Featured Suspended Solids & Analytical Water Sensors
Engineered in our 4,632 m² Shanghai manufacturing base, each optical and electrochemical sensor undergoes 48-hour continuous signal stress testing and rigorous factory calibration.
Global Landscape: Why Inline Suspended Solids Sensing Governs Industrial Compliance
Total Suspended Solids (TSS) and Mixed Liquor Suspended Solids (MLSS) represent critical mass metrics across chemical manufacturing, industrial wastewater remediation, mining effluent, and biopharmaceutical purification.
Regulatory Fines & Discharge Enforcements
EPA Clean Water Act, EU Water Framework Directive (WFD 2000/60/EC), and China GB 8978-1996 mandate sub-second monitoring of total discharge solid loads. Gravimetric oven-drying methods introduce 4- to 24-hour analytical lag, preventing timely mitigation of clarifier overspills and sludge bulking.
Infrared 860nm Dual-Beam Technology
Modern suspended solids transmitters utilize near-infrared (NIR) backscattered and 90° nephelometric attenuation (ISO 7027 compliant). By operating beyond visible wavelengths (860 nm), optical interference caused by biological sample coloration, dissolved dyes, and ambient sunlight is completely suppressed.
Edge Digitization via RS485 Modbus
Legacy 4–20 mA current loops are exposed to galvanic grounding noise and line attenuation over long industrial runs. Our smart digital probes integrate high-speed DSP processing directly inside the 316L/Titanium probe body, feeding calibrated TSS, temperature, and diagnostics straight to SCADA via Modbus RTU.
| Evaluation Parameter | Optical NIR 90° Nephelometry | Multi-Beam NIR Backscatter | Gravimetric Lab Standard (EPA 160.2) |
|---|---|---|---|
| Typical Analytical Range | 0.01 to 4,000 NTU (0–2,000 mg/L) | 0.1 to 50,000 mg/L (Up to 100 g/L MLSS) | 0.1 mg/L to dynamic filter capacity |
| Primary Target Media | Drinking potable water, final treated effluent | Activated sludge, aeration tanks, paper pulp | Offline validation samples |
| Response Latency | < 2 seconds real-time continuous | < 1 second continuous loop tracking | 4 to 24 hours (Filtration, dry, weigh) |
| Fouling Mitigation | Automated silicone wiper or ultrasonic burst | Compressed air purge or dual-wavelength ratio | Manual human handling required |
| SCADA Integration | Direct RS485 Modbus RTU + 4-20mA loop | RS485 Modbus RTU / Industrial IoT Hub | Manual ERP / LIMS input entry |
Engineered in Shanghai: Unmatched Manufacturing Speed & Efficiency
Since 2007, Shanghai BOQU Instrument has replaced fragmented supply middlemen by uniting sensor fabrication, glassblowing, optical assembly, and PCB surface-mounting under one vertically integrated ecosystem.
China's Dedicated High-Temp Lab
BOQU operates China's specialized high-temperature water quality sensor calibration laboratory. Every suspended solids and pH/DO transducer is stress-tested against thermal shock, cyclic pressure, and volatile organics before packing.
Complete OEM/ODM White-Labeling
Whether you require custom immersion flanges, specialized titanium sensor housings for sea-water desalination, custom firmware registers, or branded silk-screened front bezels, our in-house engineering team provides turnarounds within 10 business days.
Traceable Batch Quality & Reliability
Compliant with ISO 9001 and ISO 14001, each sensor carries an etched serial matrix linked to its individual optical zero-point, calibration linearity curve, and pre-shipment aging data. Full material mill test certificates (MTR) are delivered on demand.
Mission-Critical Deployment Scenarios Across Global Geographies
Field-tested under extreme climatic, thermal, and biological fouling conditions, our suspended solids hardware is built for continuous resilience.
Wastewater & Sludge Control
Real-time MLSS feedback inside biological aeration basins optimizes Return Activated Sludge (RAS) pumping rates, preventing bio-mass starvation and reducing high compressor aeration energy waste by up to 22%.
Municipal Potable Water
High-sensitivity nephelometric TSS sensors detect early filter sand breakthrough and rapid changes in source raw water following seasonal storm surges, protecting downstream membrane filtration systems.
Chemical & Pigment Processing
Corrosion-resistant PVDF and sapphire optical windows endure harsh solvent mixtures, acidic precipitation, and highly abrasive inorganic slurry loops without optical window erosion or drift.
Industrial Aquaculture & RAS
Continuous tracking of uneaten feed pellets and organic bio-excretion loads in Recirculating Aquaculture Systems (RAS) prevents sudden gill asphyxiation and optimizes automated drum-filter backwash cycles.
Global Procurement Checklist & Next-Gen Sensor Trends
What multinational EPC contractors, water authorities, and systems integrators evaluate before placing multi-thousand unit wholesale orders.
Mechanical & Ingress Resilience
Ensure sensors provide IP68 submersible certification (at minimum 10m depth continuous submersion), hermetically sealed PUR/PTFE signal cabling, and anti-static poly-carbonate or 316L stainless steel wet-end metallurgy.
Predictive Self-Cleaning & Health AI
Next-generation TSS transmitters incorporate integrated photodiode degradation compensation and automatic optical cleanliness diagnostic alerts. Our auto-wiper assemblies reduce routine plant maintenance intervals from weekly to biannual.
Full Supply Chain Autonomy
Avoid vendor lock-in with closed proprietary transmitters. BOQU open-standard RS485 Modbus RTU enables engineers to plug sensors straight into Rockwell, Siemens, Schneider PLCs or custom cloud telemetry gateways without intermediary licensing.
