INDUSTRIAL WATER TREATMENT SOLUTIONS
Field Service & Repairs
At Sepratech, we focus on one thing above all else: keeping your water treatment systems running reliably, efficiently, and safely so your operations don’t miss a beat. Since 1989, we’ve been supporting industrial and municipal facilities across North America with practical, field-tested service for clarifiers, filtration systems, ion exchange equipment, reverse osmosis units, and plant-wide controls.
We know that when your water systems go down, production is at risk, costs rise, and pressure mounts on your team. Our goal is to step in before that happens. By combining experienced field technicians, industry-leading technology, and a straightforward, problem-solving approach, we help you protect critical assets, extend equipment life, and get more value from every gallon you treat.
Lamella Clarifier Maintenance
Lamella inclined plate clarifiers play a crucial role in removing solids and conditioning water for downstream processes. Over time, plates foul, drives wear, and components fall out of alignment. Left unchecked, this leads to poor clarification, higher chemical use, and unplanned downtime.
Sepratech provides complete lamella clarifier maintenance, cleaning, and repair services for both our own units and existing equipment from other manufacturers. Our field service personnel are trained to work efficiently and safely in active industrial environments, with a clear focus on minimizing disruption to your production schedule.
We handle inspections, troubleshooting, targeted repairs, and full system refurbishments. Where needed, we supply and install replacement incline plates, drives, shafts, impellers, troughs, and other critical internals. Every service visit is tailored to your specific application so that we are not just fixing immediate issues but also looking for ways to improve throughput, reduce operating costs, and support your long-term process goals.
For facilities in power generation, petrochemical, refining, pulp and paper, and municipal water sectors, our clarifier services are often paired with system audits. These audits help identify bottlenecks, mechanical weaknesses, and opportunities for optimization, so your clarifier remains a reliable part of your treatment train rather than a recurring problem point.
MMF, MF, and UF Filtration System Maintenance
Filtration is often the workhorse of a water treatment system, protecting downstream equipment and ensuring consistent quality. Sepratech’s maintenance services for multi-media filtration (MMF), microfiltration (MF), and ultrafiltration (UF) systems are designed to keep these units operating at their intended capacity, with predictable performance and manageable operating costs.
Our multi-media filtration vessels are engineered for higher efficiency than conventional single-media filters, using carefully selected layers of sand, anthracite, and garnet to remove sediment down into the 10-micron range. In the field, that efficiency depends on proper media loading, flow distribution, and backwash performance. During maintenance, our team evaluates media condition, checks internals, verifies flow and pressure conditions, and addresses any issues affecting filtration quality or run times.
These systems are widely used as stand-alone filtration units, as pretreatment for reverse osmosis, deionized water, carbon, and cartridge or bag filters, and as post-treatment after clarification for pin floc removal. We support both smaller, single-unit installations and larger, multi-unit configurations serving municipal, institutional, and industrial applications.
Where needed, we can adapt your system for manual, semi-automatic, or fully automated operation. Our focus is always on practical operation: controls that your team can work with, and systems that integrate smoothly into your overall water treatment process without costly custom programming.
Softener and Ion Exchange System Maintenance
Hardness, scale, and dissolved solids can quietly erode the performance of boilers, membranes, and process equipment. Sepratech’s softener and ion exchange maintenance services help you keep these risks under control while extending the life of your assets.
We service and support anion, cation, and mixed-bed ion exchange systems used for softening, deionization, and post-RO polishing. Properly maintained softeners reduce hardness and scale formation, provide both short- and long-term cost savings, lower maintenance and chemical consumption, and improve the efficiency of downstream equipment. When these systems are neglected, you typically see higher energy use, more frequent cleanings, and shortened membrane and boiler life.
Our team works with you to ensure your ion exchange systems are matched to your actual water quality and production demands. That can include reviewing resin condition, regeneration performance, flow patterns, and control settings, as well as evaluating whether your current configuration is still the best fit for your process.
We support a wide range of industrial users and municipal plants, including power utilities, petrochemical facilities, refineries, pulp and paper mills, and drinking water and wastewater treatment facilities. In many cases, ion exchange systems are integrated alongside lamella clarifiers, mobile clarifiers, and RO systems. Because Sepratech works across all of these technologies, we can look at your treatment process as a whole rather than just one unit at a time.
Reverse Osmosis (RO) System Maintenance
Reverse osmosis is often the backbone of high-purity water production, but RO systems are sensitive to feedwater quality, scaling, fouling, and operating conditions. When performance starts to slip, it can quickly affect downstream processes and overall plant reliability.
Sepratech’s RO maintenance services focus on protecting membrane integrity, maintaining throughput and recovery, and keeping water quality within your required specifications. While every system is different, our work typically includes inspection of pre-treatment performance, evaluation of operating data, cleaning or replacement of RO membranes, and attention to pumps, internals, and controls.
We understand that RO performance is not just about the skids themselves but about the entire treatment train upstream and downstream. Because we also maintain clarifiers, filtration systems, and ion exchange units, we can pinpoint whether an RO issue is caused by membrane condition, pre-treatment gaps, or process changes elsewhere in the facility.
Our team aims to prevent unplanned outages by identifying early warning signs during routine service visits. Where appropriate, we discuss options to improve resilience and ease of operation, whether through better pre-treatment, adjusted setpoints, or control upgrades.
Programmable Logic Controller (PLC)
Modern water treatment systems depend on reliable control. Even the best-designed clarifier, filter, softener, or RO unit will underperform if the controls are poorly configured or outdated. Sepratech provides services for programmable logic controllers and associated control systems to help keep your operations stable, responsive, and easy for your team to manage.
With PLC services, we help ensure your equipment is starting, stopping, backwashing, regenerating, and alarming as intended. This can involve programming, troubleshooting, optimization of sequences, and integration of new equipment into existing control architectures. Our goal is to make your systems more intuitive for operators while improving reliability and reducing nuisance alarms or manual workarounds.
Because our controls work is rooted in real-world process understanding, we are not just writing code in isolation. We are looking at how each control decision affects water quality, equipment health, and production uptime. This holistic approach is especially valuable for sites that have grown or changed over time and now need their controls to catch up with reality.
