ETP Manufacturer & Supplier — Mysore (Mysuru), Karnataka
Turnkey effluent treatment plants for Mysore's silk dyeing, food processing, pharmaceutical, and precision engineering industries — KSPCB-compliant ETP and ZLD systems across Belagola, Hebbal, and KIADB industrial areas
Industry Overview
ETP Manufacturer & Supplier — Mysore (Mysuru), Karnataka
Mysuru (officially renamed from Mysore in 2014) is Karnataka's second-largest city and one of South India's most well-established industrial centres. Key industrial areas include Belagola Industrial Area (BIA) and Hebbal Industrial Area (HIA), along with several KIADB (Karnataka Industrial Areas Development Board) notified zones. The city's industrial profile is distinctively diverse: Mysore silk — a GI-tagged product — supports a substantial cluster of silk weavers, power-loom units, and dyeing operations; food and beverage processing (historically tied to Mysore's edible oil heritage, along with dairy, confectionery, and beverages) forms a significant industrial base; pharmaceuticals, precision engineering, and defence/aerospace manufacturing (BEML, Kirloskar Electric, and their supply chains) contribute high-value manufacturing; and traditional sandalwood and incense manufacturing adds a culturally specific industrial segment.
Karnataka State Pollution Control Board (KSPCB) exercises jurisdiction over Mysore's industrial units, enforcing CPCB General Standards with specific attention to textile dyeing units' colour compliance. Mysore silk dyeing — involving natural dyes, synthetic dyes, and mordants — generates effluent with high colour, elevated TDS from dye assistants, and traces of heavy metals from mordants. KSPCB specifically monitors colour in textile effluent and requires that treated effluent be visually colourless before discharge. Beyond colour, the Cauvery river basin provides Mysore's water supply — the KRS (Krishnarajasagara) dam makes Mysore comparatively water-adequate relative to drier Deccan cities, but responsible wastewater management and ETP compliance remain non-negotiable regulatory obligations for all discharge-category industries.
Spans Envirotech delivers ETP EPC projects across South India and pan-India. Our capability in textile colour removal — ozonation, activated carbon, advanced coagulation — combined with food processing FOG treatment expertise (DAF-based systems for dairy and edible oil effluent) and pharmaceutical wastewater treatment experience, positions us well for Mysore's multi-sector industrial base. We provide full turnkey services: KSPCB consent support, process design, equipment supply, civil coordination, commissioning, and post-commissioning AMC.
Industry Challenges
Key Environmental Challenges
Silk Dyeing Colour Removal — KSPCB Compliance
Mysore silk dyeing generates effluent with intense colour from natural and synthetic dyes, high TDS from mordants (alum, iron, chrome mordants) and dye bath assistants, and BOD from residual organics. KSPCB specifically requires treated textile effluent to be visually colourless — standard biological treatment alone cannot achieve this. Targeted colour removal technologies (ozonation, activated carbon polishing, or advanced coagulation with PAC) are required upstream or downstream of biological treatment.
High-FOG Food Processing Effluent — Dairy and Edible Oil
Mysore's food processing sector — dairy units, edible oil processors, confectionery manufacturers — generates high-FOG (fat, oil, grease) effluent alongside high BOD and COD loads. Conventional biological treatment is severely impaired if FOG is not removed first. Dissolved Air Flotation (DAF) is the primary required pre-treatment for food processing ETPs in Mysore, followed by MBBR or activated sludge biological treatment for BOD polishing to KSPCB standards.
Mordant and Heavy Metal Traces in Silk Dyeing Effluent
Traditional Mysore silk dyeing uses metallic mordants (alum, iron sulphate, chrome mordant) to fix natural dyes on silk fibre. These contribute trace heavy metals (chromium, iron) and elevated sulphate to the effluent stream. KSPCB standards include limits on chromium and other heavy metals. ETPs for silk dyeing units must incorporate physio-chemical treatment (precipitation, coagulation) alongside colour removal and biological polishing.
Pharmaceutical and Precision Engineering Effluent
Mysore's pharmaceutical manufacturing units generate high-COD effluent with API residues and solvent traces requiring physio-chemical pre-treatment before biological treatment. Precision engineering units (defence suppliers, BEML ancillaries) generate metalworking fluid emulsions, cutting oil, and surface treatment effluent with mixed inorganic and organic contaminants. Both require sector-specific ETP configurations beyond a standard generic design.
Multiple Small Silk Dyeing Units with Limited Capital
Mysore's silk dyeing cluster includes numerous small and traditional dyeing units with limited capital for ETP investment. Right-sized, cost-effective ETPs — designed for 10–100 KLD dyeing operations with colour removal — rather than oversized installations, are essential for the cluster's compliance. Package-format colour-removal ETPs and common effluent treatment plant (CETP) options are relevant for small dyeing units.
Sandalwood and Incense Manufacturing Effluent
Mysore's traditional sandalwood products and incense (agarbatti) manufacturing generates process wastewater with high organic load from sandalwood dust slurries, fragrance compound residues, and bamboo/charcoal processing. While volumes are typically lower than textile or food processing units, the effluent's high BOD and unusual organic chemistry requires careful treatment system design and KSPCB consent documentation.
Our Solutions
Tailored Wastewater Treatment Solutions
Silk Dyeing ETP with Colour Removal — KSPCB Compliant
Complete ETPs for Mysore silk dyeing units — advanced colour removal (ozonation, activated carbon adsorption, or PAC coagulation), physio-chemical treatment for mordant heavy metal removal, biological treatment (MBBR) for BOD reduction, and final polishing. Designed to achieve KSPCB's colour compliance requirement of visually colourless discharge. Sized for the batch-nature of dyeing operations with appropriate equalisation.
Food Processing ETP — DAF and Biological Treatment
ETPs for dairy, edible oil, and confectionery units in Mysore — DAF for primary FOG removal, MBBR biological treatment for BOD and COD reduction, secondary clarification, and sludge dewatering. Designed for the high organic loads typical of Mysore's food processing sector, with KSPCB CTO documentation support and commissioning to consent parameters.
Pharmaceutical Wastewater ETP — COD and API Treatment
Pharmaceutical-sector ETPs for Mysore's pharma manufacturing units — physio-chemical pre-treatment (Fenton oxidation, stripping) for COD reduction and solvent residue management, followed by MBBR or SBR biological treatment and activated carbon polishing for final effluent quality. KSPCB CTO conditions specific to pharmaceutical sector effluent standards.
Engineering and Metalworking ETP — Surface Treatment
ETPs for precision engineering and defence sector manufacturers in Mysore — DAF for cutting oil emulsion breaking, heavy metal precipitation for chromium and zinc from surface treatment, neutralisation, and biological polishing. Turnkey design to KSPCB standards for metal-finishing and engineering manufacturing effluent.
Wastewater Colour Polishing — Upgrade for Existing ETPs
For Mysore units with existing ETPs that do not achieve KSPCB's colour compliance requirement, we provide targeted colour-removal upgrades — ozone generators, activated carbon contactors, or PAC dosing systems — as add-on tertiary treatment stages. Retrofits designed to fit existing tank infrastructure and process flow where possible.
STP for Institutions and Hospitality
Compact MBBR and MBR-based STPs for Mysore's educational institutions, hotels, hospitals, and residential townships — KSPCB-compliant treated water reuse for landscaping and flushing. Mysore's tourism industry creates demand for reliable, low-footprint STPs in heritage hotel and resort properties.
