Hazardous to health due to contaminated drinking water!  The

system may only be installed by a specialist company. The oper-

ation manual must be strictly adhered to! Ensure that there is

sufficient flow. The pertinent guidelines must be followed for

starting-up after extended periods of standstill. Inspections and

maintenance must be performed at the intervals specified!

B Basic information

1 | Laws, regulations, standards

In the interest of good health, rules cannot be ignored when it

comes to the processing of drinking water. This operation man-

ual takes into consideration the current regulations and stipu-

lates information that you will need for the safe operation of your

water treatment system.

Among other things, the regulations stipulate that

 only approved companies are permitted to make major modi-

fications to water supply facilities

 and that tests, inspections and maintenance on installed de-

vices are to be performed at regular intervals.

2 | Water

Due to dynamic substance and water cycles, harmful elements,

which are only partly and only slowly biodegradable are increas-

ingly released into nature. Over time, these elements therefore

accumulate in ground and surface water. Removing them again

from natural water bodies represents a particular challenge.

Grünbeck rises to this challenge and aims at generating unpol-

luted drinking and process water.

The water works provide us with pure drinking water that is suit-

able for consumption. However, if the water is to be used for

technical purposes, further treatment is frequently required.

Fig. B-2: Reverse osmosis principle

In the osmosis process, watery solutions of different concentra-

tions are separated by a semi-permeable membrane. In keeping

with the law of nature, the concentrations try to equalise. On the

side of the higher original concentration, the so-called "osmotic"

pressure is generated.

In case of reverse osmosis, this osmotic pressure is countered

by a higher pressure. The consequence: the process proceeds

in the reverse direction. A particular advantage of the reverse

osmosis technology compared to other water treatment pro-

cesses is the fact that - apart from the removal of dissolved salts

- bacteria, germs and dissolved organic substances are also re-

duced.

covery). During the permeate production, this portion of the wa-

ter flow permanently flows to the drain. The volume flow is sub-

ject to the system size. In case of tank "full" as well as in case of

a system failure, the valve always opens the entire cross section

in combination with the solenoid valve for feed water.

4 | Appropriate application

The reserve osmosis system is designed for the demineralisa-

tion of drinking water according to the German Drinking Water

Ordinance (TrinkwV). The generated water is primarily used for

industrial applications.

A corresponding pre-treatment is required and the application

limits (paragraph 5) must be adhered to.





Note: In case of water that does not comply with the stipulations

of the German Drinking Water Ordinance (TrinkwV), a water

analysis is required beforehand.

The continuous permeate capacity is subject to the temperature

and was defined at 15°C. The permeate capacity decreases by

up to 3 % per degree centigrade of the feed water temperature .





Note: This reverse osmosis system adjusts the permeate capac-

ity automatically subject to the temperature. The recovery (con-

centrate to drain) as well as the concentrate recirculation are

adapted to the modified permeate capacity.

The system is adjusted to the permeate requirements to be ex-

pected at the installation site, it is not suitable for major deviations.

The system may only be operated if all components are installed

properly. Safety devices and equipment must NEVER be re-

moved, bridged or tampered with.

Appropriate application of the device also implies that the infor-

mation contained in this operation manual and all safety guide-

lines applying at the installation site be observed. Furthermore,

the maintenance and inspection intervals have to be observed.

4.1 System idle time

If the system is out of operation for more than 14 days, it must

be preserved by Grünbeck's technical customer service/author-

ised service company. The maximum time, the system can re-

main in the preserved condition is 6 months.

In case the down time is longer, the system must be preserved

again in regular intervals by Grünbeck's technical customer ser-

vice/authorised service company. Prior to resuming operation,

the preserving agent must be flushed from the system.

5 | Application limits

For the application of the reverse osmosis system, the limit val-

ues stipulated in the German Drinking Water Ordinance repre-

sent the upper limits for the admissible substances contained in

the water.

 Total hardness < 0.1 °dH1)

(0.18 °f; 0.018 mmol/l)

 Free chlorine not detectable

 Iron < 0.10 mg/l

 Manganese < 0.05 mg/l

 Silicate < 15 mg/l

 Chlorine dioxide not detectable

 Turbidity < 1 FTU

 Colloid index (SDI) < 3

 pH range 3-9

1) Different application limits for the total hardness do apply for

the optional pre-treatment AVRO resp. antiscalant.





Note: The permeate originating from the reverse osmosis sys-

tem is not potable but requires additional treatment (blending,

hardening) if it is to be used as drinking water.

erating state and system values. Voltage-free contacts to re-

lay advance warnings and safety shut-downs. Digital input for

priority permeate production in times when electricity tariffs

are low (smart metering). Fully automatic monitoring and con-

trol of the system parameters permeate flow, monitoring of

the permeate conductivity by means of limit value default set-

tings in the control unit, recovery, concentrate recirculation

and pump frequency (subject to the water temperature). Re-

cording of measured data on integrated SD card. Possibility

to interconnect systems installed upstream or downstream

(water softener, dosing system, permeate tank, pressure

booster) and to operate them by remote control.
