Mechanical Plants

Mechanical wastewater plants utilize a variety of treatment technologies and related systems.

In attached-growth systems, biomass attaches to a medium to retain and grow microorganisms. Common types include moving bed biofilm reactors (MBBRs), rotating biological contactors (RBCs), trickling filters, and biotowers.

In suspended-growth systems, microorganisms and bacteria are suspended in wastewater as waste flows around them. Common types include oxidation ditches, extended aeration, sequencing batch reactors (SBRs), membrane bioreactors (MBRs), and a variety of other activated sludge plants ranging from pre-packaged to custom designed.

These systems are typically combined with upfront headworks/screening systems, which remove solids and debris, as well as post-treatment disinfection systems, which improve water quality.

With several different treatment techniques available, Shive-Hattery takes the unique needs of each client into consideration, including initial equipment costs, system reliability, operations and maintenance features and costs, and certification levels of existing operators.

The end result is a customized, cost-effective wastewater solution specifically targeted to meet your goals, such as energy efficiency, increased capacity, reliability/operability/maintainability, and expanded plant lifecycle.
