Abstract
A wastewater trickle tower has at least one biomedia grate including pairs of upper hanger bars, pairs of lower hanger bars, and spaced-apart rows of biomedia strands, preferably looped cord strands, connecting the upper and lower hanger bars. Upper ends of the strands are secured between pairs of the upper hanger bars, and lower ends of the strands are secured between pairs of the lower hanger bars. A base receptacle to collect wastewater is disposed below the grate. The upper hanger bars are secured together as a unit, the lower hanger bars are secured together as a unit, and a tensioning arrangement is provide for tensioning the strands by influencing the upper and lower hanger bars apart.

A wastewater treatment apparatus, comprising:
- a support structure;
- a trickle tower supported by said support structure and containing biomedia;
- said biomedia being in the form of at least one grate comprising a plurality of hanger frames;
- each hanger frame comprising a row of vertically extending biomedia strands, a pair of mutually connected upper bars, and a pair of mutually connected lower bars, upper ends of the strands of the row being clamped between the pair of upper bars, and lower ends of these strands being clamped between the pair of lower bars;
- the upper bars of said grate being connected together, the lower bars of said grate being connected together, and the respective rows of strands being spaced apart;
- and
- said upper bars being suspended from said support structure and said lower bars being anchored below said upper bars with the rows of strands being tensioned between said upper and lower bars.
A biomedia filter unit for incorporation in a trickle tower wastewater treatment apparatus, said filter unit comprising:
- a grate comprising a plurality of hanger frames, each hanger frame comprising a row of spaced-apart biomedia strands;
- each frame further comprising a pair of mutually connected upper bars and a pair of mutually connected lower bars, upper ends of the strands of a respective row being clamped between the upper bars and lower ends of these strands being clamped between the lower bars;
- and
- the rows of biomedia strands being spaced apart with the upper bars of the grate being connected together and the lower bars of the grate being connected together.
A wastewater trickle tower apparatus, comprising:
- at least one biomedia grate comprising upper hanger bars, lower hanger bars, and spaced-apart rows of looped cord biomedia strands connecting said upper and lower hanger bars;
- upper ends of said strands being secured by said upper hanger bars, and lower ends of said strands being secured by said lower hanger bars;
- a base receptacle below said grate;
- said upper hanger bars being secured together as a unit;
- said lower hanger bars being secured together as a unit;
- and
- at least one adjustable member slidably mounted relative to the receptable for drawing one of said lower or upper hanger bar units away from the other.
