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 gastroenteritis, 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.

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 a 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.

Coliforms (total and fecal) Test:

This test helps in monitoring the increase or decrease of many pathogenic bacteria or coliforms.

Total Plate Count:

The plate count method relies on bacterial growth into a colony on a nutrient medium so that the colony becomes visible to the naked eye and the number of colonies on the plate can be counted.

Streptococci (faecal) Test:

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

Enterococci Escherichia Coli:

This test helps in determining the risk of gastrointestinal infections and other related illnesses due to E.coli.

Legionella Test:

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

Pseudomonas Aeruginosa Test:

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 infections, urinary tract infections, and in rare instances, pneumonia. As spa or purified water system operators, you should be aware of Pseudomonas, and how to control its growth.

Suspended Solids Test:

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

Total Grease Test:

This test helps in determining oil and grease concentration levels. It 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.
