Abstract: This project is located in Sichuan and aims to solve the problem of high turbidity and large water quality fluctuations in industrial and municipal wastewater treatment. By deploying advanced ceramic flat membrane ultrafiltration integrated equipment, a stable processing capacity of 400m ³ per day has been achieved. The project successfully treated the incoming water turbidity (up to 100 NTU) to an excellent level of<0.1 NTU in the produced water turbidity, and the operating cost was as low as 0.4-0.5 yuan/ton, providing customers with an efficient and economical solution for sewage treatment and reuse.

2.Project background and requirements

2.1 Industry Pain Points and Challenges

In the fields of municipal water management, industrial wastewater treatment, and circular aquaculture, traditional polymer membranes often face severe challenges. The Sichuan project is designed to address the following typical pain points:
High turbidity and water quality fluctuation impact: The raw water turbidity fluctuates violently between 5-100 NTU, which puts extremely high demands on the anti pollution ability and stability of the membrane system. Traditional organic membranes are prone to clogging under such conditions, leading to frequent chemical cleaning and replacement.
High standard water production demand: Whether used for industrial reuse or circular aquaculture, the produced water is required to have extremely low turbidity and suspended solids to protect subsequent equipment or ensure biological safety.
Operational cost (OPEX) control: In large-scale water treatment scenarios, high energy consumption, chemical fees, and membrane replacement costs are a heavy burden for enterprises. How to achieve extremely low operating costs while ensuring water quality is the core demand of the project.

2.2 Solution: Integrated process of ceramic flat membrane ultrafiltration

In response to the above challenges, we provide an integrated ultrafiltration solution with ceramic flat membrane as the core. Ceramic membranes are an ideal choice for treating complex water quality due to their excellent mechanical strength, chemical stability, and anti pollution ability.
Core equipment selection: The project adopts 6 sets of CFMM-S-54C ceramic flat membrane components, with a total membrane area of 324 square meters.
High strength and long lifespan: Ceramic materials are resistant to acid and alkali, high temperatures, and can withstand high-strength backwashing, with a service life far exceeding that of organic films.
High throughput design: The system is designed to operate at a throughput of 100-200 L/m ² · h, ensuring a large processing capacity of 400m ³/d in a limited space.
Efficient backwashing: The designed backwashing flux can reach up to 250~300 L/m ² · h, effectively removing surface pollutants from the membrane and maintaining long-term stable operation of the system.
Process flow logic:

Pre treatment: The raw water first enters the mixing tank and flocculation tank, where tiny suspended solids and colloids in the water are coagulated into larger flocs by adding chemicals.
Core filtration: The flocculated water enters the ultrafiltration membrane tank, and the ceramic flat membrane, with its uniform microporous structure, efficiently intercepts all flocs, bacteria, and large organic molecules.
Production water storage: Clear production water flows into a clean water tank for reuse or discharge.

3.Project effectiveness and economic benefits

Parameters	Values
Equipment processing scale	370 m³/d
Design operational flux	100~200 L/m²·h
Design backwash flux	250~300 L/m²·h
Design inlet turbidity	5~100 NTU
Turbidity of produced wate	<0.1 NTU

Data interpretation: Even in the face of high turbidity inflow with a maximum impact of 100 NTU, the system can still stably produce high-quality water with turbidity below 0.1 NTU, comparable to bottled water, fully meeting the strictest reuse standards.

Excellent effluent quality:
The turbidity of the produced water remains stable at<0.1 NTU, far exceeding traditional filtration processes, providing excellent assurance for subsequent deep treatment or direct reuse (such as recirculating aquaculture).
Extremely low operating costs:
Thanks to the long service life, efficient backwash recovery ability, and low energy consumption of the ceramic membrane, the comprehensive operating cost of the project has been successfully controlled at 0.4-0.5 yuan/ton. This data is highly advantageous in similar projects, greatly shortening the customer's investment return cycle.
Strong anti pollution and stability:
The inert surface and smooth flow channels of ceramic flat film give it natural resistance to grease, organic matter, and high suspended solids. The system operates stably, has low chemical cleaning frequency, and is easy to maintain.
Compact integrated design:
Integrating coagulation, flocculation, and membrane separation into one, with a small footprint and quick installation, it is very suitable for new construction or renovation projects with limited space
