Sludge dewatering is a critical step in municipal wastewater treatment, as it reduces the volume of sludge, making it easier and more cost-effective to transport and dispose of. Decanter centrifuges have become the preferred technology for sludge dewatering, offering superior performance compared to traditional methods such as filter presses and belt presses.


Our decanter centrifuges use a rotating bowl and screw conveyor to separate water from sludge, delivering dry solids content of up to 35-40%. This significantly reduces sludge volume, cutting transportation and disposal costs by up to 60%. The continuous operation of decanter centrifuges allows for high throughput, making them ideal for large municipal wastewater treatment plants handling millions of gallons of wastewater daily.


Unlike filter presses, which require frequent maintenance and have long cycle times, decanter centrifuges offer low maintenance requirements and continuous operation, reducing downtime and improving operational efficiency. They also handle a wide range of sludge types, from primary sludge to activated sludge, making them versatile and adaptable to changing treatment needs. With advanced control systems, operators can easily adjust process parameters to optimize dewatering efficiency and ensure consistent results.


Membrane separation technology is a kind of technology that uses a selectively permeable membrane as the separation medium. By applying a certain driving force (such as pressure difference, concentration difference, etc.) on both sides of the membrane, the components on the feed side can selectively permeate through the membrane, so as to achieve the purposes of separation, purification, concentration and so on.
Nowadays, more and more enterprises have keenly perceived the remarkable advantages brought by membrane technology and are actively adopting this technology to boost their own development.

In the food and beverage industry, enterprises utilize membrane technology for operations such as juice concentration and protein purification. This not only effectively preserves the flavor and nutritional components of products but also enhances product quality and extends the shelf life.

In the chemical industry, membrane technology can be applied to the recovery and separation of solvents. It improves the utilization rate of raw materials, reduces production costs, and at the same time, decreases pollutant emissions, enabling green production.

In the water treatment industry, membrane technology plays an irreplaceable role. From the in-depth treatment of industrial wastewater to the purification of drinking water, by removing impurities, heavy metal ions, and microorganisms in water, it provides enterprises with high-quality production water and effluent that meets the standards.

In the biopharmaceutical industry, membrane separation technology can accurately separate and purify biological products, ensuring the activity and purity of products and facilitating the smooth progress of new drug research and development as well as production.

It can be said that membrane technology is gradually becoming an important means for enterprises to enhance their competitiveness and achieve sustainable development.
