||
| Dry-run protection: | Yes | ||
| Concentrate Displacement: | Concentrate Displacement unit If the product water tank ( the product water tank is not included in the offer and scope of delivery ) is full, the RO system must be flushed before standby due to the highly concentrated feed water. This must not remain in the system after standby and must be flushed out. Concentrate Displacement tank: 200 liters Float switch Multi-stage, horizontal centrifugal pump 230V AC Type P510. The Concentrate Displacement unit performs this task via the PLC control with its own special programming and with its own tank and pump. The permeate is supplied from the product water. |

||
| Conductivity display: | conductivity display on the permeate as text | ||
| Mounting – Design: | mounted in the container | ||
| Flow sensors: | 1x active digital flow transmitter (1: product / concentrate is calculated by the PLC ) |
||
| Pressure sensors: | 1x active digital pressure transmitter 0-16 bar ( inlet pressure, operating pressure ) |
||
| Permeate rejection | with permeate reject system | ||
| Feed water inlet: | stainless steel solenoid valve on the water inlet 230 V 50Hz | ||

|||
| Installation of the reverse osmosis system in a 20′ container | Installation of the system in the customer’s container – installation – PVC floor coating with floor drain ( floor drain is installed by the customer on site ) – connections and piping of the components from item 1-8. The piping is prepared internally; all connections/lines from inside to outside of the container are carried out by the customer on site. |
||
| CIP | Cleaning in Production ( chemical cleaning ) Tank 200 liters Pump, stainless steel horizontal centrifugal pump 230 V AC Cartridge filter 2.5×10 50µ. During normal operation, the membranes of the reverse osmosis system can become unusable due to mineral, biological and insoluble organic particles, resulting in a reduction of product water and/or a reduction in desalination. If a decline in water quality (conductivity) occurs in any of the units, or if changes in pressure parameters or flow rate occur, a chemical cleaning of the modules must be carried out. |
