Key features
⚡
Power saving
claims up to 70% lower power consumption versus conventional STPs; actual savings vary by design and operation.
🔇
Noise & odour
Enclosed system and low-noise blower design are described to help control odour and sound.
No Operator Required
Designed for automated operation, reducing the need for a dedicated full-time operator. Actual supervision and maintenance requirements depend on plant configuration, site conditions and local regulations.
📐
Space saving
Compact packaged design can require up to 60% less installation space than a conventional STP, as stated in the brochure. Actual space savings depend on plant capacity, layout and site conditions.
Manufacturing excellence

The modern manufacturing process with checks at each stage to support consistent quality, precision and reliability.
①
FRP Lamination
Controlled lamination process for strength and corrosion resistance.
②
Assembly & Fittings
Integration of essential mechanical components with quality checks.
③
Final Assembly
Assembly with accessories and finishing as per design standards.
④
Quality Testing
Dimensional and performance checks before dispatch.
Complete process control
From raw material to final product.
Skilled team & modern infrastructure
The manufacturing facility in Ghaziabad and describes a skilled team and modern infrastructure.
Process description
How the packaged STP works
The process stages below follow the treatment sequence. Final process design should be confirmed for the specific plant model and wastewater.
01
Solid Separation & Settling
Incoming domestic sewage enters the first chamber. Heavier suspended solids settle by gravity and are retained as sludge, reducing solids entering biological stages.
02
De-nitrification Chamber
Under low-oxygen conditions, organic material is decomposed and recirculated nitrate/nitrite can be converted into nitrogen gas, helping reduce total nitrogen.
03
Aerobic Chamber
Air supplied through the aeration system supports aerobic microorganisms that break down organic material, reducing BOD and other pollutants while producing biological sludge.
04
Clarifier & Recirculation
Suspended biological solids settle. Settled sludge containing active microorganisms is recirculated to maintain biomass and support treatment efficiency.
05
Chlorination Chamber
A controlled chlorine dose disinfects the water. Reuse or discharge depends on achieved quality, applicable standards and project requirements.

Design basis
water-quality parameters
The following are the inlet and outlet figures . These are design-basis figures, not a guarantee for every project; actual performance must be confirmed by design conditions and testing.
| Parameter | Inlet (Raw Sewage) | Standard Model Outlet | Advanced Model Outlet |
|---|---|---|---|
| pH | 6–8 | 6–8 | 6–8 |
| COD (mg/L) | 450 | 50 | < 50 |
| BOD (mg/L) | 300 | 20 | < 10 |
| TSS / SS (mg/L) | 240 | 30 | < 20 |
| Oil & Grease (mg/L) | 40 | 10 | < 10 |
Important: the outlet quality achievable at site depends on influent characteristics, hydraulic/organic loading, operation, maintenance and the final plant configuration. Confirm compliance requirements before specifying reuse or discharge.
Running cost comparison
Lower power consumption for higher savings
The values below reproduce the annual running-cost comparison. Treat them estimates, not a universal cost quotation.
Annual running cost — ₹ lakh / year
Bars compare the conventional-STP and Kobuta ECOTREAT estimates for each capacity.
example · 50 KLD plant
₹5.9 lakh/yearEstimated annual saving , comparing ₹6.5 lakh/year for a conventional STP with ₹0.6 lakh/year for Kobuta ECOTREAT. Actual costs vary with energy tariffs, operating hours, loading and maintenance.
