ZWIN-WQMS06 Water Quality Multi-Parameter Smart Online mini Station

ZWIN-WQMS06 water quality multi-parameter intelligent online mini station is an online water quality monitoring system that integrates water sampling unit, pretreatment and water distribution unit, detection and analysis unit, automatic control unit, data acquisition and transmission control unit, remote monitoring unit and auxiliary unit.

Product Composition

1. Water sampling unit

The main function of the water sampling unit is to ensure that the water samples at the water sampling point are led to the monitoring system instrument room under any circumstances and meet the needs of the drainage unit and analytical instruments. The water sampling unit generally includes water sampling structures, water sampling pumps, water sampling pipelines, cleaning equipment and insulation equipment. The water sampling system adopts dual-circuit water sampling, and the running status of the water pump can be controlled by the program. It can also protect itself in the event of a power outage and automatically recover when the power is on again.

2. Pretreatment and water distribution unit

The system settles the raw water according to the suspended matter situation of the on-site water sample, and then passes the still water sample through a high-precision filter element for precise filtration. The filtered water sample is then provided to the instrument for analysis and testing.

3. Detection and analysis unit

The automatic water quality analysis unit is the core part of the fixed water quality monitoring system, which is composed of automatic detection instruments that meet the requirements of various detection items. The selection principle of the instrument type is that the instrument measurement range meets the water quality analysis requirements, and the measurement results are consistent with the standard method; the instrument structure is reasonable and the performance is stable; the operating cost is reasonable, the maintenance is small, and the maintenance cost is low; and there is less secondary pollution.

4. Automatic control unit

The system control unit is composed of base station control software and industrial control computer hardware. It is used to sense changes in signals from online detection instruments and equipment, and send relevant control commands, including: water intake unit control, instrument operation control, instrument data acquisition and storage, video acquisition and transmission, real-time water quality analysis statistics and upload, remote communication, process scheduling, etc., to ensure continuous, reliable and safe operation of the system.

5.Data collection and transmission unit

The data acquisition and transmission unit mainly realizes the functions of monitoring the on-site operation status, setting the on-site operation parameters, storing the historical data and system operation log, communicating with the host computer, etc. It also has the data storage capability.

ZWIN-TP1006 Total Phosphorus Water Quality Online Automatic Monitoring

The main purpose of the automatic total phosphorus monitoring is to monitor phosphorus-containing compounds in the form of various phosphates in water. They are divided into orthophosphates, condensed phosphates (pyrophosphates, metaphosphates and polyphosphates) and organically bound phosphorus (such as phospholipids, etc.). They are widely used in sewage monitoring points, surface water monitoring stations, river sections and drinking water source monitoring stations.

ZWIN-TN1006 Total Nitrogen Water Quality Online Automatic Monitoring

The main purpose of the total nitrogen automatic monitoring is to monitor nitrogen compounds in various forms in water. In natural water and wastewater, nitrogen almost always exists in the form of various nitrates, which are divided into nitrate nitrogen, nitrite nitrogen, ammonia nitrogen and organic nitrogen (protein, amino acid, etc.). They exist in the water environment and are the main indicators of eutrophication of water bodies. The total nitrogen automatic monitor is widely used in sewage monitoring points, surface water monitoring stations, river sections and drinking water source monitoring stations.
