Industrial Blowers & Pumps for Sewage Treatment Plants

Blowers, pumps and aeration equipment for apartments, hospitals, hotels and IT parks. Sizing, supply, installation & AMC across Tamil Nadu.

Overview

How Sigma supports this industry

Apartments, hospitals, hotels, colleges and IT parks in Tamil Nadu must treat their sewage on site. The blower in your STP runs 24 hours a day, and when it stops the plant starts to smell within hours. Sigma Process Controls supplies STP blowers, sewage pumps and aeration equipment sized for your daily flow, with AMC support that keeps the plant running and compliant.

Right-sized for your plant capacity

STPs range from small residential plants to large municipal ones. A blower sized for the wrong capacity either wastes power or starves the bacteria. We size every blower from your design flow (KLD), BOD load and tank depth, and we always plan a standby unit so one machine can be serviced without stopping treatment.

Common STP problems we fix

Bad smell around the plant

usually low air supply. We check blower output and diffuser condition.

Blower noise disturbing residents

tri lobe blowers, acoustic hoods and correct silencers bring noise down.

Blower overheating or tripping

often a choked filter, worn lobes or wrong pressure setting.

Sewage pump clogging

we supply pumps with solids-handling impellers suited to raw sewage.

Treated water fails PCB norms

we review aeration capacity against the actual load.

Installation, commissioning and AMC for STPs

A well-chosen blower still fails early if it is installed badly. Our team guides foundation, alignment, belt tension, piping and electrical connections, then runs a trial to confirm air flow and pressure at the diffusers. After handover, our AMC covers oil changes, filter cleaning, belt and bearing checks and priority breakdown support, so your STP stays odour-free and within pollution control board norms.

FAQs

Frequently asked questions

Still have a question?

Talk to our team about your application.

What size blower does my apartment STP need?

It depends on daily sewage flow, BOD load and tank depth. Share your STP capacity in KLD and the tank drawings, and we’ll calculate the air flow and pressure required.

Twin lobe or tri lobe: which is better for an STP?

Both work well. Tri lobe blowers have lower pulsation and noise, which suits STPs near homes, hospitals and hotels. Twin lobe blowers are a proven, economical choice for most plants.

How often should an STP blower be serviced?

Check oil level and the air filter regularly, and plan a full service as per the manufacturer’s running-hour schedule. An AMC covers this for you.

Do you provide AMC for STP blowers and pumps?

Yes. Our AMC covers scheduled visits, spares and priority breakdown support across Tamil Nadu.
