Ryan Process can supply you with a wide range of filtration systems for industrial, and municipal wastewater, water and groundwater.

The most popular and efficient filtration systems for the removal of large quantities of particulate material from water are media filters. They remove debris, algae, sand, and silt from large volumes of water at low pressure loss. Service is minimal for there are no moving parts. Backflushing is a quick and efficient method of cleaning.

Vertical Tank - Symmetrical distribution of incoming raw water at all flow rates, as well as concentric concentration of backwash water. High strength butt welded carbon steel tank with interior coating of bitumastic coal tar, a material proven for its heavy duty corrosion resistance and ease of maintenance.

Stainless Steel Underdrain - The high strength profile wire screen retains medias finer than No. 20 silica sand thus eliminating the need for filter back up screens. The strategic placement of these screens give a uniform backwash and eliminates raw water short circuits. The non-clogging characteristic of the screen makes it the most field serviceable and rugged media filter available.

Backwash Valve - Heavy duty high strength Epoxy Coated ductile iron, a material known for its resistance to corrosion. Non slamming design. All wetted surfaces stainless steel or Epoxy Coated. Field serviceable.

Automatic Backwash Control - Everfilt designs and manufactures its own automatic backwash controls. User friendly control knobs, panel labeling and display lights make for easy use. Made of solid state electronic circuits, the automatic controls help assure effective system operation by initiating needed backwash in an efficient manner. The control can be set to trigger backwash either when a specified pressure differential or time interval is reached. The control is housed in a UL-listed, NEMA 4 water resistant enclosure.
The LCD display indicates when the next backwash cycle is timed to begin, the total number of backwash cycles that have been initiated since last reset, and the number of backwashes that have been triggered by pressure differential. Users find this information very useful in identifying operating conditions requiring their attention.
Models are available for 4, 8, and 12 station controls. Thus, in some cases it's possible to expand an existing filter installation without the expense of changing controls.

Solar Power - For field conditions where electric power is unavailable or unreliable, or where it is just more cost-effective, Everfilt offers a 12 volt DC solar power option. The heavy duty battery has the capacity to deliver power to the system even in overcast weather.
