A cross-connect is any connection between facilities provided as separate units by the datacenter. In other words, if you rent a cage, you can run cables betweeen your various racks and they are not really considered cross connects. But typically a user facility is a rack. Consider the uplink to a network provider. The line that runs from you to the telco's rack is a cross-connect. Any other between-rack cable run falls in this category. Even if the datacenter is bundling network access, it's still a cross-connect. (It's also typical to have a meet-me room that is the center of all the cross-connects, it's a patch-panel room or cage.)
Water recycling is the process of taking effluent (wastewater and sewage) and treating it so that it can be reused. For potable (drinkable) use, the recycled water has to be treated to a sufficiently high level that it's suitable for human consumption.
The only healthy and safe way to drink ordinary tap water is to use a water purification. Chemical Sources. Chemicals will enter into tap water from many different types of sources. Pollution is one way that chemicals have gotten into the tap water supplies.Other ways are when chemicals are added to the water by the public water systems. The most common of these chemicals is chlorine. Chlorine is the most common of the types of chemicals currently being used to treat public water supplies.It is used to remove and to kill any bacteria which could be living in the water.ver time, chlorine taken in small doses will increase the risk of cancer, heart disease and other health conditions. Most all public drinking water systems use chlorine to purify water. Other chemicals which are found in drinking water are equally as deadly.
