Atelopus pachydermus and mean "thick skin". Common name Schmidt's stubfoot toad has been coined for this species, in reference to Eduard Oscar Schmidt who described the species. An alternative common name is Oyacachi jambato toad. Adult males measure and adult females, based on two specimens only, in snout–vent length. The snout is acuminate. The tympanic membrane is absent. The fingers have no webbing whereas the toes are webbed. The dorsum is covered by widely scattered or dense well-defined, rounded warts. The dorsum is yellow and has a dark brown pattern of marks, blotches and/or lines. The venter is white, sometimes orange or
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
