Company Introduces Packaged Ultrafiltration System
Koch Membrane Systems Inc. (KMS), a developer and manufacturer of filtration and separation systems, will introduce its expanded HF series of packaged UF systems at the AWWA Annual Conference & Exposition.
Koch Membrane Systems Inc. (KMS), a developer and manufacturer of filtration and separation systems, will introduce its expanded HF series of packaged UF systems at the AWWA Annual Conference & Exposition. These pre-engineered hollow fiber ultrafiltration systems provide a compact solution, allowing small communities to quickly install potable water production capabilities that meet the requirements of the Safe Drinking Water Act (SDWA).
The packaged UF systems are now available in five models, ranging in capacity from 10,000 to approximately 800,000 gallons per day. These skid mounted, self-contained units are easy to install, given that the only components to be added upon delivery are the membranes. The skid mounted units are space efficient: the smallest model, the HF-4, has a footprint of only 54 square feet, and the largest model, the HF-18, occupies only 200 square feet of floor space. Depending upon the production needs of the customer, the packaged units include anywhere from 4-18 cartridges.
The HF series is designed to help municipalities and private water supplies meet regulatory requirements for surface water treatment. With the proper pretreatment, the packaged systems can be used on a wide range of applications including backwash water recovery, iron and manganese removal, arsenic removal, and color and taste removal. They have been shown to provide drinking water with turbidity levels less than 0.1 NTU and to act as a barrier to virus and microbial contamination.
Koch Membrane Systems’ ultrafiltration is a low pressure membrane technology, producing more consistent and higher quality water than is obtainable with conventional filter media. The small pore size of the UF membranes provides a physical barrier against Giardia lamblia cysts and parasites like Cryptosporidium. A physical barrier means that the membrane structure is such that a properly operated HF system prevents contaminant breakthrough to the product water side, regardless of how long the system is in service and despite any variations in feed water quality.
The pre-packaged systems are designed for simplified operation. All modes of operation are controlled via a programmable logic controller (PLC). Additionally, each system includes all the equipment and instrumentation necessary to operate. Standard components include a painted steel frame, membranes, control cabinet, touch screen panel display, two pumps with variable frequency drive (VFD), and a cleaning tank.
To verify that the system is operating properly a daily membrane integrity test is built into every system. Kochsafe integrity testing can identify one broken fiber out of hundreds of thousands. This short, fully automatic test is designed to verify that system operation is within prescribed guidelines.
Koch’s team of process engineers and service professionals provide technical assistance during installation and start-up. For on-going technical support after installation, the KMS ASSIST® Service and Maintenance Program provides various levels of assistance with plans that can be customized to meet the specific needs of any municipality. Municipalities can select the total service package or simply chose individual service elements as needed. WW
