Zero-valent nano iron magnetic powder for wastewater/sewage treatment     Hongwu International Group Ltd offer a highly diverse range of powder grades with average grain sizes from approx. 20nm to 150nm. We provide technical support in the selection of the powders suitable for specific applications and for questions regarding process optimization.     Zero-valent nano iron powder have certain magnetic, and under the action of magnetic field can be separated easily and quickly from the wastewater solution, can effectively remove chlorinated hydrocarbon, diphenyl ether, aromatic nitro and polycyclic aromatic hydrocarbons fluorene, etc.  The decontamination mechanism of nano iron: 1. The reduction of nano iron     the iron is active metal with reducing power, thus it can directly reduce dye into amino organic matterin in the partial acid aqueous.Because amino organic color looks light, and easy to be oxidized decomposition, so the chroma of wastewater can be reduced. Some heavy metal ions in the wastewater can be reduced by iron. 2. Micro electrolysis     Iron has electrochemical properties. Its electrode reaction product the new ecological [H] and fe2+ can make the oxidizing reduction with many components in wastewater, dyeing assistant agent can be damaged, broken, loss auxochromic ability; It can make the macromolecular material decompose into small molecule intermediates, and make some difficult biochemical degradation of chemical material become handle easily to improve the water biological properties. 3. The coagulation adsorption     Under the condition of partial acid wastewater it will produce large amounts of Fe2+ and Fe3+, when the PH value to alkaline and aerobic,ferric hydroxide hydrogen and ferrous hydroxide floc form, iron hydroxide hydrolysis could also generate ferrous hydroxide complex ion, which all have very strong flocculation performance, so original suspended solids in the waste water, and insoluble substances produced by micro electrolysis and chromaticity of insoluble substance can be adsorption condensation, hence the wastewater got the purification.     Thus, Zero-valent nano iron powder processing wastewater a comprehensive effect of reduction, micro electrolysis, coagulation adsorption.

 About Nanoparticles & Nanopowders Customization     Hongwu International has a multi-disciplinary team of engineers with backgrounds in chemistry, physics and engineering, and committed to providing quality nanoparticles along with the answers to customer’s questions, concerns and comments. We always looking for ways to better our business and improve our product lines to meet the changing customer demands.   1. Size:     Our main focus is on the nanometer scale powder and particles. We stock a wide range of particle sizes for 10nm to 10um, and can also fabricate additional sizes on demand.   2. Metal alloy nanoparticles:     We can product most metal alloy nanoparticles on the basis of element cu, al, si, zn, ag, ti, ni, co, sn, cr, fe, mg, w, mo, bi, sb, pd, pt, p, se, te, etc. the element ratio is adjustable, and binary and ternary alloy are both available.   3. Surface modification and dispersion:     We can fabricate nanomaterials with specific functional groups especially in carbon family nanoparticles. conversion of hydrophobic nanomaterials to water soluble. we can modify our standard products or develop new nanomaterials to meet your needs.   4. Application:     Ours nanoparticles are being applied by industrial, military and academic laboratories for the development of new products in the areas of electronics, energy generation and storage, fuel cells, optics, biomedical, and life sciences. The applications of our products in the rapid vast expansion of the nanotechnology market is in a state of dynamic evolution.    Contact us to begin discussing how we can develop a nanomaterial for your needs.

Multi-walled carbon nanotube dispersion is a carbon nanotube dispersion that is uniformly dispersed in an aqueous system by means of dispersion to form a liquid with good dispersibility and stability, which is not easy to stratify or precipitate, and is easy to add to application systems.
