Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. With years of expertise in the water treatment industry, we proudly present our Membrane Bioreactor (MBR) Zero-Discharge Wastewater Treatment System with a daily capacity of 500 liters. This compact, all-in-one solution is designed to recycle wastewater without any liquid discharge, helping businesses meet strict environmental regulations while reducing water costs. Whether you run a small factory, a commercial building, or a remote facility, this system offers reliable, high-quality effluent that can be reused for irrigation, cleaning, or industrial processes.
The core of our system is the advanced MBR technology, which combines biological treatment with membrane filtration. The result is a treated water quality that consistently meets or exceeds reuse standards. Unlike traditional treatment plants, this unit requires minimal footprint and can be installed swiftly. Our factory, spanning over 10,000 square meters and staffed by more than 200 experienced professionals, ensures strict quality control at every production stage. We have exported to over 20 countries in North America, Europe, Asia, and Africa, earning trust through performance and service.
In the following sections, we will detail the technical specifications, key features, and benefits of the MBR Zero-Discharge system. We also include frequently asked questions to address any concerns you may have.
Product Features & Benefits
- Zero Liquid Discharge (ZLD): The system is designed to achieve complete wastewater reuse. No discharge means no pollution penalties and maximum water savings.
- High-Quality Effluent: The membrane pore size (0.1–0.4 µm) effectively removes suspended solids, bacteria, and viruses. Treated water turbidity typically below 1 NTU.
- Compact & Skid-Mounted: The integrated design includes biological tank, membrane module, aeration system, and control panel on a single skid. Requires only 2.4 m² floor space.
- Automated Operation: Programmable Logic Controller (PLC) with touch screen allows for unattended operation. Real-time monitoring of flow, pressure, and water quality.
- Low Sludge Production: MBR operates at high mixed liquor suspended solids (MLSS) of 8,000–12,000 mg/L, reducing sludge disposal frequency and cost.
- Energy Efficiency: Optimized aeration and membrane scouring reduce power consumption. Typical energy usage is 0.6–0.8 kWh/m³ of treated water.
- Flexibility & Customization: Optional pre-treatment (e.g., grease trap, screen) and post-treatment (UV disinfection, remineralization) available.
- Durability & Long Membrane Life: Membranes are made of reinforced PVDF with typical lifespan of 3–5 years. Replacements are cost-effective and easy.

Frequently Asked Questions
-
Q1: What type of wastewater can this system treat?
This MBR system is suitable for domestic sewage, kitchen wastewater, commercial gray water, and certain industrial effluents (e.g., food processing, light manufacturing) with COD up to 500 mg/L. For high-strength waste, pre-treatment may be required. -
Q2: How often does the membrane need to be cleaned?
Membrane cleaning depends on influent quality. Generally, a maintenance wash (chemical cleaning) is performed every 1–3 weeks. A more thorough recovery cleaning is recommended every 6–12 months. The PLC alerts when the transmembrane pressure increases. -
Q3: What is the typical membrane lifespan?
Under normal operating conditions, the PVDF membrane can last 3–5 years. Proper maintenance and avoiding abrasive solids will prolong its life. -
Q4: Is the system ready to use out of the box?
Yes, the system is fully assembled on a skid. On-site requirements include a level concrete pad, electrical connection, and influent/effluent piping. We provide a detailed installation manual and remote support. -
Q5: Can the system run 24 hours a day?
The system is designed for intermittent operation (e.g., 8–12 hours per day) to match the 500 L/day capacity. If continuous inflow is needed, we recommend a larger model or an equalization tank. -
Q6: What is the power consumption and voltage requirement?
Typical power consumption is around 0.4 kWh per day (running 8 hours). The standard voltage is 220V single phase or 380V three phase (50/60 Hz). We can customize for your local supply. -
Q7: Does the system produce sludge? How to handle it?
Yes, some excess sludge is produced, but much less than conventional activated sludge (sludge yield ~0.1 kg/kg BOD removed). Sludge can be discharged periodically and disposed of as usual. -
Q8: Are there any certifications or test reports available?
Our company is ISO9001, ISO14000, and OHSAS18001 certified. The product can be tested upon request. We also provide a performance guarantee report for each unit.
