Abstract
A blend of micro-crystals of magnesium ammonium phosphate and other seed materials with magnesium hydroxide slurries reduces struvite scale in wastewater collection systems leading into waste-water treatment plants. These “seeds” act as attractants to phosphates and ammonia to allow the seeds to grow and remain dispersed throughout the waste water system. This greatly minimizes, or prevents struvite scale from building up in unwanted areas such as pipes, pumps, and valves that could potentially cause water flow blockage.
