90TPH Brackish Water Desalination System RO Water Treatment Plant
Reverse osmosis (RO) is a water purification technology that uses a semipermeable
membrane to remove ions, molecules and larger particles from
drinking water. In reverse osmosis, an applied pressure is used to
overcome osmotic pressure, a colligative property, that is driven
by chemical potential differences of the solvent, a thermodynamic
parameter. Reverse osmosis can remove many types of dissolved and
suspended species from water, including bacteria, and is used in
both industrial processes and the production of potable
water.
Function of Each Part of Brackish Water Treatment Plant
High Pressure Pump | Provide the high pressure to RO membrane; |
Feed Water Pump | provide the pressure to quartz sand filter/active carbon filter; |
Multi-medium Filter | get rid of turbidity, suspended matter, organic matter, colloid, ect; |
Active Carbon Filter | Remove the color, free chloride, organic matter, harmful matter, ect; |
Security Filter | prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um; |
Softener | exchange "ions" of calcium and magnesium with the most common and easiest method; |
Brackish Water Treatment System | main part of the plant. The RO membrane's desalting rate can reach 99%, removing over 99% ions. |

RO Main Features
1. Desalination rate: 97% - 99%;
2. Good water quality, low power consumption, simple operation;
3. Get rid of organics and bacteria: 98%;
4. On-line conductivity monitoring, ensure good quality of water
ouutput;
5. PLC mini PC monitor, wash RO membrane in fixed time;
6. Running in a high automatization, no pollution;
7. Drinkable without boiling, refuse incrustation scale in water
pot.
Safe Operation of Reverse Osmosis Desalination System
Although the operation of the RO system has proven reliable, there
may still be some reports of malfunctions. For example, improper
pretreatment of feed water, various operating parameters are not
controlled according to regulations, etc. Therefore, the reverse
operation of the reverse osmosis desalination system must pay
attention to the following issues:
(1) Regularly test SDI index. Excessive SDI will cause irreversible
contamination of the membrane module and shorten the service life
of the module.
(2) Control the recovery rate. The recovery rate is too high. On
the one hand, the component of insoluble salt is more than the
solubility product, forming scale. On the other hand, if the flow
rate of concentrated water in the module is too low, it is easy to
cause concentration polarization and cause scaling, which is not
conducive to the discharge of colloids and suspended solids in the
water.
(3) Pay attention to the pressure difference of the membrane
module. The initial differential pressure of the membrane module is
small. If the differential pressure increases rapidly, the membrane
module is contaminated or fouled, and the cause must be identified
and corrected.
(4) Pay attention to changes in water production and desalination
rate, which usually occur at the same time as changes in pressure
difference. If the water production and desalination rate change
significantly in a short period of time, it is necessary to check
whether the pretreatment system is operating normally, such as
whether the dosage is appropriate, whether the filter is leaking
and so on.
Deal with raw water TDS range 2000 - 20000 ppm. The capacity ranges
from 250LPH to 500TPH.
1. The brackish water system can be used for the area where
underground water in high salty and near sea. (Brackish feed water
TDS between 2000ppm and 20000ppm)
2. Our RO water system adopt the USA DOW membrane and China high
quality membrane housing , SUS316L pressure pump, SUS316 pipe and
with suitable pretreatment. Our RO machine can remove more than 97%
inorganic salt, heavy metal ion, organic matter, harmful bacteria
etc. It can make the brackish water to be drinkable water which
suitable for human consumption.
3. We can make the special and suitable brackish water system
according to customers input water quality . To make the machine
high efficient, long life span, and output water quality after our
machine can reach to the WHO drinking water standard. The brackish
water system can solve water problem which the area lack of water
4. As different place with different water quality, it is better
that customers provide us the local water quality report so that we
can give you the most suitable, economic machine and high efficient
machine.
