Delivery and Inspection
The ThickTech™ unit is shipped as a completely assembled unit, ready for installation.
After the unit has been unloaded, conduct a visual inspection and count of the shipping
containers to determine if any shipping damage or material shortage occurred in transit.
Be careful not to jar crates and/or to puncture crated materials with lifting forks.
NOTE: You must report, in writing, any damaged or missing parts to the
shipping carrier and Parkson Corporation within 48 hours of receipt of
the unit. Purchaser shall bear the responsibility for the replacement of
equipment that is determined to be missing after this period.
To assist in identifying correct quantities and parts, reference the attached packing list on
the shipping crate. A purchase order shall accompany any order to Parkson Corporation
for replacement of parts that were damaged during shipment. The purchaser shall direct
all shipment damage back charges to the carrier.
Storage
For storage under 60 days, the equipment should be covered for protection from the
environment and well ventilated to prevent moisture build-up on surfaces. Coverings
should be secured to prevent rubbing on the equipment. The unit drum should be
operated for four (4) revolutions once every two (2) weeks, if power is available, or rotated
manually at least one full revolution. Upon completion of the drum rotation or operation,
the unit should be stopped on a different drum location and trunnion wheel location to
avoid the development of flat spots in trunnion wheels or drum cylinder.
NOTE: Some ThickTech™ units may be shipped with the rotary drum supported on
shipping blocks. In this condition it is not necessary to rotate the drum as
stated above. The shipping blocks must be removed before start-up and first
operation.
Coat all exterior non-painted metal shafts and surfaces with a long lasting rustproof
coating effective outdoors (similar to Cortec products VCI-368 or VCI-389).
Long Term Storage (Additional Requirements)
For long-term storage the gear reducers should be filled to the proper level with the
correct type of oil. Add an oil based corrosion inhibitor equivalent to an oil concentration
of 2 - 4% of the standard oil volume of the unit gear reducers (similar to Cortec product
M-529). Attach a Long Term Storage tag, to the eye bolt of the reducer using plastic tie
wrap, indicating the need to remove the rustproof coating applied to shafts and exposed
surfaces with mineral spirits. It is not necessary to adjust or change the gear oil.
CAUTION
STAINLESS STEEL MATERIAL WILL APPEAR TO RUST IF CONTAMINATED WITH
WELD SPATTER, CARBON STEEL DUST FROM A GRINDING WHEEL, OR OTHER
AIRBORNE OR WATERBORNE CONTAMINANTS. SPECIAL CARE MUST BE
TAKEN TO PROTECT THE UNIT AT ALL TIMES.

SECTION TWO
Hycor®ThickTech™ Unit
TECHNICAL DESCRIPTION
!DANGER !
REVIEW ALL SAFETY PRACTICES LISTED IN SECTION ONE BEFORE
PROCEEDING.
Application
Designed as a rotary drum sludge thickener, the ThickTech™ unit performs two functions.
The first function is to achieve flocculation with minimal amount of expensive chemicals.
The second function, dewatering, takes place along a multi-zone drum cylinder. The zones
can have different size mesh media to augment thickened solids and capture efficiency as
the sludge moves along the length of cylinder.
Unit Description
The ThickTech unit will consist of: flock development tank, driven impeller, step down
header, multiple stage rotary drum with filtration media, drum drive system, supporting
frame, trunnion wheels, horizontal stabilizer wheels, spray deflection covering, spray wash
header, spray wash booster pump and return water collection tank.
(See page 2-1A or 2-1B based on model)
The flock tank, with drive impeller, increases flock development.
The step down header inside the rotary drum receives the influent from the flock tank and
directs it to the screen cylinder for separation. The distribution system distributes the flow
to both sides of the screen surface.
The multi stage rotary drum cylinder separates the solids and transports them to the solids
discharge via a split auger flight arrangement.
The drive system rotates the screen cylinder by utilizing a chain and sprockets.
The frame acts as the main support system for the flock tank and screen cylinder. Parallel
to the cylinder screen axis, the bottom of the frame provides the mounting surface.
The trunnions are rollers that support the screen cylinder on both ends and center. They
allow for cylinder rotation.

The stabilizers wheels limit the horizontal movement of the cylinder and are fitted to the
frame at the center of the rotary drum.
The rotary element is covered on the outside with shower deflection panels designed to
contain any fugitive spray and minimize mist emissions. The panels overlap and are
fastened to the framing members.
A single manually operated self-cleaning washing header is oriented in a horizontal position
the length of the rotary system to maintain positive cleaning with each revolution of the
rotary system, forcing the washed off solids to return to the mass of solids tumbling inside
the rotary element. The spray wash system operates on a continuous basis.
A wash water booster pump is provided and sized according to the specific unit
requirement for pressurized wash water. The pump boosts the required 20 to 40 psig
water to 100 psig for use in the spray header.
All elements of the rotary system and supporting frame are contained and mounted over
the return water or filtrate water collection tank. Delivery of collected filtrate water is
through a gravity drain.
Operation
The sludge mixed with chemicals enters the flock development tank tangentially at the
bottom and completes its flocculation. The flocculated solid and liquid flow from a
tangential outlet into the rotary drum screen through a step-down header. In the rotary
drum screen the liquid separates from the flocculated solids through the woven wire mesh,
is collected in the return water tank and exists through a drain in the bottom. The solids
pass through four (4) dewatering stages before being discharged from the end of the unit.
Mounted above the rotary drum screen is a self-cleaning wash water spray header. This
spray header keeps the rotary drum screen openings clear of solids.
