A septic system is provided that includes a septic tank having a plurality of compartments with a tank inlet in a first compartment. First and second vaults are positioned in a second compartment. The first vault receives fluid from the first compartment at a level near a fluid surface in the tank. A first flow inducer receives fluid from the first vault at a level near a bottom of the first vault, and releases fluid into the second compartment at a level near the fluid surface. The second vault receives fluid from the second compartment at a level near a bottom of the second vault and discharge fluid at a level near the fluid surface. Third and fourth vaults and a second flow inducer are positioned in a third compartment, the third vault receiving fluid from the second vault, and the fourth vault discharging fluid to a tank outlet.

A handheld sanitizing device may include a housing with a first end and a second end. The housing may enclose a first cavity and a second cavity. A sanitizing light may be disposed at the first end of the housing. The sanitizing light may be configured to kill biological contaminants. A removable cap may attach to the first end and may cover the sanitizing light. An extendable agitator may extend from the first end of the housing and retract into the first cavity. A motor disposed in the first cavity may actuate the agitator. The agitator may be configured to stir a fluid. The housing may be configured to sit in a mouth of a container, extend into a reservoir of the container, and rest on the mouth of the container. A charging port may be disposed on the housing and electronically coupled to the motor and/or the sanitizing light.

An apparatus for preparing and dispensing a flocculant solution to dewatering an aqueous process stream includes a mixing pump, a maturing tank, and a feeding unit. The mixing pump mixes the flocculant solution and builds up a pressure onto the flocculant solution. The maturing pressure tank is fluidly connected with the mixing pump, so that the pressurized diluted flocculant solution is led from the mixing pump into the maturing pressure tank and matured therein under pressure that is above atmosphere pressure.

An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.

A fluid sterilizing device includes a first reaction chamber, a second reaction chamber, a communication chamber and a light source. The first reaction chamber is connected to a fluid inlet. The second reaction chamber is connected to a fluid outlet. The communication chamber is connected the first reaction chamber with the second reaction chamber. The light source is configured to emit sterilization light to enter the first reaction chamber and the second reaction chamber. The fluid inlet allows a fluid to enter the first reaction chamber, the communication chamber allows the fluid to pass through and enter the second reaction chamber, and a flow velocity distribution of the fluid in the second reaction chamber is different from that of the fluid in the first reaction chamber.

For storing supercooled water, a method cools a water flow with a specified mass flow rate to a specified temperature to form a supercooled water flow. The method conducts the supercooled water flow through a flow pipe with a specified pipe impedance to an ice tank. The method stores the supercooled water flow as ice in the ice tank.

The invention relates to a bioactive filter for the disinfection of liquids, in particular water or aqueous solutions in containers. A structure that is advantageous in terms of filter efficiency is obtained by forming a spherical or oval filter body (1), which is coated with noble metals (FIG. 1).

Systems and methods for controlling a chloramine synthesis reaction. The system includes at least one water pump configured to deliver a first water stream to a first junction where the first water stream is mixed with a first solution including an ammonium compound, and a second water stream to a second junction where the second water stream is mixed with a second solution including hypochlorite, a reaction chamber downstream of the first and second junctions which is configured to mix the first and second water streams in order to react the ammonium compound and the hypochlorite to form chloramine, an optical measurement device disposed upstream of the second junction, the optical measurement device configured to measure an absorbance of the hypochlorite in the second solution, and at least one controller programmed to determine a concentration of the hypochlorite in the second solution based on the measured absorbance.

A thickener for dewatering fluids having a vessel with a central well extending proximate a top portion of the vessel to a lower cone-shaped portion, a hindered settling zone, and a compressible sediment layer zone within the lower cone-shaped portion. Eductors housed in inlet wells have an inlet nozzle and a mixing tube to receive slurry to be treated and clear fluid to be mixed with the slurry. The fluid from the eductors is directed in counter circular paths via circular chambers situated proximate the inlet wells, such that fluid flowing in each direction collides and forms turbulence within the central well. Resultant fluid is directed into a lamella-type separator circumferentially located about a portion of the central well, having layered fluid paths directed radially outwards from said center longitudinal axis and upwards towards said vessel top portion through a conical, inclined fluid path, plate structure. The eductors are adjustable with a movable iris for limiting the amount of clear fluid exiting the eductor.
