Jal-TARA Water-testing Kits
Anybody and everybody can use
Jal-TARA water testing kits because they are provided with a
self-explanatory pictorial manual. These kits are lightweight and
sturdy, and can be easily transported for fieldwork. We offer two
standard kits. One kit tests 11 essential parameters, including
biological, chemical and physical parameters of drinking water, while
the other kit tests both surface and drinking water, which can assess 14
parameters. The various parameters tested by the standard kit are pH,
temperature, turbidity, fluoride, ammonia, nitrate, hardness, dissolved
oxygen, phosphorous, chloride, residual chlorine, iron, and biological
contamination. Each kit includes gloves, beakers, trays, test tubes,
syringes, reagents, and colour comparison charts, along with a detailed
pictorial manual. There is also the option to purchase the English
language training video for use of the kits.
TEMF also offers customised
kits on demand. These kits can test the levels of pH and fluoride, pH
and nitrate, pH and iron, pH and residual chlorine, hardness, dissolved
oxygen and total dissolved solids (TDS) meters. An arsenic testing kit
is also available. Each kit contains all the necessary equipment and
accessories. Refills are also available for all our kits. Thousands of
such kits have been supplied to various departments across the globe.
The state governments of Himachal Pradesh, Jharkhand and Bihar have
recently put these kits to use under the National Rural Water Quality
Monitoring and Surveillance Programme, Ministry of Rural Development,
Government of India.
Jal-TARA Aqua Check Testing
Vials
The Jal-TARA Aqua Check vial is
a small bottle that proves the presence of bacteria that cause diarrhoea,
dysentery and gastroenteritis. In this simple to use kit, just open a
vial, fill it with water up to the mark, and let it sit. Within 48
hours, the water will turn black in the presence of bacteria. A set of
10 vials is a part of the standard kit.
Our water-testing kits,
validated by the Shriram Institute of Industrial Research (SIIR) and
supported by UNICEF in 2005, are used extensively in schools, Public
Health Engineering Departments, world bodies like the UNICEF as also in
developing countries like Bhutan, Sri Lanka and Africa. The licensing
for our TARA Aqua-Check vials has been given by the National Research
Development Corporation (NRDC), Delhi and the technology is based on the
DRDE (Gwalior) H2S strip method.
Jal-TARA Water Filter
The Jal-TARA water filter uses
slow sand filtration to treat water contaminated with harmful bacteria
and sediments. The unclean water trickles down through various layers of
sand, and safe drinking water settles at the base of the filter. The
filter is customised in a 1000-litre water tank and processes between
2500 to 3000 litres of drinking water every day, which is enough to meet
the needs of 100-120 households. This is a highly effective way of
providing safe drinking water, eliminating 99.99% of the bacteria, while
also protecting people from illnesses such as typhoid, dysentery, and
diarrhoea. One filter will last for around 15 years, and needs cleaning
only once a year. A total of 48 such filters have been installed in
various schools, offices and villages in India.
There are several benefits of this testing
strategy:
JAL-TARA Arsenic
Purification System
Scientists and analysts at DA
have developed the Jal-TARA Arsenic purification system, an innovative
drinking water treatment device for removing arsenic, pathogens, iron,
turbidity and other contaminants in drinking water. The filtration
mechanism is based on slow sand filtration and iron hydroxide adsorption
principles. Studies have showed that the percentage removal of arsenic
from water is in the range of 85-95%, along with other parameters.
Percentage removal also varies in field conditions.
Fluoride Removal Filter
The fluoride removal filter
unit essentially consists of an upper chamber which holds the raw or
untreated water, through which water comes in contact with a bed of
Activated Alumina (AA) granules and passes through at a slow rate
through a small orifice at the bottom of the upper chamber. To protect
the AA bed every time water is poured into the chamber, a perforated
baffle plate is placed over the layer of AA.
Jal-TARA Household Water
Filter
At the household level, the Jal-TARA
water filter is a version of slow sand water filter specifically
designed for removing disease-causing organisms. The filters can be
built on a smaller scale at a lower cost even in remote areas. The
technology has been introduced in more than 30 countries and is widely
used by various agencies.
TEMF offers a range of quality
products and services for environmental quality monitoring and
management. It is our belief that effective management can only come
from effective monitoring, because it allows for a precise situation
analysis, which can then lead to appropriate management solutions.
