This question comes from the California Wastewater grade 3 certification exam sample questions that can be found here: http://www.swrcb.ca.gov/water_issues/...

The problem reads: In an attempt to correct a filamentous growth in an activated sludge process, you want to inject chlorine into the RAS flow stream at the dosage of 2.5 pounds of chlorine per 1000 pounds of return activated sludge suspended solids. Show the calculations to find the proper chlorinator feed setting (in pounds of chlorine per day), given the following information:

Average Plant Flow Rate 9.0 MGD - MLSS Conc. 2850 mg/L RAS Flow Rate 3.3 MGD - MLVSS Conc. 2600 mg/L WAS Flow Rate to DAF 1.2 MGD - RAS Conc. 8500 mg

About SCD Hub

  • SCD Hub’s mission is to serve as a hub for sustainable community development in order to provide trustworthy development & training tools to facilitate project planning, design & execution.

  • SCD Hub serves a curated collection information supporting best practices in sustainable community development, at this time we are working closely with the new UNM Peace Engineering program improve the quality of our database and improve how it serves the short, medium and long term planning goals of projects.

  • Our current work emphasizes the life cycle of water. The list of outcomes is fine for a start. Clearly defined project goals and objectives are a crucial element for planning the activities and inputs required to launch and sustain a project. -Bernard Amadei, Ph.D., NAE

Approach

SCD Hub’s pioneering work with UNM Peace Engineering program’s technical solutions library needs your support! We are working to document solutions for safe, affordable, accessible, and appropriate relationship with the lifecycle of water - from source to distribution, to disposal. Solid waste management lifecycle is also being researched in our library curation process.
