LESSO / 22
Fertigation is a technology that combines irrigation and fertilization. With the help of an external pressure
system (or the natural drop of the terrain), the soluble solid or liquid fertilizer is evenly mixed with water in a
mixing bucket or mixing chamber according to the specific characteristics of crop fertilizer demand. After
this, is it transported to the end irrigator through the irrigation network. The fertilizer liquid penetrates into
the deep soil of the irrigation area in an even and stable manner, ensuring proper fertigation. The fertilizer
then flows out with the water, saving on water, fertilizer, labor and time, making it both efficient and
convenient. Fertigation covers the specific needs of different crops in different growth stages of water and
fertilizer, adhering to the principle of \"having many meals but little food at each\". This means crops can
fully absorb nutrients, ensuring scientific planting and controllable management, improving crop quality
and yield, and improving the utilization of fertilizer and water.
The fertigation system consists of a water supply system, variable frequency constant pressure system,
filtration system, control system (fertigation machine), irrigation pipe system and monitoring system. The
monitoring system includes temperature and humidity sensing system, weather station, and soil moisture
information station.

02 Water Supply System
The variable frequency constant pressure water supply system features a water
supply mode in which the outlet pressure remains unchanged when the water
consumption changes in the water supply network. The pressure parameters in the
pipe network can be adjusted according to the irrigation demand during different

04 Filtration System
The centrifugal filter is based on the principle of centrifugal settlement and density
difference. The water flow is stratified by a centrifugal force at a certain pressure,
so that low density water is discharged from the overflow port, and high density
sand is discharged from the bottom sand discharge port, thus completing the
sand removal process. Often used for one-stage filtration.
The grit filter provides deep vertical filtration through the formation of a sand bed
with homogeneous and equal particle size quartz sand as a filter carrier. It is often
used in two-stage filtration, and its main function is to filter organic matter and
floating matter in irrigation water.

The water flow through the laminated filter enters through the filter inlet, while the
laminated filter sheet is tightly pressed together under the action of a spring force
and hydraulic power. Impurities are intercepted at the overlapping point of the
laminated sheet, and the filtered water flows out from the main channel of the
filter. Often used for last-stage filtration.
Automatic backwash laminated filter
The design has been improved on the basis of an ordinary strainer-type filter. The
water comes in from the side, while impurities are separated through the 316
stainless steel filter and discharged through the manual flush valve at the end.
Often used for last-stage filtration.

A new form of platform providing a stable and safe operating surface for tourism, leisure and entertainment,
aquaculture cages, water side fishing, water restaurants, lookout platforms, marinas, and floating swimming
pools, the water leisure platform has gradually adapted to people's pursuit of a leisurely living environment
near the water, and is rapidly being accepted by a great variety of people. Tourism is becoming a pillar
industry in a growing number of cities. With the continuous development of the tourism industry and people's
continuous pursuit of a high-quality life, the basic supporting facilities for water entertainment are constantly
being innovated, and are changing from traditional wooden foam platforms to advanced high-density plastic
platforms. The HDPE water platform replaces the traditional foam keg float and board plane by using
integrated extrusion pipe and knurled non-slip plastic tread planes on the surface. The platform is highly
resistant to wind and waves; it is safe, reliable, widely used, environmentally-friendly, and durable.
The important difference between this product and existing products or similar products on the market is that
the structure of the components that provide buoyancy for the platform is completely different, while the
support surface of the upper structure is also of a new design. The reticulated porous structure of the support
not only makes the water flow smoother and avoids wave impact, but also connects with the tread to
combine the upper structure and the lower structure of the platform, thus enhancing the platform's ability to
resist wind and waves. This makes the platform more stable and comfortable when the wind and waves
come. The platform's upper structure is also equipped with safety guardrails and handrails at various heights.
Their number and color can also be combined in any manner, making the platform safer, more reliable, and
more aesthetically pleasing.
The traditional water platform is simple in structure, mainly consisting of floats or pontoons, wooden or steel
supports, plastic boards and other materials. These feature numerous disadvantages, such as an unstable
structure, low bearing capacity, poor wind and wave resistance, short service life and low grade.
Almost all parts of the LESSO water leisure platform system are made of the same material, that is, high
density polyethylene (HDPE). HDPE is resistant to seawater corrosion, provides good flexibility and allows for
deformation with waves, providing good wind and wave resistance for the platform.
When using the LESSO water platform, users should use an appropriate
anchoring system based on local hydrological and geological conditions. It
can be properly installed in any water area, and is suitable for resident
personnel, offshore aquaculture, and long-term bridging.

Wind-Fishery Integration
Product
introduction
Main
advantages
Wind-fishery integration refers to the overall planning of water and underwater facilities, wind turbines and
aquaculture within the scope of the wind farm, with a coordinated 3-D layout of ocean, offshore wind
power and fishery aquaculture. On the basis of aquaculture facilities and offshore wind turbines, the
integrated design is adopted to make full use of the energy advantages of wind power and the industrial
benefits of aquaculture. In this way, it enables the dual benefits of \"farming fish by electricity and
maintaining electricity by fishing\".
With recent huge investments in offshore wind power, the entire offshore wind power industry is exploring
the realization of offshore wind power, among which wind-fishery integration is a frontier industry strongly
supported by the government. Forms of offshore wind power foundation include single pile, jacket, and
floating. Of these, the jacket form itself consists of a large truss structure, equivalent to a large solid cage
frame, which provides the basic conditions for the practical application of wind-fishery integration.
The integrated application of \"offshore wind power\" and \"marine aquaculture equipment\" have great
advantages in terms of space, structure and function. It not only broadens the application scenario of the
sea, makes full use of marine resources, and maximizes economic benefits, but also effectively reduces
overall costs, guiding the development of offshore wind power towards deep sea development while
bringing more possibilities for deep-sea aquaculture.
