Model HF4 Series - Reverse Osmosis Units
From Reverse Osmosis
The HF4 are available in configurations ranging from 2,200 to 43,200 gpd. Standard features include onemicron ROsave.Zs prefilter, automatic inlet shut-off valve, permeate and concentrate flow meters, remote machine on/off capability, thermal motor protection, pre-filter, post-filter, primary & final pressure gauges, and flow control center including concentrate/ recycle valves. Deluxe Features in addition to the standard include auto flush system, low inlet pressure switch, digital conductivity meter with programmable relay, and alarms: low inlet pressure, motor starter overload.

The separation of suspended and dissolved impurities, including ions, from a solution through the application of pressure on a special semi-permeable membrane element. The removal of ionic, organic and suspended / dissolved impurities is accomplished during the RO process. Unlike a filter, which separates by conventional filtration, the RO membrane element separates using a process called cross-flow filtration. Feed water is separated into two streams - permeate and concentrate - and collected from both sides of the membrane element.

The inherent advantages of Membrane technology can be summed up as follows:
- RO units produce water similar in quality to demineralized or distilled water.
- Low operating costs as well as the ability to remove organic contaminants and 95-99% of inorganic salts make RO an attractive and ideal water purification technology for most industrial applications.
- Nanofiltration has a larger membrane pore structure, which allows more salt passage through the membrane. Because it can operate at much lower pressures, and passes some of the inorganic salts, NF is used in applications where high organic removal and moderate inorganic removal are desired. An advantage of NF over RO is that NF can typically operate at higher recoveries, thereby conserving total water usage due to a lower concentrate stream flow rate.
Pre-Filter
RO pretreatment is critical to extracting the longest life out of the RO membrane elements by removing RO membrane-plugging contaminants from source water. Effective pretreatment minimizes wear-and-tear on your RO elements by reducing the Silt Density Index (SDI) to recommended levels.
Self Contained
Our state-of-the-art Reverse Osmosis systems are compact and self contained, thus saving our customers valuable space as well as enabling freer access to the unit during installation, service or maintenance.
(PLC) Real-Time Monitoring Control Panel
Designed around the Allen-Bradley SLC 503 series system, with integrated touch screen, control and real time monitoring, system navigation is a breeze and all programming changes and process parameters remotely.
