Wastewater Treatment

Syllabus

Lesson 1- Types of Microbial Growth. This chapter examines the various types of microbial growth- algae, bacteria, aerobic and anaerobic, and fungi. We also review identification techniques available to understand these organisms.

Lesson 2- Problems Associated with Microbial Growth. Here we review how biofilm matrices are formed, and their impact on process equipment, including fouling and microbiologically influenced corrosion.

Lesson 3- Physical and Chemical Factors that Affect Microbial Growth. We review factors that contribute to microbial growth on surfaces. We also assess the impact of ambient temperature, pH, nutrient availability, water velocity against the surface, and surface roughness on fouling.

Lesson 4- Available Biofouling Treatment Technologies. We introduce options for treating microbial growth- industrial biocides, oxidizing agents, non oxidizing agents, and emerging technologies.

Lesson 5- Chlorines. Chlorine compounds (i.e. sodium and calcium hypochlorite) available for use, the background chemistry, measurement and monitoring systems, feeding requirements, and environmental and safety concerns are introduced.

Lesson 6- Bromines. Bromine compounds (i.e. bromine chloride, activated bromine, and others) available for use, the background chemistry, measurement and monitoring systems, feeding requirements, and environmental and safety concerns are introduced.

Lesson 7- Chlorine Dioxide. Chlorine dioxide compound available for use, the background chemistry, measurement and monitoring systems, feeding requirements, and environmental and safety concerns are introduced.

Lesson 8- Peroxygens. Peroxygen compounds (i.e. hydrogen peroxide, peracetic acid, etc) available for use, the background chemistry, measurement and monitoring systems, feeding requirements, and environmental and safety concerns are introduced.

Lesson 9- Non Oxidizing Agents. Non oxidizing biocides such as PHMB, quaternary ammonium compounds, organo bromine, glutaraldehyde, organo sulfur compounds, DBNP, and others are introduced.

Lesson 10- Equipment Cleaning. Simple options for treatment, such as manual cleaning of surfaces, use of abrasive cleaning agents, and other treatments are introduced.

Lesson 11- New Biofouling Treatment Technologies. Emerging treatment such as biodispersants, enzymes, bioelectric application, application of surface coatings, and Ultra Violet light are introduced.

Lesson 12- Control Efficacy. This is a review of your control plan going forward.
