The ECOmar S Sewage Treatment Plant (STP) is designed to auto-manage the sewage level inside the on board collecting
tank. The standard management system of the level inside the collecting tank is essentially composed by the supplied
Level
Probe
and by the relative
Level Probe Control Box
. When the management system of the level signals from the collecting
tank is correctly installed and connected (refer to the
Management system of the level signals from the collecting tank
sensors
and the
INSTALLATION
sections) to the Main Control Box of the Main Unit; the plant starts up every time the
sewage collecting tank (your supply) is full and continues to run until it is empty.
The sewage to be treated is pumped from the on board collecting tank to the Treatment Tank of the Main Unit by the
Filling
Pump
;
which, if correctly installed (refer to the
INSTALLATION
section), also performs a pre-maceration on the sewage,
while transferring it. An anti-siphon valve set is supplied for the filling pump to prevent siphoning on the filling line.
When the transferred sewage reaches the min level of the Multi-point Ball Level Switch, installed on the Treatment Tank of
the Main Unit, the system Main Control Box
stops the Filling Pump and activates the Disinfectant Liquid (H
2
O
2
) Dosing
System and the ECOFLOC Dosing System at the same time.
If correctly installed and set (refer to the
INSTALLATION
and to the
System Settings
sections) the
Disinfectant Liquid
(H
2
O
2
) Dosing System
injects, throughout the relative injector installed on the Treatment Tank, a pre-set quantity of H
2
O
2
solution inside the tank to disinfect the water to be treated.
During the same time, (refer to the
PCB CONTROL PANEL – Functional Description
section), the
ECOFLOC Dosing
System
, if correctly installed and set (refer to the
INSTALLATION
and to the
System Settings
sections) injects, throughout
the relative injector installed on the Treatment Tank, a pre-set quantity of ECOFLOC solution inside the tank to activate the
sludge separation process.
At this point, the Main Control Box activates the
Sea Water Pump
; which, if correctly installed (refer to the
INSTALLATION
section), pumps a set quantity of clean seawater from the on board seacock valve (your supply), to the Treatment Tank for the
sewage dilution. An anti-siphon valve set is also supplied for the seawater pump to prevent siphoning on the seawater line.
After this preliminary preparation phase, the sewage treatment that takes place almost exclusively on the plant
Main Unit
,
begins.
All chemical-physical reactions necessary for the sewage treatment happens inside the
Treatment Tank
. This tank is
provided with a
Multi-point Ball Level Switch
, which is designed to stop the Filling Pump; when the set quantity of sewage
(refer to
TREATMENT CAPACITY
section) is inside the tank; and the Sea Water Pump, when the set quantity of dilution
seawater is added. Moreover the Multi-point Ball Level Switch is also designed to stop the plant in case of treatment tank
overflow (refer to
PCB CONTROL PANEL – Functional Description
section). Once filled the Treatment Tank, the
Main
Control Box
, to which is assigned the management of all the plant parts, activates the
Macerating Pump
, installed on the Main
Unit. This pump aspires the water to be treated from the treatment tank and resend it to the tank. Thanks to the thus realized
recirculation, the sewage is further macerated and mixed. This operation activates the sewage treatment process that requires
a certain time frame, to be completed successfully. Therefore, once stopped the macerating pump, the sewage is left inside the
tank for a further period of time. During this phase there is a separation of the clarified water from the residual sludge that

The additional unit is standard supplied with all components as loose parts, but on request it can be supplied in any
customizable common skid configurations.

It is important to know dimensions of the storage tank to evaluate type of sensors to supply and fit.
