Nanofiltration Softening System 18,000 GPD - Mexico

Product Description

A Nanofiltration Softening System was manufactured and supplied  to Colgate Palmolive in Mexico with a flow rate at 18,000 GPD.

Nanofiltration systems are used for the removal contaminants from water sources, and are commonly used for reducing big ions. Nanofiltration (NF) is a cross-flow filtration technology that falls between ultrafiltration (UF) and reverse osmosis (RO). The membrane has about a 1 nanometre nominal pore size. Nano filter membranes are usually rated by molecular weight cut-off (MWCO) instead of nominal pore size. The molecular weight cut-off is usually less than 1000 atomic mass units (daltons). The pressure drop across the membrane (transmembrane pressure) required is lower than the one used for a reverse osmosis system leading to a significant reduction in operating cost. Nano filter membranes are still faced with scaling and fouling, therefore, antiscalants are highly recommended for use. Nanofiltration (NF membrane) functions similarly to reverse osmosis or RO membrane, but is generally targeted to remove only divalent and larger ions. Monovalent ions such as sodium and chloride will pass through an NF or Nano filtration membrane, therefore many of its uses involve de-salting of the process stream. In the production of lactose from cheese whey, for example, NF Filtration System concentrates lactose molecules while passing out salts, a procedure that purifies and concentrates the lactose stream. In water treatment, NF membranes are used as a softening membranes for hardness removal (in place of water softeners), pesticide elimination, and color reduction. It can also be used to reclaim spent Sodium Hydroxide NaOH solutions, in which case the permeate stream is purified NaOH, allowing reuse many times over.

Nano Filtration System for Radium Removal Mexico 18,000 GPD | www.pureaqua.com 01:56

Radium can be removed from potable water to compliant levels using any of several methods. Nanofiltration (NF), in water treatment, “bridges” a gap between UF and RO membranes. It is sometimes referred to as a loose or lower rejecting RO membrane. It could also be called a tight UF, as NF membrane pore size ranges from .01 to a little less than .001. Generally, an NF membrane system lets more salt pass than an RO membrane. In addition, an NF membrane element will produce the same quantity of product at 50 to 70% the applied pressure as an RO water treatment system.
