Sludge Thickening & Dewatering

Reducing Sludge Volumes and Disposal Costs

Over 500 projects complete

Introduction

Sludge thickening concentrates solids from primary and biological treatment processes, reducing disposal volumes and improving the efficiency of downstream handling. Effective sludge management is essential for minimising operating costs and ensuring compliant plant operation.

Robust Thickening Solutions

FLI CAP Technology supplies sludge thickening systems tailored to the needs of industrial sites, including DAF sludge storage, mixed-liquor thickening and transfer pumping. Our solutions help reduce water content and stabilise sludge for easier transport and disposal.

Integrated Storage & Pumping

We design complete sludge-handling arrangements featuring dedicated storage vessels, duty/standby pumps, automated valves and instrumentation. These systems integrate seamlessly with DAF units, clarifiers and biological processes.

Safe & Compliant Operation

All sludge tanks and pipework are designed to meet chemical and environmental containment standards. Bunded vessels, level monitoring and access provisions ensure safe operation and simple maintenance.

Process Technologies

Pumping Stations

FLI CAP Technology’s effluent pumping systems are engineered to transfer industrial wastewater reliably between treatment stages, maintaining stable flows and protecting downstream processes.

Screening & Filtration

FLI CAP Technology’s screening and filtration systems are engineered to protect downstream treatment processes by efficiently removing solids, fibres and debris from industrial effluent.

Balancing & Effluent Storage

FLI CAP Technology designs and delivers balancing and effluent storage systems that equalise flows and loads, stabilise treatment performance and protect downstream processes across industrial effluent treatment plants.

pH Correction & Chemical Dosing

FLI CAP Technology’s pH correction and chemical dosing systems are engineered to deliver accurate, automated control that protects downstream treatment processes and ensures consistent discharge compliance.

Dissolved Air Flotation (DAF) Clarification

FLI CAP Technology’s Dissolved Air Flotation (DAF) systems are engineered to deliver reliable primary clarification, removing suspended solids, fats, oils and grease from high-strength industrial effluent.

Membrane Bio Reactor (MBR)

FLI CAP Technology’s Membrane Bioreactor (MBR) systems combine advanced biological treatment with membrane filtration to deliver high-quality effluent for sites with stringent discharge or reuse requirements.

Activated Sludge

FLI CAP Technology’s activated sludge systems provide proven, robust biological treatment for high-strength industrial effluent, delivering reliable removal of BOD, ammonia and nutrients across demanding manufacturing environments.

Moving bed Bioreactor (MBBR)

FLI CAP Technology’s Moving Bed Bioreactor (MBBR) systems provide robust, high-rate biological treatment for industrial effluent, delivering stable COD and ammonia removal under variable loading conditions.

Tertiary Treatment

FLI CAP Technology delivers advanced tertiary treatment solutions to polish industrial effluent, achieve strict discharge consents and enable safe water reuse.

Water Reuse & Reverse Osmosis (RO)

FLI CAP Technology designs and delivers water reuse and reverse osmosis (RO) systems that recover high-quality water from treated effluent, helping industrial sites reduce freshwater demand, lower discharge volumes and improve sustainability performance.
