NOVELTY - The system (2) has a rotatable helical shaft rotatably couplable through a drive port (14). A motor (22) is coupled to the helical shaft for rotating the helical shaft to separate waste, and translate waste toward an extraction port (12). A computer (26) is connected to a waste content sensor, the motor and a waste extractor (20), and stores data to correlate waste content sensor readings to a waste content level such that rate of waste extraction is controlled by the computer to maintain the waste content level below a set-point for providing outgoing stream (4) with low waste content.    USE - Waste filtration system for separating and filtering waste content in waste stream i.e. municipal sewage and industrial waste storage or stream, in a geothermal heat exchange loop for heat recovery from a waste storage tank and a direct refrigeration heat exchange loop for cooling from the waste storage tank in municipal structures, apartments, office buildings and industrial facilities.    ADVANTAGE - The system realizes waste stream filtration with dynamic control of waste content level for heat recovery systems and continuous dynamic extraction of waste from the waste stream in a closed loop sealed system, and maintains waste content level for heat recovery so as to achieve precision control of waste extraction from the waste stream at low content levels. The system has self-cleaning features to manage fibrous or large waste, and realizes extended use before replacement of parts and improves significant performance of heat exchange systems from recovered heat from previously challenging to extract stream effectively from a source of continuous heat. The system receives fluid stream and safely and efficiently processes, filters and effectively separates the waste for remixing the waste for closed loop so as to reduce viscosity and solid content of an outgoing filtered stream without effecting heat content of the waste stream, so that the filtered stream can be used for heat exchange or recovery. The system realizes automated removal over range of waste content and self-cleaning automation, thus avoiding the need to perform manual cleaning or stopping process. The system controls macerator operation optionally to last extended or minimum period if triggered so as to improve automation and reduce maintenance by conditioning incoming waste stream to remain within acceptable parameters. The system filters waste water in an efficient, effective and integrated manner, controls displacement pump extraction rate by speed sensing of the auger and provides a closed processing loop for waste extraction and replacement.    DETAILED DESCRIPTION - The motor is a variable speed motor and a geared motor. The waste content sensor is a direct mechanical load sensor (33). The waste extractor is a displacement type pump selected from a group of lobe pumps, progressive cavity pumps, vane pumps and gear pumps. The rotatable helical shaft is an auger (18). An INDEPENDENT CLAIM is also included for a method for extracting waste and filtering a waste stream.
