What you'll learn

  • Understand what agriculture land application (ALA) is
  • Learn how to calculate the agronomic rate determination (ARD)
  • Understand what "domestic septage" is and why it's relevant to biosolids management
  • Define the ways to control biosolids beyond simple management approaches
  • Understand how biosolids are relevant to modern issues, including COVID-19

Course content

3 sections • 12 lectures • 1h 32m total length

  • Agriculture Land Application (ALA)3:28

    Agricultural land application is the most used biosolids recycling method; set rate in dry tons per acre by agronomic crop needs or pollutant limits, and address odor and nuisance issues.

  • Agronomic Rate Determination (ARD)11:36

    Calculate the agronomic rate by estimating plant available nitrogen per dry ton from nitrate, ammonia, and organic nitrogen, adjusted with volatilization and mineralization factors, using a liquid biosolids example.

  • Domestic Septage10:29

    Explain domestic septage under Part 503, applied to non public sites with no pollutant limits, using the 0.0026 factor to calculate gallons per acre and lime treatment for pathogen control.

  • Important Conversion Factors with Example Problems Part 121:26

    Link percent solids to dry and wet ton conversions to determine plant available nitrogen for agronomic rate. Then convert wet tons to gallons per acre using 8.34 lbs per gallon.

  • Example Problems Part 25:24

    Apply a systematic, multi-step method to calculate dry ton per acre from 800,000 gallons of 3% biosolids on a 45.9-acre field, yielding 2.2 dry tons per acre.

  • Example Problems Part 32:27

    Convert copper concentration from dry mass to wet mass using total solids percentages, as shown with 25 mg/kg dry solids and 22% total solids.

Requirements

  • Highschool level understanding of math; recommended you have at least a basic calculator
  • Highschool level understanding of biology, chemistry, and environmental sciences
  • Completed "Biosolids Land Applier Certification Training Day 2: Part 1"

Description

Part 2 of Day 2 of this certification training course!

Every year, water reclamation facilities generate tens of millions of tons of organic residuals known as sewage sludge. The question of what to do with this material remains a financial and public health challenge for water utilities, government health agencies and other environmental and public-policy stakeholders. Given the legal ban on ocean disposal and the exorbitant costs associated with landfilling and incineration, residuals recycling (or beneficial use) has become the financially preferred option for sewage sludge management.

In the United States (US), sewage sludge recycling is a regulatory process that is defined by Title 40 of the US Code of Federal Regulation Part 503 Subpart B (Part 503). The first step in this process is the legally-recognized transformation of sewage sludge into biosolids. By regulatory definition, biosolids are sewage sludge that meets the nationally-recognized quality requirements necessary for environmental recycling.

Biosolids beneficial use represents a new and exciting approach to enhance agricultural production, combat climate change and achieve environmental sustainability. A new technical series narrated by Dr. Mike McFarland explores the myriad options for recycling biosolids to protect ecological resources and enhance food security. An excellent course for those seeking land applier certification.

In Day 2, Part 2 of this online course, Dr. McFarland will focus on the following topics:

  1. Agricultural Land Application (APA)

  2. Agronomic Rate Determination (ARD)

  3. Domestic Septage

  4. Methods To Control Biosolids

  5. Relevant Biosolids Issues

And at the end of this module, there will be the final practice test!

Who this course is for:

  • Anyone seeking to complete the land applier certification exam
  • Those who own land, work in agriculture, etc., who want simple, cost effective approaches to successful biosolids waste management
