Desalination:

Desalination by reverse osmosis must be carried out in order to ensure minimum turbidity conditions and to remove suspended bodies or others (e.g. algae) as well as hard parts (calcium) and metals present in the water.

Filtrations:

For the filtration phase, a series of qwartz filters designed in fibreglass is foreseen.
Pre-feeding pressurisation: Two parallel pumps positioned on the pre-feeding skid « with alternating operation » are provided for pressurisation.

Reverse OSMOSIS desalination

Dopo una prima filtrazione, con filtri di 5 micron che utilizzano cartucce After an initial filtration, with 5-micron filters using PP fibre cartridges, the liquid is sent to the filtration stage on semi-permeable membranes, where the water is pressurised at approximately 64 bar in order to obtain a flow of filtered water. The energy required for the process is supplied by centrifugal or piston-type pressurisation pumps, whose parts in direct contact with the seawater are made of duplex stainless steel, equipped with a state-of-the-art energy recovery system.
Two dosing stations, one for anti-scale and one for antioxidant products, help to preserve the membranes.

All hydraulic components of the high-pressure line are made of duplex steel.
The membrane vessels are made of glass resin (fiberglass) and support a pressure above the expected operating pressure of 64 bar. The low pressure circuit is made of rigid PVC for pressure pipes.

Energy recovery :

The facility is designed with a state-of-the-art energy recovery system that directly transfers energy from the high-pressure concentrate to the salt water equivalent at the inlet.
This technology, combined with membranes that have reduced pressure losses and high-efficiency pumps, offers a significant reduction in energy consumption. This solution guarantees savings of at least 50 per cent of the absorbed electrical energy.

Flow volume:

The volume of the flow membranes will be automatic and programmable with the use of previously osmoticised water. The system includes automatic valves for the correct management of the flow volume, which are in turn controlled by the PLC and with the use of the pre-feed pump, will draw reverse osmosis water directly from the tank.

Management and control :

Il sistema di desalinizzazione dell’acqua è seguito da un quadro elettrico con unità di controllo e gestione “touchscreen" e un modem per il controllo e la programmazione remoto. La strumentazione per il controllo dei diversi flussi e pressioni verrà eseguita con traduttori che consentono la lettura e il tracking digitale.

eLisy disinfection system:

The new eLisy water disinfection system allows you to obtain purified and potable water that is perfectly clear, thanks also to an algaecide and floculant action, reducing all types of bacteria, including legionellosis, by 100%.
All 100% natural. eLisy units are designed for cleaning, disinfection and sterilisation systems with 0.05% – 1.0% salt solutions (NaCl or Kcl). The units electrolyse salt water using ceramic or polymer membranes that separate positive and negative ions.
The reactions of electrochemistry are the production of different types of active solutions. The purpose is to eliminate pathogens such as bacteria, viruses, spores, moulds and fungi, as well as cleaning and removing certain heavy metals in the water.
In recent years, however, the emergence of multi-resistant bacteria, the discovery of Legionnaires’ disease and other problems associated with chlorinated compounds have led to the search for new technologies and ways to disinfect water.

ANECO® technologies have enabled the production by electronic activation of Aneco® (HClO) known to eliminate pathogens; they produce hypochlorous acid also composed of natural sodium hypochlorite ions, with a real reduction in HAZARDS, COSTS and ENVIRONMENTAL IMPACT.

• Easy and safe to use
• Effective: Reduced contact time for sterilisation
• Biodegradable liquids
• Simplifies operating procedures and offers quick and safe benefits.

Aneco®

The strength of Aneco® (HClO) in terms of the concentration of active sodium hypochlorite (chlorine) can be adjusted as required through planned programming in the production machine. A flow regulator is installed in the hydraulic part to stop the eLisy unit in the event of a water shortage and causes the machine to restart when water flow arrives.
An on/off switch, with a power indicator, allows the eLisy unit to be manually stopped or reactivated. There are several basic models ranging from 20 to 10,000 l/h, and the production capacity will therefore vary according to requirements.

The Aneco® (HClO) produced by ANECO® is placed in a storage bin and then injected into the water system as required.
The dosing schedule will depend on the water quality and will be monitored by a flow meter connected to a dosing pump.

Based on extensive studies, the Aneco® solution (HClO) is:

• Environmentally friendly;
• Free of toxicity to humans, animals and nature;
• A powerful biocide;
• Can be safely disposed of in the sewage system;
• Very fast contact biocidal action;
• Can be used in all stages of disinfection and cleaning;
• No waste on any type of surface without a possible recommended dosage;
• Can be applied to liquids, hot or cold, on ice and still in spray form;
• Hypoallergenic;
• Produced on-site, to eliminate storage and handling of chemicals.
