All types of wastewater treatment equipment require regular maintenance to keep running efficiently. Make sure you understand the cost and responsibility for this maintenance before buying.
Water Purification
There are a number of different techniques used for water treatment. These can include physical, chemical, and biological processes. The aim is to remove harmful materials from the water, making it suitable for use in industrial and medical applications.
Physical methods of purification usually involve mechanical filtration. This can take the form of sand or charcoal filters that physically separate the particles from the water. Chemical methods use chemicals to change the structure of contaminants, making it easier to remove them from the water. Other forms of used water treatment equipment for sale may include disinfection, granular activated carbon (GAC), ion-exchange, and UV sterilization. Disinfection uses chemicals such as chlorine and chloramines to kill bacteria. This method can also be used to eliminate heavy metals and organic compounds.
Surplusrecord
Surplusrecord systems are a great choice for those with limited access to fresh water. They also can be used to desalinate seawater and create drinkable water on a large scale, making them one of the most effective forms of water filtration available.
This filtration process uses a semi-permeable membrane to force water through, leaving out impurities and creating healthier, more nutritious drinking water. The RO system typically includes a sediment filter, carbon prefilter, reverse osmosis membrane, and post-carbon filter to prevent clogging of the final product. Aside from its use in industrial settings, osmosis is commonly found in nature; maple syrup makers use it to concentrate the sugary sap and the dairy industry uses it to separate milk and whey. On a smaller scale, osmosis is what makes drinking water taste so good in places that don’t have as many strict standards for tap water. The osmosis process works because water molecules are always trying to find an equal balance.
Oil Separator
A trap oil separator is a multi-chambered tank used in garages, cleaning plants and other facilities that discharge wastewater that may contain motor oils, transmission fluids, hydraulic oils, greases, etc. They are designed to help protect stormwater systems and the environment by preventing these oils and greases from being released into the waste stream.
When water enters the separator, a baffle reduces water turbulence and allows oil particulates to collect on one side while the other side of the baffle is trapped by wastewater. Then, the floatable droplets of oil are separated from the water by gravity while any solids that remain are collected by the baffle and routed to a coalescer. In order to keep your Oil-Water Separator working optimally, the sumps must be cleaned regularly. Typically, this can be done using a vacuum truck with a large volume hose that sucks the oil and debris from the separator into its tank for proper disposal.
