District of Columbia Wastewater and Ethics 20 PDH Discount Package 2

This online engineering PDH course provides an overview of key considerations for developing or enhancing management programs for decentralized wastewater treatment systems.

 

One in every four households in the United States relies on an individual onsite or small cluster system to treat wastewater. In far too many cases, these systems are installed and largely forgotten – until problems arise. On the other hand, EPA concluded in its 1997 Report to Congress that “adequately managed decentralized wastewater systems are a cost-effective and long-term option for meeting public health and water quality goals, particularly in less densely populated areas.”

 

The key to achieving effective performance of decentralized sewage treatment systems from the simplest “box and rocks” septic tank and drainfield system to the most complex treatment and dispersal units; is an effective management strategy. This strategy must consider several critical elements such as planning, site conditions, risk factors, system design, and operation and maintenance, all of which comprise a management program.

 

This 7 PDH online course is applicable to civil, environmental and chemical engineers, sanitarians, and others seeking an understanding of Management of Onsite and Clustered Wastewater Treatment Systems.

This online engineering PDH course investigates  whether the current Centralized Wastewater Treatment (CWT) Effluent Limitations Guidelines and Standards (ELGs) are adequately managing wastewater discharges from CWT facilities accepting oil and gas extraction wastes.

 

The EPA collected and evaluated data regarding oil and gas wastewater characteristics, as well as data characterizing discharges from CWT facilities accepting oil and gas extraction wastes, which are presented in this course.

 

The exploration, development and production of oil and gas reserves vary markedly from region to region. There are a number of solid and liquid waste materials generated during oil and gas exploration, extraction and production, and these waste materials may be managed by CWT facilities. The nature and characteristics and quantity of the wastes generated depend upon a number of factors, such as the type of drilling, the characteristics of the formation, the depth of the well and the type and quantity of chemical additives used during drilling, production and well maintenance activities.

 

This 2 PDH online course is intended for chemical, petroleum, environmental and industrial engineers as well as other interested in understanding the wastewater characterization and management used at CWT to treat oil and gas extraction wastewaters.

This online engineering PDH course provides guidance on the selection process of the subsurface wastewater infiltration system. It describes various steps involved in the selection process including understanding of the prevailing design conditions, matching these conditions to system performance, establishing design boundaries and boundary loadings, evaluating the receiving environment and mapping out the site.

 

Selecting the appropriate system type, size, and location at the site depends on the wastewater flow and composition information, site- and landscape-level assessments, performance requirements, and the array of available technology options. Key to selecting, sizing, and siting the system are identifying the desired level of performance and ensuring that the effluent quality at the performance boundaries meets the expected performance requirements.

 

This 2 PDH online course is applicable to civil, and environmental engineers, as well as design and construction personnel involved with the planning, selection and design of subsurface wastewater infiltration systems.

This online engineering PDH course describes how water and wastewater utilities can be more resilient to earthquakes. It provides the best practices from utilities that have used mitigation measures to address the earthquake threat.

 

An earthquake is a sudden and violent shaking of the ground caused by movement within the earth’s crust or by volcanic activity. The water sector is particularly vulnerable to earthquake damage and service disruptions. By understanding the threat of earthquakes and the potential impacts to both the water infrastructure and the community, water utility owners and operators can make more informed decisions on earthquake mitigation options.

 

This 2 PDH online course is applicable to environmental, civil, and structural engineers as well as others interested in learning more about how wastewater utilities can be more resilient to earthquakes.

This online engineering courses is divided in to two parts: The first part discusses sewer systems that use pressure to deliver sewage to a treatment system. The second part discusses small diameter gravity sewers (SDGS) which convey effluent by gravity from a tank to a treatment location. Each part presents an overall description of the relevant topic along with the advantages and disadvantages of each system, design criteria, performance data, operation and maintenance and insights about cost related data.

 

Alternative wastewater collection systems can be cost effective for homes in areas where traditional collection systems are too expensive to install and operate. Pressure and gravity sewers are used in sparsely populated or suburban areas in which conventional collection systems would be expensive. These systems generally use smaller diameter pipes with a slight slope or follow the surface contour of the land; thereby, reducing excavation and construction costs. These systems convey effluent by gravity from an interceptor tank (or septic tank) to a centralized treatment location or pump station for transfer to another collection system or treatment facility.

 

This 2 PDH online course is applicable to civil, mechanical and environmental engineers, as well as design and construction personnel involved with the planning, design and installation of low pressure and small diameter gravity sewer systems.

This online engineering PDH course provides a discussion and detailed examples of process design calculations for a single stage BOD removal MBBR (moving bed biofilm reactor) system, a two-stage BOD removal MBBR system, a single stage tertiary nitrification MBBR system, a two-stage BOD removal/Nitrification MBBR system a post-anoxic denitrification MBBR system and a pre-anoxic denitrification MBBR system.

 

This course is Part II of a three-part series. The other two courses in this Biological Wastewater Treatment series are about activated sludge processes (Part I) and Membrane Biofilm Reactor (MBR) processes (Part III).

 

The MBBR process is an attached growth process that uses plastic carriers to provide a surface on which biofilm grows.  The MBBR process doesn’t require sludge recycle, because the biomass remains in the system attached to the plastic carriers.  The required reactor size for an MBBR process is typically significantly smaller than that for an activated sludge process treating the same wastewater flow, or for other common attached growth processes like the RBC or trickling filter. It can be used for BOD removal, biological nitrification, biological denitrification, and biological phosphorus removal.

 

This 4 PDH online course is intended primarily for civil engineers, environmental engineers, and chemical engineers. After completing this course you will be familiar with the general components and configuration of an MBBR wastewater treatment process and be able to make typical process design calculations for an MBBR process.

This online engineering PDH course introduces engineers to the National Society of Professional Engineers Code of Ethics. The Code provides ethical guidance to engineers in their various and often simultaneously held roles as 1) guardians of public health, safety, and welfare 2) employees, 3) employers, and 4) providers of technical service to clients.

 

Engineers practicing their profession encounter not only technical issues but also ethical issues. Sometimes the latter issues are easy to resolve: applying everyday, common-sense notions of honesty, openness, responsibility, and lawfulness is sufficient to guide the engineer to the appropriate decision. At other times, however, matters are more complicated. In particular, knowing what to do when two or more duties or obligations conflict can be difficult. For example, an engineer's duty to his client or employer may conflict with the engineer's duty to the general public. Codes of ethics have been formulated to help engineers address these conflicts.

 

This 1 PDH online course is intended for all engineers who are interested in gaining a better understanding about how to protect and respect their engineering profession in the utmost manner.
