Concrete Wash Water Disposal Agg-Net

2021-6-13 · Water contacting freshly exposed or poured concrete takes on an alkaline pH value (c.13) due to chemical reactions between the water and free lime particles within the cement. At a typical concrete plant, up to 12,000m3 of water is consumed every year, which means that the washing down of machinery, equipment and transportation vehicles becomes problematic.

Influence of concrete mixer washing waste water on

The world's population will be facing water shortage problems by 2050. Recycling and treatment of residual water and reusing it in real life applications may help to solve this problem. However, the total cost of the treatment processes is estimated to be very high. The reuse of concrete mixer washing waste water without previous treatment may contribute to a significant reduction in the cost

» Water Recycling Concrete Washout Area Best

2019-6-24 · Water Recycling Concrete Washout Area. On London Dock, we were looking for a solution to concrete washout on site. We did not think that using lined skips or deep drip trays was effective as quite often it would rain heavily and fill the skips/trays up quickly. If the tray overloaded, the water would land on the ground or on a membrane we had
