1.0 Introduction
All Advanced Water Recycling Systems offered by United Surface Solutions use a chemical process to
remove unwanted contamination from your water so it may be safely recycled. This is different from
purely physical pre-treatments such as clarifiers or osmosis-type systems because we are actually
affecting a chemical change that transforms heavy metals and other toxic substances back into safe
solids, much as they normally occur in nature. Wastewater is comprised of a wide variety of
substances in many different states. Most of these can be determined by looking at the source of the
water. If you are in a deburring shop that is finishing products made of chrome, zinc, and nickel, then
you will have those metals in your wastewater.
United’s units typically use a floc and drop system. A flocculent agent clumps together the solids
floating in the process tank and drops it to the bottoms of the tank for easy removal.
1.1 Method
A dry agent “GR-20” is automatically metered into the processing tank for a simple, and single,
automated process. This is the recommended method of wastewater recycling.
Wastewater treatment with GR-20 takes only minutes, yet several complex chemical reactions occur.
First, the acidic component of the GR-20 causes oily contaminants to coalesce and separate from the
wastewater. Next, the polymeric cationic portion of the formulation attracts any remaining oils and
larger, more highly charged anions. Finally, the basic component activates, precipitating metallic
hydroxides and driving the system to a fully flocculated condition where the cationic polymer
molecules (with any adsorbed oil), metallic ions, and positively charged contaminants are attracted to
the GR-20’s clay particles. Heavy metal cations remaining in solution will exchange with the sodium
on the clay and will bond to the clay platelets by electrostatic forces. The fully reacted mass is a
complex mixture of encapsulated contaminants and waste solids held together by Van der Waals
(weak), as well as electrostatic (strong) forces. The clay particles agglomerate, entrapping and
surrounding suspended solids completely. Pozzolanic reactions also occur, forming cementitious
particles which settle to the bottom of the vessel. The entire microencapsulation process is completed
in just minutes, leaving clear and in most cases sewerable, water.

3.0 Setup
Overview:
The TC250 is a stand-alone closed loop parts rinsing station. Once filled with fresh water it will recycle
the water many times by utilizing a polymer reactant to remove any suspended solids and cleanse the
water. It is not intended to remove all surfactants, oils or to purify the water. The system consists of a
clean water holding tank, pressurized well pump, sink basin with faucet and process tank. When the
spray handle is pressed the water is pumped from the clean water tank to the faucet via the pressure
pump. The water rinses the parts, passes through the sink basin to a gray water sump and then is
pumped into the process tank. The process tank fills and starts the cleaning process. The water is
mixed while a granular reactant is added. This creates a floc gathering suspended solids and cleansing
the water. Microbubbles are added to the floc to causing it to float. After mixing, a rest period is
needed to allow the floc to float to the top and separate from the clean water. The Clean water drains
through a filter media and is pumped back into the clean water tank. The filter media then traps the
floc and allows the sludge to dewater in the sludge tray. Once completely dewatered the floc, now
sludge, can be disposed of. The unit can also be plumbed to include a finishing system in a closed
loop type of configuration.
Start Up:
1. Remove all packing material, panel protectors. Cut ties on float switches and hang inside tanks
2. Connect power to 240VAC/60Hz, 1ph, 20-amp source
3. Plumb closed loop system according to P&ID
4. Press the Blue Fill button to fill the clean water tank
5. Test run with clean water to prime all pumps and check for leaks
6. Install filter paper in the tray
7. Insert the Intake hose into the box or bucket of GR
Operation:
1. As you use the Sink the TC250 will automatically fill up the Left/Process tank, when it is full the
Red light will come on - this indicates you need to start the process. NOTE: There is a small
reserve of clean water to continue rinsing parts while processing. The clean water pump will
shut off and RED light will activate when the reserve is depleted. NOTE: Flashing Green light
plus RED steady light indicates system processing & reservoir depleted.
2. Press the Start button to begin the process, the Tower Light will turn Flashing Green.
3. Once the batch is complete (approximately 20 mins) the Tower Light will turn Steady Green.
Check that the filter paper is placed properly in the sludge tray.

4. Start draining the tank by opening the Drain Valve approximately 30% allowing the clean water
to drain through the filter paper. After the water is drained and gray sludge start to appear on
the filter paper turn the valve to 100% open until all sludge is drained.
5. When drain is complete turn valve to its closed position and press the Reset button to turn off
the Green Light and reset the system. The Sink is now available for rinsing. NOTE: After the
system is Reset the Start button can be pressed at any time, the process will automatically start
when the process tank becomes full. Green light will Flash to show that the system is active.
Maintenance:
1. Once a week process and drain all clean water from system and replace with fresh water.
2. Flush Process Tank with clean water to remove all sludge and debris.
3. Clean UV Light daily using scraper rod on UV tank.

4.0 Operation
Processing wastewater with the TC250 is easy and requires very little operator time. Processing a
batch of wastewater is done automatically, except for the quality check and the manual draining
sequence.
4.1 Operation –With Sink
After pouring wastewater into the sink, wastewater pumps into the wastewater holding tank, then into
the process tank. When the process tank reaches capacity, the system alerts the operator that the
process is ready to begin by illuminating its notification beacon. The operator must now press the Start
button to begin the process The system will begin circulating the wastewater while pumping in the
required compounds and adjusting the air and pump flow to separate all suspended and dissolved
solids from the water (this process takes 15-20 minutes).
The system will notify the operator once the process is complete. At this point, it is time to drain the
process tank.
1. Ensure filter paper is in place in the sludge tray.
2. Open the valve underneath the process tank to the half-way point.
3. Slightly dirty water may flow before clean water.
4. After clean water finishes flowing, sludge begins to flow.
5. Fully open the valve and allow the tank to empty into the sludge tray.
6. Open sprinkler valve in process tank to rinse excess dirt.
7. Close all valves.
8. Press Reset on the control panel. Once the sludge has dewatered enough, fold the filter paper
and dispose of the waste.
4.2 Operation –Without Sink
1. Pump wastewater into the left bottom holding tank.
a. Ensure wastewater being pumped in does not exceed 30 GPM (gallons per minute).
2. When the process tank fills, the alert beacon will illuminate like usual. Start the process as
described in “With Sink” operation.
