LotusWorks is seeking an experienced Wastewater Nightshift O&M Technician to support the safe, reliable, and continuous operation of a Water Reclaim Plant (WRP) within a mission-critical semiconductor manufacturing environment. This role is responsible for operating, monitoring, troubleshooting, and maintaining wastewater treatment and water-reclamation systems to ensure regulatory compliance, water-quality requirements, plant reliability, and maximum water recovery.

The ideal candidate will have strong hands-on experience operating and maintaining industrial wastewater treatment systems and be comfortable working independently during nightshift operations. This position requires strong troubleshooting skills, attention to detail, and the ability to respond effectively to alarms, equipment failures, process upsets, and water-quality excursions.

Responsibilities:

• Operate and maintain the Water Reclaim Plant to ensure continuous, safe, and reliable treatment and recovery of facility wastewater streams.
• Monitor plant performance through SCADA/HMI systems, field inspections, operator rounds, alarms, trends, and analytical results.
• Operate treatment processes including equalization, pH adjustment, clarification, filtration, membrane treatment, biological treatment, and polishing systems, as applicable.
• Operate and monitor advanced treatment systems such as UF, RO, NF, MBR, media filtration, activated carbon, ion exchange, and other treatment technologies where installed.
• Monitor and optimize water recovery rates, reject rates, membrane performance, and overall plant treatment efficiency.
• Monitor critical process parameters including flow, pressure, differential pressure, pH, conductivity, ORP, turbidity, TOC, TSS, temperature, and chemical concentration.
• Perform routine sampling and field analytical testing to verify treatment performance and reclaimed-water quality.
• Collect process and compliance samples for laboratory analysis in accordance with established sampling plans and procedures.
• Monitor incoming wastewater characteristics and identify changes that could impact biological, membrane, chemical, or downstream treatment processes.
• Adjust chemical dosing based on process conditions, analytical results, flow rates, and treatment requirements.
• Operate and maintain chemical systems including acid, caustic, coagulant, flocculant, antiscalant, biocide, sodium hypochlorite, bisulfite, and other treatment chemicals, as applicable.
• Monitor chemical inventories and coordinate replenishment to prevent interruptions to plant operations.
• Operate equalization tanks, transfer pumps, lift stations, feed pumps, recirculation pumps, chemical pumps, mixers, blowers, and associated equipment.
• Monitor tank levels and manage plant flows to prevent overflow, low-level conditions, hydraulic overload, or loss of treatment capacity.
• Perform startup, shutdown, isolation, and return-to-service activities for treatment systems and equipment.
• Perform routine backwash, flushing, clean-in-place (CIP), regeneration, and membrane cleaning activities.
• Monitor membrane differential pressure, normalized permeate flow, rejection performance, fouling indicators, and cleaning requirements.
• Identify deteriorating membrane performance and escalate conditions requiring cleaning, replacement, or engineering review.
• Operate and monitor sludge handling, solids separation, dewatering, filter press, centrifuge, or waste-solids systems, where applicable.
• Monitor biological treatment health where applicable, including DO, ORP, MLSS, sludge condition, nutrient balance, and process stability.
• Respond to plant alarms, equipment trips, high/low tank conditions, poor water quality, chemical-system failures, and abnormal process conditions.

Skills Required:

• Minimum 5 years of experience operating and maintaining industrial wastewater treatment systems.
• Hands-on experience with wastewater treatment, water reclamation, or related industrial water systems.
• Strong understanding of wastewater treatment processes, equipment, instrumentation, and chemical treatment.
• Experience monitoring and troubleshooting treatment systems and responding to process abnormalities.
• Ability to read and interpret P&IDs, equipment documentation, operating procedures, and system diagrams.
• Ability to work independently during nightshift and make sound operational decisions in a mission-critical environment.
• Strong troubleshooting, communication, documentation, and problem-solving skills.
• Ability to work safely around industrial equipment, chemicals, confined spaces, and process systems.
• Ability and willingness to support a 24/7 operation, including rotating shifts, overtime, callouts, and emergency response as required.
