Testing Services Offering:

Bacteriological condition:

This test helps in determining the contamination by potentially harmful bacteria and other micro-organisms. Short term gastrointestinal disorders and illnesses such as gastro-enteritis, giardiasis, typhoid, dysentery, cholera, and hepatitis have been linked to water contaminated by microorganisms. The micro-organisms which find their way into a water supply can come from a variety of sources including sewage, animal wastes, or dead and decaying animals.
Test Method:

Biochemical oxygen demand:

This test helps in determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period. It is not a precise quantitative test, although it is widely used as an indication of the organic quality of water.
Test Method:

Coliforms (total and faecal):

This test helps in monitoring the increase or decrease of many pathogenic bacteria
Test Method:

Total Plate count:

The plate count method relies on bacteria growing a colony on a nutrient medium so that the colony becomes visible to the naked eye and the number of colonies on a plate can be counted.
Test Method:

Streptococci (faecal):

This test helps in determining the information about the source of contamination.
Test Method:

Enterococci Escherichia coli:

This test helps in determining the risk of gastrointestinal infections and other related illnesses.
Test Method:

Legionella:

This test helps in identification of food poisoning bacteria including Salmonella, Listeria, E.coli O157, Campylobacter and Clostridium perfringens.
Test Method:

Pseudomonas aeruginosa:

Pseudomonas aeruginosa is a bacterium commonly found in spas and purified water systems. If allowed to reach unsafe levels. The presence of pseudomonas may cause several health problems including skin rash and other skin infections, ear infection, urinary tract infection, and in rare instances, pneumonia. As spa or purified water system operators, you should be aware of pseudomonas, and how to control its growth.
Test Method:

Suspended solids:

This test helps in determining the water quality. Suspended solids refer to small solid particles which remain in suspension in water as a colloid or due to the motion of the water.
Test Method:

Total grease:

This test helps in determining oil and grease concentration levels is important for offshore oil platforms, refineries and oil depots. It can also be operated flexibly to address a series of process issues. The most common sites of operation are prior to and after water purification systems, such as primary to tertiary water separators, water feeds and filtration equipment.
