ProMinent

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 concentration.
