A method and system for operating a seal gas compressor utilized in a direct reduction process including: monitoring a pH level of a water stream used in the seal gas compressor, wherein the pH level of the water stream is affected by a reformer flue gas stream that comes into contact with the water stream, wherein the monitoring step is carried out one or more of upstream of the seal gas compressor and downstream of the compressor; and adjusting the pH level of the water stream to maintain the pH level of the water stream within a predetermined range based on feedback from the monitoring step. The method includes maintaining the pH level of the water stream upstream of the seal gas compressor in a range between 7.5 and 10 and maintaining the pH level of the water stream downstream of the seal gas compressor in a range between 7.8 and 9.5.

Technologies are generally described for an apparatus configured to process a volume of a fluid and provide an electrolyzed fluid. Example apparatuses described herein may include a base cell, electrodes and/or a variable expansion cell. The base cell may be configured to contain at least a portion of the volume of the fluid. Electrodes may include an anode and a cathode. The electrodes may be configured to be mounted within the base cell. The variable expansion cell may be coupled to the base cell, and adjustably configured to change a volumetric space of the apparatus to accommodate the volume of the fluid such that the electrodes are substantially immersed in the fluid.

The invention provides methods and compositions for reducing the amount of water required in an industrial process, especially a bottling process such as beer or beverage manufacturing. The method comprising the steps of: collecting water used to rinse cleaned and/or dirty recycled bottles, spraying the collected water at a food contacting piece of equipment as part of a CIP rinse, and passing the CIP second rinse water into a cooling tower as make-up water. The method allows for the re-use of water already in the system but by being careful where each water stream goes the water does not accumulate contaminants that would damage the cooling tower or foul the bottled product or vessel that is cleaned by CIP method.

The invention relates to a method and a device for treating foods and/or containers for holding foods. The foods and/or containers are treated in at least one treatment zone by a process liquid, wherein the process liquid is at least partially recirculated into the treatment zone or the treatment zones after completed treatment of the foods and/or the containers. At least one membrane filtration system and at least one UV irradiation apparatus are provided for cleaning and sterilisation of the process liquid.

A water quality converter includes: a container having an oval hollow, where the container is a plastic body of a mixture in which 10% to 30% by weight of aventurine, 5% to 20% by weight of sodalite, 2% to 10% by weight of amethyst, 1% to 10% by weight of Chungito, 5% to 20% by weight of germanium, 2% to 10% by weight of Shungite, 3% to 10% by weight of elvan, 2% to 10% by weight of rose crystal, 1% to 5% by weight of seven-colored gemstone, and 1% to 5% by weight of wooden stone are mixed, and a weight ratio of aventurine to sodalite ranges from 3:1 to 1:1, a weight ratio of aventurine to germanium ranges from 2:1 to 1:1, a weight ratio of germanium to Shungite ranges from 4:1 to 1:2, and a weight ratio of amethyst to germanium ranges from 1:2 to 1:5.

A filtration system for a pet water fountain is provided. The filtration system utilizes a pump placed within or along a watering bowl. The water filtration system also utilizes a multi-stage filtering device. In one aspect, the multi-stage filtering device includes a first filtering stage representing copper zinc alloy particles, and a second filtering stage representing granulated activated carbon particles. Each stage may constitute filtering material that is separated into an array of cells residing along a vertical frame or is separated into stages placed in series within a tubular cartridge. A method for filtering water in a pet fountain is also provided herein.
