Specialty Separation Membrane OLAND High-efficiency Denitrification Technology Process Package CRYSTAL Seed Crystal Softening Technology UV-AOP Advanced Oxidation SOLID Solidification Technology SEVAP (Anti-scaling and Energy-saving Type) Evaporator ECOR Electro-Catalytic Oxidation-Reduction |
Specialty Separation Membrane
Product features：
According to the characteristics of high salt organic sewage, the company independently developed high-performance membrane components with unique open runner design. When the fluid passes through the filter membrane surface, turbulence can be formed, which reduces the deposition of pollutants on the membrane surface and thus reduces concentration polarization. The open flow channel enables the membrane module to have a certain self-cleaning function, which can effectively solve the problem of membrane scaling, reduce the operating pressure and operating cost, and extend the service life of the membrane.
Significant advantages：
Resistant to salt and organic matter;
Strong resistance to high pressure;
Can effectively resist the corrosion of organic and inorganic pollutants and salts;
Long service life, good stability;
The problems of wastewater treatment and resource utilization in the field of high difficulty and high barrier which are difficult to be solved by ordinary membrane technology are solved.
OLAND High-efficiency Denitrification Technology Process Package

High organic load, high processing efficiency, can effectively remove COD,nitrogen,phosphorus,etc.
Highly integrated, small footprint, easy to install, and easy to achieveautomatic control.
No additional deodorization treatment device is required, and odour canbe effectively removed.
Less air supply is required, low power consumption and running cost.Low carbon-nitrogen ratio requirement, the minimum operation condition:B0D/TN=2.5.
Resistance to acid, alkali and salt contents.
The system can achieve stable operation at low temperature.
Application Scope：
Applicable to newly-built municipal wastewater treatment facilities.standard upgrading and retrofit without stopping production.It is suitable for wastewater with high organic, high nitrogen and highsalinity contents.
CRYSTAL Seed Crystal Softening Technology
Performance Advantages:
The structure of calcium sulphate seed crystal is the same as the scale.the crystal surface has a large affinity for the scale, so the precipitatedcalcium sulfate molecules in the concentrated solution will be attachedto the suspended crystal seed preferentially, and will be continuouslyenriched to form precipitates under the action of water, and.
The calcium sulfate and magnesium sulfate molecules in theconcentrated solution will be deposited on the seed crystal preferentiallyto remove the scale and eliminate scaling.
High load and large flow rate.
The removal rate of Ca2+ in water is up to 90%, and the effluent isstable.
Application Scope:
Applicable to RO/NF concentrated brine.
UV-AOP Advanced Oxidation
Performance Advantages:
Under appropriate wavelengths of light, hydrogen peroxide undergoes photolysis into highly reactive hydroxyl radicals, which rapidly reactwith organic and inorganic substances in water, producing inorganic
byproducts such as water and sulfates.
It efficiently decomposes organics under standard temperature and pressure, facilitating the mineralization breakdown of pollutants, with no selective preference for specific organic contaminants.
It exhibits high oxidation efficiency, operates automatically, allowing unmanned operation without generating secondary pollutants.
The reaction conditions are mild, with strong oxidative power, effectively breaking down organic matter into CO2, resulting in high treatment depth.
Application Scope:
Applicable to wastewater with high COD, wastewater with high toxicity, wastewater with high chromaticity, and other hazardous wastewater.
SOLID Solidification Technology
Performance Advantages:
The mother liquor of the evaporator leachate is high in salts, organics and heavy metal content. Chelating agent is used to prevent leaching of heavy metals, and then thickened by thickener to bind its pollutants,
and finally stabilized in the solidified matter；
The solidified material meets the standard of Table 1 of the "Pollution Control Standard for Domestic Waste Landfills" (GB16889-2008)；
After the evaporation mother liquor is solidified, it is easy to transport, store and dispose.
Application Scope:
Suitable for SEVAP high-efficiency and energy-saving evaporator leachate mother liquor.
SEVAP (Anti-scaling and Energy-saving Type) Evaporator
Product Description:
Innovative online energy-saving anti-scaling system.
Including compressor system, cleaning system, dosing system, onlineanti-scaling system,electric heating steam system, PLC control systemand washing system.
Performance Advantages:
For wastewater with high organic matter, fouling and scaling problems,no need to stop for frequent cleaning, which greatly improves theproduction efficiency and reduces energy consumption.
Treatment capacity: 300-400 tons/day.
Recoveryrate of DTRO concentrate: 80-90%
Total Recovery rate: 90-95%.
ECOR Electro-Catalytic Oxidation-Reduction
Product Description:
The system does not need chemicals, does not generate sludge, and can achieve complete discharge without concentrate.；
The equipment has small footprint；
It has strong de-coloration capabilities, and the produced water is colorless and transparent；
For water with high nitrate nitrogen content, ECR with special electrode can reduce it.
Application Scope：
It is suitable for high salinity wastewater. The strong chlorine separation ability produces a large amount of hypochlorous acid in the system, making it very effective for ammonia nitrogen removal.

A high-tech enterprise that focuses on independently developed special separation membrane technology and provides customers with professional modular solutions.
Modular design allows for flexible assembly and combination
Low energy consumption and low cost
The use of electrocatalytic technology does not produce salt sludge
Stable production water quality
The company's fully quantified treatment system for leachate includes DTRO reduction module, seed softening module, STNF special material separation technology, electrocatalytic oxidation-reduction module, high-efficiency evaporation SEVAP module, and mother liquor solidification evaporation module. The company can flexibly combine different modules based on the actual water quality of the project
Due to the effective removal of organic matter, ammonia nitrogen, total nitrogen, and heavy metals from DTRO concentrate using electrocatalytic oxidation-reduction technology, there is no production of mother liquor or salt sludge
Due to the low COD content in the water produced by the STNF material separation membrane, the problem of high power consumption in the electrocatalytic system can be significantly reduced. In addition, the SEVAP high-efficiency and energy-saving evaporator with online descaling technology and special steam operation mode as the core improves the treatment efficiency of concentrated liquid and reduces energy consumption in the treatment process
The produced water meets the standards in Table 2 and Table 3 of the Pollution Control Standards for Domestic Garbage Landfills (GB16889-2008); The waste residue meets the landfill entry requirements specified in the Pollution Control Standards for Municipal Solid Waste Landfill Sites (GB16889-2008) and the limit values for pollutant leachate in Table 1
