How to determine the amount of Dissolved-Oxygen

How to determine the amount of Dissolved-Oxygen

Oxygen-Dissolved

Water in contact with a gas will usually have dissolved in it a small amount of that gas. The atmosphere for example, consists essentially of nitrogen and oxygen, and both are somewhat soluble in water. Nitrogen is an inert gas and of minor importance, but the control of dissolved oxygen in industrial waters is essential for efficient operation.

How to determine algae in given sample

How to determine algae in given sample

Algae are common and normal inhabitants of surface waters. They differ from bacteria and fungi  in that they have an internal green pigment called chlorophyll. Chlorophyll enables them, in the presence of sunlight, to combine water and carbon-di-oxide to form sugars or related substances with the release of oxygen by the process called photosynthesis. Recirculating cooling water systems normally are plagued with algae growth to a greater extent than once through systems.

How to determine the sulphate reducing bacteria in a sample

How to determine the sulphate reducing bacteria in a sample

Sulphate Reducing Bacteria 

Sulfate reducing bacteria (SRB) are anaerobic organisms which require an oxygen free environment for growth. They reduce sulfate to hydrogen sulfide.  They are responsible for the  foul hydrogen sulfide odors and are direct agents for corrosion. The hydrogen sulfide immediately reacts with metallic or dissolved iron to form black iron sulfide.

How to determine the total number of aerobic bacteria present in a sample

How to determine the total number of aerobic bacteria present in a sample

Total Viable Count (TVC)

Total viable count is a method to determine the total number of aerobic bacteria present in a particular water sample or deposit. This is an empirical measurement because occuring singly, in pairs, chains, clusters, or packets and no single growth medium or set of physical and chemical conditions can satisfy the physiological requirement of all bacteria in a water sample.
