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.

- Operating pressure inlet 0 - 8 bar
- Operating pressures outlet 2 - 5 bar
- Operation temperature 1 - 60°C
- Material Epoxy / Fibre glass / PP AISI 304 or 316L
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 DGS is a modular water de-aeration system based on membrane contactors. The skit is designed to grant low running costs compared to other methods based on high efficiency of the membrane contactors. Very low residual oxygen values are achieved with small energy and purge gas consumption (CO2 or N2).
Easy upgrading of capacity by adding contactors, full automatic and maintenance free operation, short run up time, variable capacity range and a small foot print are important advantages achieved due to the membrane contactors.
The DGS system is a modularly constructed water de-aeration skit. Due to high efficient contactors, so called hydrophobe hollow fibre membranes a fast exchange of gas out of the water is possible. The water is flowing along the outer side of the hollow fiber by the cross-flow principle. Through the inner side of the hollow fibre purge gas (CO2 or N2) is flowing at low pressure and sucked out by a vacuum pump. Due to this, the partial pressure of the oxygen inside the hollow fibre is decreased almost to zero. The partial pressure difference between both sides forces the oxygen to percolate. The membrane material is hydro-phobe Polypropylene which can be passed only by gases. Thousands of hollow fibres bound together form a contactor. The high surface area compared to the small volume are the main reason for the high efficiency and low running costs. Depending on required residual oxygen values and max. capacity the number of contactors is calculated and respective arranged. An optional remote access service kit allows software updating and trouble shooting within a few hours.

The full automatic System measures and controls the content of CO2. It works without losses and is fully CIP capable.
Due to its compact and modular design, it can be easily integrated into any existing plant system.
The oxygen pressure is set by a stainless steel pressure control valve so that the system works in the defined range and the modulating valve with constant conditions. The quantity of water and oxygen is measured by flow meters and the amount of oxygen is set by a pneumatic control valve. In the Venturi-Vortex injector the oxygen and water are mixed together. The combination of venturi and vortex effects enables a very fine and homogeneous spreading of the oxygen in the water. The solubility of oxygen in the water depends on pressure and temperature. Thus the Centec Venturi-Vortex injector is designed according to it in order to guarantee a perfect solution of oxygen. The Venturi-Vortex injector is always integrated in the CIP of the water pipe. The system can be combined with a booster pump, chiller and buffer tank in front of a filler

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 Rhotec density sensor and transmitter is ideally suited for quantitative process monitoring and controlling in beverage, brewing, diary, chemical/pharmaceutical and related industries where two-component processes need to be measured accurately.
The Rhotec density sensor is a highly precise means of determining the density of liquids, even under extreme process conditions. The density measurement is achieved through the use of an electro-magnetic oscillating "U"-shaped tube. As the process medium flows through the "U"-shaped tube, the oscillation frequency is measured. The oscillation frequency is affected by any changes in density and measured accordingly. The temperature dependence of density measurements is compensated through the electronic measurement of parallel PT1000 temperature elements. From these measurement signals, calculated concentrations are obtained and displayed in Mass%, Volume%, oBrix, %Extract or other density calculable quantities of the measured medium. The use of this technology with specific measurement software has a proven track record for liquids with dissolved and un-dissolved components, both organic and inorganic.

In combination of Sonatec sensor with Rhotec density sensor, three-component systems can be accurately measured and determined.
In combination of Sonatec sensor with Rhotec density sensor, three-component systems can be accurately measured and determined.
The Sonatec Ultrasonic Concentration Sensor is a highly precise means of determining the sound velocity of liquids. Like density measurements, sound velocity is a material and concentration dependent quantity which can be used for determining the concentration of a liquid. The propagation time of a piezo-ceramic generated sound pulse is measured between the prongs of a fork-shaped measuring head installed directly in the process. As this propagation time changes, the sound velocity and resulting concentration changes are measured. The temperature dependence of the sound velocity measurement is compensated through the electronic measurement of parallel PT1000 temperature elements. From these measurement signals, calculated concentrations are obtained and displayed in Mass%, Volume%, °Brix, %Extract or other sound velocity calculable quantities of the measured medium. Due to the simple mechanical design without any movable parts, the sensor is very reliable and virtually maintenance free. The use of this technology with specific measurement software has a proven track record for liquids with dissolved and un-dissolved components, both organic and inorganic.

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.
