Rural, Onsite & Small Community Wastewater & Waste Management Facultative & Anaerobic Lagoons
Lagoon Systems Objective Create an ideal environment for microorganisms to consume waste organic matter High strength waste - anaerobic lagoons Wastewater - Facultative lagoons AKA Stabilization ponds
Anaerobic Lagoons Natural continuation of the breakdown of food in the body Digestion without oxygen
Acid Formers Tough Can produce organic acids over a wide range of environmental conditions Organic acids Lower pH of lagoon Smell bad !!!
Methane Formers Delicate Easily upset by Low pH - below 6.7 High salt concentration (8mmhos/cm)
1 Stage Anaerobic Lagoon
2 Stage Anaerobic Lagoon
Startup Start in Summer About 1/2 full of clean water Slowly add waste at first Design loading after 1 year
Loading Continuous Check pH Add lime if below 6.7
Pump out Annually Down to minimum treatment volume Avoids salt buildup If salts are over 8 mmhos/cm Pump some out and add dilution water
Anaerobic Lagoons Natural treatment system No power required Tend to be large Dilution Long treatment time Low, but daily management
Stabilization Pond Sometimes called facultative lagoon Digestion with oxygen Used to treat wastewater
Stabilization pond Shallow basin Microorganisms at natural concentration
Role of Algae
Design BOD loading Hydraulic residence time 3 to 12 months
Loading Can tolerate fluctuations in loading Keep inlet below surface to control odors
Management Maintain banks Keep weeds from growing in water Keep burrowing animals out Keep trees from growing
Management Maintain lnlet & Outlet Structures Keep sludge from accumulating Watch for signs of erosion Exercise valves
Discharge Ideal for irrigation systems Appropriate level of treatment Storage to maximize flexibility for operator
Sludge Management Debris may wash up on banks Pretreat with screens Small amounts of stabilized sludge can be entrained in irrigation system
Stabilization Ponds Reduced management No power requirement Low labor time and training Limited sludge management
Stabilization Ponds Large Treatment takes a long time Affected by winter conditions
Relative Size Fixed Flim 1x Lagoon 6x
Reduce the Size? Stirring Improves air transfer Increases contact between micoorganisms and waste
Impact of Stirring Pond can be Smaller Deeper Shorter residence time
Impact of Stirring Power required More operator time & training More sludge is generated
