PROBEST: Empowering the Entire Sewage Treatment Process with Precision Monitoring to Safeguard Water Quality

Water is the source of life, and high-quality water is the cornerstone of ecological balance and social development. In the field of sewage treatment, from sewage collection to compliant discharge or reuse, accurate and real-time water quality monitoring is the core prerequisite for ensuring the stable operation of treatment processes and the safety of effluent water. As a professional manufacturer of water quality analysis and monitoring instruments, PROBEST deeply understands industry needs and provides full-process water quality monitoring solutions for Sewage Treatment Plants (STPs) worldwide with cutting-edge technology and reliable products, helping the sewage treatment industry achieve efficient, compliant, and sustainable development.

The process of a Sewage Treatment Plant (STP) involves several key stages, and each stage requires strict control of water quality parameters to achieve efficient removal of contaminants and proper management of sludge:

Preliminary Treatment: Raw sewage first flows into a Bar Screen Chamber to remove large floating debris such as rags and plastics. The wastewater then moves to an Equalization/Collection Tank, which helps regulate the flow and composition of the sewage. At this stage, monitoring of water quality parameters such as flow rate and turbidity is the first line of defense to avoid impact on subsequent processes.

Primary Treatment: In the Primary Settling Tank, the flow rate is reduced, allowing heavy organic solids (primary sludge) to settle to the bottom by gravity. Lighter materials such as oils and grease are skimmed off the top. Monitoring of parameters such as suspended solids and sludge concentration at this stage directly affects sedimentation efficiency and subsequent treatment load.

Secondary Treatment (Biological): The wastewater enters an Aeration Tank, where air is introduced to promote the growth of microorganisms that break down organic matter. This mixture then goes to a Secondary Settling Tank where the microbial mass (waste activated sludge) settles out. Some of this activated sludge is returned to the aeration tank to maintain the biological process, while the excess is sent for sludge treatment. Real-time monitoring of key parameters such as Dissolved Oxygen (DO), ORP, and Mixed Liquor Suspended Solids (MLSS) is crucial to ensuring the efficient progress of biochemical reactions.

Tertiary Treatment & Disinfection: The water then passes through a Dual Media Filter to remove finer suspended particles. A Chlorination Dosing System adds chlorine to the water in a Chlorine Contact Tank to kill any remaining pathogens and disinfect the water before it is designated as treated water for reuse. Monitoring of parameters such as turbidity, residual chlorine, total phosphorus, and total nitrogen at this stage is the key guarantee for ensuring the safety and compliance of the effluent water.

Sludge Management: The sludge collected from the settling tanks is transferred to Sludge Drying Beds, where water is removed to produce dewatered solids for final disposal. Monitoring of parameters such as sludge moisture content and heavy metal content is an important basis for ensuring the compliance of sludge disposal.

To meet the monitoring needs of the entire sewage treatment process, PROBEST has customized high-precision water quality analysis and monitoring instruments covering all stages. Whether it is flow and turbidity monitors for the preliminary treatment stage, dissolved oxygen and sludge concentration analyzers for the biological treatment stage, or residual chlorine, total phosphorus, and total nitrogen detectors for the advanced treatment stage, all products feature high measurement accuracy, strong stability, and excellent anti-interference capabilities, which can adapt to the complex and harsh operating environment of sewage treatment plants. Our instruments not only support real-time data collection but also can be connected to PLC systems through intelligent modules RS485 to realize remote data transmission, trend analysis, and abnormal early warning. This helps sewage treatment plants achieve refined operation and intelligent management, effectively reduce energy consumption and chemical dosage, and improve operational efficiency.

With years of experience in the industry, PROBEST has always adhered to the concept of "Precise Monitoring, Guarding Water Quality". Relying on a strict quality control system, continuous technological innovation capabilities, and comprehensive after-sales service, we have won the trust of customers around the world.
