DESCRIPTIOONS:
Demineralized water is used in several applications such as for cleaning, rinsing in industries producing Pharma products, Food Products, Alcohol Brewing, Cosmetics, electroplating etc, apart from its extensive use in steam generation in Boilers for process use as also for power generation, therefore making it important to determine the quality & suitability D M Water for use in these various applications. One critical use of De-Mineralized water is in making of saline, injected for treatment used in various diseases in hospitals, and hence should be pure to least cause any health impacts. Purity of distilled water is essential to achieve accurate results in various analytical test performed. Distilled water is also used for sterilizing medical equipment’s, batteries, automotive cooling systems to ensure optimum performance. And hence should be free of any dissolved ions etc.

DESCRIPTION:
Oceans brim with life, from tiny fishes to all the other ocean creatures. Instances of pollution such as spillage from ships, boats, processing plants can deliver destructive materials into the sea, thereby making it perilous to ocean life. Thereby making it imperative to check quality of sea water consistently to ensure it is safe & spotless. Many relishes sea food, if sea water is not perfect, the fish will not be safe for eating. Sometimes harmful synthetics & microbes can get into the fish, that one would consume, thereby throwing the ones health into deep peril. Testing of sea water helps identify the spills immediately & clean it up. Regular testing of sea water is also required to ensure fish one consumes is safe for eating. More-over numerous species in the ocean are at at risk of extinction due to contamination, environmental hazards etc, and hence testing can assist safeguarding these vulnerable species & also preserve ocean life.

DESCRIPTIONS:
Demineralized water are those in which minerals & salts are completely removed, and is often called as de-ionized water used as feed in Boiler for steam generation, however, microbes present in raw water have often shown to be present in de-ionized water due to growth of algae, fungi, bacteria in wet surfaces. These therefore results in adversely affecting the equipment performance, promote corrosion & accelerate deterioration of material. Therefore, making it essential to undertake regular Bio-Monitoring of the Boiler Feed & its raw water. Demineralized water is also used in many applications such as rinsing in chemical, pharmaceutical, & food industry, which subsequently are a matter of consumption by Human Beings & hence required to be free of any microbes. Distilled water is those that have been completely purified and removed of all contaminants, used extensively in laboratory analytical procedures, where testing requires using of pure clean water to get accurate results of analysis, and hence should be free of any traces of microbial interference.

Water is the basic necessity of every human being and therefore water analysis is required to make sure that the quality of water is in compliance with regulatory standards. What is this service?In our Water Testing Services, we analyze the drinking water, industrial waste water, ground or surface water sample on various standard parameters. The testing service determines the level of purity and pollution in the water sample. The water is sample tested for various harmful contaminants (both soluble and insoluble) in it. Surface or ground water is tested for bacteria and nitrates. For home water supplies, the water sample is tested for PH value, iron, dissolved solids, manganese, nitrates, alkalinity, dissolved solids, hardness. Why it is requiredIn industries, the poor quality of water can damage the machines and deteriorate the product standard. In the residential sector, the analysis of drinking water is very important as it can adversely affect your health and overall growth.

DESCRIPTION:
Microbial contaminants generally found in drinking water are Bacteria, Viruses, & Pathogenic Protozoa. Of these, significant causes of water borne diseases have been due to Bacteria such as Escherichia coli (E. coli), Salmonella, Vibrio cholerae, Shigella dysenteriae, Yersinia enterocolitica, Francisella tularensis, and Pseudomonas aeruginosa, and therefore essential to ensure Drinking Water is free of these pathogens, and are safe for Human Consumption. The methods generally employed for microbial testing are Plate Count (Growing Colonies on a Nutrient Media so that they can be counted), Membrane Filtration (Passing water through a sterile membrane filter with small pores, which can then be kept on agar plate or absorbent pad on which colonies can be counted), Flow Cytometry (a rapid reproducible microbial analysis used for operational assessment, root cause analysis, and disinfectant validation)
