POTABLE
WATER TREATMENT SYSTEMS
Potable
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 system.
Types
of systems - 
HIGH FLOW
MUNICIPAL SYSTEMS.
These
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 level.
Holding
tank - For filtered water potable water -
Feed
pumps - High pressure pumps for supplying potable water
Chlorination
- 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.
Chlorine
monitor - For insuring proper chlorination level
Chlorine
tank and metering pump - adds the correct amount of chlorine
to the system
Bladder
tank - Allows the system to turn off the pumps if now water
is required and still hold pressure on the line.
System
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.
HIGH DISSOLVED
SOLIDS SYSTEMS - over 700 ppm total dissolved solids.
These
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.
SLOW SAND
FILTRATION (SSF)
For 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
