Wastewater from steel plants contains a large amount of suspended solids and refractory organic matter，a large amount of secondary pollutants will also be produced during the wastewater treatment process. These pollutants will not only lead to eutrophication of water bodies, but also cause serious harm to human health.

A large amount of wastewater is produced in the production process of steel mills, and a large amount of sludge is generated in the process of sewage treatment, which is prone to leakage during transportation and storage, causing secondary pollution. In addition, as the amount of wastewater discharge increases, the cost of wastewater treatment will also increase.

The sand pump machine from OCEAN Pump can extract iron and steel scrap at high concentrations and resist the increased wear and tear produced by these particles.

The sewage treatment plant is a production enterprise that receives and treats urban sewage. Various impurities in urban sewage will be collected through the pipe network and finally enter the sewage plant, especially the sediment contained in the sewage. These sediment particles come from the sediment carried in the daily sewage, the sediment washed into the pipeline system by the surface runoff brought by the combined rain and sewage system, and the sneak discharge of some special enterprises, even includes the sediment cycle formed by some process operations in the plant, etc. Therefore, regular dredging is an important operation in some regional sewage plants that are greatly affected by inorganic particles such as sediment.

OCEAN Pump brand agitated submersible slurry pump is specially designed for this kind of working condition, which can not only efficiently extract the sand in the sewage tank, but also take into account strong wear resistance.

Road construction, real estate, transportation and some infrastructure projects all need to rely on sufficient and high-quality sand and gravel aggregates for support. The reduction and prohibition of natural river sand mining in some countries have increased the production demand of artificial machine-made sand several times. Because of its advantages such as large raw material reserves, high sand output, and good quality of finished products, it has been widely used in various construction projects.

OCEAN Pump has special pump matching solutions for machine-made sand factories and sand washing plants, including sand suction pumps, clean water pumps, fine sand recovery pumps, special pumps for filter presses, etc. We have strong cooperation with major machine-made sand factories and supporting manufacturers.
