Wastewater Engineering 15 PDH Discount Package 2

This online engineering PDH study provides the student with information on MBR design and operation and information about four leading MBR equipment manufacturers.

The use of membrane bioreactor (MBR) technology, which combines conventional activated sludge treatment with low pressure membrane filtration, has been proven to be a feasible and efficient method of producing reclaimed water. The membrane component of the MBR process eliminates the need for a clarifier and is performed using low-pressure membranes such as microfiltration (MF) or ultrafiltration (UF). MBR technology offers several advantages to conventional wastewater treatment including reduced footprint, consistent and superior effluent water quality and ease of operation.

A pilot study was conducted by the US Bureau of Reclamation to evaluate the MBR technology for its potential application to water reclamation. The main purpose of the study was to evaluate several leading manufacturers in an effort to encourage competition within the MBR industry. In addition, the study focused on optimizing MBR operation for water reclamation. The study included a parallel comparison of four leading MBR suppliers.

This 7 PDH online course is intended for engineers, state regulators, and water treatment professional. It provides information on MBR design, operation, and costs.  It will also assist those professionals that work in the area of upgrading and expansions of existing water and wastewater facilities or the design of new facilities. The course is suitable for a student with basic water treatment knowledge or for an advanced student that needs to brush up on water treatment basics.

This online engineering PDH course will provide a detailed evaluation of ultra violet (UV) technology as an alternative to conventional chemical disinfection methods used at wastewater treatment plants (WWTP).

Chlorination has been the preferred disinfection method used for treating WWTP effluent, but concerns about chemical releases, public safety, and the potential for chlorinated effluent to be toxic to aquatic life have caused municipal managers to consider other options.  Although chlorine, sometimes followed by dechlorination, continues to be used at many municipal WWTPs, use of other means, such as UV disinfection, is increasing. UV is a technology capable of providing effective WWTP effluent disinfection while reducing safety and environmental toxicity issues.

There are many factors that must be carefully considered to verify that UV facilities are safe, reliable and economical. These issues include the cost of power and lamp replacement, lamp fouling, ability of the water to allow transmission of UV radiation, tailing, photoreactivation and regrowth of disinfected microorganisms, and dose selection.

This 8 PDH online  course is intended for wastewater treatment engineers and environmental professionals seeking to gain an understanding of UV disinfection technologies. This course is also an excellent overview for those environmental professionals working in the field of water and wastewater treatment. A complete description of UV science is described along with its application to the disinfection of wastewater.  The three major UV technology options are fully presented and compared.  Results of a pilot demonstration are looked at to give the reader a real world example for evaluating UV technologies as an option for disinfecting wastewater at an existing plant.
