Adsorption   of DNA to sand and variable degradation …

Adsorption of DNA to sand and variable degradation …

Adsorption and desorption of DNA and degradation of adsorbed DNA by DNase I were studied by using a flowthrough system of sand-filled glass columns. Maximum adsorption at 23 degrees C occurred within 2 h. The amounts of DNA which adsorbed to sand increased with the salt concentration (0.1 to 4 M NaCl and 1 mM to 0.2 M MgCl2), salt valency (Na+ less than Mg2+ and Ca2+), and pH (5 to 9).

Water purification using sand | SpringerLink

Abstract. Slow sand filters are used to purify drinking water. Each filter consists of a large tank containing a bed of sand through which water passes at typical rates of 0.1–0.3 m h −1.Water is cleaned by physico–chemical and biological processes occurring at the air–water interface, within the bulk water, over the surface of the sand, and within the bed of sand.

2019-9-27 · Sand bed filters are an example of a granular loose media depth filter. They are usually used to separate small amounts ( 10 parts per million or 10 g per cubic metre) of fine solids ( 100 micrometres) from aqueous solutions.: 302–303 In addition, they are usually used to purify the fluid rather than capture the solids as a valuable material.
