摘要:
The Facility comprises a tank for the reception of crude water (1), at least an intermediate tank (2), primary (3), secondary (4) and tertiary (5) conditioners, together with an equipment for the treatment of mud, others for the metering of reactive agents, and a laboratory equipment. In the tank (1), the crude water (9) is subjected to a decantation, precipitation and chemical flocculation process, in the intermediate tanks (2) traces of oils and greases are eliminated and by means of the conditioners, the water is filtered, decalcified and oxygenated. The Facility allows 90-95% of the water employed to be reused, does not produce drainage and the mud is extracted in mineralized form, due to which it does not cause any detrimental effect to the Environment.
摘要:
The water of a water system is treated to inhibit corrosion of metal components by passage through an anion exchanger preloaded with corrosion-inhibiting anions. A low molecular weight polymer is added. A chlorine containing slime controlling agent is added. The concentration of the chloride ion in water is maintained below 50 mg/L.
摘要:
A method and apparatus for treating a liquid (2) to inhibit growth of living organisms therein by adding to the liquid an active biocidal ingredient formed by mixing an oxidant (4) and an amine source (6), by: producing a predetermined dilution of the oxidant (4); producing a predetermined dilution of the amine source (6); synchronously metering the two dilutions into a conduit (16) to continuously mix therein according to a predetermined ratio to produce the active biocidal ingredient having high reproducibility, stability and efficacy in situ in the conduit (16); and continuously injecting the active biocidal ingredient, as it is produced in situ in the conduit (16), directly from the conduit into the liquid being treated.
摘要:
A novel method and compositions are disclosed for the treatment of water in recirculating water systems. The method includes providing a boron level of at least 20 ppm in the water, continually eroding into the water a compressed sanitizer/algicide component including a halogen source material, a boron source material, and glycoluril, and periodically adding to the water an oxidizing clarifier comprising a chlorine source material, a non-halogen, chlorine source material, and a boron source material. The invention also provides novel water treatment chemicals including the compressed sanitizer/algicide component and the clarifier useful in the foregoing system. The system and compositions are safe and reliable, control algal and fungal growth and generally provide improved water quality for recirculating water systems.
摘要:
A method and apparatus for purifying water by the active carbon regeneration system. Contact of tap water with active carbon fibers having a narrow pore distribution and excellent adsorption velocity enables adsorption and removal of residual chlorine, harmful trihalomethanes, and odoriferous substances such as 2-methylisoborneol and diosmin contained in tap water. The use of active carbon fibers having a median pore diameter of about 1.8-3.0 nm, preferably, about 2.0-2.7 nm enables odoriferous substances having large molecular weights to be exhaustively and selectively adsorbed by the carbon fibers. At any time when out of use, the carbon fibers are heated to 100-120 DEG C, whereby the adsorbed trihalomethanes are desorbed and the fibers recover the capacity of adsorbing trihalomethanes. Thus the carbon fibers can, even in a limited quantity, adsorb trihalomethanes and odoriferous substances for long without the necessity for exchanging active carbon fiber cartridges.
摘要:
A manually operable water purification system which includes (i) a first container divided by a filter into a first chamber for retaining contaminated water and a second chamber retaining a porous body of biocidally effective material, and a plunger sealably receivable within the first chamber for forcing contaminated water retained within the first container through the filter and the porous body of biocidally effective material. The filter permits passage of smaller microbiological pathogens which may be effectively chemically controlled, such as bacteria and viruses, while preventing passage of larger microbiological pathogens which are difficult to chemically control, such as cysts.
摘要:
An electrolytic process and apparatus is disclosed for oxidizing or reducing inorganic and organic species, especially in dilute aqueous solutions. The electrolytic reactor includes an anode and cathode in contact with a packed bed of particulate ion exchange material which establishes an infinite number of transfer sites in the electrolyte to significantly increase the mobility of the ionic species to be oxidized or reduced toward the anode or cathode, respectively. The ion exchange material is cationic for oxidation and anionic for reduction, or a combination of both for special circumstances. Preferably, the ion exchange material is treated to convert a portion of the transfer sites to semiconductor junctions which act as mini anodes, or cathodes, to significantly increase the capacity of the reactor to oxidize or reduce the species to be treated. Exemplary applications for the disclosed electrolytic process and apparatus are the conversion of halides to halous acids in dilute solutions.
摘要:
A water purifier comprising an electrolytic cell (30) housed in an enclosure (34) and an attaching apparatus (16). The enclosure (34) attaches over an outlet fitting of a water circulation line in a swimming pool by the attaching apparatus. The attaching apparatus (16) and the enclosure (34) define apertures and outlet openings (38,39), respectively, having increasing areas in the direction of the water flow. This configuration increases flow rates through the apertures and outlet openings (38,39); the increased flow rates break off scale formations extending into the center of the apertures and outlet openings (38,39) and thereby prevent scale from clogging the purifier.
