Keeping equipment in good running order can often take more time than you have to spare. Recently a well-run municipality was faced with a chemical mixer that had accumulated rigid nearly impossible to remove deposits over the course of 20 years of use. The mixer was used to blend polymer with other coagulants such as Alum and ACH (Aluminum Chlorohydrate) before sending the solution to be used in the drinking water plant. The deposits were resistant to power washing and chemical attack (citric acid). However, Blue Earth Products’ Floran product line is specifically formulated to handle this kind of tough job. Using Floran CSR Plus with Catalyst, the deposit was easily removed with just a few low pressure surface spray applications and a garden hose spray to rinse.
