Abstract[edit | edit source]
This page is intended to be a hub and portal on the subject of Total Suspended Solids. At this time it focuses on the Arcata marsh in Humboldt County California. It is intended for anyone interested in the subject. Anyone may add data, summit analysis or provide insight to the issues; however, please keep in mind that people of all educations are encouraged to participate in this page. Incomplete information or ideas need to get stated on occasion, so they can be discussed, corrected or developed.
Data[edit | edit source]
Explain Math
- Concentration (C) measured in milligrams per liter (mg/l)
- Mass (M) measured by the flow rate (Q) in millions of gallons per day (MG/day) times the C
This is a small data set comparitively to the entire existance of the WWTF.
Is it repesentitive?
If so:
- It shows that the enhancement wetlands are a vitial component to the functionality of the treatment system.
Question:
- What causes the flucuations?
How is it being measured?[edit | edit source]
Design Flow[edit | edit source]
- Average: => Q = 2.3 MG/day
- Wet Seassion: => Q = 5.9 MG/day
What are the permit limits?[edit | edit source]
