INTRODUCTION
The Clearstream System is one of the finest aerobic wastewater systems available today.
Our system converts the sewage from your residence or business into a clear, odorless liquid. This
high degree of treatment is accomplished at aremarkable low operating cost per month. The
system has been simplified over the years to make it as inexpensive to operate and as low in
long term maintenance as possible. Homeowners who have lived with the nuisance of a septic odor
lingering in their neighborhood will truly appreciate the pleasure of owning aClearstream System.
Clearstream Model DA Systems
comply with NSF Standards 40 for Class Iresidential wastewater
treatment systems, 245 for total nitrogen reduction and 350 for onsite residential and commercial
water reuse treatment.
PROCESS DESCRIPTION
There are four basic zones or compartments to this treatment unit. Wastewater enters the
aeration chamber of the process tank, where it is mixed with organisms formed during decomposition
of organic material in the wastewater, mixing in the chamber is achieved by release of compressed air
near the bottom of the chamber through fine bubble diffusion.
Aconical shaped clarifier is located internal to the process tank toprovide for separation ofthe
solids from the mixed liquor. The mixed liquor passesinto the bottom of the clarifier by hydraulic
displacement aswastewaterenterstheaerationchamber.Solidssettledfrom the wastewaterare drawn
back into the aeration chamber from the bottom of the cone by the hydraulic roll created by the air
released in the aeration chamber and are dispersed by the mixing induced by the aerator. An airlift
assembly controlled by atimer and solenoid switch borrow air from the aerator to divert a
small continuous return of water from the clarifier back to the pretreatment tank.
Approximately 7 hours of return is needed for treatment system max flow to provide denitrification. Discharge of
the final clarified effluent occurs through a submerged tee assembly located below the clarifier
surface to prevent discharge of solids that may float on the surface of the clarifier.
When disinfection is required before final discharge, a pp r o p r i a t e disinfection options are
available. If used in Std. 350 operation the Clearstream Model CS120UV unit must be installed on
discharge.
When properly loaded and maintained, the aforementioned process allows the Clearstream
Wastewater Treatment System to provide years of satisfactory service for the consumer. Clearstream
Model DA systems meet the performance requirements of NSF Standards 40, 245 and 350. Actual
GCT test results used to determine Clearstream's certifications met Standard 245averaged <10
mg/l BOD,<10 mg/l TSS and >50% total nitrogen reduction .

OPERATING MANUAL
In the event you experience a problem with your Clearstream Aerobic Wastewater Treatment
System or if service is required, you may reference the ClearstreamControl PanelCover for the name,
address and phone number of a local service person that can provide service for your Clearstream
Unit. After the expiration of your initial two year service policy provided by the system installer, you
may obtain a continuing service policy on a yearly basis which will include terms comparable to the
initial service policy from a local service person that is trained and certified by Clearstream.
In order for the Clearstream System to function at optimum performance levels, the system will
require periodic service. The normally expected service that is associated with the system includes:
1. Repair or replace aerator
2. Clean filters onaerator
3. Break up scum in clarifier
4. Pumpsludge from aeration tank
5. Pumpsludge from pretreatment tank
6. Check aeration diffusers
7. Check surge control weir
8. Check denite effluent return flow
9. Replace UV bulb (when UV is installed)

* Any sludge removed from pretreatment tank or Clearstream Unit must be disposed of according to all state, local and federal
regulatory requirements.
To remove solids from pretreatment tank drop pump hose through access opening on top of tank
all the way through to the bottom of the tank. Pump out the whole tank volume, then fill the tank back
up immediately.To remove solids from aeration chamber,drop hose through access opening in tank
all the way to the bottom of the tank. Pump only 1/2 of the total tank volume and fill tank back up with
water immediately .
Todetermine if all system components are functioning properly,look and/or listen to see if the
visual/audio alarm system is illuminated or making abuzzing sound. If the alarm is activated, then
either the aerator has lost air pressure or the high level float inside the clarifier is indicating a high
water level condition. Verification of either condition can be made by checking air pressure from
aerator with a pressure gauge and opening the access opening to the treatment unit to see if the
water level inside the clarifier is at alarm level. After inspection of the clarifier, be sure to
securely fasten the access cover back in place and tighten the tamper resistant screws firmly.
To determine if the system has the desirable “mixed liquor” and effluent characteristics, first
remove the access cover. Monitor for odors coming from the tank. If the odor is a sweet or a musty
smell, the system is operating in a desirable aerobic condition. If the odor is foul or smells like a
rotten egg, then the system is operating in an undesirable anaerobic condition. Visually monitor the
“mixed liquor” for color. If the color is a brownish color, then it is operating in a desirable aerobic
condition. If it is grey or black in color, it is operating in an undesirable anaerobic condition. The
system effluent should be clear with very few noticeable light brown solids suspended in the
effluent. The effluent should not be dark or turbid in color or clear with great numbers of light
brown suspended solids noticeable. After inspection of the system’s interior, be sure to securely
fasten theaccess cover back in place andtighten the tamper resistant screws firmly.
In the event the alarm panel light and buzzer is activated, call your local servicing dealer
whose name, address, and phone number should be affixed to the face of the panel.

To collect effluent samples from a system, a sample port must be added downstream of the effluent
discharge. The sample port should be installed so that effluent cannot remain below the discharge
water line and build up solids. A sample bottle should be capable of being lowered into the port on a
string and laid on its side in the direct flow line of the discharge and removed when full of effluent.
The expected effluent from the system should be less than 25 mg/l CBOD and less than 30 mg/l
TSSwith a PH range of 6-9 and total nitrogen removal of a minimum of 50%.
For the first two (2) years from the date of installation, your local servicing dealer (from whom
you purchased your Clearstream System) will make periodic inspections of your system to make
sure it is functioning properly. The dealer will perform necessary maintenance to the system at no
charge unless the required maintenance is not warranty related. Pumping of the system is not
included. After the first two (2) years, the dealer will offer a continuing service policy for a nominal
annual fee. The two (2) year service policy (two service calls per year) and the continuing service
policy are minimum requirements of NSF Standards 40 Class I, 245 and 350 certified wastewater
treatment systems. If local service requirements are greater than those of these NSFStandards or if
the local regulations require others to perform the service on these units, Clearstream’s limited
warranty will still be honored.
For the Clearstream Aerobic WastewaterTreatment Unit to function properly it must be used for
the treatment of domestic wastewater from residences or other waste flows with similar loading
characteristics. Typical domestic wastewater consists of the flow from toilets, lavatories, sinks,
bathtubs/showers and washing machines. To prevent malfunctions of your Clearstream Unit, the
following guidelines should be followed:
1. Any sewage system, whether aerobic or septic, should not have inorganic materials
(plastics, cigarette butts, throwaway diapers, feminine napkins, condoms, etc.) that the bacteria
cannot consume, discharged into the system.
2. Large amounts of harsh chemicals, oil, grease, high sudsing detergents, discharge from
water softeners, disinfectants or any other chemical or substance that kills bacteria should not be
discharged into the system.
3. Excessive use of water, over the design flow of the system, or organic overloading in
excess of design parameters will cause the system not to perform to its fullest
capabilities.
4. The proper operation of this or any other sewage treatment system depends upon the
proper organic loading and the life of the micro-organisms inside the system. Clearstream is not
responsible for the in-field operation of a system, other than the mechanical and structural
workings of the system itself. Field abuse and overloading of the system can only be cured by the
user of the system.
5. When wastewater discharge, into a Clearstream Unit, is seasonal or intermittent to a point that
the owner wishes to turn off the electricity (for more than three (3) months) to the aerator, no
special service is required.

CLEARSTREAM INSTALLATION INSTRUCTIONS
Before installation of the Clearstream Treatment Tank, first install a pretreatment tank
(septic tank) with a volume of not less than 50% of the gallon per day rating of the
Clearstream Unit. Pretreatment tanks shall comply with minimum sizing specifications
outlined in the Clearstream specifications section.
UNLOADING/PACKING INSTRUCTIONS:
1. All compressors are packaged to prevent damage during shipping and handling.
2. Please be careful during shipping or handling of the linear compressors they are
fragile and can be damaged if dropped from only a short distance. If dropped hard
enough the cast aluminum housing may be damaged and render the compressor
useless.
3. The most common issue resulting from a linear compressor being handled inappropriately is the
safety switch being tripped. Please refer to the repair manual for switch reset instructions if the
compressor fails to power up.
4. All control panels are packaged to prevent damage during shipping and handling.
5. Clearstream electrical control panels are fragile and should be handled as such during
shipping and handling. All electrical control panels have circuit breakers, lights and
electrical connections and many have relays and timers that are all fragile. Components
may be replaced if damaged but if the panel enclosure its self is damaged the panel may
be rendered useless.

CLEARSTREAM TANK INSTALLATION
1. Prepare an excavation having minimum dimensions of at least one (1) foot larger than
the dimensions of the tank. Make sure the depth of the excavation is deep enough to allow
gravity flow to the inlet of the system and that the excavation bottom is level. Never install
the Clearstream tank deeper than a depth that will require more than a maximum of 18
inches of riser depth. The access cover shall always be above final grade after tank
installation. In applications where more than the maximum 18 inches of riser is required,
install a lift pump upstream of the Clearstream tank to pump the pretreatment tank effluent
to the Clearstream tank at normal grade. In these special applications where a lift pump is
required, contact Clearstream for more details as to pump size, maximum dosages and
maximum flow rates.
2. Set the Clearstream tank in a prepared excavation that has a solid, level bottom that will
eliminate tank settling. The excavation bottom should have no rocks or sharp objects
present.
3. When lowering the concrete tank into the prepared excavation use a spreader bar. Only
spreader bars and other lifting devices, that have been designed and tested for lifting
Clearstream concrete tanks, should be used. Never lift concrete Clearstream tanks unless
they are empty of all liquids.
4. Make sure the inlet 4” Sch. 40 PVC pipe is aligned properly to incoming sewage line.
5. For the Clearstream Unit to function properly, the tank must be level. To properly level
the tank, lay a three (3) foot level across the tank in several directions. Shift the tank in the
hole, as necessary, to make the tank level in all directions. The tank may be slightly out of
level, but it should not be out of level enough to cause tank malfunctions.
6. Fill the tank with fresh water, checking periodically to make sure the tank remains level.
7. Connect the 4” Sch. 40 PVC Clearstream inlet pipe to the incoming sewage line. Make
sure the incoming sewage pipe is level with or higher than the inlet pipe to the Clearstream
Unit. The Clearstream Unit should only be connected to a plumbing system from a
wastewater source which has been properly trapped and vented in compliance with State
and Local plumbing codes.
8. Back-fill the excavation in layers with back-fill material that will settle properly around the
tank. Tamp the back-fill material as each layer is placed around the tank. If necessary, use
water to help settle the soil around the tank. Special care should be taken to either tamp
soil under where inlet and outlet pipes are bridging the excavation or use some other method
of supporting pipes across the excavation. Do not back-fill with heavy chunks of clay or large rocks.
9. Before completing the back-fill, be sure the electrical conduit from the tank to the Control Panel and
the air line from the aerator to Clearstream Unit has been laid underground.
6 of 12

10. For below normal grade installations a Clearstream 20-inch diameter riser may be used. In no
case shall more than 18” of maximum riser depth be used on a Clearstream Unit to bring the access
covers above the final grade. All risers must be sealed with a sealant to prevent ground water
intrusion before back-fill is completed.
11. Before leaving excavation site, be sure to securely fasten the Clearstream access covers in
place with the tamper resistant screw(s). Tighten screws firmly to keep unauthorized
personnel from gaining access to the inside of tank.
CLEARSTREAM AERATOR AND CONTROL PANEL
1. Mount the Clearstream Control Panel in a location that can be easily noticed by the occupants.
2. Wire 115 Volt, 60Hz power from an electrical disconnect to Clearstream Control Panel. Wire from
Control Panel to Clearstream Tank electrical junction box through conduit. Use wiring diagram
provided for each version of the Clearstream Control Panel series. All electrical wiring should be
installed by a qualified technician in compliance with NFPA 70 for all electrical components, electrical
connections, and system installation.
3. Install Clearstream Aerator Model CS-103ET6, as close as practical to the tank, but in no case
greater than one hundred (100) feet away. Run 3/4” Sch. 40 PVC air line from aerator connector
to the air line connection at Clearstream tank. Be careful to backfill under-ground air line in
manner which will not cause air line to leak. Aerator must be installed in a location that is dry,
non-dusty and highly ventilated.
COMPLIANCE WITH LAWS
The Clearstream Unit must never be installed without first obtaining all permits and approval
from the local regulatory body. In areas that do not have local control over environmental
activities, all applicable State and Federal environmental codes must be adhered to as
well. Only properly licensed and trained individuals should install Clearstream equipment. The
effluent from the system should only be utilized for disposal as described in NSF/ANSI Standard
40, 245 and 350 and as is in compliance with all local, state and federal requirements. Special
care should be taken when installing a unit to prevent cross connections and protect against back-
flow to potable water supplies.
