Abstract
In this paper, the reverse osmosis desalination plants are more important in the life for drinking water which
has large effect on human health. The manual operation of these plants may be causes salt water which is
toxic to humans this is because of the body is incapable to get remove of the salt that derives from plants.
Therefore, the kidneys generally eliminate extra salt by creating urine, nevertheless the body wants freshwater
to dilute the salts in the body in order the kidneys are working correctly. Here, in order to enhance the
operation of these RO plants, the programmable logic control is used to operate the plants automatically
with high accuracy to get Healthy and drinkable water. The proposed method of this paper is applied by
using Ladder language for PLC.
Key words: reverse osmosis, desalinations plants, PLC,

Introduction
Reverse osmosis (RO) is verified to be the greatest dependable, charge actual, and energy effectual
in making drinking water related to additional distillation knowledges. Reverse Osmosis Distillation
station which frequently applied in productions. This method demonstrates an combined
mechanization scheme which can simplify monitor and control of whole Reverse Osmosis system
based on plc.
Although about seventy percent of the Earth’s superficial is protected by water, just 2.3% is drinking
water (Chen, Jiang, Ye, Yang, & Hou, 2019), and it is projected that just 2% of this is simply nearby
(Gude & Muire, 2021). Forty percent of the world populace presently exists in dry areas which drink
water is scarce (Harby, Ali, & Almohammadi, 2021; Soliman et al., 2021). Moreover, a growth of
deficiencies universal, pliability decrease to variation from unadventurous water properties, have
amplified requirement on distillation knowledges, which employment is affect by financial,
conservation, and radical issues (Ibrahim et al., 2021; Yang & Chen, 2021).. It is predictable that 2/3
of the world populace would counteracted deficiencies of water supply (Tappe, 2020), that
administrations should found useful strategies that worries on water admission by the lowliest
civilizations (Voutchkov, 2018; Zetland, 2021). the convenience and sustainable group for all dissimilar
water organization plans (Leijon & Boström, 2018), to realizing the target of maintainable growth (Eke,
Yusuf, Giwa, & Sodiq, 2020). though station with the maximum volume are unusual, it need to install
large capacity (Nassrullah, Anis, Hashaikeh, & Hilal, 2020; Pan, Haddad, Kumar, & Wang, 2020).

Theoretical background
The main advantages of PLCs are:
Easy to program, operate, maintain and repair.
More durable and less expensive for controlling complex systems.
allows for fast and easy online changes in relay ladder logic to meet the changing needs of the
process.
Flexible and can be reapplied to control other systems quickly and easily.
Easy to trouble shoot, so the programming becomes easier and reduce downtime.

Proposed method:
Reverse Osmosis Desalination Plants are more population in the world to produce the water valid for
drinking. Chemically, these plants need advance equipment for testing the water. In addition, for
operation the system with high accurate and get good results, the plants should be operating
automatically not manually. Therefore, the smart system based on PLC is used for running full
automatic. PLC is the programmable logic controller which is widely used in the industrial system and
had multifunction. The proposed method is shown in figure 1 using WPL SOFT program.

Simulation results:
The simulation system of this proposed method is shown in figure 2. The engineering diagram in figure
2 had the ability to control the plants automatically without need to the workers. The instruction list
and the monitoring of desalination pumps are shown in figures 3,4 respectively

Conclusion
PLC is widely use in the chemical system for enhancement the efficiency and increasing the
effectiveness with more accuracy. In this suggested method, the PLC is applied to RO system for
getting to drink and health water based on the the automatic operating system. In addition, the
amount of the chemical material which adding to the RO desalination system are more accurate
depending on the programming of PLC.
