Sea Water Desalination
Technology Introduction

2. Technology Introduction
At present, reverse osmosis method has been widely used to desalinate seawater and solve the
problem of urban residents' domestic and industrial water.
The company can provide 1 T/D ~ 10000 T/D sea water desalination devices of different specification,
medium and small desalination equipment can according to customer needs, flexible configuration of
the power supply mode, suitable for 12, 24 v dc, and other industry of different voltage and
frequency alternating current (45 v / 415 v / 380 v / 220 v / 110 v), at the same time can also provide
power supply facilities, such as solar energy, wind power, diesel generator system, equipment have
artificial semi-automatic and fully automatic control mode.
The company has passed ISO9001 quality system certification, has a professional design, research
and development team, can according to the needs of users to provide professional system design.

5. Technology Advantage
1. Compared with the traditional seawater desalination process, the operation cost can be reduced by 1-2 yuan on average, and the
investment cost can be reduced by one-fifth
2. Short process flow, low cost, low operating cost, small footprint
3. The sedimentation tank + micro filter + ultrafiltration technology adopted in the traditional process has a service life of 3 years.
This process USES quicksand filter and LISEF high-efficiency filter, with a service life of 5-10 years, simple management and
maintenance, and low labor cost
Continuous Sand Filter LISEF Self-cleaning Automatic Filter

6. CONTINUOUS SAND FILTER
Features
1. Using single filter layer, mobile filter bed filtration and special mechanical structure
technology, the filter bed itself continuous backwash update, complete automatic continuous
uninterrupted filtration
2. Low pressure turbulent filtration technology is adopted to realize the stability of operation
and water quality
3. Adopt high water tank to feed water, realize direct filtration, save energy
4. Ultra-low pressure filtration technology, inlet pressure 0.03Mpa, impact resistance
5. The whole process does not need to add medicaments, economic benefit, social benefit and
environmental protection benefit are remarkable
6. The new automatic sand filter has high filtration accuracy and stable effluent quality.
The fully automatic sand filter is a new product based on our industry experience and our own engineering experience, which
realizes the requirements of continuous filtration process and continuous stabilization of water quality. Water inlet pressure is very
low, belongs to no pressure filtration, to meet the requirements of environmental protection and energy saving. The application of
new automatic sand filter in water treatment process has reached the leading level of continuous water filtration in China.

7. LISEF high-efficiency filter
LISEF is a kind of high-capacity filter equipment that can be used for ultra-high speed processing. It
makes up for the shortcomings of the filters commonly used at present and can greatly improve the
filtration efficiency. It is a new type of filter equipment with the main purpose of removing SS， COD，
TP， water.
Product Features

one-time investment, 5-10 years
without replacement
⚫ The graphene filter material has
three-dimensional pores and good
deep filtration effect
⚫ Backflush saves water and time
⚫ compact structure, it takes
relatively small space
