You will need to circulate a diluted boiler cleaner (HCL acid as the main ingredient) through the system. Check the PH every few minutes and keep adding HCL acid in small amounts to keep the PH at about 6.5. Agitation and/or vibration of the pipes after the first 30 min helps allot. Make sure they sign a waiver.Our main products are dry copper rice machine, wet copper rice machine, high-voltage electrostatic separator and other related supporting machines and equipments. The metal equipment developed by the company has a metal recovery rate of 99.9% for waste wires and cables, which is ahead of the recycling standards of the same industry.

abstract. electroplating waste water containing copper was treated by means of reverse osmosis (ro) membrane separation on a pilot scale. the copper concentration in the untreated waste water was 340 ppm. after the treatment, the concentration in the treated water was below 4 ppm which is the hong kong government discharge limit.A highly flexible simulation program to calculate the resistivity of thin films and lines with various line widths has been developed. The program takes into account the effect of surface and grain boundary scatterings, as well as temperature, on resistivity. At thicknesses approximately equal and smaller than the mean free path, the modeled ...

A new generation of high energy materials depends on the use of Nano-particle oxides. Nano-scale copper oxide (nano-CuO) has large surface area and surface energy which is suitable for its application in the field of energetic materials. …As shown in Fig. 3a, the separation efficiencies of multi-scale CuBTC-coated meshes were all above 99% for different oil/water mixtures. The separation efficiency of calcined copper mesh for n-hexane/water mixture was also measured for comparison. The measured result was 89%, revealing the significant role of our multi-scale CuBTC coating.
