Case Study 2-Arizona Facility
Extended Aeration |
|
|
|
Background Data: |
|
Case Study: Wastewater Treatment |
|
Location: Arizona Facility Type: .Extended aeration with two 74
million gallon lagoons |
|
Designed Flow: 8.0MGD |
|
Current Flow: 6.5 MGD |
|
Challenge: |
|
To determine if Natural Resource Protection Corporation and PX700
could accomplish the following: |
Reduce solids generated
|
Reduce algae formation
|
Improve effluent quality
|
|
Facility personnel were used to gather appropriate data.
|
|
Treatment Procedures: |
|
Product Used: PX700 TM |
|
Treatment Period: 6 weeks |
|
Amount of Product Used: 6.5 gallons daily via injection
|
|
Amount of Product Used: 220 gallons via aerial application to
lagoons |
|
Injection Points: Two at lower lagoon headworks |
One at midpoint lower lagoon at aerator
|
Two at headworks/transfer point upper lagoon
|
One at midpoint upper lagoon at aerator
|

The use of PX700TM controlled biosolids production, keeping
effluent well within standards, and also controlled algae growth
and reduced sludge volume. An additional benefit of the use of
PX700TM was a reduction in the wear on aerators and control pumps
