Plant/Process Description:
The East Central Regional Water Reclamation Facility (ECRWRF)
is funded and governed by a board comprised of the representatives of the
entities served by that facility, namely: the City of West Palm Beach, the City
of Lake Worth, the City of Riviera Beach, the Town of Palm Beach, and Palm Beach
County.
Mission: To operate and maintain the East Central Regional Water
Reclamation Facility in a cost effective, reliable, and safe manner, which meets
all State and Federal permits and regulations.
Operations: The ECRWRF is
licensed to function under specific guidelines by the State of Florida and the
U.S. Environmental Protection Agency. The plant is operated by Florida licensed
Wastewater Plant Operators.
Capacity The ECRWRF is currently permitted
to process 55 million gallons of wastewater per day (MGD). That capacity will be
increased to 70 MGD with the completion of an expansion project currently
underway.
Wastewater entering a treatment plant is referred to as the INFLUENT. Influent consists of water, organic materials from toilets and kitchen disposals, and inorganic material such as sediment and industrial chemicals.
BIOLOGICAL OXYGEN DEMAND
(BOD) is a measure of the organic pollution present in wastewater. BOD is the
amount of oxygen needed by bacteria to break down organic material. Influent has
a high BOD because of the levels of organic wastes in the water. Bacteria
utilize this organic material as a source of food. In the process of dissolving
the organic substances, much of the oxygen from the water is consumed. When the
organic material (and the BOD) in the wastewater is removed, the environmental
impact of the effluent is greatly reduced.
Our facility is designed to
remove as much of the waste from the influent as possible so that the treated
water (EFFLUENT) will have minimal impact on the environment when it is
returned.
Influent: Wastewater generated by residential users,
businesses and industry is transported to the Water Reclamation Facility via
underground piping throughout the city and county.
Septage Receiving:
The ECRWRF also operates a septage receiving station at the facility. Septage is
best described as a mixture of sludge, fatty materials, human waste, and
wastewater removed during the pumping of an onsite sewage treatment and disposal
system, such as a septage tank or portable toilets. All septic waste received by
the facility is pumped into the plant Headworks for treatment with the influent
wastewater.
Preliminary Treatment:
Influent enters the facility at the Headworks where it flows through a bar
screen to remove rags, sticks and similar large debris and then though a pair of
grit chambers where sand, gravel and similar materials, collectively referred to
as grit, are removed.
Activated Sludge Process: The ECRWRF uses the
activated sludge process to treat wastewater. This is a treatment in which
wastewater and biological sludge (microorganisms) are mixed and aerated. The
activated sludge process relies on creating a mixture of microorganisms that
consume organic waste material in the wastewater. The biological solids are then
separated from the treated wastewater in clarifiers and returned to the aeration
process as needed.
Influent wastewater flows from the Headworks to the
Aeration Basins where air from high volume blowers is forced into the bottom of
the basin thru ceramic diffusers. The high volumes of forced air creates an
environment where microorganisms thrive by devouring solids and waste. The air
also suspends and mixes the bacteria and organic material so they are more
readily consumed.
Clarifiers: Activated sludge from the aeration basins
flow into the plant's eight clarification tanks. Control manifolds regulate the
flow from the basins into each of the clarifiers.
The Clarifiers serve
to settle the suspended solids in the effluent. This water/solids separation is
performed by gravity. The majority of the bacteria rich solids from the bottom
of the clarifiers are returned to the aeration basin to support and sustain the
growth of microorganisms, with a small portion of the solids being "wasted" to
the aerobic digester. The water in the clarifier tank then flows to the effluent
pump station.
Effluent Pumping & Disposal: The wastewater, now
termed EFFLUENT, is pumped down one of six deep wells for final disposal. The
deeps wells extend into the solid rock layer or Bolder Zone of the earth,
approximately three thousand feet below the surface. Disposal of treated
effluent in this manner is approved by the State of Florida and the
Environmental Protection Agency.
Aerobic Digester: The "wasted" bacteria
from the clarifiers are pumped into the Aerobic Digestion basin. Here the
bacteria sludge is aerated without the addition of a new food (BOD) source,
other than the sludge itself. This causes the bacteria to digest the material in
their own cells, and other dead cells. The result of this digestion is a more
stable material that does not produce nuisance odors, and is more suitable for
dewatering.
Dewatering Operation: Sludge from the Aerobic Digester is
pumped to the Dewatering Building. A polymer solution is added to the liquid
sludge to thicken it prior to processing in the plant's five belt filter
presses. The belt filter presses utilize separate gravity and compression zones
to drain and squeeze the water from the sludge. With careful monitoring and
adjusting, it is possible to produce a sludge cake that is 15 to 18 percent
solid material.
