1. How does MECO's LWP treat all sources including seawater, brackish water and NBC contaminated water?
|
|
|
|
< Back to Top
Most conventional military water treatments only treat one type of water, i.e. freshwater with minor contaminants. The key to the MECO's LWP is membrane-based filtration, which filters out all dissolved ionic material (i.e. seawater) and particulate matter (i.e. baterica, e coli, virsuses). Automated processes and controls eliminate the use of chemicals for operation.

2. Is filtration necessary in the feed to a RO unit?
|
|
|
|
< Back to Top
Yes, small particulate matter will embed itself into the first element of the RO array. This will reduce the life of this element, as well as increase the pressure drop through the RO unit.

3. Is there any benefit to using Membrane Filtration instead of the standard multi-media filtration?
|
|
|
|
< Back to Top
The Membrane Filter removes suspended solids down to .01 micron, as well as other contaminants such as bacteria and some viruses. Multi-media filters (MMF) / cartridge filters will only remove suspended solids to approximately 1-5 micron. When feeding an RO unit, the MF system will significantly reduce the bio-fouling, as well as reduce the SDI to below 1.
