Recently, reverse osmosis has been developing into one of the most important technologies<br />
in the <strong>product</strong>ion of highly pure water for a variety of purposes. Whether for<br />
the <strong>product</strong>ion of drinking water, the <strong>product</strong>ion of boiler feed water, the purification<br />
of process water or for the <strong>product</strong>ion of highly pure water for the semiconductor<br />
and pharmaceutical industry - nowadays in almost all branches of industry modern<br />
reverse osmosis plants are used.<br />
The final target is to run these plants under environmentally friendly and beneficial<br />
economical conditions. Special attention is given to an efficient utilization of energy<br />
as well as saving precious water.<br />
Depending on the targeted application, reverse osmosis plants can process many<br />
different types of impure water, such as for example surface water, well water, sea<br />
water and waste water of many diverse origins. Each supply water possesses different<br />
characteristics based its the composition of the organic and inorganic components.<br />
With the knowledge of these components and by considering plant specific parameters<br />
it is possible to develop an efficient and effective treatment concept achieving<br />
an optimal economic operation and maximum operational reliability of a plant.<br />
The high level of experience of our engineers, the special equipment of our laboratories,<br />
our decades’-long world-wide company know-how as well as the uncompromising<br />
quality of our <strong>product</strong>s make <strong>Kurita</strong> one of the most competent partners for the<br />
treatment and operation of your reverse osmosis plant.<br />
A thorough understanding of the design and the operation of a RO plant is the basis<br />
for a successful treatment concept! According to this principle, we perform the following<br />
investigations in our scientific research laboratories:<br />
Analysis of water and deposits<br />
Autopsy of membranes<br />
Flat <strong>sheet</strong> tests<br />
Cleaning tests<br />
Microscopic investigations<br />
Surface analysis<br />
Based on these comprehensive preliminary investigations it is possible to select the<br />
most suitable biocides, antiscalants and cleaning chemicals and, thus, to operate a<br />
plant in an economical and environmental friendly way.<br />

Regular monitoring of the operational performance of the plant as well as performing<br />
regular maintenance are basic conditions for a trouble-free operation. One of the<br />
main goals for trouble-free operation is to effectively protect the membranes against<br />
fouling and scaling. This is to maximize the life span and run length of the membranes.<br />
Our research and development activities have resulted in a complete line-up of<br />
many diverse antiscalants in order to prevent all types of possible scaling on the<br />
membranes effectively. We have directed our special attention to the selection of the<br />
most suitable antiscalant for each specific application and supply water quality. Our<br />
antiscalants offer excellent inhibiting effects for:<br />
Colloids and suspended matter<br />
Iron and manganese<br />
Calcium carbonate<br />
Calcium sulfate<br />
Strontium sulfate<br />
Barium sulfate<br />
Silicate<br />
Our <strong>product</strong> portfolio contains antiscalants with NSF-certification.<br />
Biological, organic and inorganic contaminations present in the supply-water are<br />
deposited on the surface of the membranes. The deposition of those contaminations<br />
from the impure supply water on the membrane surface is generally referred to as<br />
„fouling“.<br />
If organic contaminations from the impure supply water are adsorbed, it is often<br />
referred to as „organic fouling“. The adsorption of micro-organisms to the surface of<br />
membranes is designated as „biofouling“. Embedded in a gel, the micro-organisms<br />
deposit from extracellular polymers as biofilm on the surface of a membrane. Biofouling<br />
is particularly problematic since micro-organisms can reproduce on the membrane<br />
surface and therefore substantially affect the efficiency of the plant.<br />
In order to prevent the process of biofouling effectively, the addition of biocides is<br />
essential. For this, <strong>Kurita</strong> has developed special biocides which contribute to the<br />
economical operation of your reverse osmosis plant. Our technology is characterized<br />
by:<br />
Low dosing rates<br />
Dispersion of existing biofilms<br />
Prevention of germ resistance<br />

To achieve a long run length of the RO membranes, it is beneficial to reduce the load<br />
on the membranes as much as possible by using an effective pretreatment of the<br />
feedwater. Depending on the raw-water quality, this pretreatment could consist of<br />
coagulation, flocculation, sedimentation, filtration etc.<br />
<strong>Kurita</strong> possesses expert-knowledge and has developed special and innovative <strong>product</strong>s<br />
for this application range. On the basis of diverse analytical test-observations<br />
and calculations, such as Silt Density Index, a selection of the best performing<br />
<strong>product</strong>s could already be achieved in the laboratory testing stage.<br />
An effective pre-treatment of water is the basis for a smooth operation of the reverse<br />
osmosis plant. However, it cannot be prevented that fouling processes and scaling<br />
processes on membranes result in a decrease of performance during the time of<br />
operation. This increases the energy demand of the plant while the quality of the<br />
produced water diminishes. The loss of performance results from colloidal and microbiological<br />
depositions as well as from deposits of metal hydroxides. In addition,<br />
deposits of CaCO 3, CaSO 4, SiO 2, BaSO 4, CaF 2 also reduce the yield of permeate.<br />
For this reason, it is necessary to clean the membranes regularly. Specific demands<br />
require individual solutions in the establishment of the proper cleaning procedure.<br />
For this reason, we perform a range of preliminary investigations in order to develop<br />
a suitable cleaning procedure. The following aspects are of importance:<br />
Autopsy of membranes<br />
Performance tests<br />
Analysis of water<br />
Purification test<br />
Analysis of deposits<br />
Energy Considerations Increasing energy costs directly influence the costs of the <strong>product</strong>ion of reverse<br />
osmosis water. The energy consumption of the high-pressure pumps play a central<br />
role.<br />
Regular monitoring of the pressure losses across the membranes and the flow rates<br />
are important control parameters that give valuable information on possible scaling<br />
or fouling on the membranes.<br />
A further important aspect in the examination of energy consumption and saving is<br />
the preheating of the feed stream by means of waste heat from other processes as<br />
water temperature has a dramatic influence on the <strong>product</strong>ion of permeate.<br />
Best choice for you is <strong>Kurita</strong> as your partner. <strong>Kurita</strong>´s engineers look at your plant<br />
as an entire unit in order to achieve the best cost performance in an efficient and<br />
effective way.<br />
