The Lewabrane RO line consists of spiral-wound, thin film composite membrane elements designed specifically for industrial applications. The membrane chemistry and element construction are designed to provide optimized, low cost of operation for downstream unit operations, like separate- or mixed-bed ion exchange units. The elements comply with NSF/ANSI Standard 61.
Axeon Water Technologies features a range of economical and high-quality membrane chemicals that are specially formulated to treat a variety of feedwater conditions for commercial and industrial applications. The membrane chemicals are compatible with all brands and types of RO, NF and UF membranes. They provide antiscaling and antifouling capabilities to prolong the life of membranes and are certified under ANSI/NSF Standard 60 for drinking water production.
Filmtec RO 75- and 100-gpd home drinking water membranes help remove contaminants and reduce impurities. With a stabilized salt rejection rate of 99% at 75 gpd and 98% at 100 gpd, in standard sizes, the BW-60-1812-75 and TW30-1812-100HR home drinking water elements produce high-quality water quickly. The elements offer a balance of flow and high rejection, producing more water with 20% higher flow rates.
The 3M Pro RO drinking water filtration system uses multistage filtration and includes a high-pressure booster that keeps consistent pressure. It is able to deliver 36 to 50 gal of clean water per day. The system has an electronic pressure switch set to activate at 40 psi and shut off at 60 psi. It is compact and can be installed centrally in a home. With its quick tank recovery, the system is convenient for sinks in kitchens, baths, wet bars and refrigerators.
The NRO Commercial Series of reverse osmosis systems are custom built by Nelsen Corp. to customers’ specifications. NSF-grade high quality parts are used to build these systems. All Nelsen NRO Commercial Systems are wet tested to optimum pressure and production prior to shipment, and they are delivered with individual quality assurance reports to show actual performance data on outputs and rejections.
Membrane processes can be classified in many ways, based on nature, structure or driving force. Hydrostatic pressure differences are used in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO) and gas separation as the driving force for mass transport through the membrane.
Growing range of applications spans the water treatment spectrum
AXEON L1-Series RO systems feature a sleek, compact design that is easy to mount and service. Ranging from 200 to 300 gpd, the L1-Series systems come equipped with fiber-reinforced plastic housings that resist various climate conditions, as well as AXEON Extra Low Energy HF4 Membranes that can provide high production with high rejection and extra-low energy consumption.
AXEON V1-Series RO systems feature a sleek, compact design that is easy to mount and service. Ranging from 500 to 2,000 gpd, the V1-Series systems come equipped with fiber-reinforced plastic housings that resist various climate conditions and AXEON extra-low energy HF4 membranes that can provide high production with high rejection and extra-low energy consumption.
AXEON X2 Industrial Reverse Osmosis Systems are engineered to produce high-quality water by reducing dissolved minerals, bacteria and organic impurities with product water outputs from 50,000 to 1,000,000 gpd. AXEON X2 systems represent an exceptional offering for customers who seek an efficient water treatment solution for drinking water, cooling towers, boiler feed, food processing, bottling, agriculture and a variety of other applications.
Powered only by the hydraulic energy of brine water that is usually lost to the drain, the Permeate Pump—which can be included with Nelsen’s Aqua Elite RO system—forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure. These pumps dramatically improve the efficiency of RO water production, reducing wastewater by up to 80%. They can also bring storage tanks up to line pressure and then shut the system down when the tanks reach capacity, eliminating the need for a hydraulic shut-off valve.
