POTABLE WATER TREATMENT SYSTEMS
water systems for clean drinking water from 10 to 200 gallons per minute
are easily skid mounted and rapidly installed in the field. Remco Engineering systems are always PLC controlled to
ensure a minimal level of operator involvement in the operation of the
FLOW MUNICIPAL SYSTEMS.
systems at 500,000 gallons per day and above are usually designed to
clarify with a polymer and coagulant to remove solids and the solids are
precipitated in a large settling tank. High hardness waters are limed to
remove excess hardness. These can be automated and are sometimes modular in
construction. Higher flow systems are usually built in place due to the
size required for the settling ponds.

GPM SKID MOUNTED POTABLE WATER SYSTEMS - Low dissolved solids
Remco Engineering skid
mounted systems are designed to run automatically and unattended except for
periodic maintenance. We us computer controls (PLC) to monitor all function
so we can take most of the human monitoring out of the system. The basic
systems include the following -
Prefiltration - Using either backwashable media filters, and or cartridge filters,
depending on the size of the system, the solids are removed to a 5 micron
tank - For filtered water potable water -
pumps - High pressure pumps for supplying potable water
- For destruction of bacteria, viruses, and cysts. Chlorination is the most
reliable, persistent sterilization agent. Other choices such as ultraviolet
light or ozone are available depending on the water source.
monitor - For insuring proper chlorination level
tank and metering pump - adds the correct amount of chlorine to the system
tank - Allows the system to turn off the pumps if now water is required and
still hold pressure on the line.
controls - Including flow meters, pressure sensor and gauges, level
controls, and pressure switch, all monitored by the PLC to provide complete
control and safety. Our systems can be monitored remotely over the internet
if it is available.
DISSOLVED SOLIDS SYSTEMS - over 700 ppm total
are usually custom and use reverse osmosis to
remove excess solids. Extensive treatment including softening, carbon, chlorination/dechlorination
may be required depending on the water source.
SAND FILTRATION (SSF)
small villages, the lowest cost potable water system is probably a slow
sand filter. It is simple to operate and, if the feed is fairly clean, low
maintenance. They take a lot of land area and require manual maintenance to
remove the filtered material. The two links below will give you a start in
learning about SSF systems
