Wastewater Monitoring System at Long Son Petrochemical Complex

According to the Decree 40 of the Government, factories and businesses which are likely to cause environmental pollution and have a discharge scale of 500m³/day (24h) or more must install automatic and continuous wastewater quality monitoring system.

Recently, NK Engineering has supplied and installed a continuous and automatic wastewater monitoring system as a turnkey for Long Son petrochemical complex, which fully meets the regulations of the Government and the Ministry of Natural Resources and Environment.

Based on Endress+Hauser instruments portfolio, NK Engineering has built a wastewater monitoring system that includes:

• Sensors measure the basic parameters required by Decree 40: Flow (inlet & outlet), pH, temperature, COD, TSS, Ammonia
• The transmitter CM448 connects to sensors via the Memosens technology of Endress+Hauser
• Datalogger – The communication instrument can dislay and extract data directly, not through intermediaries
• The Autosampler, which directly connects to Datalogger, will take samples and store samples at 4°C
• Other devices such as: Camera, fire alarm, pump, UPS, …

Monitoring parameters are transmitted to the MONRE, while the customer will monitor online 24/7 on the webserver system built by NK Engineering.
