2.1 Process Overview
1. Filling
Water is moved from Pretreatment to Reactor.
2. Reaction
A mixture of aeration, pausing, and mixing
breaks down BOD and allows for nitrification
and denitrification within the same tank.
3. Sedimentation
Nothing moves in the Reactor and the
solids settle to the bottom, leaving
clear water at the top.
4. Clear Water Discharge
Clear water is pumped from
the Reactor to the discharge point.
5. Sludge Return
Excess sludge is returned from the Reactor
to the pretreatment to maintain a proper sludge age.
3.0 System Design
3.1 Pretre tment or Septic T nk
The pretreatment tank, riser(s), and lid(s) must be watertight. The minimum volume
shall be 250 gallons per bedroom. Alternatively, the size and configuration shall be in
accordance with State or Local requirements for septic tank sizing.

3.3 Cle r W ter Pump
The clear water pump (discharge pump) is an integral part of the system. This is
advantageous since the SBR is essentially a primary tank, treatment unit, and pump
tank all-in-one. The pump provides timed dosing for a downstream component
such as a polishing filter or drainfield. The standard kit contains a typical 0.5 HP
effluent pump. A larger pump can be included in the kit where required. The clear
water pump can be used to discharge to the following:
Polishing unit such as the Puraflo peat fiber biofilter with optional pad dispersal
ravity trench or bed
Low Pressure Pipe (LPP) drainfield
Drip irrigation

The volumes can vary from the values in the table. Consult with Anua for alternate designs.

3.4 Emergency Stor ge nd Al rm Conditions
PuraSys SBR controls the movement of effluent through the system in a timed
sequence of batches. PuraSys SBR incorporates a clear water discharge pump. Since
treated effluent is timed dosed from the system, adequate emergency storage
must be provided. This is typically provided in the pretreatment tank due to the
operational sequence of the controls. For a one tank, 2-compartment configuration,
the reactor chamber can be included in the emergency storage calculations.
1. ne Tank, 2-Compartment Configuration
The total emergency storage volume is calculated based on the available
volume in the pretreatment tank and the reactor chamber/tank above the
normal operating levels to the inside tank lid. Since the chambers are con-
nected via the air space above the baffle wall, volume in both chambers can
be counted for emergency storage. In some jurisdictions, the riser volume can
be counted for emergency storage. Emergency storage can be calculated as
follows:
Pretreatment tank: Determine the volume between the top siphon hole to
the top of the tank (inside lid).
Reactor chamber: Determine the volume between the high water alarm
and the top of the tank (inside lid).
If allowed per local jurisdiction, determine the volume in the risers.
Total storage volume = Pretreatment + Reactor + Risers

2. Two Tanks Configuration
The total emergency storage volume is calculated based on the available volume in the
pretreatment tank above the normal operating level to the inside tank lid. In some jurisdictions,
the riser volume can be counted for emergency storage. Emergency storage can be calculated
as follows:
Pretreatment tank: Determine the volume between the top siphon hole to the top of
the tank (inside lid).
If allowed per local jurisdiction, determine the volume in the risers.
Total storage volume = Pretreatment + Risers
3. Alarm Conditions
An alarm will trigger under the following conditions:
High water float activated in reactor chamber.
Aerator current <1 or no current.
Siphon/sludge pump current <1 or no current.
The operational sequence is outlined below:
If the clear water discharge pump fails or malfunctions, a high water condition will
occur in the reactor chamber. The high water condition will trigger the an alarm. The
high water alarm will suspend operation of the siphon/sludge pump.
If the current sensor does not read proper current to the aerator, an alarm will trigger.
The aerator alarm will suspend operation of the siphon/sludge pump.
If the current sensor does not read proper current to the siphon/sludge pump, an alarm
will trigger. At this point, this pump is not operational.

Backfill and grade around the reactor tank to prevent infiltration of surface water.
4.4 Site Restor tion
The riser lids must be installed above grade with the ground landscaped to divert storm water
away from the area.
Backfill should be suitable, loose, workable material.
Backfill must be free of debris and large or sharp objects.
Compact backfill sufficiently to adequately prevent settlement.
Landscape (e.g. grass seed, sod, straw, landscape stone, xeriscape, etc.) the sloped backfill area
and any trench excavation
lines with a suitable indigenous seed variety or use other methods.
PROVIDE EROSION PROTECTION AS REQUIRED PER DESI N PLAN.
Installation Warning
If you are not using an air break on
the clear water pump discharge pipe,
then install a check valve!
Construction Warning
During construction, harmful
chemicals such as paint and
solvents can harm the system
microbes if dumped down the
drain. These items should not be
allowed into the treatment plant.

5.0 System Wiring
The cables are coded to match the connections between the
aerator, pumps, and float switches to the junction box and
control panel.
The smart control panel is housed in a NEMA 4X enclosure. The
wiring diagram and instructions are located inside the panel.
Incoming power must be 240V, 1 Phase and 120V, 1 Phase.
5.1 Power Supply
The system must be wired by a person qualified to do electrical
work per the applicable State or Local electrical code.
The control panel requires two separate incoming power
feeds as follows:
20A, 2 Pole, 240V breaker
20A, 1 Pole, 120V breaker
6.0 Re ctor Venting nd Plumbing
6.1 Re ctor Venting
Aerator must be supplied with fresh oxygen.
Direct aerator air tube into vent housing and cut to proper length to insure hose will rest inside
of vent housing without impeding air flow to aerator.
Air vent included in the kit is not required for use. However, air tube must exit to atmosphere in
order to obtain fresh oxygen to inject into aerator
Ensure the aerator is properly secured to the riser with the clip included in the kit.
Recommended
Surge Suppression
In order to add extra protection
to the control panel, the addition
of external surge suppression
is recommended.
The surge suppressor should be
attached in parallel to the
junction on the main power line.
