Rhinella lindae Rhinella lindae Rhinella lindae is a species of toad in the family Bufonidae. It is endemic to Colombia and known from its type locality, Murri in the municipality of Frontino, and from , both on the western slope of the Cordillera Occidental, Antioquia Department. The specific name "lindae" honors , an American herpetologist. However, common name Murri beaked toad has been coined for this species. The holotype, an adult female, measures , whereas the paratype male—of unknown maturity status—measures in snout–vent length. The snout is long and acuminate. In the female, tympanic annulus is present but the tympanic membrane is
Membrane operating conditions, cost and performance, it should prevented, and if necessary, removed. Optimizing the operation conditions is important to prevent fouling. However, if fouling has already taken place, it should be removed by using physical or chemical cleaning. Physical cleaning techniques for membrane include membrane relaxation and membrane backwashing. Chemical cleaning. Relaxation and backwashing effectiveness will decrease with operation time as more irreversible fouling accumulates on the membrane surface. Therefore, besides the physical cleaning, chemical cleaning may also be recommended. They include: Optimizing the operation condition. Several mechanisms can be carried out to optimize the operation conditions of the membrane
