Description
7 KLD ETP Manufacturer in India – High-Efficiency Effluent Treatment System for Continuous Industrial Operations
A 7 KLD ETP (Effluent Treatment Plant) is a medium-capacity industrial wastewater purification system specifically engineered to treat 7000 liters of effluent per day. It is suitable for industries that produce a moderate but consistent flow of polluted water, which requires structured purification before safe disposal or reuse. This capacity has shown significant demand growth across India, especially in MSME industries, where wastewater output is consistent and regulatory compliance is mandatory.
V AQUA Water Treatment Company, recognized nationwide for its engineering excellence and superior water treatment systems, is among the most trusted 7 KLD ETP manufacturers in India, offering high-performance, low-maintenance, and technologically advanced effluent treatment systems designed for long-term durability and environmental protection.
This complete 2000-word article provides a detailed overview of the technology, application, mechanism, advantages, components, engineering design, industry benefits & regulatory compliance related to a 7 KLD ETP Plant in India, along with the role of V AQUA as a leading manufacturer.
Understanding a 7 KLD Effluent Treatment Plant
A 7 KLD ETP is a specially designed wastewater purification facility used to remove harmful contaminants such as:
- Suspended solids
- Organic waste
- toxic metals
- oils & grease
- high TSS/TDS
- dyes & color impurities
- chemical residues
- industrial surfactants
- odor compounds
- biological contaminants
The system ensures that discharged water meets national discharge norms as governed by the Central Pollution Control Board (CPCB).
In several sectors, installing an ETP has become an environmental obligation, not a preference.
Industries That Commonly Use 7 KLD ETP Systems
7 KLD suits medium-scale industries such as:
- Food processing industries
- Chemical mixing units
- Pharma production units
- Vehicle servicing facilities
- Automobile assembly shops
- Metal cleaning workshops
- Textile washing units
- Garment processing
- Hotel laundry and washing plants
- Soap & detergent manufacturing
- Industrial canteen units
- Plastic granule washing plants
- Dairy processing lines
- Paint & polishing units
These industries generate wastewater with compound impurities that must be neutralized before environmental discharge.
Why 7 KLD ETP Capacity Is Increasing in India
The 7 KLD category is rising in demand due to its unique economic and operational advantages:
✔ Right-Sized capacity
Large enough for serious industrial discharge
Small enough for affordable operating cost
✔ Ideal for medium-business owners
Matches ongoing production flow
✔ Fits compliance category
Recognized by all Pollution Boards
✔ No complex infrastructure requirement
✔ Affordable civil footprint requirement
✔ Scalable up to 10–15 KLD in future
How a 7 KLD ETP Works – Step-By-Step Treatment Cycle
A standard process route involves multiple purification stages:
1. Pre-treatment
- Effluent collection
- Screening
- Oil removal
- Equalization
- Chemical conditioning
2. Primary Treatment
- Coagulation
- Flocculation
- Primary settling
- Sludge removal
3. Biological Treatment
Based on industry type:
- Activated Sludge Process
- MBBR Biological Reactor
- SBR System
- Biodegradation
- Aeration reservoir
Removes high BOD and COD.
4. Secondary Clarification
- Biomass settling
- Sludge thickening
- Clarifier unit
5. Tertiary Filtration
- PSF
- ACF
- Bag / Cartridge filters
- Disinfecting & polishing stage
After this phase, water becomes suitable for reuse or permissible discharge.
