Application Article of ACITEK ACATS430 Turbidity & TSS Sensor

1. Product Overview

ACITEK ACATS430 is a robust integrated optical sensor designed for simultaneous online monitoring of turbidity (0–4000 NTU) and total suspended solids (TSS, 0–20,000 mg/L). It complies with international standard DIN/EN 27027 / ISO 7027 via the 90° scattered light measurement principle, delivering high-precision and repeatable readings with detection limit as low as 0.006 NTUacitekinst....

The probe offers two housing options: hermetically sealed stainless steel for general water treatment, and titanium for corrosive high-salinity media. Scratch-resistant sapphire optical windows eliminate abrasion damage from sediment and sludge particles. Pre-calibrated at factory, it can be deployed directly without complex on-site calibration. Core highlights include lifetime service-free design, in-situ cleaning compatibility, predictive maintenance diagnostics, adaptive TSS calibration, flexible installation threads and customized cable length, which greatly cut long-term operation and maintenance costs for end usersacitekinst....

Operating parameters: 0–60°C working temperature, maximum 10 bar pressure resistance, T90 response time less than 30 seconds, supporting long-term continuous immersion monitoring in diverse water environments.

2. Core Application Scenarios & Matching Advantages

2.1 Municipal Drinking Water Treatment Plants

Application Points

Install ACATS430 at raw water intake, sedimentation tank outlet, filter tank and finished water pipeline for full-process clarity monitoring:

1. Real-time raw water turbidity early warning against mud runoff and source water pollution after rainfall;
2. Judge filtration efficiency of quartz sand and activated carbon filters to adjust backwashing frequency automatically;
3. Monitor finished water turbidity to ensure effluent meets national drinking water clarity standards.

Matching Product Strengths

• Ultra-low detection limit (0.006 NTU) meets strict low-turbidity monitoring requirements for clean water;
• Sapphire optical window resists abrasion from fine sand particles in raw water;
• Predictive maintenance function reminds operators of window fouling in advance, reducing manual sampling frequency.

2.2 Municipal Wastewater & Sewage Treatment Works

2. Secondary sedimentation tank sludge blanket detection: Prevent sludge loss caused by excessive outflow;
3. Final effluent discharge monitoring: Continuously record TSS and turbidity to satisfy environmental supervision discharge standards, avoid penalty for exceeding emission limits.

Matching Product Strengths

• Wide TSS measuring range up to 20,000 mg/L adapts to high-concentration sludge environment;
• Adaptive TSS calibration automatically optimizes conversion coefficient between turbidity and suspended solids, ensuring consistent data accuracy under variable sludge composition;
• Service-free design avoids frequent disassembly cleaning amid sticky activated sludge, cutting labor maintenance by over 70%.

2.3 Industrial Wastewater Treatment

Covers chemical, food & beverage, pulp & paper, mining and electroplating industries:

1. Chemical plant: Monitor precipitation tank effluent to control flocculant dosage and reduce chemical consumption;
2. Food & papermaking: Track fiber and organic suspended matter to optimize solid-liquid separation;
3. Mining & metallurgy: Titanium housing version resists acidic/alkaline corrosive wastewater and mine high-sediment water;
4. Recirculating cooling water: Monitor suspended particles to judge pipeline scaling risk and arrange blowdown cycles.

Matching Product Strengths

• Optional titanium body withstands corrosive, high-salinity industrial wastewater;
• 10 bar pressure tolerance fits pipeline inline installation of industrial process water;
• Customizable cable length supports long-distance underground tank layout.

2.4 Coastal Aquaculture & Seawater Monitoring

Application Points

1. Marine fish/shrimp breeding ponds: Monitor water turbidity to adjust water exchange frequency, prevent algae overgrowth and hypoxia caused by excessive suspended sediment;
2. Coastal estuary & offshore environmental monitoring stations: Track sediment transport, early warn red tide and eutrophication by TSS data;
3. Seawater desalination pretreatment: Monitor raw seawater suspended solids to protect RO membrane from particle abrasion.

Matching Product Strengths

Titanium probe body effectively resists seawater chloride corrosion; stable measurement under brackish water with complex sediment composition, compatible with ACITEK LDO dissolved oxygen sensor for multi-parameter integrated water quality monitoring of mariculture.

2.5 Surface Water & Ecological Environmental Monitoring

Deployed in rivers, lakes, reservoirs and landscape water:

• Continuously track turbidity and TSS fluctuation to trace external pollution sources;
• Provide long-term data support for water eutrophication, sediment deposition and ecological restoration assessment;
• Unattended submerged monitoring for remote environmental monitoring stations.

3. Universal Product Advantages for All Application Fields
