The present invention relates generally to a system and method for treating wastewater in a filter media apparatus having a draft tube system. The filter media may be walnut shell media.

Water treatment apparatus incorporating walnut shell filter media and a draft tube system

Water filter apparatus incorporating walnut shell filter media and a draft tube system

An apparatus and method for separating components of a fluid mixture. The apparatus includes a vortex generation zone shaped as an inverse truncated cone, a solids collection zone, a separation zone, one or more fluid inlets, one or more gas inlets, one or more fluid outlets, and one or more gas outlets. Gas is introduced into fluid in the vortex separation zone to facilitate the separation of components of the fluid mixture.

Systems and methods for liquid separation

A wastewater treatment system is provided comprising a biological reactor having a separation subsystem, a suspension system and a membrane operating system. The separation subsystem is constructed and arranged to maintain adsorbent material in the biological reactor with a mixed liquor. The suspension system is positioned in the biological reactor and is constructed and arranged to maintain adsorbent material in suspension with mixed liquor. The membrane operating system is located downstream of the biological reactor and is constructed and arranged to receive treated mixed liquor from the biological reactor and discharge a membrane permeate. In addition, a wastewater treatment system is provided comprising a first biological reaction zone, a second biological reaction zone and a membrane operating system. The first biological reaction zone is constructed and arranged to receive and treat the wastewater. The second biological reaction zone includes a separation subsystem and is constructed and arranged to receive effluent from the first biological reaction zone. A suspension system for adsorbent material is provided in the second biological reaction zone. The membrane operating system is located downstream of the second biological reaction zone and is constructed and arranged to receive treated wastewater from the second biological reaction zone and discharge a membrane permeate.

Suspended media membrane biological reactor system including suspension system and multiple biological reactor zones

The invention is directed to a method and apparatus for treating wastewater. The wastewater treatment system includes a bioreactor including activated carbon and a first biological population. The wastewater treatment system may also include a membrane bioreactor and/or a wet oxidation unit.
