Description
In the reversed osmosis process water is forced across a membrane, leaving the impurities behind. The permeability of the membrane can be so small, that practically all impurities, salt molecules, bacteria are being separated from the water
A water treatment process utilizing a membrane to remove dissolved minerals. The process of osmosis occurs in nature, when a pure solution is separated from a saline solution by a semi-permeable membrane. The pure solution passes through the membrane until a pressure differential is reached called the Osmotic Pressure. At this pressure differential, determined by the constituents and concentrations in the saline solution, osmosis stops. Reverse Osmosis reverses this process by applying pressure in excess of the osmotic pressure to the saline solution, forcing water through the membrane. As this occurs, most dissolved solids remain behind and are carried out with the reject stream. The purified water can then be utilized as needed.

Description
The plants are designed as weak- and strong acid cation exchangers, weak- and strong basic anion as well as mixed bed exchangers.
The used technologies are co-flow, counter-flow or floating bed exchangers.
The resins used in closed filter vessels carry out the decarbonisation- or desalination process by exchanging ions bound to the resin against ions of the salts dissolved in the water.
Ion Exchangers are insoluble granular substances which have in their molecular structure acidic or basic radicals that can exchange. The positive or negative ions fixed on these radicals are replaced by ions of the same sign in solution in the liquid in contact with them. The ion exchange is complete without deterioration or solubilization nor changing the total number of ions in the liquid before the exchange.The ion exchange substances are used almost exclusively under the name of resins. There are two categories of it: the resins of the gel type and those of the macroporous or loosely cross-linked type. Their basic structure is identical: the macromolecular structure is obtained in both cases by copolymerization. The difference between them lies in their porosity.

Description
The Centec CIP units are very flexible systems for the fully automated cleaning of production facilities. Product leftovers and coats are removed to archive a clean biologically and physically surface. Therefor the Centec CIP systems are optimized regarding the amount of used cleaning liquid, temperature, concentration and process circulating time . CIP stations can integrated at a central place (i.e. ideally in the center of a building or the production plant, or decentralized (beside the specified production units). The cleaning liquids are rejected after the use (lost CIP) or can be re-use if stored (batch CIP).
For the execution of the cleaning process, different components as for example tanks, pumps, valves, heat exchangers, PLC and control software are necessary to provide the cleaning liquids to the units to be cleaned. The units can be placed centrally for all production plants or decentralized, i.e. for part of the production units with the different capacities. The cleaning liquids can be used in circulation mode with suitable batch tanks or in direct consumption. The technical optimization of the process reduces the mixtures of the single cleaning liquid. According to the given procedure technology the cleaning capacities are customized and controlled concerning the necessary speed.

Description
The O2-transmitter Oxytrans TR measures continuously and exactly the content of oxygen in liquids and gases. The sensor is especially designed for breweries and further applications with high requirements, e.g. power plants or bioreactors. The optical principle of measurement is based on the effect of dynamic luminescence quenching by molecular oxygen. The indicator layer on the glass installed in the measuring head is illuminated with a blue-green-light. With this, the indicator molecules are transferred into an excited state and emit a red light and detected by the internal detector. If oxygen is in the medium, this luminescence effect is prevented by energy transfer to the oxygen molecule. After the collision with the indicator molecule the oxygen molecule is transferred from its ground state (triplet state) to its excited singlet state. As a result, the indicator molecule does not emit luminescence and the measurable luminescence signal decreases linear to existing oxygen concentration. This decreasement is the basis for the oxygen calculation. The O2-concentration can be displayed in different units like ppb, ppm, %oxygen, etc.
