Overview
Specialised O&M Support for Zero Liquid Discharge Plants
ZLD plants involve multiple treatment stages — primary treatment, biological treatment, tertiary treatment, UF, RO, MEE, MVR, ATFD, crystallization, sludge handling, chemical dosing, and condensate polishing. Operating them requires process understanding, not only manpower. Terraquaer provides technical O&M support for ZLD systems to improve reliability, reduce downtime, and maintain compliance.
ZLD O&M Scope
Feed wastewater monitoring, pre-treatment operation, biological treatment monitoring, UF and RO operation, membrane cleaning support, MEE, MVR and ATFD operation support, condensate quality monitoring, salt and sludge handling coordination, chemical dosing optimisation, scaling and fouling control, preventive maintenance of pumps, membranes, evaporators and dryers, daily log sheets and performance reports, and troubleshooting for non-compliance, low recovery, scaling, foaming, choking, and high power consumption.
Suitable Industries
Textile and dyeing, pharma and API, chemical and specialty chemical, food and beverage, automobile, metal finishing, semiconductor, common effluent treatment plants, industrial parks, and all high-TDS wastewater-generating industries.
Terraquaer Advantage in ZLD O&M
Our team brings experience across ETP, RO, UF, MBR, MEE, MVR, ATFD, and chemical treatment systems. We focus on stable operation, lower scaling risk, better recovery, controlled chemical consumption, and early identification of operational issues.
