Flow rate and operation of slow sand filter explained along with gradiation of fine sand and gravel below the source water.
Flow rates of 0.015-0.15 gpm/ ft^2 expected for typical performance with entry water of < 10 NTU..
Two day period of establishing Schmutzdecke Algal layer on the surface of the slow sand filter is explained and how that period sends water passing though back to the waste water well rather than stored in the clearwell.

Peace Engineering Program Announcement
[ECHO Program Concept]()
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
Support this work
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.
