UV Water Treatment in Anand–Nadiad: Amul's Milk-Grade Water & the Mahi River Zone

Anand — "The Milk Capital of India" — is the birthplace of India's White Revolution and the home of Amul (the Anand Milk Union Limited), which Dr. Verghese Kurien built into India's most successful cooperative brand. The district of Anand is the original collection zone of Gujarat's milk cooperative model: farmer-owned village-level dairy cooperatives feeding into district unions (AMUL) that process and market under the GCMMF national umbrella. The Anand model has been replicated across India, but the Anand-Kheda district remains the geographic and spiritual heart of India's cooperative dairy movement.

Beyond dairy, Anand and Nadiad have developed into significant educational (Anand Agricultural University, Sardar Vallabhbhai Patel National Police Academy), pharmaceutical, and food processing hubs in central Gujarat. The Mahi River supply — shared with Vadodara's agricultural and residential needs — provides a surface water source that is treated by GWSSB and municipal corporations before distribution.

Petlad / Borsad (satellite towns)	GWSSB supply + borewell	Agricultural towns; dairy cooperative collection; borewell TDS 500–1,200 mg/L in southern Anand district	NABL test first; RO + UV for high-TDS borewell; post-tank UV for GWSSB supply

UV for AMUL and Gujarat's Dairy Cooperative Sector

GCMMF (Amul's parent cooperative federation) processes approximately 26–30 million litres of milk daily at its processing facilities across Gujarat — the Anand milk processing plant, Anand ice cream plant, Gandhinagar cheese plant, and various district dairy plants in NDDB's cooperative network. UV water treatment in dairy processing:

Why UV — not chlorine — in dairy processing water: Dairy product quality is acutely sensitive to chlorine residual in water used in milk contact applications (equipment cleaning, CIP final rinse, condensate make-up water). Even trace chlorine (0.1–0.2 mg/L) in dairy CIP rinse water can cause chlorophenol off-flavours in milk and milk products — a disaster for quality-conscious brands like Amul. UV at 40 mJ/cm² provides the microbiological safety required for FSSAI food contact water compliance without any chemical residual in the product-contact water.

FSSAI export compliance: Amul's cheese, butter, and anhydrous milk fat (AMF) exports to the EU and the USA are governed by EU Regulation 853/2004 and US FDA's Grade A pasteurised milk ordinance (PMO). Both require dairy plant water quality documentation — UV system commissioning reports and intensity monitoring logs form part of the plant's water safety documentation reviewed during EU and US Dairy Grading Branch inspections of Indian dairy exporters.

Application	Flow Rate	UV Dose	Notes

AMUL dairy plant food contact water	5–30 m³/h	40 mJ/cm²	FSSAI food contact water; no chlorine in dairy product contact; 316L SS food-grade body; EU export audit
Village dairy cooperative collection point	1–3 m³/h	40 mJ/cm²	Village dairy BMC cleaning water UV; FSSAI milk handling water; compact UV for rural cooperative
Pharma purified water (Anand GIDC)	2–10 m³/h	80 mJ/cm²	185 nm + 254 nm; Schedule M 2025 IQ/OQ/PQ; GPCB documentation
GMERS Medical College hospital (Nadiad)	5–20 m³/h	40–80 mJ/cm²	NABH hospital water safety; dialysis UV; ICU 80 mJ/cm²
STP outlet — 300 KLD (Anand residential)	20–30 m³/h	40 mJ/cm²	Philips TUV 95W; GPCB consent documentation; Mahi River basin compliance

Does Amul and the cooperative dairy sector use UV for all water in the plant?

In a well-run dairy plant meeting FSSAI and EU/US dairy standards, UV should be installed on the water supply for all product-contact applications: CIP final rinse water supply, boiler feed water (steam used for sterilisation), ice cream hardening tunnel air wash water, packaging machine wash water, and container rinse water. UV is not typically needed for: cooling tower water (chlorine-based biocides are acceptable for non-product-contact cooling water in dairy plants), floor washing water, or non-contact cleaning applications.

The practical implementation in a large dairy plant like Amul Anand: a main UV system at the plant water supply header (treating all incoming water from the GWSSB supply or borewell backup) followed by a UV polishing unit specifically on the CIP final rinse water circuit (because the CIP circuit has specific microbiological sensitivity). For smaller village-level dairy cooperative collection centres (BMC — Bulk Milk Cooler centres): a single compact UV system at 1–3 m³/h on the BMC cleaning water supply covers all FSSAI-required food contact water applications. Alpha UV System supplies dairy-grade 316L stainless steel UV reactors specifically for the dairy sector — suitable for Amul and affiliated cooperative plants and for private dairy processors in the Anand-Nadiad district.
