New : "Blue NITE" Process for
Denitrification
 Hayden,
ID -- Blue Water Technologies, Inc. expands its Blue PRO®
wastewater nutrient removal product line with Blue NITE™ for
denitrification. Blue NITE™ allows municipalities to meet
permit levels for discharge of wastewater by lowering
nitrate to less than 3 mg/L N. Blue Water has installed
seven (7) Blue NITE™ systems in the New England states area.
High levels of nutrients in
wastewater can lead to a degradation of water quality by
algal growth and dissolved oxygen depletion. For this
reason, dischargers face increasingly stringent permit
limits for discharge of nutrients to receiving waters. Blue
Water helps wastewater dischargers meet their permit levels
by removing both phosphorus and nitrate in the same
treatment step. While phosphorus is removed by adsorption,
nitrate levels are lowered by a biological denitrification
process.
Blue Water’s acquisition of
Applied Process Technology, Inc. in September 2006 broadened
Blue Water’s product offering, adding the Centra-flo™ Filter
line. This product is a well-established gravity sand
filtration system with more than 250 installations
worldwide. The Blue NITE™ denitrification process, which is
explained in detail below, is accomplished in a Centra-flo™
continuous backwash, upflow sand filter by growing
fixed-film, heterotrophic, denitrifying bacteria within the
filter.
Blue NITE™ Process
To accomplish denitrification,
water is dosed with a carbon source as it enters the Centra
flo™ Filter. The water passes upward through the filter
media, where nitrate is converted to atmospheric nitrogen
(N2) by the bacteria. A portion of filtrate passes through a
sand washer, carrying contaminants and excess bacteria with
it. The washer separates solids, which are directed to a
reject line. The clean sand then falls by gravity back to
the media bed.
Nitrogen gas is produced during
operation and becomes entrapped by the filter media. This
gas is carried down with the sand and is released in the
sand washer. Some of the advantages of this method of gas
removal are: (i) no false readings of headloss; (ii) the
flow of the filter does not need to be reversed; and (iii)
the reject stream can be routed back to the head of the
plant, adding alkalinity for nitrification.
Results
Blue NITE™ is currently
installed at several locations in the U.S., lowering nitrate
levels to 3 mg/L N or less. In a current, full-scale
demonstration project Blue NITE™ has lowered nitrate from 10
mg/L N to less than 0.3 mg/L N. Concurrently small amounts
of nitrite (0.5 mg/L N) and ammonia (0.8 mg/L N) were
lowered to less than 0.015 mg/L each.
The process is able to
accommodate high or fluctuating influent nitrate levels.
Alternatives to methanol may be used for the carbon source.
The process applies to wastewater or groundwater
applications. Blue NITE™ may be run concurrently with Blue
Water’s Blue PRO® process for 90% or greater removal of
phosphorus, achieving total nutrient reduction in the same
vessel.

Superior Dewatering Performance
for Sludge
 Helsinki,
Finland -- A well executed water conditioning stage to
minimize sludge volumes paves the way for a successful
dewatering. Handling sludge in a sustainable manner reduces
volumes, decreases costs and makes the sludge odorless and
hygienized. Kemira Water knows how to help the customers to
manage this with the support of the patented solution Kemira
KemiCond®.
The
sludge challenge: The costs for sludge treatment – in terms
of manpower, equipment and energy – accounts for about 50%
of the overall cost of wastewater treatment. Moreover, most
end users require that the sludge is transported to another
destination. Therefore, it’s of great importance to increase
the dry substance (DS), thereby reducing volumes and, in
turn, cutting transportation and disposal costs.
The
environmental debate puts wastewater plant operations under
pressure to handle the sludge in a sustainable manner – and
naturally according to current laws and regulations. The
need for sustainable treatment technologies and careful
managing of our most valuable asset – water – is greater now
than ever.
The
treated sludge can be used in different ways – for
agriculture, landfill, production of soil products and for
incineration.
The
answer to the sludge challenge: The basic idea of Kemira
KemiCond® is to improve dewatering by breaking down the
water retaining structures that are formed in sludge. The
solution is a fully automated continuous process, ensuring
smooth operation and minimum “workload” requirement.
KemiCond® also decreases the customers’ operational costs
through minimizing the sludge volumes.
In
partnership with the customer Kemira Water takes full
responsibility for process design, assists in equipment
installation, performs operator training and carries out
maintenance services and cares for the supply of
conditioning chemicals. For the mechanical dewatering stage
Kemira Water has assured that KemiCond® is fully compatible
with all types of dewatering equipment.
The
KemiCond® standard unit is supplied in a 40-foot container –
or alternatively as a skid-mounted unit – containing a
control cabinet, reactors, dosing pumps, etc. The KemiCond®
standard unit is available in capacities up to 12000 ton DS
per year. For higher capacities plant specific designs can
be made.
When
the KemiCond® solution is up-and-running an optimization
program and performance follow-up is done on a regular
basis. The sludge is hygienized and the volume reduced with
the KemiCond® solution. Increased dry substance (DS) reduces
volume and cuts transportation and disposal costs.

Grove, IL -- Following the success of their earlier
model, Sirius Automation Inc., is pleased to announce
the immediate availability of their improved
‘GraviMatic-II®’ Series of Benchtop Laboratory Robots
tailored for applications within Wastewater/Water
Reclamation Testing Laboratories that involve
gravimetric assays.
Perfect for repetitive,
routine operations in every high throughput Laboratory,
these units are available with 3, 4 & 5 place Analytical
Balances as required. Each installation includes a
self-calibration/test routine to ensure operational
qualification.
Configured for easy-setup,
day to day use-ability and walkaway reliability, these
fast and efficient robots utilize proprietary ‘furnace
friendly’ racks & grippers that are available for a
range of standard crucibles, and incorporation of custom
labware for special cases is also available.
Offered both with and without
full enclosures and humidity control devices, these
fully automated workstations pay for themselves quickly
in headcount savings alone, the improved data quality
and confirmed sampling handling aspects are additional
justifiers! The multi-method software is ‘tiered access
adapted’ and suited for several users, providing simple
‘start run’ access to low level users, but entire
protocol visibility to laboratory management.
The ‘Gravimatic-II®’ Series
is improved over earlier versions in both speed
(throughput) and on-station capacity (number of
samples), plus includes either XP-Pro or VISTA based
Robot Control and Data Handling Desktop PC. Data can be

using the built-in DataBase features.
Sirius Automation Inc. is a
fast growing tailored Laboratory Automation manufacturer
located in greater Chicago with clients in the Chemical,
Pharmaceutical, BioTech and Water Quality markets.

Mr. Losey wants to know DAF
temperatures:
Does anyone know any numbers
on the efficiency of a DAF at different temperatures?
We have wastewater coming in
at temperatures around 160 degrees F at times and I would
like to find a way to justify lowering this temperature.

Does a high pH (= 9) cause

basically? I remember a posting on scum forming as a result
of high pH.

Tembec's
facility in Temiscaming, Quebec. Wastewater from pulp
production is treated in two BioPaq IC reactors where COD is
converted into 50.000 m3/d of methane gas, before being
treated in the activated sludge plant. The methane gas is
desulpurized in a ThioPaq scrubber and used for pulp drying.
