do water softeners remove lead

1 micron. UF system suppliers categorize each UF product as having a particular molecular weight cutoff (MWC), which is a rough dimension of the size of impurities removed by a given UF system. A 100,000 MWC UF membrane layer indicates that when water containing a provided typical substance with a molecular weight of around 100,000 daltons is fed to the UF device, almost all of the substance will not travel through the membrane layer. Compounds with a molecular weight of 100,000 daltons have a dimension of about 0. 05 microns to regarding 0. 08 microns in size. Suspended solids as well as solutes of high molecular weight are maintained, while water as well as low molecular weight solutes go through the membrane layer. Ultrafiltration is not essentially different from reverse osmosis, microfiltration or nanofiltration, other than in terms of the size of the particles it keeps. Ultrafiltration (UF) is made use of to remove basically all colloidal fragments (0. 01 to 1. 0 microns) from water as well as some of the largest liquified pollutants. The pore size in a UF system is generally responsible for identifying the type as well as dimension of contaminants removed.
