An automated waste water treatment system includes a collection tank constructed to hold waste water, a first flow line connected to the collection tank to output the waste water from the collection tank, an electrocoagulation unit that receives the waste water and outputs the waste water as coagulated waste water, a polymer dosage tank to provide a polymer dosage to the coagulated waste water to produce and output flocculated waste water. An air grid of the electrocoagulation unit, the latter housing a plurality of electrodes, increases the lifespan and efficiency of the electrodes to perform electrocoagulation of the waste water. A clarifier connected to the flow line receives the flocculated waste water and produces sludge-free waste water and concentrated sludge, a series of filters to output filter-treated water, and an ultrafiltration system that receives filter-treated water and outputs ultrafiltration-treated water to a reverse osmosis system.

The present disclosure comprises devices, systems and methods for the removal of a precipitate from a surface of a water treatment chamber using a dasher assembly having two cylindrical actuator rods connected to a dasher for scraping an interior surface of the water treatment chamber. The water treatment chamber has an enclosed first end, an enclosed second end, and an electrolysis rod extending linearly therein. The two cylindrical actuator rods extend linearly within the water treatment chamber and pass through the enclosed first end so that portions of the two cylindrical actuator rods are within the water treatment chamber and portions are outside the water treatment chamber. The dasher includes an aperture therethrough so the electrolysis rod can pass through the aperture and allow the dasher to translate from a first location and a second location by translation of the two cylindrical actuator rods via a mechanical actuator. The dasher may include teeth extending from an outer edge of the dasher to score the precipitate as it translates from the first location to the second location. The dasher assembly is controlled manually and/or by an automated control system.

A thermal disinfection system and a method to perform a thermal disinfection procedure of fluid lines of a medical apparatus are disclosed herein. In an example, the thermal disinfection procedure comprises at least the steps of receiving a temperature signal from a temperature sensor, determining a measured temperature value of a fluid within a hydraulic circuit, receiving a pressure signal from a pressure sensor, determining a measured local atmospheric pressure value, and driving a heating unit to heat the fluid based on the measured temperature value and the measured local atmospheric pressure value.

A device for sterilizing fluid waste to render said waste noninfectious, said device comprising a U-shaped conduit means, a pump, and a heating means, wherein the conduit means is oriented vertically so that fluid moving through it is subjected to higher pressures at the bottom of the loop, heat is applied to fluid at the bottom of the loop by the heating means, and the pump moves the fluid through the conduit means at a flow rate that ensures sufficient heat is applied to the fluid for a sufficient period of time.

A fluid sterilization device according to an embodiment includes a tubular portion; a supply head provided in one end portion of the tubular portion; a discharge head provided in the other end portion of the tubular portion, and including a hole penetrating through the discharge head between an end face on a tubular portion side and an end face on a side opposite the tubular portion side; a substrate provided inside the hole of the discharge head; a light-emitting element provided on a surface on the tubular portion side of the substrate, and configured to emit an ultraviolet ray; and a window provided in the discharge head, and facing the light-emitting element. A surface roughness Ra of an inner surface of the tubular portion is 50 nanometers (nm) or less.

Process for treating sludge includes a first segment in which a batch of sludge and lime are mixed with the addition of supplement heat to achieve an elevated processing temperature and a second segment in which the mixer is maintained at a lower temperature to dry the interior of the mixing device after processing the batch.

A small sewage treatment plant comprises a first sewage tank in which a preliminary clarification takes place due to the sinking of solid particles to the bottom of the first sewage tank, and a filtering device in a second sewage tank, which filtering device comprises several filters and to which the pre-clarified sewage is fed from above for further clarification. The filtering device has a rotary plate which is rotatable about a vertical axis of rotation and stores several filter containers, each filter container including several filters arranged above each other. In a lid of the second sewage tank, a closable tank opening is provided, via which at least one filter is removable when the associated filter container is opposite to the tank opening after a corresponding rotation of the rotary plate.

A dosing pump (19) doses antiscalant into a membrane-based water treatment system (1). The dosing pump (19) includes a displacement body for pumping antiscalant into the membrane-based water treatment system (1) in doses. A motor drives the displacement body. A control module controls the motor. The control module is configured to vary the dosage of antiscalant pumped into the water treatment system (1) based on a temperature corrected system variable (SVTc) being based on a plurality of operating variables of the water treatment system (1).
