2.4.1 Selcoperm

Sodium hypochlorite solution (the product) is prepared in a simple 
batch process, initiated by the level within the product tank (M).
The water for the electrochlorinator should be supplied to mains 
water supply (C) via a double non-return valve. Water enters the 
system via an isolating valve (16a). The water passes through a 
pressure reducing valve (10) to ensure a regulated pressure 
throughout the system. All water then passes through a water 
softener (4). Softened water passes into the brine tank (A), via 
isolating valve (16b) to produce a brine solution. This is regulated 
by the floater valve (21) within the brine tank (A). Saturated brine 
is then available for regeneration of the softener (4) via isolating 
valve (16c), and for the brine pump (3) via isolating valve (16d).
The process is initiated by the level sensor (25) in the product 
tank (M). When the product level falls below the start-fill level 
(25a), the water solenoid valve (5) opens, and allows softened 
water to flow through the flowmeter (6). When this water flow 
raises the magnetic float within the flowmeter (6) the flowmeter 
switch (20) is triggered and starts the brine pump (3). The pump 
doses saturated brine into this water flow via the injection valve 
(15). The resulting diluted brine solution of 20-30 g/l NaCl passes 
through the electrolyser cell (1). If no fail safe is triggered, a 
voltage is applied across the electrolyser cell (1). When the 
electrolyser cell (1) is completely filled with liquid, and the 
degassing column level sensor (9) is activated by the liquid, a 
current flows. The resulting product (sodium hypochlorite 
solution) leaves the electrolyser cell (1) and enters the 
transparent degassing column (2). Then it flows into the product 
tank (M).
When the product reaches the stop-fill level (25b) in the product 
tank (M), the process is stopped. The process is restarted when 
the product level in the tank (M) falls below the start-fill level. 
The process can also be started manually via control (28).
While the unit is generating the product, hydrogen gas produced 
in the process is removed in the degassing column (2) and is 
passed through a dual-contained seamless pipe (11) to a safe 
ventilation discharge point. An air dilution fan (19) is fitted to 
dilute the hydrogen gas to a maximum dilution of 25 % of the LEL 
(Lower Explosive Limit). The air is blown continually through the 
electrolysis and degassing chamber and through the 
dual-contained pipework to prevent localised accumulation of 
hydrogen. An air flow sensor (13) is fitted to shut down the 
electrochlorinator in case of a blockage or restriction in the 
ventilation line (12), or if the sealing cover of the electrolysis and 
degassing chamber is removed.
The electrochlorinator is fail safe. In case of faults the display on 
the control (28) shows reasons and initiates a potential-free 
contact for an output alarm.

2.4.2 Water softener

Hard water contains calcium and magnesium. The water softener 
(4) contains resin beads, which hold sodium ions. When hard 
water passes through the resin beads inside the water softener, 
the beads attract and hold the calcium and magnesium ions in 
exchange for sodium. After this ion exchange process, the water 
is soft.
Once the resin beads are loaded with calcium and magnesium 
ions, they must be regenerated so that they can continue to 
soften water. The salt in the brine tank (A) mixes with soft water to 
wash the resin beads. Only clean, soft water must be used to 
make the brine. The brine loosens the hardness minerals that 
have accumulated on the resin beads, then the system 
backwashes and flushes the hardness minerals away trough 
waste outlet (E).

Note

Leaky taps and pipes should be repaired to ensure 
proper performance of the water softener.
