Innovative Accessories for Bacteria and Virus Removal in Drinking Water and Food/Medicine Separation

Equipment Description:

1. Working principle
‌Separation mechanism‌: With pressure difference as the driving force, macromolecular substances are intercepted through mechanical screening and adsorption on the membrane surface, and water, inorganic salts and small molecular organic substances are allowed to pass through.
‌Filtration mode‌:‌Dead-end filtration‌: Suitable for low turbidity (SS < 5 mg/L) conditions, low energy consumption and recovery rate > 95%.
‌Cross-flow filtration‌: Used for high turbidity or colloid-containing solutions, and reduce membrane pollution by partially discharging concentrated water.

2. Technical parameters
‌Operating conditions‌: Temperature 5-45℃, PH 2-11, upper temperature limit 60℃ (short term).
‌Processing capacity‌: The flux of a single 8-inch membrane module can reach 40 T/H, and the system recovery rate is 85%-95%.
‌Tolerance‌: Oxidation resistance, acid and alkali resistance, can operate for a long time in an environment containing organic solvents or high salt.

3. Application scenarios
‌1. Industrial field‌
‌Electrophoretic coating‌: Recycle electrophoretic paint resin, reduce wastewater discharge and save 30% of coating costs.
‌Water treatment‌: Used for reverse osmosis pretreatment, water reuse and drinking water purification (removal of bacteria, viruses, etc.).
‌2. Food and medicine‌
Separate concentrated proteins, enzyme preparations, remove heat sources and microorganisms.

4. Technical advantages
‌High efficiency‌: No phase change at room temperature, separation accuracy reaches nanometer level, suitable for heat-sensitive substances.
‌Environmental protection‌: No chemical additives, reduce VOC emissions, meet green production requirements.
‌Low energy consumption‌: Energy saving of more than 50% compared with reverse osmosis technology.

5. Operation and maintenance
‌Pretreatment requirements‌: Influent turbidity must be <15 NTU, otherwise sand filtration or multi-media filtration must be added.
‌Cleaning cycle‌: Chemical cleaning once every 1-4 months, acid cleaning (pH2-3) or alkaline cleaning (pH10-11) alternately used.
‌Membrane replacement standard‌: When the flux decreases by more than 30% or the desalination rate is less than 90%, the membrane assembly needs to be replaced.

6. Precautions
‌Parameter monitoring‌: Real-time tracking of transmembrane pressure difference (TMP), a sudden increase in pressure difference indicates membrane contamination or blockage.
‌Membrane protection measures‌: Avoid water containing oil or strong oxidants to prevent degradation of membrane materials.

Main structures and components

1. Pretreatment system
‌Multi-media filter‌: used to intercept impurities such as suspended matter, algae and rust in raw water (particle size > 100μm), and protect subsequent membrane components from being blocked by particles.
‌Activated carbon filter‌: adsorbs residual chlorine, organic matter and some heavy metals to reduce the risk of oxidative damage to membrane materials.
‌Security filter‌: equipped with 5-20μm filter element as the final pretreatment barrier to prevent tiny particles from entering the membrane system.

2. Core separation unit
‌1. Ultrafiltration membrane component‌
‌Membrane material‌: polyethersulfone (PES), polyvinylidene fluoride (PVDF) or polypropylene (PP), etc., with acid and alkali resistance (pH 2-13) and oxidation resistance.
‌Structural form‌:‌Hollow fiber type‌: outer diameter 0.5-2.0mm, inner diameter 0.3-1.4mm, interception is achieved through external pressure or internal pressure design.
‌Roll/tube type‌: suitable for working conditions with high turbidity or high concentration of suspended matter.
Pore size parameters: 0.001-0.1μm, can intercept colloids, bacteria and macromolecular organic matter with molecular weight of 1,000-300,000 Dalton.
2. Pressure drive system
High-pressure pump: Provides 0.2-0.6 MPa operating pressure to drive water flow through the membrane surface to achieve separation.
Pressure sensor: Real-time monitoring of transmembrane pressure difference (TMP), feedback on membrane contamination degree and trigger cleaning procedure.

3. Auxiliary operation device
Backwash device: Use ultrafiltration water or chemical agents for periodic backwashing to restore membrane flux (cleaning frequency 1-4 months).
Chemical cleaning system: Equipped with acid washing (pH2-3) and alkaline washing (pH10-11) circulation pipelines to remove pollutants on the membrane surface.
Automatic control system: Integrated PLC module to realize linkage adjustment of flow, pressure and temperature, and support dead end/cross flow mode switching.

4. Pipes and containers
‌Material selection‌: UPVC, stainless steel or engineering plastic pipes, suitable for different water qualities (such as high salt, organic solvent environment).
‌Liquid storage tank‌: used to temporarily store pre-treated water or chemical cleaning liquid, the capacity is customized according to the system processing volume.

5. Water production and concentrated water treatment
‌Water collection‌: Purified water is output through the water production main pipe for drinking water, industrial reuse and other scenarios.
‌Concentrated water discharge‌: Concentrated water containing retained pollutants is discharged through independent pipes or enters the wastewater treatment system.
Technical features
‌Modular design‌: Each component can be replaced or expanded independently, which is convenient for maintenance and capacity upgrade.
‌Energy consumption optimization‌: Compared with reverse osmosis technology, the operating energy consumption is reduced by more than 50%.
‌Intelligent warning‌: The pump frequency and valve opening are dynamically adjusted through the temperature sensor to ensure the stability of water production.
