November 2012

Axeon HF5-Series membranes are the industry's only ultra-low-energy commercial membranes featuring a low nominal operating pressure of 80 psi. They offer production rates up to 2,500 gpd with 98.5% salt rejection for improved system performance. The membranes offer a wider range in pressure to compensate from the loss of flow from cold water temperatures. In addition, they are ideal for tap and brackish water applications and offer higher efficiency levels, thus reducing energy costs by up to 23%. All of Axeon's membranes are manufactured in the U.S.

This point-of-use, five-stage ultrafiltration (UF) system for residential applications produces cold filtered water with less water waste and lower operational costs compared to typical reverse osmosis systems. The UF system eliminates viruses, bacteria, benzene, chlorine, Cryptosporidium, pesticides and rust. It also reduces algae, chloride, copper, lead and mercury, and leaves healthy minerals in the water.
 

Providing Water Purity

Water purity issues in developing nations and third-world countries populate the news, but pure drinking water can be just as difficult to achieve in developed countries. In the U.S., significant amounts of tap and well water are not fit for drinking due to heavy industrial and environmental pollution that result in water contamination. Even low-level exposure to some contaminants can cause illness, including liver damage, cancer and other serious ailments.

Q-SEP hollow-fiber ultrafiltration membranes feature a patented cloud point precipitation process; high-strength hollow-fiber membranes; uniform pore size distribution for consistent water quality; improved filtrate quality; low and consistent SDI; and high bacteria and virus rejection. The membranes are NSF/ANSI Standard 61 certified.

Membrane Antiscalants Maintain RO Output and Efficiency

Publication Date: 
July 9, 2012

In any membrane filtration system, scaling is inevitable. There are many forms of scale, some of the most common being calcium carbonate, calcium sulfate, barium sulfate and strontium sulfate. Left unmanaged, crystal scale will accumulate and become a mass of crystals on the surface of the membrane, causing blockage. This is harmful to reverse osmosis (RO) systems because it increases operating pressure. High pressure can put stress on the system and reduce product output and efficiency levels. A severely scaled membrane easily can reduce its gallon output by more than half.

When considering reverse osmosis (RO) for water treatment, there are several things that should be taken into account. One of the most important things to consider is the quality of the water to be treated. RO is widely used to remove harmful inorganic contaminants; however, due to the limitations and higher operating cost, pretreatment of the water may be necessary. For example, hardness minerals are common in groundwater, and at high levels, pretreating with a softener is often recommended.
