Prominent water treatment plant, consisting of: 1. Softening: The raw
water is fed into the double softener. Only one bottle is ever in
operation and the other is in regeneration or stand-by. In the
softener, calcium and magnesium are replaced by sodium. The system has
a volume counter that switches to the other bottle when the preset
quantity is reached. Regeneration takes place with saline solution
from the brine tank. The value at the outlet is 0°dH. 2. reverse
osmosis: Reverse osmosis fills the permeate tank with demineralised
water, so-called permeate. Depending on the raw water quality, water
temperature, condition of the membrane and correct setting, different
conductance values and operating pressures result. The following flow
rates are set during commissioning: Permeate 600 l/h, concentrate 200
l/h, corresponding to a yield of 75%. 3. permeate tank and
ozonisation: The unpressurised 500 l permeate tank has an adjustable
level control. For treatment with ozone, the water in the permeate
tank is circulated via an adjustable ozone feed point. The ozone is
generated from air in the ozone generation system by means of a silent
electrical discharge and is available as an ozone-air mixture. The air
and the undissolved ozone rise upwards in the permeate tank and are
discharged via the residual ozone destroyer. A redox potential and
ozone measurement is carried out after the centrifugal pump for
monitoring purposes. The ozone dosage is set via the touch panel. You
can choose between regulation via the redox potential or the ozone
