UV Water Treatment Systems in Aligarh — Complete Buyer's Guide 2026

Aligarh — famous for the Aligarh lock (Aligarh produces 70%+ of India's security padlocks and door hardware) and Aligarh Muslim University (one of India's oldest and most respected central universities, founded 1875) — is a mid-sized UP city with a distinct industrial and educational character. The lock manufacturing industry — concentrated in the Aligarh City's Jamalpur area and distributed across small workshops throughout the city — produces millions of padlocks annually ranging from basic iron padlocks to high-security brass and stainless steel locks for export.

Aligarh's Upper Ganga Canal supply — from the canal that carries Ganga water from Haridwar across western UP — provides a reasonable treated water base. However, the canal water quality is influenced by agricultural runoff from the intensively cultivated western UP plains, and post-treatment bacterial contamination in Aligarh's extreme summer heat is the primary residential water safety concern.

UV for Aligarh's Lock and Hardware Manufacturing Industry

Aligarh's lock manufacturing sector — from small-scale family workshops producing a few hundred locks per day to medium-scale factories producing hundreds of thousands of locks monthly for export to the USA, Europe, and Southeast Asia — uses water in electroplating, polishing, and assembly washing operations. The UV relevance in lock manufacturing:

Electroplating rinse water: Chrome plating (on padlock bodies and shackles for corrosion resistance) and nickel plating (for decorative finish) are common in Aligarh lock manufacturing. Electroplating process includes multiple rinse stages — chromic acid rinse, nickel strike rinse, final rinse — where UPPCB heavy metal effluent standards apply. UV on the final rinse water prevents bacterial contamination that can cause spotting on freshly plated surfaces. More importantly, the electroplating ETP final effluent requires UV as a coliform reduction step before UPPCB-regulated discharge into the Kali West river system.

Worker potable water: Lock manufacturing workshops — many of which are small-scale with hundreds of workers — require potable water for the workforce. Workshops in the Jamalpur industrial area often use borewell water (TDS 300–600 mg/L in most Aligarh zones) — UV at the workshop water outlet ensures worker drinking water safety.

Application	Flow Rate	UV Dose	Notes
Residential apartment (Ramghat Road / Marris Rd)	1–3 m³/h	40 mJ/cm²	Post-overhead-tank UV; 5 µm pre-filter; May–June extreme heat critical
AMU campus hostel water	5–30 m³/h	40 mJ/cm²	Campus supply UV; FSSAI hostel kitchen compliance; 30,000 student water safety
Lock manufacturing worker potable water	1–3 m³/h	40 mJ/cm²	Workshop borewell UV; worker safety; UPPCB Factories Act water standard
Electroplating ETP final effluent (Jamalpur)	5–20 m³/h	40 mJ/cm²	UPPCB coliform limit; Kali West river discharge; heavy metal ETP post-treatment UV
STP outlet — 300 KLD (Aligarh residential)	20–30 m³/h	40 mJ/cm²	Philips TUV 95W; UPPCB/NMCG consent documentation; Kali-Yamuna basin compliance

Is Aligarh's Kali West River under NGT monitoring like the Ganga tributaries?

Yes — the Kali River (Kali West, not to be confused with the Kali East in eastern UP) flows through Aligarh district before joining the Yamuna near Aligarh. The Kali West receives industrial and municipal effluent from Aligarh's lock manufacturing, textile dyeing, and food processing industries, and has been flagged by the NGT and UPPCB as a severely polluted river segment. As a Yamuna tributary, the Kali West falls under the NMCG (National Mission for Clean Ganga) monitoring framework — the Supreme Court's Yamuna action plan includes Kali West pollution abatement as a component of the broader Yamuna cleanup.

The practical implications for Aligarh industries and residential complexes discharging into the Kali West: UPPCB consent conditions require STP/ETP UV before discharge; NMCG online monitoring tracks effluent quality in real time; and the NGT has issued show-cause notices to Aligarh Municipal Corporation and industries for Kali West pollution. Residential complexes in Aligarh generating sewage above 50 KLD per day must have UPPCB-consented STP with UV at 40 mJ/cm² on the final effluent.
