Manufacturing of items we use in our daily lives create by-products. These by-products will vary with the type of industry and could include metals from electroplating. By-products influence total dissolved solids (TDS) levels in wastewater that are eventually received at a Water Reclamation Facility (also known as wastewater treatment facility).
Pretreatment programs help regulate industrial users by monitoring what additions are being made to water related processes at each facility. Industrial processes include adding acids, bases oxidizers, reducers, coagulants and final neutralization chemicals. The pretreatment department of the District is working with those industries to reduce each of these additives to the least amount possible and still achieve the desired outcome for the specific process.
Best Management Practices
The pretreatment division of Cherokee and the industrial users work together to establish best management practices (BMPs). BMPs are a specific set of procedures that a business will use to fine-tune each industrial process. These practices help regulate the amount of each material additive needed in a process, minimizing the final discharge to achieve lower TDS. As an added benefit to the use of BMPs, industrial chemical costs can be reduced as well. Industries in the Cherokee Metropolitan District contribute 1.6% of the overall TDS concentration received at the wastewater treatment facility.
