1Health & Safety precautions
This manual contains basic information on the installation, operation and maintenance of the
Tricel Puraflo wastewater treatment system. For this reason, it is essential that these
instructions are carefully read and understood before installation or commissioning by both
the installation crew as well as those responsible for the operation and maintenance of the
system.
This manual shouldbereadilyavailableatthelocationofthesystem.Itistheresponsibility of the
homeowner to ensure that the wastewater treatment system is operated and maintained
correctly and in a safe manner at all times.As safety and security are of vital importance, the
following aspects are critical:
1.1 General
•
Ensure that all the information contained in this manual is adhered to at all times.
•
Treated wastewater is not suitable for human consumption
. It is unhealthy for humans,
pets, and wildlife to drink or come in contact with surface or ground water contaminated
with sewage.
•
It is importantthatlocksarefitted to the lid to preventaccidentalaccess.
•
Neverentera tank,unless qualifiedtodoso.
•
Nakedflamesshall not be usedinthevicinityof thetank due tothe danger of combustion.
•
The manhole covers shall never be left off an unattended tank. Always lock the covers
of the plant when work is completed.
•
Sewage and sewage effluent can carry micro-organisms and gases harmful to human
health.
•
Any person carrying out work on the
wastewater treatment system
must be
appropriately trained.
•
Suitable protective clothing; including waterproof/abrasion-resistantgloves,
overalls,
safetyfootwear, eye,earandrespiratoryprotection, goggles (facevisorsare particularly
effective against splashes) should be worn at all times. All protective clothing must be
ingood condition and be fit for its intended purpose.
•
Always remove contaminated clothing and protective equipment after working with
wastewater treatment plants.Wash hands and face priorto eating,drinkingorsmoking.
•
Wastewater treatment plants contain very low levels of oxygen. Hydrogen sulphide,
methane, carbon dioxide and other
life-threatening gases are also present. Tanks
have manholes covers to provide access to the tank only in times of cleaning and
inspecting the tank from outside.The manhole covers must always be in place and
secure.
•
Keep vehicles and other heavy equipment away from the wastewater treatment plant
and percolation area.
•
Erect a safety barrier around open manholes to prevent anyone from accidently falling
down the manholes.
•
Keepchildrenawayfromthesepticsystemwhenitisbeing workedon.
•
Do not smoke near wastewater treatment plants. Combustible gases could be present
andcausean explosion.
•
Contact a plumber or other qualified person if you smell 'sewer gases'. They can identify
the source and correctitimmediately.
•
The sewage treatment process uses many beneficial microorganisms, like bacteria, in
the treatment process.
However, the plant also contains harmful bacteria, viruses and
disease-organisms.
Liquid and solid contents of the septic system are capable of causing
infectious diseases.

1.2
Electrical/maintenance
•All electrical work to be carried out by competent persons using suitable materials for the
application.
•Do not open the Tricel Puraflo alarm cover without firstly isolating the mains power.
All
power isolation switches should be turned off [Follow Lock-out/Tag-Out Procedure]
before any maintenance/inspection work is done at the wastewater treatment plant.
•Never use electrical lights, appliances or power tools in or close to water or wet ground
near the septic tank or percolation area. This can result in electrical shock or explosion.
•Electrical work must be carried out strictly to the manufacturer’s instructions and to the
relevant national rules for electrical installations.
All connections to the control panel
should only be made by competent qualified personnel. If a cable is damaged, it should
be replaced immediately to prevent electrical shock or damage to the electrical
equipment. All electrical connections are completed on site.
•When working with machinery/electrical equipment, proximity of water shall be noted.
Electrical equipment shall not be wet when working with it.
•
There is potentialdanger when de-sludgingand thereforethis shall neverbe done alone.
•
A wastewater treatment system that fails to fully treat sewage due to poor
maintenance or overloading may allow excess nutrients (phosphorus and nitrogen) to
reach nearby lakes and streams, promoting algae and plant growth. Algal blooms and
abundant weeds may make lakes unpleasant for swimming, boating, and other water-
based activities. This plant growth can also affect water quality for fish and wildlife
habitat. As plants die and settle to the bottom, they are brokendownbybacteriathat use
upoxygen that fish needtosurvive.
•
It is the responsibility of the owner to ensure that the wastewater treatment plant is
operatedand maintained correctly at all times.
•
It is advised that the owner enters into a yearly Service Agreement to ensure the correct
operationoftheirwastewatertreatmentplant.
1.3 Installation:
•
Excavationwork should be plannedwithdueregard tohealth andsafetyrequirements.
•
Septic tank should also be properly vented in accordance with the tank
manufacturer’s guidelines.

Installation
Important
Prior to the installation of the Tricel Puraflo system, it is important to carefully read these
installation instructions.
2.1 Inspection on reception of Tricel Puraflo modules
•
Tricel Puraflo modules should be visually inspected for damage which may have
occurred during transport prior to installation. Any damage should be notified to
the delivery driver and/or to your supplier. Do not attempt to carry out any
unauthorisedrepairs,as thiswillinvalidatethewarrantyon the modules.
•
Oncethe modules have beeninstalled,wecannotacceptanyclaimsfordamage.
2.2 Positioning and precautions
•Only suitably qualified personnel should perform the installation of the Tricel
Puraflo system.
•The groundwater level on the site must never rise above the base of the Tricel Puraflo
modules.
•
Suitably sized equipment will be required to excavate the hole and to lift the
Tricel
Puraflo system
into place (minimum: 6-ton machine).
•The Tricel Puraflo system should not be installed in an area subject to flooding or excessive
water runoff as no flood waters should enter the tank.
•
When selecting the location of the Tricel Puraflo system, ensure that it is always accessible
for future maintenance.
•A septic tank must be installed (or de-sludged if a retrofit installation) and empty, but not
in use, during the installation of the Tricel Puraflo system. Tricel offer septic tanks with an
effluent filter fitted if required.
•The location for each element of the system must be known and marked out prior to
installation.
•In the case of tertiary treatment systems that discharge to a gravel base, the discharge area
must be installed before the Tricel Puraflo system is installed. Tricel is not responsible for
the design and installation of the discharge area.

Modules 7
Excavate a hole that will allow for
a minimum 275mm gravel base
beneath the Puraflo modules
(taking note of water table and
other site conditions). Puraflo
modules can be installed above
ground or so that the lids are level
with the ground level but the lids
must never be covered.
The gravel base must extend
minimum 500mm beyond the
footprint of the Puraflo modules
on all sides.
Excavate a hole that will allow for a
minimum 300m gravel base beneath the
Puraflo modules (taking note of water
table and other site conditions). Puraflo
modules can be installed above ground or
so that the lids are level with the ground
level but the lids must never be covered.
The size of the area covered by the gravel
base is determined by the following
formula:
Area = PE * T * 0.125 (EPA CoP)
7
8
Lay a gravel base (10-20mm pea
gravel) to a height of 200mm.
Ensure the gravel base is level.
Lay a gravel base (10-20mm pea gravel) to
a height of 225mm. Ensure the gravel base
is level.
9
Place the lentils on the gravel base perpendicular to the length of the modules.
The 100mm side of the lentils must lie flat on the gravel base. Ensure that each
lentil is level.
The lentils must be spaced far enough apart that each module is supported at
the locations outlined in the following image:
10
Continue filling the excavation with gravel (10-20mm pea gravel) until the
height of the gravel is level with the top of the lentils. The gravel must be
levelled.
11
A trench, for the rising main, must be dug from the pump chamber/water
treatment plant to the Puraflo modules inlet assembly. We recommend a
300mm wide trench with a 650mm depth. The rising main must be surrounded
by 150mm of gravel all around. The rising main pipe should be 500mm below
ground level to prevent freezing. Backfill the rest of the trench with existing
soil.
12
Using the glue provided, the 32mm PVC outlet pipes must be attached to all
modules before they are placed alongside each other as the pipework that feeds
into the sample chamber(s) will be inaccessible when the modules are in place.
13
Using the lifting ropes, lift the Puraflo modules into position, according to the
layouts in Section 3.3, taking note of the left and right-hand alignments marked
on the modules. Position the modules until they are just touching and they form
a V where they meet at the outlet.
8
14
The lifting ropes should be pulled down below the modules for better
aesthetics.
15
Create a hole 225mm deep in the gravel base where the sampling chamber will
be located. Install the sampling chamber(s) so that the ledge fits under the Tricel
Puraflo modules and into the 'V' shape between the modules.
16
Install the remaining outer PVC pipes and connect them into sampling chamber.
Once the pipework has been connected, build up the level of the pea-gravel
directly beneath the pipework to provide support during the backfilling around
the modules. This will prevent damage or sagging to the pipework which could
result in blockages or leaks.
9
17
Using the yellow inlet pipe assembly provided, connect the inlet pipework to
each module. The rising main coming from the pump chamber/water treatment
system should be connected to this inlet assembly in single zone systems (The
rising main must be connected to the inlet of the indexing valve in multi-zone
systems). The following images show the completed inlet assemblies of the 2,
3 & 4 module systems:
Tricel Puraflo 2-module inlet assembly
Tricel Puraflo 3-module inlet assembly
Tricel Puraflo 4-module inlet assembly
10
18
Once the rising main has been connected to the Puraflo modules, backfilling
around the modules can be completed.
Note:
•
The Tricel Puraflo modules must not be covered with soil.
•
It is important that the outlet pipework is protected from sunlight and
frost damage by ensuring that around the Tricel Puraflo modules is
backfilled with suitable material.
2.3.2 Septic tank effluent filter installation (secondary treatment only)
•Secondary treatment Tricel Puraflo systems require an effluent filter be installed at the
outlet of the septic tank.
oOn sites in which complete secondary treatment systems i.e. septic tank AND Tricel
Puraflo modules, are being installed, the effluent filter must be installed in the
septic tank on site by the installer unless the septic tank has been supplied with the
effluent filter pre-installed, see section 5.3.2.1.
oOn sites in which a Tricel Puraflo system will be installed with a pre-existing septic
tank, an effluent filter must be installed at the outlet of the septic tank, if not
already present.

2.4 Tricel Puraflo systems: 12 - 50 PE
•Tricel Puraflo systems designed for 12-50PE consist of multiple zones, which in turn consist
of two, three or four modules per zone.
•Wastewater is pumped to each zone intermittently via an indexing valve, which is
positioned between the pump chamber and the Puraflo modules.
2.4.1 Indexing valve
•There are two types of indexing valve. The indexing valve supplied is determined by the
number of zones in the Tricel Puraflo system.
o6-outlet indexing valve: Used in systems of 5 - 6 zones
o4-outlet indexing value: Used in systems of 2 - 4 zones
