What ZLD Technologies does

ZLD Technologies Private Limited is an Indian engineering organization headquartered in Thane, Maharashtra with a secondary office in Ahmedabad, Gujarat, that designs, manufactures, supplies, and commissions industrial water treatment and process engineering systems. Its core technology portfolio spans seven categories: wastewater treatment (Effluent Treatment Plants and Membrane Bio Reactors), membrane filtration (Reverse Osmosis, Ultrafiltration, Nanofiltration, Microfiltration), evaporation technologies (Multi Effect Evaporator, Mechanical Vapor Recompression, Multi Effect Distillation, Dryers and Crystallizers), industrial vacuum systems (liquid ring vacuum pumps, steam jet ejectors, thermo-compressors per HEI standards), heat and mass transfer-based projects (solvent, caustic, salt, and metals recovery plants; chloro-alkali plants; chemical separation), and engineering equipment (heat exchangers, filter presses, hydrocyclones, spray dryers, vapor-liquid separators, decarbonators).

The company serves industrial manufacturing facilities, chemical and petrochemical plants, water-intensive industries (food, textile, pharmaceutical, biotechnology), and OEMs and project management companies requiring ZLD compliance, desalination, chemical recovery, and energy-efficient evaporation. Revenue is generated through three streams: one-time engineering projects and equipment supply (turnkey installations), professional services such as feasibility studies, basic and detailed engineering, energy audits, and plant upgrades, and recurring Operations & Maintenance contracts and Annual Maintenance Contracts on the installed base.

Go-to-market is direct enterprise field sales within India; pricing is quote-based and project-specific. The company has no disclosed funding history, no headcount figures, no patents, no certifications, no named customers, and no management team disclosure beyond Vaijnath Tandle as a primary contact at the Thane headquarters. The company's articulated ambition is to become the leading technology provider globally, although current operations are confined to India.
