Abstract: A method of providing a concentrate of a dissolved substance for producing a dialysis solution includes providing a container containing a solid to be dissolved, supplying water into the container for dissolving the solid, draining the concentrate of the dissolved substance from the container and topping up with water, measuring the concentration of the dissolved substance or of a parameter correlated with the concentration, and temporary or permanent suppression of the topping up of water into the container. The suppression is effected when the measured concentration value of the dissolved substance falls below a first limit value or the value of the parameter falls below or exceeds a first limit value or when the change in the concentration value of the dissolved substance or of the value of the parameter exceeds a first limit value.

Abstract: The present specification describes systems and methods for detecting an occlusion in a tubing carrying a patient's blood through a manifold and into a dialyzer in a dialysis system. A controller measures pressures value of the blood at a predetermined point after exiting the manifold and before entering the dialyzer, calculates a historical running average, calculates a weighted sum of the most recent pressure values, and determines whether to trigger an occlusion alarm based on a function of the historical running average and the weighted sum of the most recent pressure values.

Abstract: In a sludge thickener water/wastewater treatment system, sludge solids are recirculated with a mixer positioned in the influent column or offset from the center column and within the stilling well, in order to produce essentially constant sludge solids concentration in the sludge withdrawn from the thickener. This solves the problem of thickeners producing inconsistent underflow solids concentration and often exhibiting problems with binding of rake arms due to sometimes very high sludge concentrations. Also, dewatering steps that follow thickening typically require a relatively constant solids concentration for efficient operation.

Abstract: A filter media in which larger corrugations are impressed or embossed onto media that has been previously corrugated with standard corrugations. This construction greatly increases the beam strength of a resulting pleat that allows the channels to remain open during processing into the pleated media, and prevents buckling of the media duping gathering on current pleating equipment. In addition, once the media is pleated, the larger corrugations or embossments, combined with the standard corrugations, create large channels for fluid flow from pleat tip to the base of the pleat.
