Containerized MBR System treatment process:

Dosing System (Ni Removing)

For electroplating nickel-containing wastewater and electroless nickel plating wastewater, chemical precipitation can be used for treatment. This method does not require complex equipment. Specifically, for electroplating nickel-containing wastewater, alkali can be directly added to adjust the pH to 11, followed by the addition of PAC (polyalanine chloride) and PAM (polyacrylamide) for coagulation and sedimentation.
Reaction Principle:

Ni²⁺ + 2OH⁻ → Ni(OH)₂ (↓)

Reaction Condition: pH = 10–11

For nickel-containing wastewater with complexing agents, the first step should be to break down the complexes, followed by chemical precipitation.

Dosing System (Cu Removing)

copper is easily oxidized from the +1 valence state to the +2 valence state, although the stability constant of the Cu(CN)₃²⁻ complex ion is relatively large, divalent copper cannot form a stable complex with cyanide ions. Therefore, Cu(CN)₃²⁻ is still readily oxidized, resulting in the conversion of +1 valence copper to +2 valence copper and the oxidation of cyanide. In contrast, Fe(CN)₆⁴⁻ is different. Due to its relatively large stability constant, it is not easily oxidized under conditions of low effective chlorine concentration or low reaction temperature. When the reaction conditions are intensified to oxidize +2 valence iron to +3 valence, since Fe(CN)₆³⁻ remains very stable, the cyanide ions do not dissociate and are not oxidized.

Reaction Principle:
Cu²⁺ + 2OH⁻ → Cu(OH)₂ (↓)
Reaction Condition: pH = 9.5–10.5 

Anaerobic tank which the digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen, There are four key stages of anaerobic digestion involve hydrolysis, acidogenesis, acetogenesis and methanogenesis, and the main function is removed the Nitrogen and bacteria, that will help down the BOD.

Aeration tank, the process involves air or oxygen being introduced into a mixture of screened, and primary treated sewage or industrial wastewater (wastewater) combined with organisms to develop a biological flock which reduces the organic content of the sewage. The main function is removing the nitrifying bacteria and phosphorus bacteria, and break down the COD& BOD

MBR System is separating the clean water from the sewage, membranes to separate solids and liquids, and keep the activated sludge inside of the biological system in higher level that MLSS can be 6000—8000mg/L.  Membrane bioreactor processes can produce effluent of high enough quality for discharge into the oceans, surfaces, brackish bodies, or urban irrigation waterways. Other advantages of membrane bioreactors over conventional processes include reduced footprints and simpler retrofitting.

Clean water tank, for the effluent clean water, it can be use for agriculture application or discharge to environmental.

The Standard components for the mobile containerized MBR System

Applications

• For electroplating nickel-containing wastewater and electroless nickel plating wastewater, chemical precipitation can be used for treatment.

• Surface Metal wastewater or equivalent.

• copper-containing wastewater

The advantages of mobile MBR wastewater plant:

1.  Cost savings,  it’s especially for small capacity project.
2.  Moveable and Less Constructuion works
3.  High Quality, Assembly it according to ISO standard and with quality parts
4.  Fully automatic, easy operation and management
5.  Everything from one source provider
6. Customerized wastewater treatment plant, according to your project requirement.

The Benifits of Containerized MBR Plant:

* System operates at a low pressure
* Removes bacteria and viruses
* Keeps essential minerals in water
* Installs quickly and easily
* Does not generate waste water
* An ultrafiltration system is eco-friendly. Ultrafiltration has a 90-95% recovery rate and can be used to treat wastewater for reuse. Using a home ultrafiltration water system benefits the environment by reducing the amount of plastic water bottles discarded in landfills.
