Filtration: A slow sand filter, pressurized rapid sand filter, or pre-coat filter is the next step in treatment to filter out as many of the blue-green algae cells as possible before the water enters the disinfection system. ï Pressured rapid sand filters are the most common filters used for drinking water ponds.
Reactive urothelial cells and severe, mostly chronic inflammation. -- Urothelial cells, a type of epithelial cell found only in the urinary tract, line the urinary tract and they become reactive (changed) when injured by inflammation.
â¢ Transitional epithelial cells, or urothelium, are cells found in the ureter, bladder, and renal pelvis. These cells consist of multiple layers that expand or contract such as in the case of the bladder when it is full. They work to accommodate liquid volume and protect against the effects of the urine.
