Introduction
The treatment of municipal and industrial wastewater is vastly different!
Industrial wastewater contains different pollutants than municipal wastewater and is frequently more varied, concentrated, and hazardous. The nature of design, construction, and operational services, as well as procurement processes, are all different.
Why is wastewater characterization important?
The necessity for estimating wastewater characteristics arises from the need to treat wastewater with various characterizations using the appropriate technique following the construction of a sewer network in order to determine design parameters that represent site-specific conditions.
The majority of municipal wastewater is made up of water (99.9%), with very minor amounts of suspended and dissolved organic and inorganic particles.Carbohydrates, lignin, lipids, soaps, synthetic detergents, proteins and their decomposition products, as well as many natural and synthetic organic compounds from the process industries, are among the organic components found in sewage.
In addition to inorganic compounds from home and industrial sources, municipal wastewater contains a number of potentially harmful elements such as chromium, copper, lead, mercury, arsenic, cadmium, zinc, and others. Even if poisonous elements are not present at proportions that are harmful to people, they may be phytotoxic, limiting their usage in agriculture. However, pathogenic micro and macro-organisms are the contaminants of greatest concern from the standpoint of health, which is a critical factor in agricultural wastewater utilization.
How to estimate wastewater characteristics?
For optimal treatment system design, accurate characterisation of raw wastewater, including daily volumes, rates of flow, and associated pollutant load, is crucial.
An accurate assessment of the wastewater to be treated is required for determining treatment system performance requirements, selecting appropriate treatment methods, designing the treatment system, and running the system. There are two categories of onsite systems:
- Residential and Commercial;
- Non-residential or Industrial.
1: Residential dwellings include single-family households, condominiums, apartment buildings, multifamily households, cottages, and resort residences. Individual waste streams generated by water-using activities from a range of plumbing fixtures and appliances make up the discharges from these residences.
2: Non-residential wastewater includes a wide range of institutional (e.g., schools), commercial (e.g., restaurants), and industrial establishments and facilities. Some non-residential establishments generate wastewater in the same way as residential dwellings do. Non-residential wastewater, on the other hand, is frequently quite different from that of residential units, and therefore should be properly defined before an Onsite Wastewater Treatment System (OWTS) is designed.
The properties of wastewater generated in some non-residential establishments may make it impossible to employ traditional systems without modifying wastewater loadings through enhanced pretreatment or accommodating elevated organic loads by expanding the subsurface wastewater infiltration system.
Cause of diversity in non-residential effluent
Subtle and often intangible effects affect a huge number of seemingly comparable non-residential facilities, causing significant diversity in effluent characteristics. Popularity, pricing, cuisine, and location, for example, can cause significant differences in wastewater flow and quality between restaurants.
As a result, the wastewater to be treated at existing facilities should be described by metering and sampling the current wastewater stream. However, features of non-residential wastewaters should be approximated based on accessible data for many existing developments and practically any proposed development.
