AUTOMATION AND FUNCTIONING

1. The system consists of stainless steel tanks and an iron frame painted with paints resistant to the corrosive agents in the effluent to be treated. It has three parts: the first part includes the concrete tanks to be provided by the customer; the second is the stainless steel tanks supplied by us to be installed in the ground; lastly, the technical module of stainless steel sheet is to be installed above ground. The latter will be set on top of the aeration tank and connected by pipes to the tanks underneath.


2. Upstream of our system, a primary separation and flow-breaker tank will be needed; from here the effluent will flow into the homogenization tank. This tank must have a capacity equal to half the daily quantity of effluent to be treated.


3. The lifting pump and control floats will be placed in the homogenization tank. The recessed-impeller lifting pump can lift solid materials up to 1.5 cm2.



DESCRIPTION OF SYSTEM WITH SEWER WITHOUT IMHOFF TANKS



1 - NATURAL SEPARATION
The effluent from the sewer will flow into a separation and flow-breaker tank. From here it will flow into the homogenization tank through special pipes. The tank will contain the loading pump equipped with a level gauge. The loading pump will send the effluent into the buried primary tank, the “aeration tank”.

2 – AERATION
The effluent automatically held in aeration for a specific amount of time spills over into the settling tank, in which the mixture of sludge and water is separated by gravity and the sludge precipitates to the bottom of the tank; the water spills over into the chlorination and disinfection tank.

3 – RECIRCULATION OF SLUDGE BY PUMP
The sludge recirculation pump is situated in the settling tank; it is controlled by a cyclical timer which controls the quantity of sludge to be recirculated.

4 – SLUDGE TREATMENT
The extra sludge produced is automatically sent into the stabilization tank situated to the side of the settling tank.
When the chemical-physical tank is full, it will automatically control the stabilization process which, using dosing pumps, introduces the reagents necessary for the process. After this, the pump will empty the chemical-physical tank, sending the sludge into the percolation bags situated close to the system. Then a new treatment cycle will begin.
The effluent that seeps out of the bags is sent back to the homogenization tank.
The bags will be replaced depending on the types of effluent.

5 – RECYCLING OF TREATED WATER
The treated water can be reused for purposes other than for household uses; for example, it can be used for washing storage yards, watering gardens, and washing cars.
To do this, a pump with a level gauge is inserted into the pit after chlorination.

6 – ADVANTAGES OF CHOOSING THIS SYSTEM
The advantages of our system may be summed up as follows:
– Installation simplicity: a concrete or other kind of base is sufficient
– Ability to move the system with great ease according to future needs: just empty it and move it to its new position
– Self-cleaning system: does not require any emptying or other, even more expensive, operations
– Simple sludge extraction system, which can be done by a single person
– Option to check it by telephone and act in real time depending on needs
– It is the only integrated system with biological, chemical-physical, and natural primary sedimentation treatments
– Can be installed anywhere; all that is needed is a 6KW 3-phase +N electrical line; the system is entirely closed
– Does not emit bad odors and is very quiet
– No building licenses or other documents are necessary for its installation.
