RisingSun Membrane Technology (Beijing) Co., Ltd. products

Leachate from landfills and incinerators arises mainly because rainwater penetrates the stored waste, but also from leakage of the garbage. The polluted leachate is collected by the garbage dump and undergoes special wastewater treatment. The wastewater from landfills is characterized by a high variety of waste. RisingSun Membrane offers a kind of PVDF 30nm tubular membrane for the leachate industry. See below for the related membrane products for the landfill industry.

Tubular membranes are particularly suited to liquid with high viscosity or suspended solids, because their wide flow paths make them highly resistant to clogging. Tubular membranes system is an external and separated filtration system. For high solid content and viscosity liquid, we use adjustable cross-flow velocity to make the membrane run under optimal conditions and extend membrane service life. At the same time, it has more convenient cleaning, maintenance, and operation under closed pipeline.

UF membranes are characterized by their molecular weight cut-off between 1000-200,000 Dalton usually. Ultrafiltration is a pressure-driven membrane process being capable of separating solution components on the basis of molecular size and shape. Under an applied pressure difference across an ultrafiltration membrane, solvent and small solute species pass through the membrane and are collected as permeate while larger solute species are retained by the membrane and recovered as a concentrated retentate.

NF membrane has a molecular weight cut-off between 200-800 Dalton usually. It is generally targeted to remove only divalent and larger ions. Monovalent ions such as sodium and chloride will pass through a nanofiltration membrane, therefore many of its uses involve groundwater softening, de-salting of the process stream. NF membrane is also becoming more widely used in food processing applications such as dairy, for simultaneous concentration and partial (monovalent ion) demineralisation. NF membrane operation press is around 3.5-30 bar.

RisingSun tubular Anode/Cathode cell can be used in E-COAT paint system with most types of paints. It serves as the opposing electrode and simultaneously removes solubilizer (usually a common organic acid) from the paint to maintain chemical balance. We use American outstanding quality ion exchange membrane with low resistance, high permselectivity.
