Slide 1

Muck Management & Closure Procedures for Anaerobic Lagoons Prepared by: Ron Sheffield Biological & Agricultural Engineering

Slide 2

What is Sludge? Regular result of anaerobic absorption Dead microbial cell mass Rich in supplements May be called biosolids or residuals Settled inorganic matter garbage (pens, bottles, veterinary supplies) shakes and sand

Slide 3

Properties of Sludge Color: Black Consistency: depicted as a lumpy tar or like fruit purée Particle measure: to a great degree little, hard to separate/dewater Odor: essentially not as much as crude fertilizer, yet more than "pink" tidal pond gushing

Slide 4

Nutrient Concentrations Table 2

Slide 5

Sludge Accumulation Layer

Slide 6

Sludge Storage Volume Sludge stockpiling is required to keep up a satisfactory perpetual treatment volume Necessary to bolster bacterial development and legitimate level of excrement treatment and smell control Majority of tidal ponds composed before 1996 don't have any or sufficient ooze stockpiling Sludge stockpiling is not required for existing operations to be confirmed

Slide 7

Undersized Lagoons Increase the requirement for more serious administration and pumping recurrence Loss of "pink or purple" shading and related advantageous microorganisms Increase scent potential Increase supplement levels in tidal pond profluent Increase the rate of slime development

Slide 8

Principles of Sludge Management 1. Distinguish practices to minimize muck amassing 2. Distinguish "Trigger Point" for ooze expulsion 3. Screen slop aggregation in connection to "Trigger Point" 4. Try not to expel the last 2 ft of slop 5. Secure the respectability of earthen liner 6. Arrive apply at agronomic rates 7. Minimize smells

Slide 9

Minimizing Sludge Production Rate of tidal pond ooze development can be diminished by: appropriate tidal pond estimating mechanical solids detachment of flushed waste gravity settling of flushed waste solids minimizing nourish wastage and spillage

Slide 10

Lagoon Operation Sludge Removal: Lagoon slop that is evacuated every year instead of put away long haul will: have more supplements have more scent require more land to legitimately utilize the supplements

Slide 11

"Trigger Point" Physical profundity in tidal pond where ooze surpasses the assigned ooze stockpiling layer Insures that muck collection does not decrease the perpetual treatment volume (PTV) Minimum: 1 cu.ft. PTV/# SSLW Use Worksheet 1 to ascertain Sludge ought to be evacuated once collection comes to the "Trigger Point"

Slide 12

"Trigger Point" Sludge Accumulation Layer

Slide 13

Monitor Sludge Depth Estimate Sludge Depth Based on gathering rate Seasonal pump down Once pumped down to quit marker,observing slime now by and large implies that the ooze volume has surpassed reasonable capacity and ought to be expelled Measure Sludge Depth

Slide 14

Measuring Sludge Depth Use a 14' long lightweight inflexible shaft Take at least 10 estimations from around tidal pond Avoid ranges around: Inlet funnels Recycle pumps Irrigation admissions Measure profundity of tidal pond underneath the top pumping marker - a.k.a. "Begin" pumping marker

Slide 15

Measuring Sludge Depth 1. Measure the profundity of supernatant. Profundity = 6.5 ft 2. Measure the profundity of muck. Profundity = 10 ft 6.5 ft 10 ft 3. Slime profundity: 10' - 6.5' = 3.5ft

Slide 16

Estimating Lagoon Volume Once you have figured the normal profundity of muck you can ascertain the volume of ooze assessing expulsion costs ooze application arranging Use Worksheet #1 Requires: Lagoon/Farm relentless state live weight, changeless treatment volume, berm incline, tidal pond measurements Information can be found in ranch's Certified Waste Management Plan , contact neighborhood S&WCD for duplicate

Slide 17

When Removing Sludge Do not expel the last two feet of ooze, if the tidal pond is to stay in operation Insure the trustworthiness of the earthen liner minimize sidewall disintegration by fomenter pumps screen draglines so administrators are not evacuating soil alongside ooze redirect all spillover minimize and control

Slide 18

Land Applying Sludge As with different squanders, dependably have your tidal pond slop investigated for its supplement esteem. Slime tests ought to be taken preceding area application A waste use plan is required to be produced for all fields getting muck applications

Slide 19

Land Applying Sludge Maintain application records IRR-1/IRR-2 or SLUR-1/SLUR2 Apply just to developing yields, or those which will be planted or breaking lethargy inside 30 days Soil joining or infusing connected slop is prescribe to minimize smells & flies, and to avoid spillover

Slide 20

Land Applying Sludge - P Issues Lagoon ooze has a much higher phosphorus content than tidal pond fluid. slop ought to be connected to arrive with low phosphorus, as demonstrated by a dirt test, and joined to decrease the shot of spillover ooze connected to fields with high soil test phosphorus ought to be connected just at rates equivalent to the harvest expulsion of phosphorus

Slide 21

Application Options Irrigation Tank Spreader Surface communicate Injection Umbilical Hose Injector Manure Spreader

Slide 22

Advantages less costly simplicity of operation use existing hardware Disadvantages requires weaken muck & water/gushing blend gear disintegration/wear by slime particles style, float and scents to avoid stopping up, water system lines and gear ought to be flushed after every day with emanating or crisp water Irrigating Sludge

Slide 23

Application Using Spreader Equipment One critical issue is the "trafficability" of the fields, or how effortlessly your gear can be worked to get uniform waste application without rutting the field or bringing about soil compaction. Once the choice has been made to perform squander application, you should know about your gear's waste application rate. This requires the alignment of the land application gear.

Slide 25

Advantages give more transport portability permit coordinate soil infusion Disadvantages require additional time and work have higher working expenses require enhanced travel streets and appropriate soil trafficability soil compaction Pump and Haul Systems

Slide 26

Umbilical Hose Application Systems

Slide 28

Advantages give more transport versatility permit coordinate soil infusion requires less time and work than tank spreaders Disadvantages requires additional time and work than water system higher tractor HP prerequisite if infusing require enhanced travel streets and legitimate soil trafficability Umbilical Hose Application Systems

Slide 34

Advantages lessen number of treks minimize pulling water less expensive to pull longer separations Disadvantages extremely hard to dry solids or separate fluids extra taking care of & preparing hard to adjust less uniform application Manure Spreader

Slide 35

Taking a Sludge Sample Prior to tumult - Step 1. Utilize 14 ft long 3/4" PVC 2. With gloves on, embed pipe to the base of the tidal pond 3. Put thumb over the end of pipe framing a vacuum and gradually raise the pipe out of the tidal pond 4. Lift the end of the PVC pipe over the mouth of a 5-gallon can

Slide 36

Taking a Sludge Sample Prior to tumult 5a. In the event that totally blending tidal pond, then Use for water system or hose-drag infusion expel your thumb and place the whole substance of the pipe into the 5-gallon pail gather no less than 5 tests from around the tidal pond blend tests in plastic bucket,and send sub-test for examination

Slide 37

Taking a Sludge Sample Prior to unsettling 5b. In the event that dewatering tidal pond before disturbance, then Use for tank spreader or slime dewatering gradually break the vacuum by expel your thumb from the end of the pipe put just the dark slop in the 5-gallon pail, occupy supernatant once more into the tidal pond gather no less than 5 tests from around the tidal pond blend tests in plastic bucket,and send sub-test for examination

Slide 38

Sampling Sludge Prior to Agitation 1. On the off chance that flooding, take a tidal pond center (supernatant and slime) 2. In the case of dewatering tidal pond, test slime just Take no less than 8 tests from around the tidal pond, blend altogether and send sub-test to lab

Slide 39

Taking a Sludge Sample During unsettling Draw down supernatant, if appropriate Agitate tidal pond Collect at least 8 tests from around the tidal pond like taking tidal pond test maintain a strategic distance from clusters of ooze Place tests in plastic container, blend, and send sub-test for investigation

Sludge Removal Techniques Hire a custom instrument Agitation Dewatering Soil joining

Slide 41

Hiring a Custom Applicator Applicators are accessible to give practically "turn-key" ooze evacuation benefits However, most don't: get ready waste use arranges, or arrange adjustments test tidal pond ooze preceding application contact neighboring landowners for land accessibility finish required records

Slide 42

Hiring a Custom Applicator Cost Range: 1.5 ¢ - 5.0¢ for every gallon of fluid (1998) Factors influencing cost Lagoon finish off or general ooze expulsion Land accessibility close tidal pond Site access for fomentation gear - a greater amount of an issue for inert tidal ponds Application strategy Soil infusion or fuse
