Global water shortages due to droughts, population growth and stringent enviromental discharge regulations have created increasing interest in water reuse and recycling. Pressured membrane processes, in particular, reverse osmosis (RO), are well-established technologies in water treatment. However, the drawbacks of RO membrane filtration include high energy consumption and operational costs. In addition, the volume of RO concentrate (reject) produced by RO systems is significant and, in most cases, contain high ...

Contaminated mine water is generated when rock containing sulphidic minerals is exposed to water and oxygen, resulting in the production of acidity and high concentrations of metals and sulphate in the water. Mine drainage, process water and storm water associated with industrial activities are the main types of water produced in mining operation. The two primary aims of the treatment of contaminated mine water are to neutralize acidity and removal metals. Lenntech provides sustainable complete water treatment ...

Evaporation is a proven and effective way of reducing the volume of many waste streams. HRS Heat Exchangers offer solutions for the evaporation and concentration of waste streams from a wide variety of industries, such as water treatment, bioenergy and food production. A common issue when treating certain waste streams with standard evaporation technologies (such as falling film) is that when heated, they can foul equipment. As the concentration of solids increases during the evaporation process, so does the risk ...
