Redesigning wastewater infrastructure to improve resource efficiency
Resource efficiency of wastewater management is a question of optimizing at the same time the management of resources in wastewater (e.g. water), the resources spent on treatment and transport (e.g. energy), the natural resources to protect (e.g. the receiving waters), and the anthropogenic resources (e.g. capital). For instance, wastewater can be treated to any given quality, but only at the ...

Grease trap treatment in a meat plant
Meat plants tend to be major producers of fats and grease and this present problems in the wastewater infrastructure as it is not soluble in water. This leads to build up in drains and grease traps and the traditional approach to disposal is to physically remove it and ship it off site for licensed disposal. A new approach is to use bioaugmentation to physically degrade the grease so that ...
