Eco-Friendly RO Water Purifier Plant Reverse Osmosis Pretreatment System
1. Features
Reverse Osmosis Systems provide high-purity water solutions that lower costs, increase efficiencies and help drive profitability by:
2. Company Profile
KANGWEI ENVIRONMENT ENERGY GROUP(KWEE), like a shining pearl ,located alongside the beautiful sight of TaiHu lake of Wuxi in China. KWEE has engaged in design and production for more than 20 years, With the many years accumulated mature development, the business range had included the large power diesel engine generator set and relevant auxiliary fuel oil system equipment as well as the environment protection
KWEE specializes in designing, manufacturing and installing
customized, cost-effective reverse osmosis and ultrafiltration
systems, ranging from 70 litres per an hour to several hundred
thousand litres per day. We manage all water treatment projects
from start to finish; from site evaluation, water analysis,
in-house design, installation, commissioning, scheduled maintenance
and on-going technical support.
3.1 Distillation
Removes lead, nitrate, sodium chloride, pesticides, organic compounds; • System cost: $300 (counter-top) - $1700(automatic), plus electricity to run. A distillation unit works by evaporating water and collecting the steam that is produced. Impurities in the water are left behind. Distillation can remove lead, nitrate, sodium chloride, and many pesticides and organic compounds. Distilled water often has a flat or bland taste, due to the removal of minerals.
3.2 Reverse Osmosis
• Removes radium, sulfate, calcium, magnesium, potassium, nitrate, fluoride, phosphorous; • Removes some pesticides and organic compounds; . In the reverse osmosis process, water passes through a semi-permeable membrane which removes inorganic minerals like radium, sulfate, calcium, magnesium, potassium, sodium, nitrate, fluoride, and phosphorous. It also helps to remove some organic compounds including some pesticides. Often, reverse osmosis units are used in combination with a mechanical filter and an activated carbon filter. The water passes through the mechanical filter first, where sand and large particles are removed, then through the reverse osmosis unit, and lastly through the activated carbon filter which removes organic compounds. Reverse osmosis units are relatively expensive to install, and use large amounts of water. Anywhere from four to nine gallons of water are required for every gallon of treated water produced. Water should be tested periodically to make sure the membrane is intact and properly functioning.
3.3Chlorination
• Kills bacteria and some viruses (Note—does not kill Cryptosporidium, Giardia, and some other microscopic organisms); • Removes some bad odors, tastes and colors; Chlorine added to water kills most bacteria and some viruses. Water can be chlorinated in two ways: a “shock” chlorination in which a strong chlorine solution is pumped through a well or plumbing system to kill bacteria on a one-time basis; or chlorine is added continuously through a chemical feed pump to constantly kill bacteria. Shock chlorination is usually used when a pump or well has just been installed to kill bacteria that may have been on the pipes or installation equipment, or if a well has become contaminated by a faulty cap or seal. Continuous chlorination is used when the source of the bacteria in the water cannot be eliminated.
3.4 UV Radiation • Kills bacteria, some viruses; This type of water treatment uses a mercury arc lamp to kill pathogens in the water. UV radiation kills most bacteria and some viruses, but is ineffective against cysts (such as Giardia) and worms. Cloudy or turbid water can reduce the effectiveness of UV radiation.
KWEE has vast experience in this specific field and has equipped many drinking water treatment systems.
