The United States Environmental Protection Agency‎‎ first registered peracetic acid as an antimicrobial in 1985 for indoor use on hard surfaces. Use sites include agricultural premises, food establishments, medical facilities, and home bathrooms. Peracetic acid is also registered for use in dairy/cheese processing plants, on food processing equipment and in pasteurizers in breweries, wineries, and beverage plants.It is also applied for the disinfection of medical supplies, to prevent bio film formation in pulp industries, and as a water purifier and disinfectant. Peracetic acid can be used as a cooling tower water disinfect where it prevents bio film formation and effectively controls Legionella bacteria.

Bleaching agent
Peracetic acid can be used as a bleaching agent especially for Kraft pulp. It is used at weakly acidic pH and relatively low temperature. It is a relative efficient and selective bleaching agent, and it is often used as an alternative to chlorine dioxide and elemental chlorine in totally chlorine free bleaching sequences (TCF). It is however relatively expensive, and is difficult to store due to its high reactivity. This has limited its use.

Fowl sanitizer
Peracetic acid is extremely effective for sanitizing fowl carcasses without affecting the skin or the flesh of the bird carcass by applying direct to the meat. In particular, peracetic acid is applying to a fowl that has been killed, plucked and eviscerated by contacting the fowl with an aqueous peracetic acid solution and maintaining that contact to a time sufficient to sanitize the fowl.

About Disinfectant

Disinfectants are used to kill or inhibit the growth of microorganisms that are harmful to humans and animals. The microorganisms found on surfaces can be bacteria, viruses or fungi. Besides being used to control microorganism growth, disinfectants are used to protect surfaces against future growth. Antiseptics are disinfectants that are used on human tissues to destroy microorganisms, leaving the human tissues unharmed. The use of disinfectants has a long history, as humans have sought the perfect balance of safety and efficacy.

Disinfectants have been used to destroy or deactivate microbes that can cause infections, effectively reducing the risk of disease. They have been used to treat water, making it potable (drinkable), and have also been used in hospitals to control the spread of infection by microorganisms. They have also been used in the food industry to keep food free from contaminants that can spread sickness, and to destroy microorganisms that can form in human tissues.

Man has engaged in disinfecting practices since ancient times, but the science of using disinfectants to destroy microorganisms has only been around for 150 years. Heat was one of the first disinfectants, followed by the use of sulfur dioxide as a fumigant. In the medical field, as early as the 6th century, surgeons used special vapors to disinfect operating rooms. A few centuries later, ethanol was discovered, but was not used until the mid 1700s as disinfectant to dress wounds. In addition to ethanol, many other chemicals have been used, such as chlorine, vinegar water, hypochlorite, iodine, hydrogen peroxide and phenol. As the chemicals were being introduced, disinfection techniques and the reasons for disinfecting were becoming better understood.

There has to be a balance between the efficacy of the disinfectant and the overall safety of the product. It is generally understood that, the better a compound is at disinfecting, the more its toxicity increases--and vice-versa. Disinfectants have a negative effect on the environment; this should be taken into consideration when formulating new disinfectants.

Some microorganisms have started developing a resistance to disinfectants, making them ineffective. As new strains of microorganisms appear, new disinfectants are formulated to destroy them. This is similar to what is happening with antibiotics.
