There are several operating costs involved with the operation and treatment of wastewater. Operating costs are the charges related to the conservation, performing and covering of the factory. And, these costs can add up to 50 of the total periodic costs. It’s important to estimate the affiliated operating costs before getting a wastewater treatment factory. Then, we’ve calculated an approximate division of expenditure for your better understanding.

What are the different kind of operating costs involved in wastewater treatment?

Major factors that affect operation costs are

Size and capacity of the factory
Topography and geographical position of the factory
Characteristics of the wastewater generated
Technologies and the kind of treatment system
system of disposal used
Force of energy
Degree of robotization
Organisation and conservation of the factory

Workforce

The pool at the factory is one of the major factors that have a major influence on the operating costs. And, the number of working staff employed at the factory depends on the following

The scale of the factory
The treatment procedure and systems
The degree of robotization
The effectiveness of the labor force

Energy

The costs for energy cover nearly 10- 30 of the total operating costs. The following are the areas where energy gets consumed in a wastewater treatment factory and adds up to the total costs

Pumping Stations
defenses
Aerated Beach Traps
Primary Sedimentation Tanks
Aeration Tanks
Secondary Sedimentation Tanks
Thickener
Sludge Dewatering bias
Digestion

Disposal
Disposal is an important aspect when calculating the operating costs. It includes the costs involved in the disposal of sewage sludge, wireworks, beach and external waste.
These costs can differ between 15 and 50 of the total operating costs. Generally, they largely depend on

The size of the STP Plant

National regulations for the disposal of organic accoutrements like sewage sludge, etc.
Original conditions and request price conditions
Chemicals and Accoutrements Used
Chemicals and accoutrements take up to 5- 7 of the total operating costs. Their costs substantially depend on
The characteristics of the wastewater and its discharge
The named chemicals
Amounts kept in stock and copping deals
The request situation and the price structure of the chemicals

* Approximate Data

eclectic
Eclectic costs are the costs which largely depend on the type of wastewater treatment factory and can range between 5 and 15 of the total operating costs. These are

Pollution Charges
executive costs like insurances, office outfit etc.
Rents and vacancies
External costs for consultations, conservation workshop, laboratory analysis, etc.
