Ceramic Membranes

What is a ceramic membrane?

A ceramic membrane is an inorganic filtration membrane made from materials such as alumina, zirconia or other ceramic compounds. It is used for solid-liquid separation and purification in demanding industrial processes.

Why use ceramic membranes in industrial processes?

Ceramic membranes are valued for chemical stability, temperature resistance and robust performance where process streams are difficult for conventional polymeric membranes.

What applications are suitable for ceramic membrane filtration?

Typical applications include industrial fluid separation, fermentation broth clarification, chemical processing, food and beverage processing, pharmaceutical production and wastewater treatment.

How do ceramic membranes differ from organic membranes?

Ceramic membranes generally offer higher resistance to harsh operating conditions, while organic membranes are often selected for specific concentration, purification and water-treatment duties.

Organic Membranes

What are organic membranes used for?

Organic membranes are used in processes such as concentration, purification, separation, water reuse and selective removal of dissolved substances.

How are organic membrane systems selected?

Selection depends on feed composition, target separation, pressure, temperature, chemical compatibility, recovery targets and required product quality.

Adsorbents

What are adsorbents used for in industrial separation?

Adsorbents selectively capture target ions or compounds from complex liquid streams. They can support resource recovery, purification and separation processes where selectivity is required.

How do lithium adsorbents support salt lake lithium extraction?

Lithium adsorbents selectively capture lithium ions from brine under controlled conditions. The overall process can include pretreatment, adsorption, desorption, purification and lithium-product conversion.

Solid Electrolyte Materials

What are solid electrolyte materials?

Solid electrolyte materials are advanced materials designed to conduct ions in solid-state systems. They are relevant to the development of next-generation energy-storage technologies.

Why are material properties important for solid electrolytes?

Key properties can include ionic conductivity, chemical stability, compatibility with other battery materials, processing characteristics and long-term performance under operating conditions.

New Energy Services

What services are needed for a new-energy separation project?

New-energy projects may require material selection, laboratory verification, process design, equipment integration, commissioning and long-term operating support.

Can Jiuwu support projects beyond material supply?

Jiuwu's technical capability can extend from separation materials and process development to equipment manufacturing, integrated solutions and production services.

Industrial Fluid Separation

What is industrial fluid separation?

Industrial fluid separation uses membrane and integrated process technologies to separate, purify or recover components from liquid process streams.

What information is needed to assess a fluid-separation solution?

Key inputs include flow rate, composition, solids content, temperature, pH, target separation, product-quality requirements and operating constraints.

Water Treatment & Resource Utilization

How can membrane technology support industrial water treatment?

Membrane processes can improve solid-liquid separation, enable water reuse, reduce discharge volume and support recovery of useful resources from complex industrial streams.

What is zero liquid discharge?

Zero liquid discharge, or ZLD, is an integrated treatment approach that maximizes water recovery and minimizes liquid waste discharge, often using membrane concentration and further thermal or crystallization steps.

Industrial Waste Acid Resource Utilization

What is industrial waste acid resource utilization?

It refers to process routes that separate and recover reusable acid or other valuable components from industrial waste-acid streams, reducing disposal demand and improving resource utilization.

How is a waste-acid recovery route evaluated?

Evaluation considers acid concentration, impurity profile, flow variability, corrosion risks, recovery targets, utility requirements, downstream use and environmental compliance.
