UV-AOP ADVANCE OXIDATION

Under appropriate wavelengths of light, hydrogen peroxide undergoes photolysis into highly reactive hydroxyl radicals, which rapidly react with 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.
Applicable to wastewater with high COD, wastewater with high toxicity, wastewater with high chromatically, and other hazardous wastewater.

CRYSTAL SEED SOFTERNING TECHNOLOGY

The structure of calcium sulphate seed crystal is the same as the scale, the crystal surface has a large affinity for scale, so the precipitated calcium sulphate molecules in the concentrated solution will be continuously enriched to form precipitates under the action of water

EcoN&P DENITRIFICATION PROCESS

The EcoN&P system effectively integrates layered materials to promote microbial growth and facilitate efficient denitrification. This approach is both cost-effective and environmentally friendly, while the addition of thiosulfate accelerates the process and ensures optimal performance in cooler conditions. Together, these components offer a powerful solution for removing nitrate and phosphorus from wastewater.

Utilizing a Structured Mesh:
Our patented PVDC mesh increases the surface area available for bacterial growth, essential for effective wastewater treatment.

Encouraging Bacterial Biofilm Formation:
Thiobacillus and Sulfurovum bacteria form biofilms that break down pollutants, enhancing treatment efficiency.

Minimizing Sludge Production:
This biofilm approach results in lower sludge generation compared to traditional methods, streamlining treatment processes.

Boosting Denitrification with Thiosulfate:
Thiosulfate supplementation improves the denitrification process, especially at lower temperatures.

Integrating with ANAMMOX for Enhanced Efficiency:
The EcoN&P system, when combined with the ANAMMOX process, elevates nitrogen removal rates to as much as 92-95%, making it highly effective in wastewater management.

ELECTRO-CATALYTIC OXIDATION REDUCTION

When the electrode coated with special noble metals is electrified, electro-catalytic oxidation (ECO) and electro-catalytic reduction (ECR) are carried out simultaneously, so that persistent organic pollutants can be effectively degraded and mineralized.
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-colouration capabilities, and the produced water is colourless and transparent.
For water with high nitrate content, ECR with special electrode can reduce it.
It is suitable for high salinity wastewater. The strong chlorine separation ability products a large amount of hypochlorous acid in the system, making it very effective for ammonia nitrogen removal.

LANDFILL LEACHATE TREATMENT TECHNOLOGY

Landfill leachate is highly polluted wastewater that threatens water resources, exhibiting fluctuations in volume and quality, high pollutant levels, non-biodegradable substances, and nutrient imbalances.

Quality varies with age: the acid phase has a high BOD5 (around 10,000 mg/L) and is suitable for biological treatment, while the methanogenic phase presents challenges due to declining BOD and increased ammonia. Single biological treatments often cannot meet discharge standards, necessitating reverse osmosis technologies, with high-rejection DTRO/STRO membranes effectively removing contaminants.

Containerized leachate treatment systems from Germany offer quick start-up, minimal space requirements, and lower costs while efficiently removing salts and emerging compounds, with flexibility for optional pre-filtration or post-evaporation.
