A common practice in the waste water treatment within the steel plant is to combine waste waters from several different types of operations for treatment in a so-called terminal treatment plant. This practice has been particularly successful in the handling of waste waters from the various finishing operations.
Waste management is one of the most important and serious issues facing many developing countries. The main purpose of this research involves reusing wastewater generated by the paint industry in the manufacture of cement bricks and tiles, in addition to improving some mechanical properties of the cement bricks and tiles. Since large …
A cement plant wastewater treatment system has to remove minute particulate that remains after production. This task is more important when a closed system - the industry standard - is in place and waste water is reused over and over. Here we discuss why and how important is water treatment for cement plant.
This article provides a detailed analysis of strategies for treating steel industry waste in wastewater treatment. Recent advancements in membrane …
After treating the steel in a pickling bath, the steel is rinsed with water. After rinsing, the wastewater contains high amounts of acids, and thereby has a low pH value. Before disposing or reusing of the wastewater, it has to be neutralized by addition of base reagents to avoid harming the recipient.

With the improvement of wastewater recycling requirements of iron and steel industries, the advanced wastewater treatment technology represented by the ultrafiltration and the reverse osmosis double membrane( UF / RO) is gradually developing. The UF / RO was used to desalt the integrated wastewater from a steel mill after physicochemical / …
However, there is a huge capacity gap between the steel industry and the cement industry, and hence, the supply of GBFS can hardly meet the demand. At present, few studies have focused on the preparation of cementitious materials with GBFS-like properties, and a detailed summary of the mechanisms is lacking. ... 2018), wastewater …
Spent refractory brick (SRB) generated from the steel industry has a high magnesium content. In this study, a procedure was developed to utilize SRB gravels for efficient recovery of phosphate and ammonia from high strength wastewater via struvite (MgNH 4 PO 4 ∙6H 2 O(s)) precipitation. Mg 2+ and Ca 2+ were first leached from SRB …
