Casiraghi, what are the parameters contained in the water and what value should they correspond to? This is one of the aspects that makes people more aware that due to the change in hardness, the taste of water is affected. Waters with low hardness, called sweet, are lighter and, for example, oligomineral or mountain waters. While more limestone waters are called hard and naturally a little heavier.

These are two factors related to the nitrogen cycle and very often field fertilizers, and in some cases they can have negative health effects. These are not direct indicators of the presence of bacteria, but may be affected by their presence. Contaminated waters, made of bacteria and therefore microbiologically incorrect, in principle have variations in these two parameters.

If the water is very heavy, that is with very lime, what happens? There was once a great fear that hard water would have consequences, today Scientific research tassal was imposed on him. Harder waters do not cause this problem. Speaking of characteristics, we can say that harder water usually rinses off better, for example, when you go to the mountains and rinse your hands, you always try to remove the soap, because light water, such as mountain cleaner, the hardest water usually causes problems with objects that can easily damage household appliances, home pipes and faucets.

Drinking more solid water means absorbing a substance rich in salt, and the more powerful it is. The ideal would be to alternate waters with different degrees of hardness: in summer some water rich in mineral salts, so as not to take additives, and in winter - less water. Are there ways to soften water, for example?

What you have to say is that the stiffness parameter has no real law obligation, there are more than other recommended values. However, there are many softening solutions on the market - these are tools called softeners, which, for example, using activated carbon filters, make water lighter.

We are often accustomed to consuming oligomineral waters and therefore very light, slightly heavier water may not really please, not a real health problem, but simply a matter of heaviness. It is important, however, to pay attention to the use of softeners, because, for example, if you use poorly packaged softeners or do not follow cartridge replacement times, you may become too tired of the water and even drink almost distilled water, given hardness values ​​that are too low, not advisable.

Many times the water knows about chlorine. Is chlorine bad or is it just a matter of taste? This is one of the aspects that worries more people, especially regarding tap water. We began to identify systems to control the hardness of our aquarium, considering simply mixing demineralized water with tap water. This is without a doubt the simplest system.

Exist different types, more or less complex and more or less expensive. They basically consist of a tube containing a special membrane equipped with micropores. Water passes through the pores. Thus, all the salts contained in the water are stored on one side of the membrane and are “washed away” from the wastewater. The resulting liquid may be more or less close to the chemical characteristics of distilled water, depending on the type of membrane and accessories that complicate the implant. Very thin microporous membranes, which often require pumps to seal the implant, give an overall hardness close to zero.

Water quality can be further improved by the presence of prefilters upstream of the osmosis unit and resins downstream. Such a plant has a very low cost, but makes us independent in producing clean water for our aquarium. Costs are reduced with simple plants that produce water with minimal overall hardness, often using slightly larger porous membranes.

Since we rarely want to use fully demineralized water, simply use formula 2 to calculate how many gallons of water to add to get correct values for breeding our favorite species. It looks complicated, but it's not!

The tank volume is 60 liters. What if we mix these two waters in proportions of 40 liters and 20 liters? This way we have complete control over our water: just apply the formula. The third system we will look at to correct hardness is ion exchange resins. These substances, placed in a filter or anyway along a waterway, exchange ions to reduce the amount of solutes.

There is an ion exchange resin for every need! Water hardness is an index that we must know when using these household appliances. This index highlights the amount of calcium and magnesium salts contained in water: water rich in such salts is defined as hard water. These "hard" waters cause problems such as dispersion in distribution pipes, internal installations and user equipment. Let's find out how to do a proper wash.

Let's see how water hardness also affects washing with a washer. washing machine and dishwasher. Detergents contain surfactants which act as a detergent and their effectiveness is determined by the presence of calcium and magnesium ions, if the presence of these ions is high and therefore the water is hard, more detergent will need to be used to get your laundry clean. Bottles of these detergents are dosed according to the hardness of the water.

What to do to know this data?

You can ask your community for information, otherwise you can measure your water hardness at home using kits you buy at hydraulic stores. The energy efficiency of appliances also depends on quality. Using it in at its best and waste reduction water resources very important in relation to various aspects, primarily environmental, but also economic and social.

Filter the water through the installation of a self-cleaning mechanical filter that eliminates contaminants coming from the aqueduct. Keep the filter clean. If the pressure is high, install a pressure reducer on the inlet hose, thanks to this small tool, and also save up to 20% of water, you can protect the proper functioning of your home appliances, avoiding the "knocking" phenomenon.

Exceeding this threshold is not only dangerous, but also significantly increases the cost of water production and management. In general, very hard waters contain so much limestone that, while not harmful to health, they cause appliances to become less efficient, leave stains on the surface, and cause them to use more detergent.

Install a disconnector into the system. This is a tool that, in the event of reflux from plant pipes, protects drinking water networks by discharging potentially contaminating liquid. In fact, there are phenomena associated with back pressure, so water can flow in the opposite direction to where it should. There is European legislation in this direction, but it is often forgotten by employment specialists.

Install a fall protection system for flood protection: This solution uses sensors distributed throughout the home and can shut off the flow of water when an abnormal leak is detected. There are many websites that allow you to analyze your “virtual water consumption” and help you calculate how much water you are using. Even more expensive, buying high-quality Class A appliances is a great investment for the future. Additionally, it is always advisable to have proper maintenance of the systems by checking the pipes regularly.

A faucet that loses one drop before the second dissipates about 000 liters in a year. Periodically turn off all taps to check if the water meter is working, if so, there is a leak. Volatization of water. This is a fundamental intervention for a number of reasons, primarily because it is responsible for the end user, who will pay the bill based on actual consumption. This tends to reduce maintenance costs and is a fairness factor.

Already in ancient times, it was noted that some waters have the property of melting soap and are not suitable for cooking legumes. The term was then used to classify waters based on their calcium and magnesium content. Of course, the two units of measurement are in a direct ratio.

Several classifications of water based on their hardness have been proposed, but to date there is no generally accepted one. Water hardness, in addition to the effects described above, leads to the formation of deposits in distribution pipes, room installations and user equipment. Above certain values, the organoleptic characteristics of water are also affected; But there are no documented human health consequences from water that is too hard.

The importance of water hardness when flushing

The presence of hardness ions in the water used has a decisive influence on the washing results. In fact, the detergent effect of any surfactant, the main ingredient of detergents, is greatly reduced due to the presence of calcium and magnesium ions as its solubility and hence its effectiveness is greatly reduced. A good wash of any type, fabric or surface can only be obtained if the amount of calcium and magnesium ions in the solution is reduced to very low levels.

To achieve this, detergents contain ingredients that can block the negative effects of water hardness components. These ingredients are, for example, zeolite, sodium carbonate and the same soaps. The higher the hardness of the water, the greater the amount of these ingredients that must be dosed to achieve a clean wash and hygienic washing results; Therefore, water with low hardness requires lower doses of detergent. Labeling instructions on containers provide consumers with the correct doses to use based on water hardness.
