Wastewater Treatment SystemsFor ReuseMarch 22, 2016
1
The practice of capturing wastewater from homes and businesses, treating it to a high quality, then delivering the water for reuse.
Recycled water can satisfy most water demands, as long as it is adequately treated to ensure water quality appropriate for the use.
Nonpotable uses:, landscape, public parks, and golf course irrigation, artificial lakes and agriculture.
2
Drought in California and the Southwest: Legislation requiring reuse in golf courses, landscaping and in new commercial buildings (new San Francisco ordinance)
Cost of municipal water is rising
State and regional government incentives
Growing number of states adopting guidelines for water reuse (+33)
3
Largest commercial water users: offices, schools and golf courses, followed by restaurants and retail
Office parks, schools and golf courses would benefit most from reusing wastewater for irrigation.

We take domestic wastewater and give it back to you as clean, disinfected water for onsite irrigation.

Flexible configuration options are ideal for decentralized,
onsite wastewater treatment for a wide range of flows

Biological treatment to digest organic matter
Sludge settles and is removed
Finer suspended solids are removed in the specially designed sedimentation tank

Disinfection using chlorine dosing
or Optional UV disinfection
15
Tertiary filtration options:
Sand filter: removes fine suspended solids,
Activated Carbon Filter: removes color, odor, or non bio-degradable materials
Ultrafiltration: removes microorganisms and pathogens (down to 1 micron)
Result: crystal clear water for reuse.
From treated water tank
To reuse (irrigation)
Federal: EPA and National Pollutant Discharge Elimination System (NPDES)
State: permits issued by state agencies (e.g. Department of Environment, Department of Health & Human Services, Department of Health, etc.)
Counties / municipalities: may be involved in issuing permits as well (usually business-specific)
16
International, independent, ANSI-accredited wastewater treatment testing and certification organization
Standards recognized by most state regulatory agencies
Industry standard “stamp of approval” for small-flow onsite wastewater treatment systems (less than 3,000 GPD)
NSF standards meet or exceed most state permitting regulations for larger decentralized systems as well

Miracell-Green (with disc filter) meets NSF-40 standard for subsurface discharge (dripline irrigation)
Miracell-Blue (with Ultrafiltration) meets NSF-360 standard for reuse (spray irrigation)
