Plant Description
The Model XC was designed to purify, through the passage of semipermeable membranes, the water pushed by a pressure pump.
The XC10.000 system is mounted on an aluminum frame, and is composed of the following elements:
• Solenoid valve (24V solenoid valve) – this valve is normally closed, it allows the passage of water in the system only with the electric motor running.
• Multistage electric pump, allows the system to reach an operating pressure of 12/15 Bar.
• 4 membrane container in high pressure 4040 VTR (maximum tolerated pressure 400 psi, about 27 bar).
• 4 4040 membrane (mod. BW 4040 CSM) with 98% rejection percentage and a filtering capacity of 1000 liters / hour.
• A pressure switch that allows you to stop the system when there is no request or when the tank is full and to restart the machine automatically.
• Control valve – is the handwheel valve that allows the system to be pressurized (12/15 bar).
• The pre-filtration of this system consists of 2 20 ”sediment filters (1 BIG 20 micron and n.1 BIG 5 microns) to remove solid suspensions and particulates from the water that can damage the membranes and the pressure pump.
• A constant dosing pump to dose antiscalant products and / or ph + (on request if necessary)
Correct start-up of the plant
Before starting the system, fully open (turning counterclockwise) the control valve.
Make sure that the mains water tap (system supply) is open.
Start the system electrically (start button) and wait for the water to come out of the drain pipe.
Start closing the control valve (turning clockwise) slowly until the pressure gauge reaches 10/12 bar.
ATTENTION never to exceed this pressure limit and not to completely close the control valve, otherwise there is a risk of damage
irreparably the membrane.
The system is started and automatically acts on requests.
Applications
Refinement of drinking water, elimination of impurities, chlorine, chlorine derivatives, pesticides, insecticides, fungicides, heavy metals, microorganisms.
In all processes in which the use of demineralized water is foreseen, production of drinking water from wells or sources with values within the limits of the operating conditions.
Maintenance
Replacement of prefilters approximately every three months.
Replacement of osmotic membranes approximately every 5 years.
Periodic washing and disinfection of the membrane;
Periodically, by acting on the control valve, the membranes can be washed as follows:
With the system running, open (by turning counterclockwise) the control valve and leave it in the fully open position for about five minutes,
this allows the membranes to get rid of any micro sediments.
When the operation is complete, reposition the control valve so that the system pressure returns to the operating values (10/11 bar).
Reference directives
The system is built in accordance with the Ministerial Decree 443/90, to directives 2006/42 / EC – 73/23 / EC -2004 / 108 / EC and is excluded from Directive 97/23 / EC (so-called “PED”)
relating to pressure equipment as Article 3 of the Directive itself applies.
