How do you remove pathogenic bacteria from a wastewater treatment plant?
Pathogenic bacteria can be removed from a wastewater treatment plant through physical processes such as filtration, chemical disinfection using chlorine or ultraviolet light, and biological treatment utilizing beneficial bacteria to outcompete the pathogenic ones. Adequate monitoring and maintenance of the treatment processes are essential to ensure effective removal of pathogenic bacteria.
Does wiping a doorknob with an antibacterial wipe really reduce the numbers of bacteria?
Yes, wiping a doorknob with an antibacterial wipe can help reduce the number of bacteria present on the surface. However, it may not completely eliminate all bacteria. Regular cleaning and disinfection can help lower the risk of germ transmission.
What is the ratio of good to bad bacteria on any given object?
The ratio of good to bad bacteria on any given object can vary greatly depending on factors such as the type of object, its cleanliness, and its environment. In general, however, it is common for surfaces to have a mix of both good and bad bacteria, with some objects harboring more harmful bacteria than others. Regular cleaning and good hygiene practices can help maintain a healthy balance of bacteria.
What are the advantages and disadvantages of using paper towels compared to cloth towels for cleaning and drying purposes?
Paper towels are convenient and disposable, making them hygienic for cleaning and drying. However, they are not environmentally friendly as they contribute to waste. Cloth towels are reusable and eco-friendly, but they require washing and may harbor bacteria if not cleaned properly.
How often should a household toilet be cleaned?
For maximum cleaniness, once a week is recommmended. However, one cleaning per month would be sufficient to keep it clean of germs. That would also depend on the types of accessories that you are using.
Wastewater is treated with chlorine to kill bacteria. However, chlorine can be toxic to certain fish that live in the ocean. Why does this most likely add to the cost of cleaning water?
C.Water must have the chlorine removed before it is dumped back into the ocean.

Where Chlorine used For Killing Bacteria?
Chlorine is commonly used for killing bacteria in swimming pools, water treatment plants, and household cleaning products. It is effective at disinfecting surfaces and killing harmful microorganisms due to its strong oxidizing properties.
Do baby carrots have chlorine in them?
Yes, baby carrots may be washed in a chlorine solution to kill bacteria. However, the chlorine levels are regulated to ensure they are safe for consumption.
Does alcohol react with chlorine?
Alcohol does not react with chlorine under normal conditions. However, mixing alcohol with chlorine bleach can produce toxic fumes that are harmful to health. It is important to avoid mixing alcohol with cleaning products containing chlorine.
Which allows more bacteria salt water or chlorine?
Chlorine typically is more effective at reducing bacteria compared to salt water. Chlorine is a strong disinfectant commonly used in swimming pools and water treatment plants to kill bacteria, viruses, and other contaminants. Salt water pools rely on a chlorine generator to produce chlorine from salt, so the effectiveness can vary depending on the salt levels and maintenance.
Is chlorine man made?
Chlorine is a chemical element that is not made by humans but is found naturally in the Earth's crust and in seawater. However, most of the chlorine used in industry is produced from brine or by electrolysis of salt water.
Is bleach the same as chlorine?
No, bleach is a chemical cleaning product that often contains sodium hypochlorite as the active ingredient, whereas chlorine is a chemical element. However, sodium hypochlorite is a compound derived from chlorine, so bleach does contain chlorine but they are not exactly the same.
Is chloride used in public water to kill bacteria?
Chloride itself is not used to kill bacteria in public water supplies. However, chlorine compounds, such as chlorine gas or chlorine dioxide, are commonly added to water treatment systems to disinfect and kill bacteria. These compounds can react in water to form chloride ions, which are not harmful in the concentrations typically found in treated drinking water.
Does chlorine evaporate?
Yes, chlorine can evaporate at room temperature. As a gas, it is released from surfaces where it has been applied, such as in swimming pools or cleaning products. However, it is important to handle chlorine safely as inhaling high concentrations can be harmful.
Can sperm live in chlorine?
They cannot survive in a 100% pure chlorine solution. However, for a very brief period they may survive in an extremely dilute chlorine solution.
Does chlorine remove the odour?
Chlorine can help reduce odors in water by eliminating bacteria and other contaminants that cause them. However, chlorine itself can also produce a distinct odor that some people find unpleasant. To eliminate this chlorine odor, you can use activated carbon filters or allow chlorine to dissipate by leaving water uncovered for several hours.
