Initial Bench Treatability Test – ORL Waste Process Water

 

The initial waste washing and process water was collected by Ken Gardner of N.E.A.T. Environment™, Inc. ( NEAT ). The samples were taken to International Metallurgical and Environmental Inc. ( IME ) laboratory, where the raw waste water heavy metals analysis was done. 

 

The KB-1 treatment was completed by Ken Gardner and personnel at IME. The metallurgical lab completed lab analysis on the raw wastewater and KB-1 Treated samples of the waste process plating water.  This KB-1 treatment work was done on Wednesday, 3 April; with the lab analysis being completed the following 2 days on the KB-1 treated waste water.

The sample bottle was opened and a 125 ml sample was taken by IME Lab Technician to provide the “Raw Water” metals analysis and pH reading.  This raw water analysis was done in order to provide treatment guidelines on how to treat with the Keeco SME product using KB-1.

 

Once the raw water analysis was done, a 1 liter sample from the same sample bottle and was placed in a large beaker. The following observations were made :

 

1.                  The water was a dark blackish / gray colour with organic solids floating and a light hydrocarbon sheen.  The water had an extremely bad odor.

2.                  Water was allowed to settle for 1 hour.  There was limited settlement of particulate to the bottom of the beaker.

            pH adjustment to the raw water in order to treat with KB-1

 

9:40     pH adjustment was done with 3.0 mg  HCL acid,                                  pH 4.05                      

as the HCL was added it was magnet stirred, with

pH monitored continuously. 

            As pH 4.02 was obtained, the water remained the same colour

            With a light flock produced.  The heavy odor subsided slightly.

 

9:55     pH remained at pH 4.05, so with the water stabilized, then

the sample was ready to start the SME Treatment using KB-1.  pH 4.00            

 

Start KB-1 Treatment :     Time 10:05 a.m.

 

                        Treatment Description                                                          pH

                       

9:55     Starting with 25 ml of tap water, 0.5 grams of KB-1                             

            was mixed into a slurry.  Then slowly added to the

            1 – L. ORL water sample, with continuous magnetic

 stirred agitation.                                                                                   pH 4.74          

 

10:05   Sample had been allowed to settle.  At this time the sample

            is agitated and reading were taken.                                                        pH 5.11          

 

10:10   Starting with 25 ml of tap water, 0.5 grams of KB-1                             

            was mixed into a slurry.  Then slowly added to the

            1 – L. ORL water sample, with continuous magnet

stirred agitation.                                                                                    pH 5.21          

 

10:15   At this time the sample is agitated and reading were taken.                     pH 9.33          

            A light gray/black flock has formed and settled quickly to the

            Bottom of beaker.  With the flock settled, the water is clearing.

10:25   Treatment sample pH reading was taken                                               pH 10.33

 

pH has risen rapidly, suggesting that the second KB-1 addition should have been

only 0.25 gram/liter to the waste water.

 

           

10:35   Treatment sample was agitated and pH

            readings was taken while sludge was in suspension.                               pH 10.84        

 

KB-1 treated sample was allowed to settle for 3 hours.

 

The following picture will provide the visible evidence of how the water had reacted to the SME KB-1 treatment.  Changing water colour and pH with just 1.0 gram / liter of KB-1 to treat the raw water.

Clear water decant sample taken – 3 hr. Into KB-1 treatment for lab analysis

 

2:25     Treatment sample pH reading was taken of the clear water.                               pH 10.64

           

At this time the KB-1 treated sample was poured into a vacuum filter with a shark skin filter to filter out the precipitation material from the treated water.  Below, is the IME Certificate of Analysis lab analysis of the KB-1 Treated water is shown.

Lab Analysis after 4 hours Reaction time with KB-1.

 

From the above results, we believe that the treatment process can be developed to insure encapsulation of the metals present in the Radiator Repair Shop Waste Wash and Process Water to discharge standards with a safety margin.  From the initial lab tests and KB-1 treatment of 1.0 grams per Liter of KB-1, it can be assumed that this treatment would be economical.  Estimate sheet is attached to this report for review. 

 

It is suggested that an additional two bench treatability lab tests and KB-1 treatment processes be completed on two samples, each of different OLR Waste Water and Process water.  From these additional lab bench tests, Keeco can verify the treatment procedures, amount of KB-1 required and compliance with the City of Kelowna Discharge Standards for KB-1 treated water. 

 

Due to very limited amount of KB-1 Sludge, we were not able to provide a BC MOE SWEP Leachate Test.  Provided that NEAT was to complete another 2 to 3 bench tests, then the Sludge SWEP could be done.
