4 Correct usage
UO SMALL is suitable for the treatment of non-ferrous and bacteriologically pure water. Any other
use that is not approved in writing by our technical service is assumed non-compliant. For special
applications with water having different characteristics, you should contact our technical service,
which can indicate the optimal calibration of the system or any necessary additions on the basis of
a thorough chemical and bacteriological analysis.
The water to be treated must be consistent with that identified in Leg. Decree 31/01 and
subsequent amendments. It is critical that the installer knows and understands Ministerial Decree

5.1 The treatment of the water
The UO SMALL unit is designed for the treatment of technical waters; it represents a technological
solution for the treatment of municipal water and adds value to the local resource as the filters
applied at the extraction point enhance the water and make for a more satisfying consumption of the
water resources. It is known that potable water analysed at the tap, while respecting the chemical
and physical parameters within the limits provided by law, may have unpleasant odours and traces
of unwanted substances and biological contaminants.
The issues relating to the health aspects of municipal water are essentially two:
1. The condition of the conduits: at least 30% of water is lost between the source and the tap;
older pipes may release materials that are carried by the water or inorganic and organic trace
substances may be accidentally introduced during maintenance work;
2. Chlorine: most purification systems employ chlorination processes. Substances such as
sodium hypochlorite or chlorine dioxide, which by their unstable nature dismutate into chlorine
(used to kill bacteria) and chloride, are added in such quantities as to ensure the bactericidal action
up to the point of extraction. The chlorine ensures the safety of the water because it runs with water
right up to the tap. It is therefore essential for the protection of public health in order to ensure
bacteriological control. Unfortunately it releases an unpleasant odour that combines with other
organic gases to alter the organoleptic properties of water.
The purpose in designing the UO SMALL is to present the consumer with a solution that allows a
finishing system, (refinement) of municipal water at the end of its journey through the pipes in
order to enhance the organoleptic properties without altering the saline content. It is therefore
suitable for all aqueduct waters for technical use, and at the same time represents a solution to any
real or suspected problem, foreseeable or unforeseeable.
The treatment carried out on the water can be summarised as follows:
1. Elimination of all suspended impurities;
2. Elimination of chlorine taste and odour
The UO SMALL system is therefore able to be used in order to deprive water of chlorine smells and
any substances in suspension. A refinement process, therefore, at the end of the passage through the
tubes in order to enhance the organoleptic properties of potable water, without altering the saline
content.
The UO SMALL system can only accept input water as defined in Directive 98/83/EC of 03/11/98,
or Leg. Decree 31/2001.
The filter traps suspended matter down to 0.005 microns, and according to tests conducted at
Serchem Laboratory, showed total effectiveness against chemicals such as chlorine, derivatives of
microorganisms and large organic molecules that may be present in very low concentrations in
potable water distributed through urban networks.

5.1.1 Pre-filtration
This is the first stage. The incoming water is passed through a carbon filter (polypropylene on
request). Microfiltration is crucial before introducing the water into the RO unit as particles larger
than 5 microns may damage the membranes. The filtration elements combine the proven depth filter
technology with a design concept that eliminates the entire core for a solution which is affordable,
convenient, efficient and environmentally friendly in applications with high flow rates. Adsorption
with activated carbon is a process where a solid is used for the removal of a soluble substance from
the water.
In this process, activated carbon is the solid. It is specifically produced to have a very large internal
surface area (500–1500 m2/g). This high internal area surface makes activated carbon ideal for
adsorption. The activated carbon used is Granular Activated Carbon (GAC). This version GAC is
the most widely used in water treatment and according to documentary evidence and scientific data,
it adsorbs the following:
mineral oils
Poly aromatic hydrocarbons (PACs)
Phenyl chlorides
This filter allows the correct and complete removal of chlorine.
For polypropylene filters, the filtration element is a septum in polypropylene with low pressure loss
so that a smaller number of filtration elements is required for the same flow rate. The filtration
elements are produced according to highest standards of quality and cleanliness.

5.1.2 Reverse Osmosis
This is the second stage. The water emanating from the pre-filtration stage is sent to the two reverse
osmosis membranes made of vegetable fibres (polyamide) and conserved in a natural manner. The
membranes have also passed the usage admissibility tests by the Food and Drug Administration
(FDA). Reverse osmosis is a process of separation of foreign bodies from the water through the use
of semipermeable membranes. These structures allow water to pass through them while removing
dissolved mineral elements, pollutants, viruses and bacteria. Consider a container divided into two
compartments by a semipermeable membrane, we see that the pure water A from osmosis tends to
pass into the saline solution B, increasing its level until reaching a hydrostatic pressure (referred to
as the osmotic pressure of the solution) that balances the system and stops the passage of pure
water.
If a pressure greater than the osmotic pressure is applied to the saline solution B, the pure water
tends to return to A, resulting in the phenomenon of reverse osmosis (i.e., opposite to the natural
phenomenon). (fig. 5.1.2).
The reverse osmosis treatment therefore involves forcing water through a semipermeable membrane
to separate dissolved foreign bodies, both organic and inorganic in nature.
Despite having a minimal pore size, reverse osmosis does not operate like conventional filtration,
but rather as "cross-flow filtration".
In conventional filtration, the entire aqueous solution to be filtered is forced through the filtration
medium and any impurities too large to pass through the pores of the filter medium is retained or
trapped inside the medium itself .
In cross-flow filtration, there are two output streams from the system: the "concentrate" or the
stream that contains the impurities that are rejected or do not pass through the membrane, and the
"permeate" or the stream that is pushed through the membrane.

5.2.4 Technical Characteristics of the osmosis unit
Vessel
Particular attention has been devoted to the vessel made of stainless steel 304. It has an internal
system that prevents the telescopic effect of the membrane due to the higher pressures generated as
the membrane becomes more and more clogged. The frontal compartment allows easy inspection
and replacement of the membrane without removing the unit from its housing.
Membrane
Produces a quantity of permeate equal to 150 litres/hour using only one selective wound spiral
membrane in polyamide (PA), type 3512 650GDP.
•Membrane type: Thin-film composite
•Membrane material: Polyamide
•Configuration of the elements; wound spiral
•Maximum pressure 10 bar
•Maximum operating temperature: 45°C
•pH: 3-10
•Maximum turbidity; 1.0 NTU
•Maximum SDI: 5.0
•Maximum chlorine concentration: 0.1 mg/lt
Flood detector
To render the working area safer and prevent damage to the system, the machine is equipped with a
flood detector.
Differential pressure switch
The differential pressure switch is used to activate and deactivate the pump motor that pressurises
the membranes when a command signal is received.
The differential is divided into two signals:
stop signal, when the pressure of the circuit which includes the expansion vessel reaches the
preset value (e.g., 3 bar), the machine stops. The value can be changed with a standard Phillips
screwdriver.

17/38
on signal, occurs when the pressure falls within a range set by the manufacturer
or changed by the installer if necessary.
