Abstract: A component filter device which is added to a new or existing multi-chamber septic tank to filter the effluent of the septic tank to improve the quality of the water entering a method of dispersal. The device uses a spiral wound membrane filter to filter the effluent. The membrane filter contains open channel spacers to channel the bubbles which scour the membrane leaves. An air lift pump is used to pump permeate. A three-way actuator valve directs the airflow to either the pump or to a bubble diffuser. A two-way actuator valve directs the flow of permeate. A low water indicator directs the operation of the device. The device uses bubble scouring and back washing to clean the membrane leaves. A blower, two actuator valves and a low water indicator are the only moving parts of the device.

Abstract: A modular wastewater clarification device that may be positioned external to a septic tank or, alternatively, installed internally within a septic tank chamber to produce sufficiently clean water for lawn and agricultural uses. The modular clarification device includes a filter having a smaller size than the pre-filter bridging between the primary and secondary chambers of a septic tank. In one embodiment, the modular filtration unit resides outside the two-chambered septic tank and receives pre-filtered septic tank effluent fluids stored in the secondary chamber that has accumulated pre-filtered effluent. In another embodiment, the modular wastewater clarification device resides inside the secondary chamber and filters the accumulated pre-filtered effluent.

Abstract: An artificial Christmas tree 10 having several branch segment assemblies 14-18 is disclosed, and further having electrically activated lights 46, 48, and 50 which are predisposed or preassembled upon the tree. Also disclosed is a method for automatically winding or placing the lights upon tree 10.
