摘要： An apparatus is described for cleaning papermaking felt by applying a low concentration of a cleaning solution through the oscillating needle nozzles. The detergent is applied intermittently while paper is being manufactured. Each cleaning period lasts for at least the length of time required for the nozzles to cover the entire surface of the felt, and preferably twice that period of time. The application of cleaning solution is then discontinued for a period of time. This cycle is repeated continuously as the paper is being manufactured. The apparatus includes a first cleaning chemical reservoir, a second cleaning chemical reservoir, a high pressure pump coupled to the first and second reservoirs, and a control unit having programming for selectively injecting the chemicals.

摘要： A method of forming a paste detergent composition includes forming two separate aqueous solutions. The first aqueous solution includes an effective concentration, generally 1 to 70% of potassium tripolyphosphate. The second solution is an aqueous solution of a water soluble sodium based detergent builder preferably sodium hydroxide. These are combined and due to the effective concentrations of the potassium tripolyphosphate and the water soluble detergent builder, the viscosity of the formed detergent substantially increases relative to either of the viscosities of the first or second aqueous solutions. This provides a unique method of forming paste detergent compositions particularly for use in warewashing machines.

摘要： An aspect ratio flow metering device may comprise a concentrate inlet portion, one or more restricted flow portions of tubing fluidly connected to the concentrate inlet portion, and a metered concentrate outlet portion fluidly connected to the one or more restricted flow portion of tubing. The narrowest part of the one or more restricted flow portions of tubing may each have a length (RL): inner diameter (RID) ratio of at least 10:1. The metered concentrate outlet portion may have an inner diameter (OID) greater than RID. The concentrate inlet portion may have an inner diameter (IID) greater than RID. The aspect ratio flow metering device may be structurally configured to limit flow of a concentrate into a hydrodynamic mixing apparatus. Also disclosed are methods for using the aspect ratio flow metering device to mix fluids.

摘要： A high caustic paste dishwashing detergent is formulated to avoid reversion of the polyphosphates. The composition which includes at least about 35% sodium hydroxide (solids) is formulated with up to 30% of a phosphate sequestering system. The phosphate sequestering system includes preferably equal proportions of tetra alkali metal pyrophosphate and alkali metal tripolyphosphate. The high percentage of pyrophosphate is added to further stabilize the phosphate system. The detergent composition also includes a low molecular weight polyacrylic acid, a phosphono alkyl tricarboxylic acid, colloidal silica and a gluconate and optionally a chlorine source and defoamer. Preferably the composition includes at least about 40% sodium hydroxide, 10% tetra sodium pyrophosphate and 10% sodium tripolyphosphate with the remainder formed from the polyacrylate, phosphono butane tricarboxylic acid, sodium gluconate, colloidal silica, Chloramine T and water.

摘要： Algae growth in an open water system such as a water cooling tower is controlled by reducing the amount of light available for the algae to photosynthesize. The light available for photosynthesis is reduced by incorporating a dye into the water in the water cooling system. Thus the dye absorbs the light necessary for photosynthesis and in turn prevents algae growth. Preferably fluorescein at a concentration of 0.2 to 800 parts per million is incorporated into the water in the water cooling system. Other dyes can be selected depending on the particular algae.
