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.

Testing Packages Aid in RO System Design

Publication Date:

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.


Environmental World Products focuses on component distribution, sourcing and new product development for commercial and industrial water treatment applications. Its product line includes RO system components, such as membrane housings, filter housings, bag housings, filter cartridges, couplings, control valves, flowmeters, solenoid valves, needle valves, controllers/monitors and pressure gauges.


Test Package

The Complete RO Screen was developed with input from membrane manufacturers and treatment professionals. This package tests for most factors that can reduce the life of an RO membrane. Due to the nature of RO produced water, the testing was designed to provide lower detection levels. This test package is also beneficial for other applications that require pure water. New and improved compact packaging will reduce shipping costs.


Industrial RO Systems

Company Reference: 

SWI industrial-sized seawater RO systems have capacities ranging from 8,000 to 500,000 gpd. They feature duplex stainless steel multistage high-pressure pumps, FRP membrane housings, 8-in. TFC membranes, a non-corrosive prefilter and an advanced PLC-based control panel with touch screen, all mounted on a powder-coated steel frame that supports all instruments, piping and valves. Custom-made systems are available.

Particle Characteristic Advantages in Adsorption Technology

A wide range of research and development is being conducted to solve the challenges of providing clean water, with a significant emphasis on drinking water. The research focus has included advanced membrane technology; changing water chemistry to suit the remediation technology of choice; and media modification for increased selectivity, activity and capacity.

The purpose of this study is to focus on sorptive media modification for improved performance.
