Ammonia nitrogen (TAN), a major pollutant in wastewater, consists of non-ionized ammonia (NH3) and ammonium ions (NH4 +), which are pH- and temperature-dependent. To determine its presence in water is important because of its harmful effects on both humans and aquatic organisms.
Eight cups, three liters, one gallon? Straight water or added vitamins and electrolytes? Everybody has an opinion on what it means to be hydrated. Drinking water every day helps regulate mood, keeps the body from overheating, and supports healthy skin and digestion. But staying hydrated without consistent access to clean drinking water can be a challenge.
What is a hydrophilic PCTE membrane?
Polycarbonate track-etched (PCTE) membranes are characterized by durability, low protein binding, controlled porosity, and surface smoothness. PCTE membranes come in hydrophilic and hydrophobic materials, which affects the membrane “wet-ability”. Wet-ability refers to the ability of a membrane to draw water into the pore structure.
