LONGF-W Suspended Solids & Sludge Concentration Meter
High-Precision Online Suspended Solids and Sludge Monitoring for Wastewater Treatment
Product Overview
The LONGF-W Suspended Solids & Sludge Concentration Meter is an advanced online analytical instrument designed for continuous monitoring of suspended solids (SS), sludge concentration, and wastewater quality in municipal and industrial treatment processes.
Using dual-beam infrared light scattering technology, the system delivers reliable and accurate measurements of activated sludge, return sludge, mixed liquor suspended solids (MLSS), and treated effluent. The sensor automatically compensates for contamination-related interference, ensuring stable performance even in demanding environments.
The instrument consists of a high-performance transmitter and a submersible sensor that can be easily installed in tanks, pipelines, drainage channels, pressurized pipes, and natural water bodies.
Typical Applications
Municipal wastewater treatment plants
Industrial wastewater treatment systems
Activated sludge process monitoring
Biological treatment process control
Environmental monitoring stations
Pharmaceutical and biotechnology industries
Petrochemical and energy industries
Water discharge compliance monitoring

Frequently Asked Questions (FAQ)
What is a suspended solids concentration meter?
A suspended solids concentration meter is an online instrument used to continuously measure the concentration of solid particles suspended in water or wastewater. It is commonly used in wastewater treatment plants to monitor sludge and process efficiency.
What industries use suspended solids analyzers?
Suspended solids analyzers are widely used in municipal wastewater treatment, industrial effluent treatment, environmental monitoring, pharmaceutical manufacturing, chemical processing, and energy industries.
Can LONGF-W measure activated sludge concentration?
Yes. The LONGF-W is ideal for monitoring activated sludge, return activated sludge (RAS), mixed liquor suspended solids (MLSS), and other biological treatment processes.
Does water color affect measurement accuracy?
No. The instrument uses infrared light scattering technology, which significantly reduces the impact of water color and improves measurement reliability.
How often does the sensor require maintenance?
Maintenance requirements are minimal. Users can further reduce maintenance frequency by selecting the optional automatic cleaning brush or pneumatic cleaning system.
Is the sensor suitable for outdoor installations?
Yes. The transmitter is rated IP65 and the submersible sensor is rated IP68, making the system suitable for both indoor and outdoor wastewater monitoring applications.

Introduction:
The suspended solids sludge concentration meter is an online analytical instrument designed to measure the concentration of suspended solids in the treatment of municipal sewage or industrial wastewater. Whether it is evaluating activated sludge and the entire biological treatment process, analyzing the wastewater discharged after purification treatment, or detecting the concentration of sludge at different stages, the suspended solids sludge concentration meter can give continuous and accurate measurement results. The suspended solids sludge concentration meter consists of a transmitter and a sensor. The sensor can be easily installed in the pool, drain pipe, pressure pipe or natural water body. The photoelectric sludge concentration meter can automatically compensate for the interference caused by pollution. Application: water quality monitoring; water treatment discharge; environmentally friendly biopharmaceuticals; petrochemical energy.
