In some rare instances, allergic reactions can occur following the administration of aminophylline. Signs of an allergy may include difficulty breathing, swelling of the face or limbs, and hives. Allergic reactions can escalate quickly and may require immediate medical attention. If a dog exhibits any of these symptoms after taking aminophylline, pet owners should seek emergency veterinary care.
Another physical process is filtration, which involves passing water through various media to remove suspended solids. Filters can be composed of sand, gravel, or advanced materials like activated carbon or membranes. The choice of filtration method depends on the specific contaminants present in the water and the desired quality of the treated water. Membrane technologies, such as reverse osmosis, are particularly effective for removing a wide range of contaminants, including dissolved salts and organic compounds.
