UF ultrafiltration technology provides a highly effective treatment solution in tertiary wastewater reuse, process water, and drinking water applications. These applications, are geared toward treating tertiary wastewater, surface water, and grey water sources containing a variety of organic, inorganic particulates and microbiological contaminants. GWT UF utrafiltration systems offers the ability to reduce and remove particles as small as 0.01 micron, therefore, they can provide treated water that has virtually no suspended solids that is free of microbial contamination.

Ultrafiltration systems operate using a semipermeable membrane to separate suspended solids from water. The membrane has pores of a certain size that allow water, ions, and molecules of low molecular weight to pass through, but larger particles are retained on the feed water side. The water will not flow through the membrane on its own, therefore, a negative pressure differential is applied across the membrane. The water will move towards the lower pressure side of the membrane.

There are several companies that offer ultrafiltration systems to their clients. We at Genesis Water Technologies, Inc. also offer this advanced water treatment technology with a number of distinct benefits for commercial, industrial clients and municipal utilities looking for solutions for tertiary wastewater reuse, process water treatment, or drinking water needs.

Benefits of GWT UF Ultrafiltration Systems:

• Adaptive system controller

Controls system allow for remote operation of water treatment components. The operation could be manual, requiring a person to interact with the controller regularly to keep the systems moving along. There are also automatic controllers that allow for minimal human interaction to drive the system. However, GWT implements adaptive controls into its ultrafiltration systems. Not only do they operate the system automatically, they can intelligently respond to changes within the system and make operational alterations to compensate. Such control systems allow for precise and timely responses to feed water composition, system pressure, flow rate changes, and other parameters.

• Pretreatment

Membrane systems are sensitive to certain contaminant compounds and concentrations. Fouling can occur frequently, if the system is not carefully monitored and maintained. This fouling problem results in decreased efficiency and increased energy use as well as premature membrane replacement in some cases. These issues can drive up operational costs considerably.

To prevent this, GWT is meticulous about designing and implementing proper pretreatment measures. This includes antiscalants to prevent scaling on the membrane, sediment filtration to reduce suspended solids concentrations that would cause excessive buildup on the membrane, and UV sterilization to prevent bacterial bio-fouling. By minimizing fouling, back washing cycle frequency is also reduced.

• Modular, compact systems

Some clients may not have the space or funds available for a large centralized system. Others may want to replace one of their current treatment systems with ultrafiltration or increase their system flow with minimal footprint, and therefore, will need to retrofit. Regardless of the reason, GWT offers UF ultrafiltration systems that are compact to save space and modular for easy installation.

• Clean-in-place option

There are occasions where just back washing an ultrafiltration system with only water does not effectively clean the membrane surface. Ultrafiltration membranes can also be connected to a cleaning system that uses specific chemicals and higher temperature water to clean the membrane after use. These systems can remove some mineral scale fouling buildups.

• Membrane configuration designed for the specific application

An ultrafiltration system that works for one application may perform poorly in another. Depending on the feed water quality and preferences of the client, there are different system configurations that can fit different needs. GWT UF ultrafiltration systems can be designed for inside-out or outside-in flow as well as submerged or pressure vessel configurations.

In high suspended solid applications like process water treatment, outside-in flow is better able to handle higher solid loads. Inside-out flow works best in low solids concentration applications and has the added benefit of more uniform flow.

Depending on space requirements and whether a client wants easier access to the membranes, submerged or pressure vessel units may be used. A submerged configuration consists of a number of membranes that can be vacuum based, while pressure vessels house individual membranes and are linked together in parallel are typical pressure based.

Whether for tertiary wastewater reuse, process water, or drinking water treatment, a GWT ultrafiltration system is designed to supply our municipal and commercial/industrial clients with quality treated water at optimized capital and operating costs.
