clhcolwell (4:22:17 PM): can we just talk here?
Taylor (4:22:42 PM): ok
clhcolwell (4:23:18 PM): ok .. we will talk here
clhcolwell (4:24:38 PM): question #1
clhcolwell (4:26:23 PM): what is the population that the OB treatment plant
services
clhcolwell (4:27:14 PM): estimate
Taylor (4:27:17 PM): I work for the City of D.B. and our plant the
Bethune Point Plant serves the Beach Side west to US1
clhcolwell (4:27:33 PM): how many people
Taylor (4:27:43 PM): the Pop in that area must be about 400,000 or more
clhcolwell (4:28:07 PM): is that typical for a municipal plant
Taylor (4:28:14 PM): that is an estimate
Taylor (4:28:47 PM): the flow thru our plant lately is 5.7 -6.00 million
gallions a day
Taylor (4:29:18 PM): if you figure 100 gallons per person that is a low
est.
clhcolwell (4:29:21 PM): can you briefly explain to us how the treatment
plant works
Taylor (4:29:38 PM): the water comes in and the water goes out
Taylor (4:30:12 PM): really the detinson time of the process is about 3
days
clhcolwell (4:30:26 PM): is the plant operating at capacity
Taylor (4:30:56 PM): no we have built for the future  and are currently
using 1/2 cap
clhcolwell (4:31:31 PM): does the load change seasonally?
Taylor (4:31:47 PM): yes
Taylor (4:32:17 PM): bike week spring break and other seasonal events
like speed weeks add flow
Taylor (4:32:45 PM): we do not have a heavy industrial waste stream
clhcolwell (4:32:46 PM): the amount of change is about?  the range?
Taylor (4:33:11 PM): 3 to 4 MGD
clhcolwell (4:33:24 PM): mega gallons per day
Taylor (4:33:33 PM): yep
clhcolwell (4:33:51 PM): how long before the capacity is reached
Taylor (4:34:17 PM): during the rainy season we will see the flows jump
to 24 mgd > million gallons a day
clhcolwell (4:34:57 PM): in five years we need a new plant?
clhcolwell (4:36:48 PM):  if there is a heavy rain or overflow,
what do you do with it?
Taylor (4:38:21 PM): it is processed along with the normal flow
clhcolwell (4:38:32 PM): what if it exceeds capacity?
Taylor (4:38:56 PM): we have a problem with solids carry over
clhcolwell (4:39:08 PM): can you explain?
Taylor (4:39:36 PM): that is the solids in the final clarifier leaves
the tank the wrong way .. which is over the weirs
clhcolwell (4:40:00 PM): where does the water flow once it leaves the tanks?
Taylor (4:40:40 PM): the clarified liquid usually leaves over the weirs
and procedes to the denight tank
clhcolwell (4:41:09 PM): denight tank ... please explain
Taylor (4:42:07 PM): there are different types of tanks this tank
removes  nitrogen and v ents it intothe atmosphere
clhcolwell (4:42:35 PM): what do you do with the processed sludge?
Taylor (4:43:44 PM): daytona has two plants one down on the H. river and
the other next two the Municipal Stadum
Taylor (4:44:17 PM): Bethune Point sludge is pumped to the Regional
Plant next to the Stadium  6+ miles
clhcolwell (4:45:13 PM): what do they do with it?
Taylor (4:45:34 PM): it is dewatered and from there it is hauled to land
disposal
clhcolwell (4:46:04 PM): is it incinerated or buried?
Taylor (4:46:17 PM): no
clhcolwell (4:46:36 PM): what happens to it?
Taylor (4:46:59 PM): land application in orange groves
Taylor (4:47:09 PM): also sod farms like it
clhcolwell (4:47:19 PM): fertilizers ... do you make an profits
Taylor (4:47:46 PM): no we pay to have it taken away
clhcolwell (4:47:56 PM): how much
Taylor (4:48:06 PM): and the farm intrests pay for it
Taylor (4:48:30 PM): there is a company called enviro acting as a middle
man
Taylor (4:48:42 PM): making a profit
clhcolwell (4:48:56 PM): what is the chemical makeup of the sludge?
Taylor (4:49:39 PM): not sure excatly
clhcolwell (4:49:50 PM): how can we find out?
Taylor (4:50:46 PM): Bob our chemist will have the answers down to the
smallest elements
clhcolwell (4:51:14 PM): can you please send us Bob's email address so we
can contact him?
Taylor (4:51:40 PM): yes
Taylor (4:51:46 PM): dont have it with me
clhcolwell (4:51:47 PM): thank-you ...
clhcolwell (4:52:15 PM): what does it cost to operate the plant per unit of
trearted waste
Taylor (4:53:28 PM): I will have to look into that Im not sure
clhcolwell (4:54:12 PM): what are the most cost intensive parts of the
process?
clhcolwell (4:54:37 PM): particularly in waste disposal ...
Taylor (4:55:43 PM): Electric we recently had students come by for a
tour of the plant .. You should plan to stop by in the future to see the
plant.
clhcolwell (4:56:56 PM): how much sludge is produced
Taylor (4:57:04 PM): we now have a $ 5,000,000 up grade on going
installing U V  for disinfection of the effluent
clhcolwell (4:57:48 PM): What would be the operating costs associated with
the UV treatement?
Taylor (4:57:51 PM): 4,000 +  Lbs of sludge leave the Bethune Plant
daily
Taylor (4:58:19 PM): it is very new tech. and will not be only till
1-1-2000
Taylor (4:58:30 PM): on line
clhcolwell (4:58:44 PM): So we could use this figure along with the 6 MGD
daily to get a ratio?
Taylor (4:59:25 PM): i believe so
clhcolwell (5:00:05 PM): EPA or DOE laws?  what guidelines do you have to
operate under?
Taylor (5:01:36 PM): EPA DER DEP  OSHA 
clhcolwell (5:02:01 PM): Dept Environmental ________
Taylor (5:02:16 PM): Protection
clhcolwell (5:02:18 PM): DER and DEP
Taylor (5:02:32 PM): enviromental regulation
Taylor (5:02:45 PM): enviromental protection
clhcolwell (5:02:49 PM): where can we get a hold of a copy of these
guidelines
Taylor (5:03:06 PM): there is a web site
clhcolwell (5:03:14 PM): URL?
Taylor (5:03:59 PM): no dont have that
clhcolwell (5:04:02 PM): what is the classification of the sludge ?  we have
heard about AA, A and B, I think
Taylor (5:04:29 PM): the class depents on how much treatment
clhcolwell (5:05:03 PM): what classification do you produce?
Taylor (5:05:21 PM): to spread it on land the sludge must be heated to
near  a hundred degrees
clhcolwell (5:05:55 PM): Fahrenheit ... is that A, AA, or B
Taylor (5:07:05 PM): the company which takes charge of the sludge after
it has been dewatered must process it to an exceptable degree and the lab
results will describe it  as class so and so  yes F
clhcolwell (5:07:48 PM): ok ... is that enviro that is doing the treating of
the sludge/
Taylor (5:07:59 PM): some times the sludge as in the past was only
dewatered and then placed in a land fill
clhcolwell (5:08:26 PM): but to use it as fertilizer it has to be heated ...
is that correct
Taylor (5:09:33 PM): yes we can find the limits described in state law
to which it must be processed
clhcolwell (5:09:52 PM): What is the environmental impact of just dewatering
it and placing it in the landfill ?
Taylor (5:10:01 PM): depending on the uses
clhcolwell (5:10:49 PM): we have an educational component in the contest,
what are the requirements for being a manager of a water treatment plant?
Taylor (5:11:35 PM): the landfill is a dead end application of the
sludge 
Taylor (5:12:15 PM): there are courses at DBCC
clhcolwell (5:12:34 PM): Can you get us a contact at enviro?
Taylor (5:13:18 PM): I can try, It is a large company having offices in
N.J.
Taylor (5:13:30 PM): and other regions around the country
clhcolwell (5:13:48 PM): thank-you for looking for us
clhcolwell (5:14:45 PM): do you know how much you have to pay enviro to ship
the sludge away?
Taylor (5:15:10 PM): no , it is in a five yr. contract I know that much
clhcolwell (5:16:07 PM): what does the UV treatment do exactly?
Taylor (5:18:09 PM): The light from the U.V. actualy cause the cell
walls of the micro organisms to be crushed It disinfects the effluent
leaving the plant so that the H. River is cleaner the bacteria are limited
clhcolwell (5:19:14 PM): what are you doing to clean up the effluent now,
until the UV comes in? 
Taylor (5:19:50 PM): We are using CL2  to disinfect
clhcolwell (5:20:09 PM): so how does that affect the river?
Taylor (5:20:49 PM): Years ago it was acceptable to leave the chlorine
in the effluent and place it in the receiving stream
Taylor (5:22:17 PM): but the last 12 years we have been dechlorination
with sulfier dioxide or sodium bisulfite
clhcolwell (5:23:06 PM): Are there other "leftovers" in the treatment other
than the effluent and sludge?
Taylor (5:23:41 PM): river study's tell us that the water we are placing
in the river is cleaner than the receiving stream
Taylor (5:24:39 PM): there are RAGS  the inorganics that are
collected on bar screening devices
clhcolwell (5:25:15 PM): what do you do with the RAGS?
Taylor (5:25:27 PM): and Grit  The "Daytona Beach" that is always
comming down the collection system and filling the tanks with sand
Taylor (5:25:50 PM): The rags are collected by screening devices and
sent to the land fill
clhcolwell (5:26:45 PM): Will the UV will be more efficient?  most cost
effective? how long before you recover the costs of its installation?
Taylor (5:26:51 PM): along with the grit which is also collected by a
device we call a tea cup
Taylor (5:27:55 PM): Waste water is kind of like NASCAR the faster you
want to go the more you have to spend.The cleaner we want our enviroment the
more we must spend the clean up the water.
Taylor (5:29:11 PM): U.V. is suppost to be comparable to Chlorine
clhcolwell (5:30:03 PM): by cost or by effectiveness?
Taylor (5:30:14 PM): The driving force to use U.V. is the Laws that will
go into effect next year.
clhcolwell (5:30:46 PM): so you have to change over?
Taylor (5:31:43 PM): The additional safety equipment and Scrubbers the
clean the air in a SPILL area of a chlorine spill are close to the costs to
convert to U.V. additionally public safety is a MAJOR concern.
clhcolwell (5:32:52 PM): so chlorine will not be allowed anywhere in florida
clhcolwell (5:33:00 PM): after 1-1-2000
Taylor (5:33:50 PM): The Public will be notified if they live in a area
of close to the use of chlorine and that will satisify the requirments of
the law
clhcolwell (5:34:35 PM): what are the energy requirements of the UV lights?
Taylor (5:36:06 PM): we will be using a 12 kw generator to power the uv
system in an event of a black-brown out
clhcolwell (5:37:03 PM): electrical is your greatest expense
Taylor (5:37:10 PM): we also will have battery back  ups system
clhcolwell (5:37:11 PM): do you know any breakdowns?
Taylor (5:37:30 PM): yes there are blowers motores conveyer belts etc
etc
Taylor (5:37:49 PM): breakdance
clhcolwell (5:39:08 PM): how much is the electrical bill per month?
clhcolwell (5:39:23 PM): (last question ... promise :-))
Taylor (5:39:47 PM): we have spare motors and other stand by componets
to avoid going out of compliance
Taylor (5:40:45 PM): I dont handle the electrical bill but I know we can
save 4 to 5 hundred a month by turning off one one-hundred horse
electrical motor driving a blower
Taylor (5:41:02 PM): FPL LOVES US
clhcolwell (5:42:05 PM): WOW!!  you have been WONDERFUL!  and we deeply
appreciate your time ... I hope that you won't mind if we write to ask you
some more questions ... and to remind you of some of the requests that we
made earlier in this session ...
Taylor (5:42:07 PM): We have a generator They ask us to fire up and
provide electricity to the grid in the summer months when demand is high
clhcolwell (5:42:51 PM): so FPL buys power from you during the summer?
Taylor (5:42:57 PM): yes
Taylor (5:43:17 PM): actualy they credit our account
clhcolwell (5:43:30 PM): that's cool
clhcolwell (5:43:43 PM): Brad ... thanks
Taylor (5:43:48 PM): have a happy Thanksgiving
clhcolwell (5:43:50 PM): I know that this has been a long experience
clhcolwell (5:44:09 PM): there were 20 students involved in this session ...
clhcolwell (5:44:17 PM): you have answered all of their questions
clhcolwell (5:44:30 PM): they are exhausted ... as I am sure you are too
Taylor (5:44:45 PM): God Bless every one Good Luck with your studys
clhcolwell (5:44:51 PM): I'll stay in touch
clhcolwell (5:44:57 PM): thanks again
clhcolwell (5:44:58 PM): bye

Subject: Brad taylor's response

got a letter back from Brad Taylor saying that all the tanks in the bPP are
used in parallel, andrated at a maximum of 20mgd

I was wondering if maybe you could tell us if the multiple tanks (the
aerations, 6 final clarifiers, and 2 anoxic) if they are in parallel or in
series? These tanks are are all seperate  we use them as the flow rises and
falls. They are placed into operation when needed.  We have 4 aeration tanks
& 6 clairifiers. The anoxic tanks work together as one unit there are two of
these and one anarobic tank. at the begining of the process where the raw
wastewater and the return sludge is mixed.

In other words, does the sewage separate to enter multiple tanks at once or
does it go through, for example, final clarifier #1 then final clarifier #2,
etc? The sewage is separated and flows to tanks that are on line.  The flows
into the clairifiers are both entering the tanks as sludge and exiting the
tanks as return sludge and clarified effluent.  Waste sludge is removed from
the system as well.

If in parallel, could we combine the tanks to form one massive tank? Thats
pretty much how they work right now.  To control the flows we simply place
another twin tank on line.

Also, are all of the tanks at your plant required to process 5 million
gallons per day?  Or, are some there for future expansion? The plant is
rated at 10 million gals a day .  However it can handle flows at 20 MGD.  The
enginers are always upgrading wastewater plants and I am sure that they will
be getting back to the drawing boards in the future with an upgrade.  For
now there is no need to expand the plant.It was upgraded just 6 yrs. ago and
should not need any new tanks for awhile.

Good Luck
Brad Taylor

Do any of the tanks have to be open for evaporation?  Could they all be
sealed?  No .  The only tanks I can think of which may require evaporation
would be sludge drying beds .  They are only about 8" in heighth. We do not
use these in our process because of the odor,  and we are right in the middle
of town.

Are any of the containers' shapes critical?  sizes?  Our clarifiers are
rounded to provide for the rake arm on the bottom of the tank and the skimmer
on the top.  The floor of the tank is sloped to allow the sludge to easily be
picked up off the bottom of the tank.

Contact tanks could be as long as 75 yards thats why they built with common
walls between the runs. So to save space and money they are built as one
rectangler tank and divided up into sections.

Here are some monthly  kwh and the cost of the electricity for the year 1999
I do not have a break dow by equipment.

April  339,200 = 18,275.53
May  406,720  =  21,229.34
June  376,880 =   18,495.64

Sept  358,320  =  16,496.40
Oct    351,520  =  16,913.68

1)  We also need to know the land area of the plant.  16 ACRES The amount of
surface area covered by the tanks .DONT HAVE THAT WITH ME .. the kids tell me
that there appears to be something like a landfill (or at least undeveloped land to one side .THIS
PROPERTY IS OWNED BY THE STATE OF FL AND WILL BE USED TO DREGE THE
INTERCOASTAL WATERWAY  "HALIFAX RIVER"..IT IS A DEWATERING LAGOON

please do not include that acreage in your answer).I DID NOT.
it is very important that we can compare the areas of your plant with ours.

(2)  Could you also give us an indication/breakdown of where the majority of
the upgrade costs have gone into .ENGINEERING FIRMS - CONSTRUCTION OF TANKS
BACK IN 94 THROUGH 98...ELECTRICAL WORK SUPPLYING POWER TO NEW TANKS
.YARD.PIPPING  GETTING THE FLOW TO THE TANKS  THE UP GRADE BACK IN THE 94-98
YEARS WAS ABOUT 16 MILLION  I DONT USUALLY KEEP TRACK OF THE SPENDING .  IT
USUALLY IS HANDLED ON A MUCH HIGHER LEVEL THAN MINE.  THE SPENDING MUST BE
APPROVED BY THE CITY COMMISION AND ENGINEERS AND STUDYS HAVE TO BE MADE ..
ITS QUITE A LONG PROCESS. ..
additional tanks, UV equipment,
plumbing, land development .... .

(3) What company supplied/built your tanks? MANY COMPANYS OVER THE LAST 
THIRTY YEARS  THE CONSTRUCTION COMPANYS MAY NOT BE IN BUSNESS ANY LONGER.. I
THINK ONE OF THE COMPANYS WAS WED CONSTRUCTION OUT OF JACKSONVILLE AND
ANOTHER WOULD BE INDIAN RIVER CONSTRUCTION, I THINK JACKSONVILLE AS WELL.
