TERRAFIL TECHNOLOGY FOR IRON REMOVAL
Terrafil filters are used for removal of sediments, suspended particles, iron & bacterial contamination in drinking water.
This Technology is developed by the Institute of Mineral and Materials Technology, Bhubaneswar ( CSIR) and transferred licence to our company for manufacturing the units both community & house hold units.

TERAFIL WATER FILTERS
The Terafil water filter is especially for those
areas where drinking water is drawn from
both surface & ground water sources like dug
wells, ponds, tube wells and rivers where
water is rich in sediments, suspended
particles, iron and microorganisms.
![Page 10: Terafil Water filters_Sri Sai water treatment pvt ltd._Indovation 2015_23 January 2015](https://reader030.fdocuments.in/reader030/viewer/2022032616/55a49c331a28abe1388b457c/html5/thumbnails/10.jpg)
MAKING TERAFIL DISCS:
Terafil is a burnt red clay porous media produced from
mixture of red clay (silt clay), river sand and wood saw dust,
without using chemicals. The dough of the mixture of these
materials is sintered at high temperature in a low cost
coal/wood fired furnace to make the terracotta disc porous.
Sand particles form nuclei, over which clay particles get
embodied thus leaving pores in between them due to
burning of wood particles during the process of sintering
The dimensions of the disc :
Thickness - 50mm, diameter – 100 & 220 mm

![Page 13: Terafil Water filters_Sri Sai water treatment pvt ltd._Indovation 2015_23 January 2015](https://reader030.fdocuments.in/reader030/viewer/2022032616/55a49c331a28abe1388b457c/html5/thumbnails/13.jpg)
PROCESS OF FILTRATION
Terafil is rigidly fixed at the bottom of the top
container and raw water is allowed to pass
through the Terafil disc.
All the sediments ,impurities, bacteria and
iron are left on the surface of the Terafil disc.
The clear & purified water is collected in
the bottom container.

![Page 15: Terafil Water filters_Sri Sai water treatment pvt ltd._Indovation 2015_23 January 2015](https://reader030.fdocuments.in/reader030/viewer/2022032616/55a49c331a28abe1388b457c/html5/thumbnails/15.jpg)
EXTENT OF TREATMENT
About 99% of turbidity, 90-95% of micro-organisms, 90-95% of soluble iron, colourand bad odour are effectively removed from the raw water during filtration process through the Terafil.
100% bacteria can be removed when a pinch (0.01 gm) of bleaching powder is added to a liter of filtered water.

MAINTENANCE OF THE FILTERS
The iron, sediments and other impurities
gets precipitated on the surface of the disc
and clog the core of the disc which reduces
the efficiency of the filtration over a period of
time.
These impurities should be cleaned from to
time to increase the life of the disc and also
to get good filtration rate.
![Page 17: Terafil Water filters_Sri Sai water treatment pvt ltd._Indovation 2015_23 January 2015](https://reader030.fdocuments.in/reader030/viewer/2022032616/55a49c331a28abe1388b457c/html5/thumbnails/17.jpg)
EFFICENCY OF FILTRATION
Average rate of filtration is 13ml/hour/unit
area (cm2 ) of top surface of the disc with
raw water having 50 NTU turbidity and 250
mm water head.
Rate of filtration is dependent upon turbidity
and pressure of raw water over the Terafil
disc
![Page 18: Terafil Water filters_Sri Sai water treatment pvt ltd._Indovation 2015_23 January 2015](https://reader030.fdocuments.in/reader030/viewer/2022032616/55a49c331a28abe1388b457c/html5/thumbnails/18.jpg)
CLEANING OF THE FILTER
The top surface of the disc shall be cleaned
by scrubbing with a soft nylon or coir brush
or with water jet to remove the sediments
deposited on the discs and to open up the
clogged pores of the disc for rejuvenation of
the filtration process.
