4000 LPD Automatic Seawater Reverse Osmosis Drinking Water Treatment Filter Machine Desalination System


Sea water desalination system

Desalination of seawater uses desalination of seawater to produce fresh water. It is an open source incremental technology that realizes the utilization of water resources, which can increase the total amount of fresh water, and is not affected by time and space and climate. It can guarantee the stable water supply of drinking water for coastal residents and water supply for industrial boilers.

Working principle

The process of obtaining fresh water from seawater is desalination. The seawater desalination methods currently used include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method. Currently, the application of reverse osmosis membrane method and distillation method is the mainstream in the market.


The reverse osmosis seawater desalination technology has developed rapidly, and the engineering cost and operating cost have continued to decrease. The main development trend is to reduce the operating pressure of the reverse osmosis membrane, improve the recovery rate of the reverse osmosis system, cheap and efficient pretreatment technology, and enhance the system's anti-pollution ability.

Seawater Desalination System Details

KYRO-4000LPD Seawater Desalination System:

1. Capacity: 4000LPD
2. Rated power: 4.0KW/H
3. Voltage: 110V/220V/380V, 50Hz/60Hz, single phase/3phase
4. Desalting rate:>=98%
5. Water recovery rate: 30-35%
6. TDS of raw water: ≤35000PPM
7. TDS of pure water: ≤750PPM


Seawater Desalination System Features:

1. High salinity, generally about 35g/L

2. Corrosive

3. Lots of animals and plants in seawater

4. The composition of various ions in seawater isrelatively stable

5. PH value changes very few. PH value of surface seawater is between 8.1 to 8.3, deep seawater is about 7.8


Seawater Desalination System Consumable items:

There are several kinds of consumables you need to replace regularly.
a. Quartz sand: replaced about every 15 months. 50kg/bag
b. Activated carbon: replaced about every 15 months. 25kg/bag
c. Resin: replaced about every 15 months. 25L/bag
d. PP Filter cartridge: replaced about every 1 month.
e. Ro membrane: replaced about every 2 year.
We suggest you buy 1- 2 years of PP filter cartridges together with machine. Because these PP filter cartridges need to replace every month.


Seawater Desalination System Processing

Process: raw water tank + raw water pump + quartz sand filter + antiscalant system + chemical dosing system+ 1#security filter + 2#
security filter + ro system + pure water tank + UV sterilizer(ozone generator) + water supply point

Some parts function:

1. Raw water pump: provide needed pressure for every pre-treatment filter;
2. Quartz sand filter: use fiber glass as housing, fill quartz sand, it can filter big particles impurities, suspended substances, colloids etc. Important to remove iron and sediments you mentioned;^^
3. A
ntiscalant system: (It is recommended to add H2SO4 to adjust the pH value to avoid CaCO3 precipitation and reduce seawater desalination membrane fouling---cost-effective and no side-effect)
4. Security filter: prevent large particles, bacteria, viruses into RO membrane, accuracy is 5µm;
5. High pressure pump: provide needed working pressure for RO system, ensure production capacity of pure water;
6. RO system: can remove particles, colloids, organic impurities, heavy metal ions, bacteria, virus, heat source etc. harmful substances and 99% dissolved salts.
7. UV sterilizer: can continue to kill bacteria even water fill into bottled,viruses,cell damage,atc...
