For a few years more as well as more people are turning towards those alternative systems in which allow the home water purification. A realization motivated by several factors: incomplete information of the substances contained inside the water inside the bottle as we have seen, economic savings, safeguarding the environment as well as convenience. Just look at the queues at the supermarket; with tons of bottles to carry back home which will be recycled with considerable costs.
These devices are connected directly to the tap at home or to the main pipeline as well as are able to filter water, creating the idea not only more Great yet also safer for health. The cost of household cleaners will pay for itself in a few months, requiring only maintenance.
Of all domestic water purification systems, only those with reverse osmosis, work fine as well as can actually eliminate more than 99% of the harmful substances found in tap water, thus creating the very best water as well as sure of, many bottled brands. These plants, in fact, are used for several years by hospitals, by humanitarian organizations such as UNICEF, the chemical laboratories as well as major companies producing beverages through around the earth (ie. Cold Drinks, beer, etc.) to produce as well as consume pure water in very large quantities.
The same type of equipment fitted with reverse osmosis, can be used by many humanitarian as well as government entities associations occurring after natural disasters (earthquakes, floods, etc.) to produce perfectly clean water through polluted sources. In addition, some of the bottled water sold every day in supermarkets can be nothing more than spring water filtered by reverse osmosis purification systems!
The “Great” water should be free or very low in harmful substances such as: chlorine, nitrites, fluorides, chlorides, lead, phosphates, ammonia, bromide, etc. In fact the tap water as well as bottled water may contain these harmful elements, often with values close to the limits imposed by law. The presence of these harmful elements can depends on pollution of groundwater caused by pesticides used in agriculture, through detergents used daily inside the home, through lubricating oils disposed of outlaws (eg. thrown inside the gutters), as well as the increasingly frequent illegal dumps in which pollute subsoil. With the Reverse Osmosis however, you can eliminate the most dangerous as well as harmful chemical elements up to 99%, bringing also the worst tap water in Italy in levels of extreme purity.
Reverse osmosis can be a water purification technology can be achieved by which a high percentage of contaminant retention, dissolved as well as undissolved (up to 99% retention of dissolved salts). When two liquids with different salt concentrations, are separated by a semi-permeable membrane, a pressure difference between either side of the membrane can be a function of the concentration difference can be established. This specific pressure, called osmotic, forces pure water pass off less concentration on the side of more concentration until the concentrations become equal.
Conversely, if the system applies a higher osmotic pressure as well as opposite, can be the pure water of higher concentration side which passes into the lower concentration. This specific phenomenon, which plays a key role inside the metabolism of all living cells, can be used as a method of desalination or demineralization, besides using very simple means.
So with equipment whose sophistication may increase depending on the required quality of water, or the type of controls you want to apply, we can get irrigation water through wastewater, potable water through brackish or sea water, water purified through drinking water network, etc.
The teams basically consist of:
- Conditioner Pretreatment
- Containers as well as reverse osmosis membranes
- Regeneration system
- Box protection, command as well as control
- Metering pumps for adding chemicals with low level sensor.
- Pre-filtration to 5 microns.
- TFC osmosis type membranes pigtail.
- High pressure pumps multistage type.
- Flow control valves in stainless steel.
- Flow meters as well as conductivity.
- Control pressure membrane as well as treated water.
- Automatic cleaning system as well as storage tank flushing.
- Control panel with display diagram, commanded by PLC
