C. Emery Nelson, Inc represents manufacturers of water treatment equipment including Reverse Osmosis (RO), Filters, Ion Exchange systems – Mixed Bed Deionizers, two bed Deionizers, Softeners, and EDI. These systems are custom engineered to your requirements. For the industrial markets that need purified water, we represent manufacturers that offer a wide range of water treatment equipment. We combine the right water treatment technologies to meet the water quality standards of your industrial process. Some of the most popular systems that our manufacturers design and build are:

  • Demineralization (multi-bed, mixed bed, packed bed, electro-deionization, condensate polishing)
  • Softening; Filtration (multi-media, carbon, greensand, cartridge);
  • Membrane Systems (reverse osmosis, ultrafiltration, nanofiltration, microfiltration);
  • Degasification (forced draft, vacuum, membrane)

We make certain the most economical combination of equipment is provided.

Since the 1940’s, commercial ion exchange resins have been successfully applied to water treatment and other industrial processes. We have decades of experience in ion exchange, and we understand how variables in liquid treatment will affect ion exchange operation and performance. Our industrial experience with a full range of water, wastewater recovery and process systems will help us select the right membrane type and system for your needs the first time.

We offer Standard Reverse Osmosis Systems up to 400 GPM. Pre-engineered for general and industrial applications. Skid mounted, pre-piped and wired for quick installation. Membrane elements factory loaded for immediate start-up.

We also offer electro-deionization for producing Ultrapure water. The EDI unit uses ion-exchange membranes and resins with electric current to remove dissolved salts from water. EDI does not require chemical regeneration, but it is limited to applications where the dissolved salt is small compared to the salt concentration contained in natural water supplies. The typical EDI application treats water that has been partially demineralized by reverse osmosis. Ultrapure water, in excess of 16 Mohm/cm and which has been depleted of ions, flows out of the chamber as a result of this process.

C. Emery Nelson provides turn-key, integrated solutions, tailored to fit the specific needs of each customer. In other words, “We put the pieces together, so you don’t have to.” As a provider of products and systems, we act as an integrator of key technologies in the Process and Industrial markets. We have the resources to utilize a variety of technologies when treating water, process or wastewater issues, allowing us to develop a creative, cost effective solution to fit your needs.
