Processing Penetrant Rinsewater with Membrane Filtration

摘要

Membrane filtration systems have established themselves as the preferred technology for processing a wide range of industrial wastewaters. Thousands of manufacturers are processing spent parts cleaners, machining fluids and other aqueous wastes with membrane systems. Penetrant rinsewaters are an easy waste to process with membranes because they are nothing more than a dilute dye solution. The key to a successful installation is choosing the right membrane and making sure that the operator is properly trained. The nature of dye solutions requires a Nano-filtration membrane to ensure complete color removal without the need for activated carbon or some other post-treatment. The resulting processed water will be colorless and suitable for either discharge or re-use. Care should be taken to make sure anyone operating the system understands the basic way in which the system functions. A regimen should be established to ensure that the residue is emptied after each batch and the membrane is cleaned on a regular basis.
