1. Phytorid Technology for Sewage and Industrial Wastewater Treatment

Introduction:-

PHYTORID is a scientifically developed systematic

treatment methodology for waste water.

PHYTORID combines Physical, Biological and

Chemical processes.

Works on gravity

No electric power requirement

Scalable technology

Easy to maintain

Adds to aesthetics

Cost effective

TYPICAL DESIGN FEATURES

The general concept design for the Phytorid system is presented in Figure 1. However, the design may be

further modified as per specifications and land availability.

Figure 1: Cross Sectional View of Phytorid System

The sub-surface flow type, Phytorid system is proposed for the treatment of sewage or domestic or

industrial wastewater which will consists of a basin or a channel with a barrier to prevent seepage, but the

systems/ cells/ beds contain a suitable depth of porous media. A primary treatment facility would also be

constructed along with basic for effective removal of solids and thus reduces the marginal BOD.

The porous media also supports the root structure of emergent vegetation. The design of the Phytorid

system assumes that the water level in the cells will remain below the top of the filter media.

The vegetation to be utilized for the said Phytorid system is very important. Various species of aquatic

plants have been utilized to attain maximum efficiency in the treatment of domestic wastes. These

include species like Phramites australis, Phalaris arundinacea, Glyceria maxima, Typha spp., Scirpus

spp., other common grasses etc.

ADVANTAGES OF PHYTORID TECHNOLOGY

Treatment efficiencies for the removal of faecal coliforms, BOD, COD, nutrients are up to 95%,

which is greater than the traditional chemical methods.

It is a very cost effective technology when compared with the traditional wastewater treatment

methods.

Since it utilizes natural vegetation and rhizosphere microorganisms, it is eco-friendly method of

treating sewage.

An important factor to be considered is the aesthetic improvement that is provided by this

methodology.

No mosquitoes and odour nuisance

The treated water can be used for enhancement of environmental architecture such as roadside

fountains.

The quality of treated water is comparable to irrigation standards

TREATMENT EFFICIENCIES

Phytorid system being natural method, the final efficiencies as indicated in Table 1, will be achieved

after the system is stabilized which may require a period of 6 months after commissioning.

Table 1: Performance of PHYTORID for urban waste

Pollutant Performance (% removal)

Total suspended solids 75 – 95

Biochemical oxygen demand 70 – 80

Chemical oxygen demand 60 – 75

Total nitrogen 60 – 70

Phosphate 50 – 60

Fecal coliform 85 – 95

Quality of Treated Water: The treated water will meet the quality suitable for gardening purpose.

OPERATION AND MAINTENANCE

This technology is natural system; as a result operation is mostly passive and requires little operator

intervention. Requirement for area can change on various factors such as load (kg BOD/day), ambient

temperature, topography of the region, flow characteristics, etc. Maintaining uniform flow across the

Phytorid system through inlet and outlet adjustment is extremely important to achieve the expected

treatment performance. Sampling of inlet and outlet will be carried out for a period of 3 months every

fortnight after stabilization of the treatment systems for first one year.
