... is an event that takes place in the biological and industrial world. Marine biological systems annually process 6.7 gigatons of “Si”. In industry, silica is used for a plethora of applications (filler, drug excipient, catalyst support, etc.), but in water treatment systems it is a problem, as it forms...

... silicate usually precipitates in fluids of higher temperatures. ⁴ Abstract Metal silicate deposits have been noted in several water treatment facilities, but they are more common in geothermal systems. Herein, chemical approaches for the inhibition of metal silicate formation will be presented...
