Abstract
An aerobic microorganism growth medium for use in a wastewater treatment system is formed as a resilient coil of fibrous strand material suspended on a frame placed in a vessel containing the wastewater to be treated.
Claims15
A method for forming and utilizing a microorganism growth structure in an apparatus for treating wastewater, comprising the steps of:
- (a) forming a plurality of fibrous coils, each said coil having a tube surrounding a bendable material of sufficient rigidity to maintain its shape;
- (b) forming a frame having coil support means;
- (c) suspending each of said plurality of coils on said frame between said coil support means;
- (d) establishing a vessel for receiving wastewater to be treated and sized for receiving said frame containing said suspended plurality of coils;
- and
- (e) installing said frame with said suspended plurality of coils in said vessel.

A method for forming and utilizing a microorganism growth structure in an apparatus for treating wastewater, comprising the steps of:
- (a) forming a plurality of fibrous coils, each said coil being formed of a fibrous strand continuously wrapped around a core formed of a jacket surrounding a bendable material having sufficient rigidity to maintain the shape to which it is bent and being bent to establish the shape of said coil;
- (b) forming a frame having upper and lower horizontal support rods and interconnected frame members supporting said rods;
- (c) suspending said plurality of coils on said frame between and supported on said rods;
- (d) establishing a vessel for receiving wastewater to be treated and sized for receiving said frame containing said suspended plurality of coils;
- and
- (e) installing said frame with said suspended plurality of coils in said vessel.
