Sources• Municipal/domestic waste water• Strom water discharges•Hotel and Offices• Agricultural runoff• Landfill leachates• Industrial wastewater

Environmental and Health Impact• Ground water pollution• Eutrophication of lakes and other water bodies• Degradation of river water quality• Impact on public health

Treatment• Reuse/recycle• Avoiding contaminations in water bodies• Decentralized approach for reducing pressure on civic bodies

Subsurface Flow System Reduced odour – no

wastewater at surfacePropagation of insects is

also controlled Microbes that treat the

wastewater live on the gravel, soil and plant surfaces

plants provide oxygen and food for the microbes

3. Equipment Requirement (excluding screening and grit removal common to all processes)

Aerators, recycle pumps,

scrappers, thickeners, digesters, dryers gas equipment

Nil except gas collection and

flaring gas conversion to

elect is optional

Aerations, recycle pumps sludge,

scrappers for large settlers

Aerators only

Water pump(no pump is required if

flow by gravity).

4. Operational Characteristics

Skilled operation

Simpler than ASP Simpler than ASP

Simple Unskilled operator

5. Special features Considerable equipment and

skilled operation reqd specially when gas collection

and usage considered

Minimal to negligible power reqd. makes it economical at

even if gas revenue is neglected

BOD removal highest effluent

nitrified high power reqd. Favoured for

small and medium plants

Power reqd. similar to

ASP operation simpler

Plant species and odour

less operations

•Conventional & Mechanized technologies like ASB, UASB, SBR, MBBR are too expensive and require 30% of the capital cost as annual O&M costs. At an average these processes pose water treatment costs of Rs 6-8/ 1000 Liters.

•In case where gravity may not work single pump shall be required for maintaining water flow.

ADVANTAGESCost-effectiveOperation and maintenance expenses are negligible.Minimum electricity requirementSmaller footprint (Retention time: Typically less than 24 hrs.)Facilitates recycle and reuse of waterNo foul odor and No Mosquito Nuisance.Tolerates fluctuations in operating conditions such as flow,

temperature and pH

PHYTORID system is useful for treatment of waste water in following applications

Domestic wastewater (including decentralized Municipal waste water treatment) Colonies, Airports, Commercial complexes, Hotels Open drainage Cleaning of nallah water

Agricultural wastewater Dairy waste Slaughter House Waste Fish pond discharges Pre treated industrial wastewater (PHYTORID can be polishing) Municipal Landfill leachates Several other applications

Product Water quality

Treated water complies to the regulations laid down by CPCB to reuse the water for the purpose of discharge, gardening agriculture etc. For flushing and cooling tower uses, tertiary treatment will be required.

Page 14: Phytorid presentation by a3 s enviro

Green pointsBest Adoptable technology for treatment and reuse of

waste waterPhytorid Technology carryout on-site treatment and reuse

of grey water up to 95%, which would attract total of 5 credits on Indian Green Building Certification (IGBC).
