C3) DEFINITION OF TECHNICAL TERMS
Diaphragm pump
Has good suction lift characteristics, some are low pressure pumps with low flow rates;others are capable of higher flows rates, dependent on the effective working diameter of thediaphragm and its stroke length. They can handle sludges and slurries with a relatively highamount of grit and solid content.
It is a positive displacement pump that uses a combination of the reciprocating action of arubber, thermoplastic or teflon diaphragm and suitable non-return check valves to pump afluid. When the volume of a chamber of either type of pump is increased (the diaphragmmoving up), the pressure decreases, and fluid is drawn into the chamber. When the chamberpressure later increases from decreased volume (the diaphragm moving down), the fluidpreviously drawn in is forced out. Finally, the diaphragm moving up once again draws fluidinto the chamber, completing the cycle.
Wastewater Glossary

Activated Sludge: Sludge that has undergone flocculation forming a bacterial culture typically carried out intanks. Can be extended with aeration. See Extended Aeration .
Advanced Primary Treatment:
The use of special additives to raw wastewater to cause flocculation or clumping to helpsettling before the primary treatment such as screening.
Advanced Wastewater Treatment Any advanced process used above and beyond the defacto typical minimum primary andsecondary wastewater treatment.
Aeration the mixing or turbulent exposure of water to air and oxygen to dissipate volatile contaminantsand other pollutants into the air.

Subsurface Flow Wetland (SF) A type of constructed wetland in which primarily treated waste flows through deep gravel orother porous substrate planted with wetland vegetation. The water is not exposed to the air,avoiding problems with odor and direct contact.
Suspended solidsthe small solid particles in water that cause turbidity. Particles of suspended sediment tendto settle at the channel bottom, but upward currents in turbulent flow counteract gravitationalsettling.
TDS - Total Dissolved Solids
Total Dissolved Solids (TDS) is a the combined total of all dissolved solids in wastewater,both organic and inorganic and very fine, such as colloidal minerals. Generally particles mustbe smaller than two micrometers to be considered a dissolved solid. For example, saltdissolved in water is a dissolved solid. Therefore TDS will "survive" screening or othercoarse filtration.

Tertiary TreatmentThe use of filtration to remove microscopic particles from wastewater that has already beentreated to a Secondary Level. Anthracite coal is the filter medium used by the MWWD.
Toxic pollutant those pollutants or combinations of pollutants, including disease-causing agents, which afterdischarge and upon exposure, ingestion, inhalation or assimilation into any organism can, onthe basis of information available, cause death, disease, behavioral abnormalities, cancer,genetic mutations, physiological malfunctions or physical deformation in such organism ortheir offspring. The quantities and exposures necessary to cause these effects can varywidely.
TreatabilityHow treatable a water sample is with a given substance. The "treatability" of Floccin™ isvery high with a wide array of wastewater types. The more treatable wastewater is, thebetter, obviously. All wastewater is treatable, how easy it is varies. The treatability can betested using samples in a "jar test". A small water sample is taken and placed in a jar. Thenthe flocculant or other treatment additive mixed in and the results observed. Treatability testsare an important part of wastewater optimization.
Total Coliforms
include bacteria that are found in the soil, in water that has been influenced by surface water,and in human or animal waste.
