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

FRP built for a longer life.

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.

ParameterInlet (Raw Sewage)Standard Model OutletAdvanced Model Outlet
pH6–86–86–8
COD (mg/L)45050< 50
BOD (mg/L)30020< 10
TSS / SS (mg/L)24030< 20
Oil & Grease (mg/L)4010< 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.
