Flow trap with compartment separator and baffle for use in a water-free urinal

A urine cartridge comprising:

• an inlet compartment for receipt of urine;
• an outlet compartment for transfer of the urine from said inlet compartment to an external drain;
• fluid contained within said compartments;
• and
• a mechanism between said inlet and outlet compartments effecting a channeling media of least resistance through any solid matter deposited therebetween, said mechanism including an uneven configuration which increases the flow velocity of the fluid and avoids the resistance of flow due to any deposits on a portion generally within the region from said inlet compartment to said outlet compartment, so that the increased velocity thus effects channels of least resistance through any solid matter deposited in the region between the inlet and outlet compartment.

A cartridge for handling wastewater comprising:

• an inlet compartment for receipt of wastewater;
• an outlet compartment coupled to an external drain;
• a path coupling said inlet and outlet compartments for transfer of the wastewater from said inlet compartment to the external drain;
• and
• a mechanism between said inlet and outlet compartments having media directing the wastewater in multiple paths of varying velocity within said coupling path towards said outlet compartment and effecting at least one channel of least resistance between said inlet and outlet compartments.

A wastewater trap having

• an inlet compartment for receipt of fluids including urine,
• a sealant floatable on the fluid in the inlet compartment,
• an outlet compartment for transfer of the fluids from the inlet compartment to an external drain, and
• a separator separating said inlet and outlet compartments and having a bowed wall.

A wastewater trap comprising:

• an inlet compartment for receipt of wastewater;
• an outlet compartment for transfer of the wastewater from said inlet compartment to an external drain;
• fluid contained within said compartments;
• a sealant floatable above the fluid contained within said inlet compartment;
• and
• a separator separating said compartments;
• and
• a baffle between said inlet and outlet compartments.

A wastewater trap comprising:

• an inlet compartment for receipt of wastewater;
• an outlet compartment for transfer of the wastewater from said inlet compartment to an external drain;
• fluid contained within said compartments;
• a layer of sealant floatable above the fluid contained within said inlet compartment;
• and
• a separator separating said compartments into substantially equal volumes.

A urine cartridge comprising:

• an inlet compartment for receipt of urine;
• an outlet compartment for transfer of the urine from said inlet compartment to an external drain;
• fluid contained within said compartments;
• and
• a sealant floatable above the fluid contained within said inlet compartment;
• and
• a separator separating said compartments into substantially equal volumes for enabling the pressures in said compartments to be substantially equal, the substantially of the equal volumes between said two compartments being effective to militate against syphoning of the sealant from said inlet compartment to said outlet compartment and, thereby, to militate against premature failure and a reduction in the usable life of said cartridge.
