Case Study: Industrial Facility – Nederland, Texas
Emergency Clarification & Dewatering to Maintain Plant Operations During Critical Maintenance
A major industrial facility in Nederland, Texas, relied on a single 3,800 gpm clarification unit for its entire water treatment process. When the clarifier began experiencing operational failures outside the plant’s normal shutdown window, the situation quickly escalated into a production-critical emergency. Sludge handling issues, solids breakthrough, and overloaded downstream filtration left the plant with no margin for error. Immediate action was required to maintain operations and prevent production disruption.
The Challenge
The plant faced multiple compounding problems:
The primary clarifier’s sludge waste system failed, creating a non-fluidized sludge bed that could no longer settle solids effectively.
The clarifier lost its ability to reduce inlet solids, sending a heavy particulate load downstream.
Filtration equipment was overwhelmed, forcing constant backwashing and interrupting normal operations.
The facility needed to perform essential maintenance on the clarifier, but no shutdown window was available.
The plant needed reliable temporary clarification and sludge dewatering—fast.
Without immediate intervention, the plant risked process downtime, environmental issues, and a cascading failure of the entire treatment system.
Sepratech’s Approach
With decades of experience supporting industrial clients during emergencies, Sepratech understood the urgency. The priority was clear: restore clarification capacity quickly while enabling the facility to perform required maintenance on its primary equipment.
Sepratech mobilized a rapid-response engineering and field operations team, coordinating logistics, delivery, installation, and startup in record time.
Key Takeaways
Four lamella clarifiers and a belt press were mobilized and producing clarified water in under one week.
Sepratech provided a full temporary treatment train while the primary clarifier underwent maintenance.
A dedicated Sepratech operator maintained performance and responded immediately to process changes.
The belt press prevented sludge accumulation, protecting downstream equipment and maintaining solids control.
The Solution: Four Lamella Clarifiers + Belt Press + 24/7 On-Site Operations
To replace the capacity of the failing 3,800 gpm clarifier, Sepratech deployed:
-
Four lamella clarifier units
-
A complete belt press system for sludge dewatering
-
All associated pumps, tanks, piping, and ancillary equipment
-
A dedicated on-site operator available around the clock
The lamella clarifiers provided the high-rate settling the facility needed to manage solids loading, while the belt press handled sludge removal efficiently—preventing the very sludge bed failure that caused the initial problem.
Sepratech’s 24/7 operator support ensured stable operation, immediate troubleshooting, and seamless coordination with their’ internal team. This constant presence was essential to keeping the temporary system running at peak performance.
Results
Sepratech achieved what the facility urgently needed:
Fully functional temporary clarification within one week of receiving the purchase order
Continuous supply of clarified water, allowing it to complete the cleaning and maintenance of their main clarifier
Stabilized downstream filtration, eliminating the overload and backwashing cycle
Zero disruption to plant operations, despite the failure of the site’s only clarifier
A reliable bypass system that kept the facility compliant and productive
With Sepratech’s temporary system handling the plant’s clarification demands, the plant was able to complete critical maintenance work safely and efficiently—without shutting down production.
