Winschel Environmental is pleased to announce the addition of Thermal Process Systems ThermAer ATAD Bio-Solids
Reduction System
to its list of products. The ThermAer ATAD (Autothermal Thermophilic Aerobic Digestion) system is a
second generation class A Biosolids ATAD system which provides a means to reduce biosolids production and overcomes the
obstacles experienced with the first generation ATAD technology. ThermAer has proven this second generation technology in
roughly a dozen plants in the US in sizes up to 27 MGD. The system uses an ORP method of control that delivers the precise
amount of oxygen needed by the system at all times.

We believe that the benefits of this system for Virginia will be the ability to utilize existing tankage at higher loading rates. The
system guarantees high amounts of volatiles destruction and the advanced biofilter offgas is odorless. Foaming has been
eliminated with the second generation systems along with providing a high degree of dewaterability. With the increased solids
production from advanced treatment methods being mandated within the Chesapeake Bay watershed, the importance of being
able to keep solids production under control and have the ability to provide alternative handling that a Class A biosolids
provides is of the utmost importance. Above roughly the 3 MGD range the ATAD system can be proven to be the most cost
effective method for sludge stabilization available.

Please let us have an opportunity to meet with you to discuss how this system can benefit you treatment facilities.

July 2007

The Town of Stanley Virginia commissioned their new Dewatering system which features a Prime Solution Rotary Fan Press for
Dewatering of the Town's Biosolids and a Shaftless Screw Conveyor manufactured by Keystone Conveyor. The system
replaces the drying beds previously used by the facility. This system is unique in that it handles a large volume of an industrial
glue waste from a local door manufacturing facility. Winschel Environmental provided extensive polymer testing services onsite
to find a combination of polymers that would be able to precipitate the solids and minimize the effect of the glue rezin in the
filtrate that goes back to the head of the treatment faility. The facility was designed by PHRA and the Biolocal treatment system
is an two stage oxidation ditch. Before and after pictures are below:


View of the original drying beds. The Town spent considerable
time, effort and money on an annual basis to line these with sand,
fill and remove sludge, and then pay for the same sand disposal
with the sludge. Winter handling of the beds was near impossible.
After the upgrade - View of the new solids handling system, Prime
Solution rotary press and Keystone conveyor. (click on the photo
to see a larger view). The town can now achieve its solids
handling in a few days a month, mostly unattended, with no mess.
Their solids are typically greater than 20% and they have
eliminated a difficult and time consuming process at their facility.
A new USEMCO Pump Station with EBARA grinder pumps was
commissioned along with the new rest area facilities for the Fairfield
Area Rest Station on I-81. The system features the USEMCO
Pump-Mate Valve Vault over Wet well design. It is completely
preassembled and tested when it arrives on site. All that is required is
that the contractor hook up the piping into and out of the system and
connect the electrical system. The system is provided as a single point
source of supply to insure system compatibility. VDOT personnel
commented that this was the smoothest startup that they had ever
experienced and are very pleased with the operation of the system.
The Town of Kilmarnock, which is a small community nestled near the Chesapeake Bay,
recently completed construction of their new solids Handling Facility at their wastewater
treatment plant. As part of their upgrade they selected to use Winschel Environmental to
provide a Prime Solution Press (in stainless steel) along with a new screw conveyor from
Keystone Conveyor, and a snap cap digester aeration system provided by Stamford Scientific
(SSI). Their solids handling system previously employed a false bottom drying bed facility
which was converted for use at this facility. The WWTP had to upgrade its biological process
to handle nutrient removal. It is a Schrieber Process which has been modified for the addition
of chemicals for Phosphorous removal.
Winschel Environmental received approval for construction of a USEMCO Elite Package Pump Station with two 60 HP Ebara
Submersible pumps for the Piney River Pump Station in Nelson County. The Elite station is a partially buried station complete
with a generator delivered to the site complete and ready for installation. The contractor need only to prepare the wetwell and
pad to support the facility and then connect the utilities. Please follow our link to USEMCO to see the full line of products to
meet your water and wastewater pumping needs!!!

The Town of Front Royal Wastewater Treatment Facility in Northern Virginia has recently
completed the first phase of permanent solids handling upgrades. They selected a Prime
Solution Press for their facility in 2006 because of the simplicity of operations and
maintenance and superior dewatered product it produces. They replaced an existing Belt Filter
Press with a temporary installation of a smaller Prime Solution Press in 2006 and have installed
the first of two larger presses. The equipment treats aerobically digested waste activated
sludge and consistently produces solids between 22 and 29%.
October 2007
Winschel Environmental was awarded contracts for a USEMCO modular water booster station and a Keystone Conveyor
Cleated Belt Conveyor for the North River WWTP in Harrisonburg, Virginia. The booster station will be provided in two
segments, an R-30 insulated building with aggregate panel exterior and a shingled truss roof for placement on top of the
booster system. The system consists of two 25 HP booster pumps. The system is delivered on site complete and pretested at
the manufacturers' facility requiring only site preparation and utility hookup by the contractor.
June 2008
Town of Kilmarnock - selected Winschel Environmental to provide sound dampening blower
enclosures for their three new PD blowers at the facility. The Town was recieving complaints
about the amount of noise generated by the new blowers that the town installed. Winschel
Environmental, LLC provided a complete turnkey package including onsite engineering to
custom design and install a high quality aluminum enclosure for the blowers. The neighbors
are sleeping soundly again!
September 2008
Henrico County- Commissioned the new solids conveyance system at the water reclamation
facility provided by Keystone Conveyor. The conveyor consists of 240' of new 24" wide
troughing belt conveyor with electrically actuated plows for complete control of the
delivery of plant biosolids. The system ties into the plant PLC for automated operation of
biosolids conveyance from the facility Centrifuges. The new system will eliminate the
constant shuttling of solids via front end loaders between bays, saving the County
considerable money on labor and machinery.
October 2008
Strawberry Hill Pump Station - Henrico County Commissioned the new headworks screening
conveyance system and new overflow equalization basin mixers at the Strawberry Hill Pump
Station. The Conveyors were provided by Keystone Conveyor. The conveyor consists two
sections of new 18" wide troughing belt conveyor for removal of screenings from the pump
station. The new system eliminates the manual handling of solids hoppers and automates
discharge into dumpsters located outside of the building.

The Mixers were provided by Dominion and Aquaturbo. The Screwpellor Mixers are
designed to keep solids in suspension to minimize maintenance and cleaning after the basins
have been used.
November 2008
Town Of Dublin Virginia -The Town of Dublin replaced the pumps in their two municipal pump stations and upgraded the stations
with EBARA DVFU series Solids handling vortex impeller pumps. The competitors grinder pumps were ragging up and clogging
regularly requiring the town to regularly (and at the worst possible times) to come out with a boom truck to remove the pumps and
clean them to keep the pump stations in service. After meeting with Town Officials we recommended switching to Ebara pumps with
vortex impellers because of their ability to pass solids without ragging up in the lower units.
January 2009
Town Of Mt. Jackson, Virginia - The Town of Mt. Jackson finished the installation
of the solids handling equipment and commissioned it in the final location.
Winschel Environmental provided the equipment originally in 2007. The town used
the equipment as a mobile dewatering system during the construction of the new
wastewater facility. Winschel Environmental provided a process dewatering
package including a Prime Solution Rotary Fan Press, Two 3" Periflo RBT 70
peristaltic hose pumps (to handle extremely high suction lift conditions) and a belt
conveyor by Keystone Conveyor.

The equipment is dewatering a secondary waste activated sludge type system with
typical solids production > 20%. The equipment was provided on separate skids to
facilitate interim usage and simplicity of final install. The control systems were all
integrated for the equipment through Winschel Environmental. Prior to the facility
upgrade the Town had solids handling issues with their old drying beds and opted
to upgrade to mechanical dewatering. The Town selected the Prime Solution Rotary
Press after onsite pilot testing and equipment rental of the Prime Solution Press for
a digester cleaning. The Town personnel now simply turn on the units in the
morning and go about their day, checking in at intervals to make an minor
adjustments that may be needed.
August 2008
Town of Vienna - selected awarded a contact to USEMCO to provide package water booster stations for the Town. The town
currently has a tank that sits below the HGL used in the system and the new pump stations will be used to cycle water out of the
tanks into the system to provide adequate recirculation of water from the tanks.
July 2008
City of Manassas Park - Awarded a contact to USEMCO to provide package water booster
stations for the City's Joshua Court Pump Station. The town is using a USEMCO Aqua Pak
Package water booster station. The station is a four pump system with a peak capacity of
four million gallons a day. It is being provided with exterior brick and a peaked roof. The
station once complete will only need to be set onto the foundation and have the utilities
connected once on site. The picture to the left contains the drawing of the facility.
Town of Middletown, Virginia - Middletown commissioned the new WWTP which replaced
its lagoon treatment facilities. Winschel and Dominion provided headworks Screenings by
WTP Equipment Corporation, the Biowheel WWTP manufactured by Wastewater
Technology, Inc
., , the Solids dewatering system by Prime Solution Inc. , and conveyors by
Keystone Conveyor
. The facility is rated for MGD.
