Suspended solids are allowed to pass through Microfiltration Ultrafiltration Nanofiltration All of these

The question seems to be asking which of the following filtration methods allow suspended solids to pass through: Microfiltration, Ultrafiltration, Nanofiltration, or all of these.

1. Microfiltration: This is a type of physical filtration process where a contaminated fluid is passed through a special pore-sized membrane to separate microorganisms and suspended particles. Depending on the pore size of the membrane, some suspended solids may be allowed to pass through.

2. Ultrafiltration: This is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This means that most suspended solids are not allowed to pass through.

3. Nanofiltration: This is a relatively recent membrane filtration process used most often with low total dissolved solids water such as
