Waste water Related subject:
• Total suspended solids content (TSS);
• Chemical oxygen demand (COD);
GHG : greenhouse gas
GSV Report : Global security verification Report.

Chemical issue: EMISSION TO AIR
SOx (Sulfur Oxides), NOx (Nitrogen Oxides), Volatile Organic Compounds (VOCs), Ozone
Depleting Substances (ODSs), Toxic Air Pollutants (e.g. associated with solvents, adhesives), Lead, Carbon Monoxide, Water Vapor and Steam.

Starch : A complex carbohydrate found chiefly in seeds, fruits, tubers, roots and stem pith of plants, notably in corn, potatoes, wheat, and rice; an important foodstuff and used otherwise especially in adhesives and as fillers and stiffeners for paper and textiles.

COD :
In environmental chemistry, the chemical oxygen demand (COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre(mg/L). A COD test can be used to easily quantify the amount of organics in water. The most common application of COD is in quantifying the amount of oxidizable pollutants found in surface water (e.g. lakes and rivers) or wastewater. COD is useful in terms of water quality by providing a metric to determine the effect an effluent will have on the receiving body much like biochemical oxygen demand (BOD).

BOD :
Biochemical oxygen demand (BOD, also called biological oxygen demand) is the amount of dissolved oxygen needed (i.e., demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.

TDS
Thermal desorption spectroscopy (TDS), also known as temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. Many researchers prefer the name TPD because it is not a spectroscopic method.

TSS
Total suspended solids (TSS) is the dry-weight of particles trapped by a filter. It is a water quality parameter used for example to assess the quality of wastewater after treatment in a wastewater treatment plant. It is listed as a conventional pollutant in the U.S. Clean Water Act.[1]
TSS was previously called non-filterable residue (NFR), but was changed to TSS because of ambiguity in other scientific disciplines.

ATPDA :
Andean trade promotion and drug Eradication act.
CBTPA : Caribbean basin trade partnership act.

DHHC: Several proteins containing DHHC domains have been implicated in human disease.

DETOX : The hospital ward or clinic in which patients are detoxified

Work should be correct from the first time routinely
Change is treating as an opportunity
Work should be with enjoyment
Proper time maintain and on time reply
One rules for all no different rules will be allowed
Balance with changes – need adjust with current environment situation
