Rhywun yn gwybod beth yw "sludge liming" yn Gymraeg plis?
"The addition of alkaline chemicals, mostly lime, as a stabilization method
is widely used within wastewater treatment plants (WWTPs). Liming raises the
pH of the sludge. At a pH of 12 or higher, pathogens and microorganisms can
be either inactivated or destroyed provided that adequate mixing and
sufficiently long contact times are realised."
Diolch
