Industrial Blowers & Pumps for Tannery CETPs

Blowers, pumps and aeration equipment for tanneries in Ranipet, Ambur, Vaniyambadi and Dindigul. Sizing, supply, installation & AMC across Tamil Nadu.

Overview

How Sigma supports this industry

Tannery effluent is among the hardest wastewater to treat. It carries chromium, sulphides, salts, lime, hair and fleshings, often at high strength. Tamil Nadu’s leather clusters in Ranipet, Ambur, Vaniyambadi, Pernambut and Dindigul depend on common effluent treatment plants (CETPs) that must run without a break. Sigma Process Controls supplies heavy-duty aeration blowers, solids-handling pumps and process equipment built for this load.

Equipment for tannery effluent treatment

Stage	Equipment	Purpose
Screening & collection sump	Submersible sewage pump	Lifts effluent with hair, fleshings and grit
Equalisation & sulphide oxidation	Twin lobe Roots blower, jet aerator	Mixes effluent and oxidises sulphides
Chrome recovery / primary treatment	Transfer pumps, valves	Moves effluent through dosing and clarifiers
Biological (extended aeration)	Twin lobe / tri lobe Roots blower	High-volume air for strong organic load
Sludge handling	Sewage pump	Transfers heavy sludge to drying beds or filter press
RO & reject (ZLD)	Vertical / horizontal multistage pump	High-pressure RO feed and reject transfer

Why tannery CETPs need the right equipment

Corrosion

Salt and sulphide-rich effluent attacks standard materials. We match pump MOC and seals to the effluent.

Solids and fibres

Pumps need open or vortex impellers that pass solids without choking.

Very high air demand

Strong effluent needs large, reliable aeration capacity with standby.

Compliance pressure

under ZLD rules, a stopped ETP can stop the factory too. Keep spares and an AMC in place.

FAQs

Frequently asked questions

Still have a question?

Talk to our team about your application.

What blower is used for tannery CETP aeration?

Twin lobe or tri lobe Roots blowers are the usual choice for their steady, oil-free air at diffuser pressure. We size them for your effluent strength and tank depth.

Which pump handles tannery effluent with solids?

A submersible sewage pump with a solids-handling impeller is suited to raw tannery effluent. Pump material is chosen for the effluent’s salt and sulphide content.

Can you upgrade an existing CETP’s aeration system?

Yes. We assess current blower output against the actual load and recommend replacement or added capacity.
