Inactivation of phosphorous
using aluminum sulfate.
|
|
Aluminum hydroxide
(Al(OH)3) strongly binds to inorganic phosphorous resulting in a very stable
compound

|
*This treatment removes
both soluble P from the water column as well as P in the sediment. Wide
applicability.

|
Chemicals can be very
expensive, but if applied correctly one treatment is all that is necessary
for a long lasting improvement in lake water quality.
|
|
As some of you may be
aware, there was an alum treatment already done in the lake in 1988. This
treatment was not very successful because it did not have a long lasting
effect on 3MP water quality.
This was likely due�

|
INADEQUATE
APPLICATION: underdosed
overall, overdosed shallow areas, underdosed deep areas..
|
|
You also may have heard
that a buffering agent was responsible for the lack of success of the
treatment. Although a pipe did
leak, it is likely not the cause of the problem with the treatment.
|
|
Alum is not successful if
too little of the alum is added or phosphorus input into the water isn�t
altered, then the alum treatment has no lasting effects.
|
|
|
|
Learning from the previous
treatment and with advances in modern technology, application for
remediation in the future can be tailored to the specific needs of 3MP.
