Description
Introduction to 75 KLD Sewage Treatment Plant
A 75 KLD Sewage Treatment Plant (STP) is a wastewater treatment system designed to treat approximately 75,000 litres of domestic sewage per day under its specified design conditions. It is suitable for large residential societies, apartment complexes, hotels, resorts, hospitals, educational institutions, commercial buildings, offices, townships and other facilities generating substantial quantities of domestic wastewater.
As urban development expands, efficient wastewater treatment has become an essential part of responsible water management. Untreated sewage can cause unpleasant odours, sanitation problems and environmental pollution while affecting nearby land and water resources.
A properly designed 75 KLD STP plant provides a systematic process for collecting, treating and managing domestic sewage. Depending on the selected technology and required treated-water quality, the treated water can potentially be reused for applications such as gardening, landscaping, toilet flushing and floor cleaning.
V AQUA WATER TREATMENT COMPANY provides sewage and wastewater treatment solutions designed according to project capacity, wastewater characteristics, site conditions, available space and treated-water reuse requirements.
What Does 75 KLD Mean in an STP?
KLD means Kilolitres per Day.
Therefore:
- 1 KLD = 1,000 litres per day
- 75 KLD = 75,000 litres per day
A 75 KLD sewage treatment plant is designed for a nominal treatment capacity of approximately 75,000 litres of sewage per day.
The actual design of the plant should consider more than the daily flow. Important design factors include:
- Number of users
- Average water consumption
- Sewage generation rate
- Peak flow
- Wastewater characteristics
- Hydraulic retention time
- Required treated-water quality
- Water-reuse requirements
- Future expansion
- Available installation area
A properly engineered system helps ensure that the plant can handle normal variations in wastewater flow and loading.
Why Is a 75 KLD Sewage Treatment Plant Required?
Domestic sewage contains biodegradable organic matter, suspended solids, nutrients, microorganisms and other contaminants. Discharging untreated sewage can negatively affect the surrounding environment and create sanitation concerns.
A 75 KLD sewage treatment plant manufacturer designs treatment systems to reduce these pollutants using physical, biological and, where required, tertiary treatment processes.
The major reasons for installing a 75 KLD STP include:
- Effective domestic wastewater treatment
- Environmental protection
- Better sanitation
- Reduction of organic pollution
- Reduction of suspended solids
- Support for treated-water reuse
- Reduction in freshwater consumption
- Improved wastewater management
- Support for applicable project requirements
For large residential, commercial and institutional developments, on-site sewage treatment can be an important component of an integrated water-management strategy.
How Does a 75 KLD STP Plant Work?
The exact process depends on the selected technology and wastewater characteristics. A typical 75 KLD sewage treatment system may include several treatment stages.
1. Screening and Preliminary Treatment
Raw sewage first passes through a screening system designed to remove larger solid materials such as:
- Plastic
- Paper
- Cloth
- Packaging materials
- Other floating debris
This preliminary treatment helps protect pumps, valves, pipelines and biological treatment equipment.
2. Equalization Tank
An equalization tank helps balance variations in sewage flow and pollutant loading.
Wastewater generation changes throughout the day. Equalization can therefore provide a more consistent flow to downstream treatment stages and improve process stability.
3. Primary Treatment
Primary treatment is used to separate settleable solids and heavier suspended materials from the wastewater.
Depending on the selected design, this stage can include settling arrangements or other primary-treatment equipment.
4. Biological Treatment
Biological treatment is a major stage in domestic sewage treatment.
Microorganisms break down biodegradable organic matter present in the wastewater.
Common biological treatment technologies include:
- MBBR
- SBR
- MBR
- Activated Sludge Process
- Extended Aeration
- Other customized biological processes
The appropriate process should be selected according to wastewater characteristics, available space, treated-water requirements and operating preferences.
5. Secondary Clarification
Following biological treatment, clarification may be used to separate biological solids from the treated wastewater.
Depending on the treatment process, a portion of the settled sludge may be returned to the biological stage while excess sludge is removed for appropriate management.
6. Tertiary Filtration
Where additional polishing is required, tertiary treatment can be incorporated.
Possible filtration systems include:
- Pressure Sand Filter
- Activated Carbon Filter
- Micron Filter
- Ultrafiltration
- Other polishing systems
The final configuration should be based on the desired treated-water quality and intended reuse.
7. Disinfection
Disinfection helps reduce microbial contamination in the treated water.
Possible systems include:
- Chlorination
- Sodium hypochlorite dosing
- UV disinfection
The appropriate disinfection method depends on the application and required water quality.
8. Treated-Water Storage and Reuse
After treatment and disinfection, the treated water can be transferred to a storage tank.
Depending on quality and applicable requirements, it can potentially be reused for:
- Gardening
- Landscaping
- Toilet flushing
- Floor washing
- Road cleaning
- Other suitable non-potable applications
