摘要:
Water treatment products designed for use in cleaning machines such as dishwashers or laundry washers are disclosed. The water treatment products are in the form of a water semi-permeable pouch comprising a water treatment composition which may include a water treatment composition such as citric acid. Additionally, rather than putting the semi-permeable pouch directly in the cleaning machine, the pouch may be housed in a canister though which water added to the machine passes. Methods for treating water in cleaning machines using the water treatment products are also disclosed.

The present invention describes a deodorant for treating sediment in-situ, the deodorizing method and the associated facilities. The deodorant is a calcium nitrate solution with a mass percentage of 14.32% to 52.49%. The deodorizing method comprises the following: (a) Determining acid volatile sulfides content and total organic carbon content of sediments to be deodorized, and then calculating the dosage of calcium nitrate solution required for deodorization; (b) Ploughing the bed of the treatment area by injection tines of a bioremediator; and at the same time, injecting calcium nitrate solution into the sediment; and after the bioremediator has navigated forward, the trench sides of the ploughed furrows will collapse, thus encapsulating the calcium nitrate solution within sediment. The facilities for deodorizing sediment in-situ are bioremediator(s) which comprise 4 systems, namely an injection system, a storage system, two supply systems and a navigation system. The present invention utilizes a bioremediator to inject calcium nitrate solution into sediment so that those organic pollutants producing bad odor will be degraded by the help of the calcium nitrate to harmless and odorless gases. The present invention will further solve the problems associated with the current practice of environmental dredging, namely that land and spaces will have to be occupied and secondary pollution will be caused due to dredging of sediment and their subsequent disposal.

A solid zeolite free soluble water softening composition comprises an effervescent system including an organic acid and an alkali which react together upon dissolution in water.
摘要:
A novel series of compositions with aqueous chemicals decontamination activity and their uses is described. The preparation of esters of fatty acids with polyols that contain lactic acid is also described. These novel compositions release hydroxy acid and fatty acids slowly into water providing activity over long periods of time with the compounds exhibiting biodegradable characteristics and aiding in the biodegradation of contaminants.
摘要:
The present invention relates to a compacted solid product for water purification comprising:—at least a first layer comprising at least a coagulant/flocculant system comprising at least one polyvalent inorganic salt, at least one water-soluble cationic polymer and at least one high-molecular-weight anionic polymer,—at least a second layer comprising at least one disinfectant that releases active chlorine on contact with water, characterized in that said coagulant/flocculant system moreover comprises a sodium alginate. The invention also relates to the method for preparing such a product.
摘要:
The PAM delivery product is a solid form of polyacrylamide polymer (PAM). Among other things, the PAM delivery product can be used to prevent ruts formed during center-pivot irrigation, prevent erosion of irrigation ditches, clarify wastewater, and assist seed germination and seedling establishment. The PAM delivery product includes pure PAM and water to create a solid “loaf.” Water-soluble calcium (Ca) can also be added to the PAM delivery product depending on the specific application for the PAM delivery product. When Ca is used in the PAM delivery product, it is present in a 9:1 ratio to the PAM There are no fixing agents needed in the PAM delivery product; it is pure active ingredient.
摘要:
A microbiological culture for triggering microbiological processes in bodies of water, soils, sediments, and/or muds contains chemo-lithoautotrophic bacteria that are immobilized. The bacteria are immobilized in a matrix having the form of capsules, gels, or gel spheres. The matrix material is selected from a wide range of natural and synthetic polymers.
摘要:
A series of devices, methods and compounds for dosing corrosion inhibitors and cleaners to closed loop systems, boilers, towel rails, heat exchangers and heat stores. The devices and materials can be designed to allow corrosion inhibitors and cleaners to be built into boilers, radiators, heat stores, and any other similar devices. The chemicals are either bound into a gel or dissolved within the crystal lattice of a phase change compound. It is possible to design materials that will rapidly release the chemicals at elevated temperatures. These materials allow cold water flushing of systems without releasing the chemicals. The devices can also be modified to incorporated softening resin to remove the hardness from the system water and thereby prevent scaling.
摘要:
A process for treating a reverse osmosis membrane with a biocide to kill bacteria on or in the vicinity of a membrane by contacting a reverse osmosis membrane with a halogen biocide in combined form which slowly releases halogen in a sufficient amount to disinfect the membrane and to kill any bacteria and thereby eliminate or prevent forming a biofilm on said membrane.
摘要:
A drainage slime remover capable of spreading a solution of a solid over slime generated wall surface portions, comprising a solid containing a microorganism growth retarding substance and a container which has a shape for permitting the installation thereof at the inlet or upper portion of a drain outlet and stores the solid, characterized in that the container has drain flow-in holes having an opening capable of controlling a drain flow-in amount and provided in the upper surface or the upper side portion of the container and solution flow-out holes having an opening capable of controlling a flow-out amount if a solid solution and provided in the bottom or the lower side portion of the container or additionally in the side surface thereof; and a slime preventing/removing agent which can remove slime from portions such as kitchen sinks and bathroom drain outlets where slime is grown by metabolites such as miscellaneous germs and mildews and which can prevent the occurrence of slime safely and for an extended period of time.
