Practically it is difficult to determine a complete analysis of all parameters in the wastewater.
For the purposes of design and operation of wastewater treatment plants, some of the required parameters in classifying the waste water, as follows:
A. Solid Substance (Total Solid)
B. Organic Substances (Organic Matter)
C. Nutrient (Nitrogen and Phospate)
D. Pathogens
E. Industrial Wastewater
Solids consist of:
TDS (Total Dissolved Solid).
TSS (Total Suspended Solid).
For example:
Waste water = 700 mg / l (total solid), comprising:
250 mg / l = suspended solid
450 mg / l = filterable Solid:
50 mg / l colloidal
400 mg / l Dissolved Solid
Organic matter consists of:
Carbohydrates with a composition of C, H, O (30-50%)
Fats / Oils with the composition C, H, N, O (10%)
Protein composition of C, H, O, N, S, P (40-60%)
The parameters are always in use in measuring levels of organic substances contained in waste water is "oxygen demand" with the measurement of BOD or COD (permanganate or dichromate Mn04 = CR ² 07 ²).
