Shanghai BOQU Instrument delivers industrial metrology supported by robust production facilities, ISO-certified quality operations, and direct supply lines.
Macro Industrial Solutions: The Critical Role of Total Suspended Solids Process Control
In contemporary continuous-process engineering, the automated measurement and regulation of undissolved particulate mass—scientifically categorized as Total Suspended Solids (TSS)—stands as an uncompromising imperative for both regulatory compliance and plant operational thermodynamics. Unmonitored TSS fluctuations generate acute fouling phenomena across downstream reverse osmosis (RO) membrane arrays, precipitate severe scaling throughout multi-stage boiler feed loops, and destabilize microbial balances inside secondary clarification biological tanks.
Metrological Shift: From Gravimetric Laboratory Latency to In-Situ Photometric Feedback
Traditional gravimetric TSS assessment (Standard Methods 2540D) demands vacuum filtration, prolonged oven desiccation at 103–105°C, and precise analytical balances. While metrologically absolute, the associated 4- to 24-hour turnaround render standard lab protocols ineffective for closed-loop plant automation. BOQU Total Suspended Solids Controllers integrate state-of-the-art dual-beam infrared (860 nm) backscatter and 90°/135° nephelometric attenuation geometries, mathematically normalizing against particle chromacity and light source degradation to yield millisecond-grade responsive process metrics.
As an OEM/ODM manufacturing partner headquartered in Shanghai, BOQU Instrument resolves the historic vulnerability of optical sensors: biofouling and particulate encrustation. Our industrial TSS transmitters feature synchronized ultrasonic vibrating diaphragms, pneumatic pulse purge valves, or motorized silicone wiping mechanisms that guarantee clean optical windows without human intervention, maintaining analytical sensitivity across complex non-Newtonian media, high-salinity brines, and fluctuating pH environments.
ISO 7027 & USEPA 180.1 Compliance
Our instruments utilize monochromatic near-infrared light-emitting diodes (NIR LED 860 nm) complying fully with ISO 7027 standards to avoid sample color interference, alongside ratio-metric dual-beam detection circuits for USEPA industrial wastewater monitoring compliance.
Dynamic Particle Normalization
Integrated DSP (Digital Signal Processing) micro-controllers run proprietary multi-angle algorithms to dynamically separate true suspended solids mass from fluctuating particle shape distributions and micro-bubble entrainment common in high-rate aeration basins.
Decentralized Smart IoT Architecture
Native RS485 Modbus-RTU communications link directly to SCADA systems, industrial edge computers, and cloud monitoring gateways without external signal transmitters. Optional dual isolated 4-20mA channels drive PID chemical coagulation dosing pumps directly.

Integrated Instrumentation Architecture for Enterprise Clients
Field installations deployed across key processing sectors worldwide.
Industrial Wastewater Treatment
Discharge permits depend on consistent monitoring. Continuous online TSS and optical turbidity feedback allow operators to balance polymer dosing and manage sludge wasting before regulatory non-compliance occurs.
Steam & Water Analysis Systems (SWAS)
Trace particulates in boiler feedwater promote heat exchanger tube erosion and turbine deposits. BOQU supplies high-accuracy cation conductivity, sodium, and low-level turbidity monitoring panels for power utilities.
Biopharma & Fermentation Broth
Microbial cultures produce active molecules within specific environmental parameters. High-temperature pH and dissolved oxygen sensors withstand high sterilization steam pressures while tracking cell batch integrity.
Municipal Drinking Water Distribution
Protecting consumer health requires verified low suspended solids and consistent chlorine levels. Our multi-parameter panels feature continuous telemetry for pump stations and service reservoirs.
Intensive Recirculating Aquaculture Systems
Rapid biomass loading can deplete dissolved oxygen levels quickly. Industrial sensors linked directly to high-speed aeration blowers maintain critical water chemistry parameters around the clock.
Mining Separation & Tailings Thickening
Accurate suspended solids profiling governs flocculant dosing rates in raked thickeners, improving clarified water return recovery while lowering operational chemical expenditure.
Future Outlook: Edge-AI Metrology, Multi-Spectral Sensing & IIoT
The field of optical suspended solids determination is advancing from single-wavelength photometrics to intelligent multi-spectral processing. As biological treatment processes encounter tighter limits, traditional linear calibration models struggle with changing influent compositions. Shanghai BOQU Instrument is directing engineering investments into three primary technological domains:
Edge Machine Learning Transmitters
Next-generation TSS transmitters leverage on-device micro-inference architectures. By correlating scattered light patterns with contextual process data like pH and temperature, controllers compensate for fluctuating particle size distributions without manual site re-calibration.
Multi-Spectrum UV-Vis Absorption
Transitioning beyond single NIR wavelengths (860 nm) toward wide-band LED arrays from 254 nm to 910 nm. This configuration resolves suspended solids, turbidity, and chemical oxygen demand (COD) concurrently through a single, maintenance-free immersion probe.
Standardized IIoT Ecosystems
Full integration of modern communication protocols—including Modbus TCP, Ethernet/IP, Profinet, and secure MQTT telemetry. This lets system integrators link edge water analyzers directly into enterprise SCADA suites and hybrid cloud data lakes.
Engineering Questions: Suspended Solids & Analytical Control
Direct guidance from our metrology and factory engineering teams on specifying and operating online analyzers.
What is the fundamental difference between Turbidity and Total Suspended Solids (TSS)?
While often used interchangeably, Turbidity measures the optical transparency of water caused by light scattered by suspended particulates (expressed in NTU, FNU, or FTU according to ISO 7027). Total Suspended Solids (TSS) measures actual dry mass of undissolved matter per unit volume (expressed as mg/L or ppm). Turbidity optical readings can be correlated directly to TSS via multi-point calibration curves, provided that particle density, shape, and color profiles remain reasonably consistent.
Is BOQU an equipment broker or an authentic original equipment manufacturer (OEM)?
BOQU is a direct manufacturer founded in 2007 in Shanghai, China. Operating dual specialized facilities in Kangqiao and Lingang with over 4,632 m² of manufacturing space, we control the entire lifecycle internally: sensor glass blowing, photodiode alignment, CNC enclosure milling, circuit board assembly, temperature calibration baths, and final burn-in testing.
How do BOQU TSS sensors handle optical window fouling in activated sludge?
BOQU integrates two automated maintenance mechanisms: (1) An active silicone mechanical wiper blade driven by a high-torque DC motor designed for thick bioslurry, and (2) Integrated air-purge jets connecting directly to 0.2–0.4 MPa instrument air lines. These automated cleaning cycles run at user-defined intervals, minimizing routine service requirements at plant sites.
Can BOQU water instruments withstand steam sterilization cycles in biopharma processes?
Yes. BOQU maintains a specialized high-temperature water quality sensor laboratory. Products such as the pH5806 and DOG-208FA feature pressurized polymer reference gel structures and specialized glass matrices capable of withstanding in-situ SIP steam sterilization up to 130°C (0.4 MPa) without losing zero-point stability.
What hardware outputs and field protocols do your TSS controllers provide?
Standard instrument configurations provide dual isolated 4-20mA active outputs (assignable to TSS value and process temperature) alongside RS485 Modbus-RTU. Smart digital probe models output Modbus directly from the sensor head, connecting directly to PLCs or remote telemetry units (RTUs) without a separate transmitter.
What information is required to get a precise TSS controller quote for a custom project?
Please specify: (1) Anticipated TSS range (mg/L or g/L), (2) Water chemistry, pH range, and suspended media characteristics, (3) Process temperature and line pressure, (4) Mounting style (submersible basin pole, flow-cell, or pipeline weld flange), and (5) Power constraints (220VAC or 24VDC). Our engineering team can typically provide dimensional drawings and project configurations within 24 hours.
