We employ advanced membrane technology to provide highly selective, energy efficient and cost-effective separation solutions to major industrial sectors across the globe.
Solecta designs, produces and sells membranes and elements capable of consistently separating molecules according to chemical properties or size, while substantially reducing energy consumption and overall separation cost. Our focus is to reliably deliver robust, highly stable membrane-based solutions with predictable selectivity and productivity attributes needed to support high volume production processes. We offer polymeric-based microfiltration, ultrafiltration, nanofiltration and reverse osmosis products tailored to the specific needs of our customers.
Polymeric membranes, also known as organic membranes, encompass a family of liquid separation technologies that is industry leading in both performance and efficiency. These membranes are generally identified in four major categories, based on performance characteristics and specific separation attributes. In order of the coarsest separation to the finest, they are: microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The polymers utilized in the production of each membrane category are carefully selected in order to ensure optimal performance in a chosen process environment. Compatibility with the fluid(s) to be processed, as well as with cleaning agents necessary to aid in hygienic and performance stability must be taken into consideration. The scope of polymers may include polyvinylidene fluoride (PVDF), polysulfone/polyethersulfone (PS/PES), polypiperazine and polyamide.
Microfiltration (MF) refers to a category of membranes where separation range (pore size) is expressed in micrometers (µm), and is typically considered to be about 0.1 µm and greater.
Ultrafiltration (UF) refers to a family of membranes where separation range (pore size or molecular weight cut-off (MWCO)) is expressed in Daltons (Da) or kilo-Daltons (kD), and is typically considered to be in a range of 1,000 Da (1kD) to 100,000 Da (100kD).
Nanofiltration (NF) refers to a category of membranes where separation range is categorized based on rejection characteristics of known solutes such as magnesium sulfate (MgSO4) and sodium chloride (NaCl).
Reverse Osmosis (RO) refers to a variety of membranes where separation range is categorized based on rejection characteristics of a known solute, traditionally sodium chloride (NaCl).
