Core Design Concept

Modular Process Integration

The core design of the system adheres to the concept of "modular combination, targeted treatment". Based on the characteristics of wastewater (such as pollutant type, concentration, and discharge requirements) from different industrial fields, we flexibly integrate and match various treatment processes to form a personalized treatment scheme. Each treatment unit is designed as an independent modular component, which can be quickly assembled, disassembled, and upgraded according to actual needs. This design not only ensures the high efficiency and stability of the treatment process but also improves the flexibility and adaptability of the system, reducing the overall investment and operation costs for customers.

Detailed Introduction of Core Treatment Processes

The Containerized Industrial Wastewater Treatment System integrates six core process modules, which work together to achieve efficient purification of industrial wastewater. Each process module has unique functions and can be flexibly combined according to actual needs.

Dissolved Air Flotation (DAF) with Chemical Dosing System

As the pretreatment unit of the system, the DAF with chemical dosing system is mainly used to remove suspended solids (SS), oils, colloids, and partial organic matter from industrial wastewater, reducing the pollutant load for subsequent deep treatment processes. The system consists of a DAF tank, chemical dosing device, air dissolving tank, and sludge discharge device.

Working principle

Chemicals (coagulants and flocculants) are added to the wastewater through the chemical dosing device to make the suspended solids and colloids in the water aggregate into large flocs. Then the wastewater enters the DAF tank, and the dissolved air water is released into the tank to generate a large number of fine air bubbles. The flocs adhere to the air bubbles and float to the water surface, forming scum which is scraped off by the scum scraper. The treated water flows out from the bottom of the tank. This process has a high removal rate for oils and fine suspended solids, with the SS removal rate reaching over 90% and the oil removal rate over 95%.

Chemical Treatment Process

The chemical treatment process is mainly used to remove heavy metals, refractory organic matter, phosphorus, and other pollutants that are difficult to be removed by physical or biological methods. According to the type of pollutants in the wastewater, different chemical agents are selected for targeted treatment, such as neutralizers, chelating agents, oxidants, and phosphorus removal agents.

Key design

The system is equipped with a multi-stage reaction tank to ensure sufficient reaction time between chemicals and pollutants. The pH value, reaction temperature, and agent dosage are precisely controlled by the intelligent control system to optimize the treatment effect. For example, in the treatment of heavy metal-containing wastewater, chelating agents are added to form stable chelates with heavy metal ions, which are then removed by precipitation and filtration; in the treatment of refractory organic wastewater, oxidants (such as hydrogen peroxide, ozone) are used to oxidize and decompose organic matter into easily degradable small molecules, improving the biodegradability of the wastewater.

MBR (Membrane Bioreactor) Treatment Process

MBR is a combination of membrane separation technology and biological treatment technology, which is used for the biological degradation of organic matter in wastewater. The system integrates a biological reaction tank and a membrane module (hollow fiber microfiltration or ultrafiltration membrane), replacing the secondary sedimentation tank in the traditional activated sludge process.

Advantages

The membrane module can effectively intercept activated sludge and macromolecular organic matter in the reaction tank, increasing the concentration of activated sludge in the tank and improving the efficiency of biological treatment. At the same time, the membrane has a high interception effect on bacteria and viruses, ensuring the quality of the effluent. The MBR process has the characteristics of small footprint, high treatment efficiency, and stable effluent quality, and is suitable for the treatment of organic wastewater with high concentration and complex components, such as food processing and printing and dyeing wastewater.

(Tubular Ultrafiltration Membrane) Treatment Process

Tubular Ultrafiltration Membrane is a high-performance membrane separation technology with a tubular structure. It is specially designed for the treatment of industrial wastewater with high suspended solids (SS) content, high viscosity, and strong pollution, such as wastewater from chemical plants, printing and dyeing factories, and food processing plants.

Key features

The tubular ultrafiltration membrane has high mechanical strength, strong anti-pollution ability, and is easy to clean. Its unique tubular structure allows the wastewater to flow at a high speed in the membrane channel, which can effectively prevent the membrane from being blocked by pollutants. The membrane can intercept macromolecular organic matter, colloids, suspended solids, and bacteria in the wastewater, with an SS removal rate of over 99%. The system is equipped with a backwashing and chemical cleaning device to ensure long-term stable operation of the membrane. The effluent of the tubular ultrafiltration membrane can enter the subsequent NF/RO system for deep treatment or be directly discharged after meeting the standards.

Nanofiltration (NF) + Reverse Osmosis (RO) Filtration Process

As the deep treatment and desalination unit of the system, the NF + RO combined process is used to further remove residual organic matter, salts, heavy metals, and other pollutants from the wastewater treated by the previous process, ensuring that the effluent meets the reuse standard or the strict discharge standard.

Working process

The wastewater first enters the NF membrane system. The NF membrane has a high rejection rate for divalent ions, macromolecular organic matter, and pigments, and can partially remove monovalent ions. Then the effluent of NF enters the RO membrane system. The RO membrane has a high rejection rate for almost all ions and organic matter, realizing desalination and deep purification of the wastewater. The system is equipped with a high-pressure pump, membrane module, chemical cleaning device, and energy recovery device. The energy recovery device can recover the pressure energy of the RO concentrated water, reducing energy consumption. The NF + RO process can make the conductivity of the treated water less than 50 μS/cm, meeting the requirements of industrial reuse (such as circulating cooling water, production water).

Customizable Process Combination Schemes for Different Industrial Fields

Different industrial fields produce wastewater with very different characteristics. Our system can be flexibly combined with the above core processes to provide targeted treatment schemes. The typical process combinations for major industrial fields are as follows:

Chemical Industry Wastewater

Recommended combination: Chemical Pretreatment + Tubular Ultrafiltration Membrane + NF + RO. The chemical pretreatment removes heavy metals and part of refractory organic matter; Tubular Ultrafiltration Membrane intercepts suspended solids and macromolecular organic matter; NF + RO realizes deep purification and desalination, and the treated water can be reused for production.

Food & Beverage Industry Wastewater

The DAF system removes oils and SS; MBR degrades organic matter efficiently, and the effluent can meet the discharge standard or be reused for cleaning.

Characteristics - high content of heavy metals, high turbidity. Recommended combination: Chemical Treatment (Heavy Metal Chelation) + DAF + NF. Chemical treatment chelates heavy metals; DAF removes precipitates and SS; NF further removes residual heavy metals and salts, ensuring the effluent meets the discharge standard.

Chemical oxidation decomposes refractory organic matter; MBR further degrades organic matter; NF + RO realizes deep purification, and the treated water can be reused or discharged up to standard.
