WASTEWATER SECONDARY TREATMENT

From the primary settling tanks, effluent flows by gravity to the two trickling filters. each trickling filter consists of a round bed with various sized rocks. Primary effluent is sprinkled over the rocks and allowed to trickle through the bed. Bacteria and other microorganisms attached to the rocks oxidize organic material in the wastewater. The bacteria convert waste in the water to harmless biosolids.

   
  This is the final clarifier. Here, the water is processed and organisms are released into it to purify it.   This is the sludge thickener, where, obviously, the sludge is thickened as the water is evaporated out.
 
  These are the digesters, which process the solids so that they can be made into fertilizer. .     These are the chlorine tanks, where chlorine is released into the water to kill remaining bacteria before it is released into the East Branch of the Perkiomen Creek

Chemicals are used in purifying the water for human use. One such chemical is called cationic polymer. The polymer causes small, sticky particles named floc to appear in water and attract/capture dirt particles in the water. The weight of both the polymer and the dirt particles cause the combined mass to drop to the bottom during the sedimentation process . Chlorine is used to kill bacteria. Testing of the water is done constantly to insure the water being returned to the creek meets all of the requirements.

 
An in-house lab allows for constant monitoring of the water quality.    Several liquid samplers are used to test the water.
