[2] [3] [4] The term dialysis was first routinely used for scientific or medical purposes in the late 1800s and early 1900s, pioneered by the work of Thomas Graham. The first mass-produced man-made membranes suitable for dialysis were not available until the 1930s, based on materials used in the food packaging industry such as cellophane.

This combination of the two digestates consists as a sludge form. The liquid fraction constitutes up to 90% of the digestate by volume, contains 2–6% dry matter, particles <1.2 mm in size, and most of the soluble nitrogen and potassium, while the solid fraction retains most of the digestate phosphorus, and contains dry matter content ˃ 15%.

Indigestion, also known as dyspepsia or upset stomach, is a condition of impaired digestion. [2] Symptoms may include upper abdominal fullness, heartburn, nausea, belching, or upper abdominal pain. [3] People may also experience feeling full earlier than expected when eating. [4]
C + 2 H 2 SO 4 → CO 2 + 2 SO 2 + 2 H 2 O S + 2 H 2 SO 4 → 3 SO 2 + 2 H 2 O. Catalysts like selenium, Hg 2 SO 4 or CuSO 4 are often added to make the digestion go faster. Na 2 SO 4 or K 2 SO 4 is also added to increase the boiling point of H 2 SO 4. Digestion is complete when the liquor clarifies with the release of fumes. [3] A distillation ...
The French scale measures and is proportional to the outer diameter of a catheter, with 1 French (Fr) defined as 1 ⁄ 3 millimeter, making the relationship: 1 mm = 3 Fr. Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. [ 2 ]
