Pain points of heavy metal wastewater treatment

Heavy metal wastewater contains harmful ions such as lead and mercury, which are highly toxic and easy to accumulate. If discharged
without treatment, it will seriously pollute the environment and threaten health

Pain point analysis

Heavy metal wastewater has a complex composition, and
   traditional treatment is difficult to be efficient and costly.

There are various treatment technologies, but a single technology
   is unable to cope with complex wastewater, making it difficult for
   companies to choose.

As discharge standards are enhanced, corporate compliance
   pressure increases dramatically and risks increase.

The technology is complex and costly, which puts high pressure on
   enterprises and makes it unbearable for small and medium-sized
   enterprises.

Necessity analysis

Effective wastewater treatment is the responsibility of the
   company in environmental protection and is essential to improving
   the environment.

Compliance treatment can improve the competitiveness of the
   enterprise, win trust, and promote the enterprise to obtain policy
   support and financing opportunities.

Advanced technologies ensure compliance with standards, prevent
   pollution accidents, and reduce legal and economic risks.

Responding to the green development strategy, wastewater
   treatment helps enterprises gain policy dividends.

Core Technology for Zero Discharge Treatment of Heavy Metal Wastewater

99.6% of wastewater is reused by adopting the combined process of “pretreatment + OSMMBR + SPNR + MVR"
maximizing the recycling of water resources

Heavy metal high-precision
removal technology
OSMMBR system Special membrane concentration

SC-MVR evaporation crystallization and salt separation technology
Heavy metal high-precision removal technology ensures the complete removal of heavy metals by precisely controlling pH and ORP, adding chemicals, precipitation, filtration, and deep treatment.

Online monitoring and control: Automatic monitoring of pH and ORP, precise dosing.

Efficient stirring system: Fast stirring speed, reaction efficiency increased by 15
times.

Efficient sedimentation control: Corrugated inclined plate filler increases hydraulic
load and prevents plate collapse.

Efficient filtration system: Combine various filter media, 3 times the dirt holding
capacity, and long backwash intervals.

OSMMBR system can treat high-salt wastewater with salt-tolerant bacteria, retain activated sludge, and completely remove suspended solids to ensure that the effluent SS is close to zero.

High volumetric load: Strong adaptability and high-quality output water.

Small land occupation: No secondary sedimentation tank is required, small amount
of sludge.

Efficient treatment: Rremove high-salt and high-difficult-to-degrade COD
wastewater, good denitrification.

Modular design: Easy to expand, moveable, automatic management.

Long-life membrane material: modified PPSU, anti-pollution, easy to clean.

SPNR technology combines crude and refined desalination to concentrate wastewater 20-50 times, and the treated water can be directly reused in production.

It still has high desalination rate at high flow rate.

It has high mechanical strength and service life.

It is able to function at lower operating pressures.

It is less affected by factors such as pH value and temperature.

It has good chemical stability and high cost performance.

SC-MVR technology can achieve zero discharge of high-salt wastewater and salt separation and resource utilization through steam compression, which is energy-saving and efficient.

Efficient heat balance: Optimize heat energy utilization, and reduce the evaporation
cost to 40~50 yuan/ton.

High-precision salt separation: Fractional crystallization to achieve industrial-grade
by-product salt.

Fully automatic monitoring: Video monitoring and data transmission, accurate
prediction and correction.

Stable operation: Multiple technologies are adopted to ensure long-term stable
operation of the system.

Low equipment investment: High-efficiency evaporator and steam partial pressure
technology, reducing costs
