Abstract
When broken down, the phosphorus component of most antiscalants can cause eutrophication in receiving surface water. Increased awareness of this environmental impact is prompting more stringent concentrate disposal restrictions for phosphorus and nitrogen. A possible solution to these problems is to develop stable and inherently biodegradable antiscalants without phosphorus groups. A team of researchers recently investigated the effects and possible side effects of a new environmentally friendly antiscalant for membrane installations.
