Market background

    The improvement of water environment quality is still a long-term process, and the discharge of industrial, agricultural and domestic pollutants poses a major threat to human health. It is expected that in the future, total water consumption will be at a high level, wastewater discharge will continue to rise, agricultural source pollutants and unconventional water pollutants will increase rapidly, and the transformation of water pollution from single pollution to compound pollution will further intensify, and the pollution situation will become more complicated and prevention and control The difficulty increases. If no major measures are taken, water pollution will cause heavy economic and health losses.

Solution

Water quality monitoring can measure pH, conductivity, dissolved oxygen, salinity, dissolved matter (TDS), temperature, turbidity, depth, oxidation-reduction potential (ORP). It can meet the measurement needs of various surface water, groundwater, industrial and domestic sewage, aquaculture and reclaimed water. It can be widely used in environmental protection, scientific research monitoring, production control and other fields. It is an ideal solution for environmental monitoring and management in the age of industrial automation.

1. Desalted water treatment

The desalinated water treatment process is generally a water treatment process that removes or reduces the strong electrolyte in the water to a certain extent, also known as the pure water treatment process. The more common desalinated water treatment processes include electrodialysis, ion exchange, reverse osmosis, EDI and so on.

2. Cooling circulating water system

The circulating cooling water system refers to a water supply system that exchanges heat through a heat exchanger and is cooled by a cooling tower before recycling. There are two types of open type and closed type. Generally composed of cooling equipment, water pumps and pipelines.

3. Boiler water treatment system

A boiler is a device that uses the heat or other energy released from the combustion of fuel to heat the intermediate heating medium to certain parameters. There are steam boilers and hot water boilers.

The purpose of boiler water treatment is to ensure the water quality of various steam and water in the boiler, to prevent the structure and corrosion of the boiler thermal equipment, and to ensure the safe, economic, energy-saving and environmentally friendly operation of the boiler.

4. Sewage treatment system

The sewage treatment system is a treatment system that removes or converts the main pollutants in urban sewage and industrial sewage into harmless substances through physical, chemical or biological treatment methods, so as to meet the relevant sewage discharge standards. The sewage treatment system is mainly composed of filtration, primary sedimentation, aeration tank, secondary sedimentation, disinfection and other processes.
