[0053] HOCL (hypochlorous acid) is an endogenous substance in all mammals and is effective against a broad range of microorganisms. HOCL made by combining non-iodinated salt, water, and electrolysis. The system reviewed to make HOCL on-site is a 1-liter container that is filled with water to which 1 gram of non-iodized salt and 1 teaspoon of vinegar are added. The system can make concentrations of 50 to 200 ppm (1 ppm equals 1 mg/L) in 8 minutes with a push of a button on a smart HOCL machine.
HOCL Technical Analysis.
[0054] Hypochlorous Acid (61) (also referred to as electrolyzed water, EW) is an oxyacid of chlorine with formula HOCL. It is a weak acid and highly unstable and can exist in a solution. EW is produced by electrolysis as shown in
[0055] EW is the product of the electrolysis of a dilute NaCl solution 49 in an electrolysis cell, having a semi-permeable membrane 64 that physically separates the anode 50 and cathode but permitting specific ions to pass through.
[0056] The voltage between the electrodes 48 set at 9 to 10 volts during electrolysis. Sodium chloride NaCl 47 dissolved in deionized water 49 dissociates into negatively charged chloride Cl− 52 and positively charged sodium ions Na+ 53. At the same time, hydroxide OH− 54, and hydrogen (H+) 55, ions are formed. Negatively charged ions Cl− 52, and OH− 54, moves to the anode to lose electrons and form 56, oxygen gas O2 56 chlorine gas Cl2 59 hypochlorite ion OCl−, 60 hypochlorous acid HOCl 61, and 62, hydrochloric acids. Positively charged ions such as H+ 55, and Na+, 53, move to the cathode to form hydrogen gas H2, 57, and 63 sodium hydroxide NaOH 63.
[0057] The solution separates into an acidic solution on the anode side of the membrane 64 with a pH of 2 to 6.0, an oxidation-reduction potential (ORP) of ≥1,000 mV, and a chlorine content of 10 to 90 ppm, and a basic solution on the cathode side of the membrane 64 with a pH of 7.5 to 13 and an ORP of ˜−800 to −900 mV.
[0058] The solution from the anode is acidic electrolyzed water (EW) 61 and the cathodic solution known as basic EW. Neutral EW, with a pH of 6 to 7.5 and an ORP of 750 mV, is produced by mixing the anodic solution with OH− ions 54. The solution from the anode is called acidic electrolyzed water, acid oxidizing water, or electrolyzed oxidizing water, and the cathodic solution is known as basic electrolyzed water, alkaline electrolyzed water, or electrolyzed reducing water.
[0059] There are several EW-producing machines available in the marketplace. The effectiveness of hypochlorous acid 61 as an active sanitizing agent is figured out in large part by the pH, a measure of the acidity or hydrogen ion concentration of the solution.
[0060] At an acidic to neutral pH, 6-7.5 pH the predominant chemical is hypochlorous acid HOCl 61, with a high oxidation reduction potential and has received recent attention as an alternative to other chlorine disinfectants and sanitizers.
[0061] Sanitizing means reducing the microorganisms of public health importance to levels considered safe, without adversely affecting either the quality of the product or its safety. EW is as effective as any chlorine treatment and is an alternative to other potentially dangerous chemicals, e.g., chlorine gas 59 chlorine dioxide, and bleach.
[0062] The apparatus to produce EW is inexpensive and easy to operate, because only water and sodium chloride are used. EW production is environmentally friendly, and the properties of the EW can be controlled at the preparation site.
[0063] HOCL Acid 61 has a shelf life of 4 days when exposed directly to sunlight and 14 days when sheltered from sunlight. HOCl Acid 61, can inactivate a variety of viruses including CORONA VIRUSES in less than 1 minute contact time at concentrations of 200 PPM. It can be used in liquid and aerosol forms.
[0064] At a pH of 6.0-7.5 (neutral), EW (ORP=750 mV) holds primarily hypochlorous acid. The effectiveness of neutral EW as a sanitizer has been proven to incapacitate Escherichia coli, Salmonella enteritidis and Listeria bacteria. This is primarily the reason Hypochlorous Acid 61 was chosen as the neutralizing agent for the facility-based wastewater neutralization process.
Characterization of feces and Urine. By C. Rose A. Parker and E. Cartmell. (www.ncbi.nlm.nih.gov)
[0065] Median fecal wet mass production was 128 g/cap/day per unit discharge. Dry Mass of 29.5 g/cap/day. Feces were composed of 74.6% of water or 0.09851 liter of water and 23.4% dry mass or 29.5 grams. Median urine generation rates were 1.42 L/cap/day with dry solid content of 64 g/cap/day. Urine is 91 to 96% water per discharge volume. Dry urine solids are consisting of 58-64 g/cap/day per person. Combined solid waste discharge fecal and urine discharge per person per day is (29.5 g/cap/day/person) and (64 g/cap/day/person). A total of 93.5 g/cap/day/person solid waste matter and (0.09851 liters water from feces and 1.349 liters of water from urine) or 1.4475 liters of reclaimed water.
[0066] The above data shows water and dry mass data collected for unit daily fecal and urine discharge per person. The data shows the volume of water in liters and weight of dry mass fertilizer in grams, recovered per unit daily discharge.
[0067] Analysis of 0.5 million discharges per day or 100,000 facility discharges (average facility consists of 5 persons) to a wastewater treatment plant show:
[0068] Recovered stool discharge waste: 49,250 liters of stool water and 14,750 kg of recovered dry stool to be disposed of daily, plus additional cleaning tissue.
[0069] Recovered Urine discharge waste: 675,000 liters of water from urine and 46,675 kg of solid waste from urine to be disposed of daily.
[0070] Analysis of combined fecal and urine waste disposal for 100,000 widely distributed facility-base units (e.g., single family homes with an average household of 5 member). Daily calculated dispersed disposal of about 467.5 gm of solid waste plus an undetermined amount of toilet paper and other waste residue (fat residue, food particles, soap residues mixed with cleaning tissue) and the addition of 7.24 liters of water per facility to be disposed of daily.
[0071] Analysis: Patent concept establishes an argument that individual facility-based domestic wastewater treatment systems offers a simplified and environmentally sound method of waste accumulation and disposal versus currently used waste water treatment process.
[0072] There are many iterations of the proposed patent concept of a facility-based rapid waste neutralization system. One iteration
[0073] This iteration has a modified toilet 39 which incorporates a motor 42 and driven cutter 40 that uses blender-like action to pulverize the fecal mass, urine, and cleaning tissue. A multitude of grinding and mixing arrangements can be adapted to thoroughly grind and mix contents, chemically treat and also facilitate ease of filtration of wastewater. The toilet 39 is fitted with an anti-syphon ball valve 43 in the syphon discharge tube to prevent the premature discharge of the fecal batch during the cutting process.
[0074] A precise amount of Hypochlorous Acid 61 is added to the flush tank water (not shown). During the flushing process, chemically charged flushing water (100-200 ppm HOCL) neutralizes the fecal charge, sanitizes and deodorizes the toilet 39, cutter blades 42 and the plumbing system.
[0075] The treated charge upon being flushed is transferred via the plumbing lines to process treatment tank 33 where it is mixed with residual utility water contained in tank 33. The below grade process tank 33 cover is fitted with an array of spray nozzles 13 that dispenses a precise charge of hypochlorous acid 61 to the tank walls and contents. A grinder pump 12 is fitted in the base of 33 and it intermittently grinds and recirculates the contents until a discharge signal is sent by the process board. The process board is an electronic programmable controller unit that employs a series of sensors, timers, valves, and controllers to assist with system processing. A fill water level sensor activates the discharge and filtration process and powers water pump 19 supplying recovered water from tank 21 to assist with the filtration process. Normally opened solenoid valve 14 is closed, and normally closed valve 15 is opened allowing treated wastewater discharged to filters 23, 24 & 25 to be separated into recovered water and slurry waste.
[0076] A calculated amount of recovered water is supplied from storage tank 21 (suggested 30 gallons, computed on pump flowrate and pump operating time, controlled by the process timer) via circulating pump 19 to process tank 33 to aid with the thorough filtration of treated wastewater which is separated into recovered wastewater and slurry waste. Recovered wastewater is sent to storage tank 21 and the excess recovered wastewater is sent to disposal medium 32 or to transfer pipe 31.
[0077] The recovered stored wastewater can be used directly from the tank 21 as toilet flush water, irrigation lawn water, or for pool make up water. Additionally stored recovered water can be processed through an on-demand UV, treatment system 22; water to be reused for laundry and outside house use such as car washing etc. The recovered water can also be processed through a Reverse Osmosis Machine 34 to reclaimed water status for inside house usage such as showering, and kitchen uses. Backwashed slurry waste is sent as to slurry waste tank 26 for further treatment and disposal.
[0078] A simple method of disposal of wastewater slurry waste is to pump/spray the waste into a perforated basket and allow the wastewater to drain, leaving a residue mixture of grounded toilet paper mixed with fecal and urine solids, food remnants and undissolved fats and soap remnants. This residue can be used wet or dried as a soil amendment. Hypochlorous Acid 61 is a sanitizer and disinfectant that will eliminate odors from the solid waste residue.
[0079] Another iteration is a standard toilet mounted upon rectangular process box 65 equipped with a grinder motor 12, to pulverize the process batch mixed with a precise amount of Hypochlorous Acid 61 to neutralize the harmful pathogens and bacteria and discharged via discharge valve 43.
[0080] In each iteration the chemical metering pump 17 dispenses a fixed amount of chemical to a volume of flush water within the system to serve as the primary neutralizing agent necessary to kill harmful bacteria and to sanitize and deodorize the toilet bowl, cutting blades plumbing lines and process tank.
[0081] The system uses a secondary process tank 33 to chemically treat and neutralize processed and unprocessed wastewater sent to the tank. The tank cover is equipped with an array of spray nozzles 13 and dispenses a precise chemical charge to the tank and contents. A grinder pump 12 is fitted in the base of the process tank 33 that grinds the process batch for a programmed amount of time based on timer settings and recirculates contents via a normally open solenoid valve 14 to the process tank. Process batch contents are ground to a fineness of about 300-500 microns and then discharged via normally closed solenoid 15 valve to filtration units 23, 24 & 25.
[0082] The system is equipped with a recovery storage tank 21 that stores recovered water. During the discharge to the filtration units 23, 24 & 25 the normally closed discharge solenoid valve 15 opens and simultaneously circulating water pump 19 transfers water from the recovery storage tank 21 to the process tank 33 to ensure the treated wastewater is thoroughly filtered.
[0083] All filters will be backwashed after each process discharge from process tank 33. The backwashing of filters thoroughly unclogs and chemically treat filter media.
Membrane filters are soaked with wastewater containing 100-200 ppm of HOCL Acid. This wetness of membrane filters reduces the need for quarterly chemical treatment with citric and or hydrochloric acid as per chart in
[0084] In yet another aspect
[0085] Separate black wastewater processed as shown in
[0086] In another iteration
[0087] 100% of the recovered gray water stored into a separate storage tanks 21 to be reclaimed to potable standards using a combination of Reverse Osmosis process 34 UV, treatment 22 and Ozone treatment 36. The backwashed content is sent to the slurry waste tank 26 for storage, processing and disposal.
[0088] Recovered water stored in tanks can be for irrigation purposes. Some of the recovered water can be stored in another tank designated for reverse osmosis treatment and be reused as laundry water, toilet flush water, swimming pool water and outside house water.
[0089] In another aspect, commercial facility based rapid waste neutralization systems can include separate plumbing lines for new constructions, with separate plumbing arrangements and connections to different processing machines as needed. Also, system can be configured to use multiple modified toilets, secondary process tanks, HOCL machines, filtration units, storage tanks and waste processing tanks as needed to satisfy differing processing capacities.
[0090] In yet one other aspect, the facility-based wastewater recovery system can include at least one of a plurality of filtration units having a polyvinylidene difluoride membrane filter (PVDF) 24 to remove chemical waste such as perchloroethylene, sometimes found in laundry wastewater, and waste discharges from other plumbing units in a facility and the removal solid particulates having an effective diameter of 0.01 microns or greater.
[0091] In still one other aspect, the facility-based wastewater reclamation system may have multiple spin down filters 23 from 40 um to 90 um to help separate the cleaning paper fibers and allowing recovered water free of fibers to enter the membrane filters effectively removing bacteria and other fecal particles less than 0.01 micron.
[0092] In yet another aspect filtration unit can include ceramic flow through nano filter to further remove bacteria and solids up to a fineness of 0.01 micron.
[0093] In another iteration any array of CTO filters can be installed to treat and enhance the color, odor and taste of reclaimed gray water.
[0094] In yet another aspect, the facility-based wastewater reclamation system can include a Reverse Osmosis unit 34 to remove free ions and other contaminants contained in the amount of recovered and reclaimed wastewater dispensed from on-demand ozone unit 36 as drinking water.
[0095] In at least one embodiment
[0096] In another embodiment shown in
[0097] As will be further appreciated, the present system may be installed in new construction as shown in
[0098] In another iteration the above-described process can be adapted to multifamily domestic residences. In this iteration multiple process tanks and modified toilets with large HOCL Acid producing machines are needed to process the larger discharge capacities because of the increased number discharge outlets. Considerable design analysis to accommodate the new capacity is necessary to successfully process the increased wastewater capacity. This can be successfully done at a cheaper cost and safely process the new designed capacities.
[0099] Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
[0100] Furthermore, it is understood that any of the features presented in the embodiments may be integrated into any of the other embodiments unless explicitly stated otherwise. The scope of the invention should be determined by the appended claims and their legal equivalents.
[0101] Benefits of the combined embodiments includes water conservation without restricting water usage, reduction of freshwater demand thereby alleviating the impacts of drought, providing additional water availability for use in firefighting efforts, agricultural and manufacture usage, minimizing if not ultimately eliminating altogether the need for sewage transmission lines and municipal wastewater treatment facilities.
The reduction of and possible elimination of raw sewage discharges, sanitizing, disinfecting, and eliminating foul odors associated with facility plumbing system and sulfur gas discharges associated with water treatment plants. The recharging of groundwater reserves, and a significant reduction in the manufacture, and subsequent disposal, of plastic drinking water bottles by increasing the availability of reclaimed water for potable water usage, just to name a few.
[0102] Finally a facility base rapid wastewater treatment process that offers real world solutions comprising: [0103] a. An outcome for the reduction of water borne pathogens and spread of infectious diseases, resulting from chemical neutralization of pathogens at the source and the reduction of sewers and septic collectors globally. [0104] b. An outcome curtailing environmental contamination of water bodies resulting from intended wastewater reuse and disposal methods globally. [0105] c.
