| In the current scenario, sewage is an abundantly
available resource that can fill the gap between water availability
and demand. Though most of the organic compounds found in sewage can be treated readily, there are constituents
- such as organic nitrogen - that are not easily amenable to conventional treatment methods.
Sewage recycling based on photochemical oxidation treats the sewage to such purity levels, where the treated wastewater can easily substitute fresh water.
The advantages of sewage recycling using photochemical oxidation over conventional processes are,
|Compact skid mounted systems – do not occupy much space.|
|Can be operated in batch mode.|
|Low energy requirement.|
|Modular Systems – ease of upgradation.|
|No need for extensive civil work.|
|Process does not generate its own effluent.|
|The treated effluent quality will be consistent.|
|Additional advantage of a disinfected effluent available for reuse.|
|COOLANT RECOVERY SYSTEM|
The birth of “cutting fluids” or coolant revolutionized the operations of engineering industries - but have equally created a negative impact on the environment – Coolants
are highly non bio-degradable.|
Upon continuous usage in the machine, soluble cutting oils need replacement, primarily due to offensive odor (due to biological degradation) and accumulation of different types of particulate matter, each having a deterrent effect on the coolant performance and life.
Coolant recovery system has been designed to eliminate the contaminants in coolant - which are mainly tramp oil & bacteria - without altering the properties of the original emulsion. This enables increase in coolant cycle times, thereby reducing both procurement of fresh oil as well as frequency of discharge.
