Through proper operation, thelocal ecology of the area will be safe-guarded and the health and welfare of the residents in the area will begreatly protected.

5 This Modular Sewage Treatment Plant has been approved and permitted by the FloridaDepartment of Environmental Protection (FDEP) - Domestic Wastewater Section. When operated properly andmaintained as provided by the manufacturer, the plant is designed by the Engineer of Record , to fit specificrule and permitting requirements. Proper operation of the Sewage Treatment Plant assures the sanitary health andwelfare of the area you serve. This will remain true when properly operated and maintained and as long as theplant is used for the design treatment loading. No other contributing wastewater flows should be introduced intothe plant for treatment, nor should plant modifications be made to it s design and operation without approval andauthorization by the Owner and - PURPOSE & GENERAL :This Operational Guide is intended to describe Sewage Treatment Operation, Plant Start-Up PROCEDURES ,and Operation Testing and Maintenance to enable you to adequately provide sewage treatment for a long periodof time with minimum operation and maintenance INFORMATION:Sewage or waste water is a combination of bodily waste and the domestic waste from park residences,business buildings, institutions, and establishments with ground surface and or storm water as may find its wayinto the Sewage Collecting System.

6 Sewage contents are generally a combination of liquids and solids. Usuallythe solids are less than and are made up of inorganic and organic matter. The solids themselves are alsoclassified as dissolved and suspended solids. Approximately 1/3 of the solids are in a suspended state and theremaining 2/3 are in bacteria types are commonly found in sewage. These include (1) pathogenic, (2) anaerobic, (3)aerobic; pathogenic class of bacteria causes or is capable of causing disease--such as typhoid fever,dysentery, diarrhea, etc. Those bacteria may spread disease and contaminate the area throughunderground and surface water supply bacteria is a microorganism that thrives where oxygen is not available. They performfunctions in the digestion and reduction of bacteria requires free oxygen and is necessary for the nitrification and oxidation processes inthe treatment of is responsible for the decomposition processes; when properly used and controlled, they producethe desired results in the treatment of - SEWAGE TREATMENT PROCESSES, PLANT STAGES & FLOW TREATMENT PROCESSES:In general sewage treatment processes are classified in stages or the degree of treatment afforded.

7 Theprinciple stages or degrees of treatment are: 01/2001 FPSCh. 3 Pg. 5(1)Primary and Preliminary Treatment: Typical unit processes include screening, flow equalization, andprimary settling. When all unit processes are used , this type of treatment removes up to 50% of thesuspended solids and 25 to 35% of the Biochemical Oxygen Demand ( ). (2)Secondary with Clarification: Typical Unit Processes include aeration and settling tankage. Supplementing primary treatment, this aerobic process removes up to 90% of the suspended solids (3)Nutrient Removal: Typical components include an anoxic tank located either in front or in between theaeration tankage for nitrate-nitrogen reduction, and either an anaerobic tank or chemical feed system forphosphorus reduction when required.

8 (4) Filtering (Tertiary) System supplements the first two stages of treatment by removing up to 95% of thesuspended solids and through a physical filtering action. Typical unit processes include filters, filterdosing system, and filter backwashing WEKIWA SPRINGS STATE PARK #2 Sewage Treatment Plant is designed to providesecondary treatment with basic disinfection. STAGES & FLOW SEQUENCE PLANT STAGES:The Modular Sewage Treatment Plant providesthe various stages of sewage treatment. A. Influent Pump Station (located remotelyfrom the WWTF site)B. Aeration Tank C. Final Settling Digester E. Chlorine Contact Pump Station Disposal System (Sprayfield)SECTION - SETTINGS & OPERATION & OPERATION OFEQUIPMENTThe proper setting and operation of equipmentwill assist in obtaining treatment efficiency for thewastewater treatment facilities and provide acceptableeffluent limits.

9 It is important for the Plant Operator to set aregimen for equipment operation and make the necessaryadjustments to obtain OPERATING efficiency. The followingoperational sequences are intended to help the Plant Operatorset and operate equipment of various plant OPERATIONAL SEQUENCE:A. Influent Pump StationThe raw sewage is received in the influent pump station. Collected wastewater is discharged to the aerationtank after passing through a bar screen. This pumping operation is automatic and is done by using electric drivensubmersible pumps. The pumps are controlled by four (4) mercury float switches either automatically or manually with thehand on/off switches. This pump station collects sewage flows from certain of the park s facilities, that is, a concession, restrooms, a picnic area, a recreation hall and associated rest rooms.

10 The float conditions have been set as follows: Float #1 the low level float, turns both pumps off. Float #2activates the lead pump. If water level would continues to rise from an unusual flow while the lead pump is running, 01/2001 FPSCh. 3 Pg. 6 Float #3 activates lag pump. Float #4 activates the red signal light and audible alarm in a high water condition. A alternatorinside the control panel alternates lead /lag pumps each tine they are shut off. Each pump also has a run light and elapsedtime meter at the panel to show when the pump is in use and it s run float switch liquid levels are established in the influent pump station to determine the PUMP ON, PUMPOFF, and the HIGH WATER POSITIONS within the wet basic components in this automatic and manually operated system include butis not limited to: Float switches, float stem with guides, alternator, elapsed time meters, over-load reset switch over-load circuit breakers, holding relay, red signal light, audible alarm OPERATING the pump station, the Float switch #2 rises to the PUMP ONPOSITION, the alternator activates pump No.
