Durum: ikinci el, Üretim yılı: 2007, Prominent water treatment system, consisting of: 1. Softening: Raw water is supplied to the twin softener unit. Only one vessel is in operation at any time, while the other is either regenerating or on standby. In the softener, calcium and magnesium are replaced with sodium. The system features volumetric control that switches to the other vessel once the preset volume is reached. Regeneration takes place using brine from the brine tank. The hardness at the outlet is 0° dH. 2. Reverse Osmosis: The reverse osmosis unit fills the permeate tank with demineralized water (permeate). Conductivity levels and operating pressures vary depending on raw water quality, water temperature, membrane condition, and correct adjustment. Upon commissioning, the following flow rates are set: permeate 600 l/h, concentrate 200 l/h, resulting in a yield of 75%. 3. Permeate Tank and Ozonation: The non-pressurized 500 l permeate tank has an adjustable level control system. For ozonation, water in the permeate tank is circulated via a variable ozone dosing point. Ozone is generated in the ozone generator via silent electrical discharge from air and is supplied as an ozone-air mixture. Air and undissolved ozone rise to the top of the permeate tank and are vented via the residual ozone destructor. Redox potential and ozone measurements are taken after the centrifugal pump for monitoring purposes. Ozone dosing is set via the touch panel, with control selectable by either redox potential or ozone concentration.
