A launder cover system for reducing or eliminating sunlight exposure so as to prevent algae growth in a tank such as a clarifier tank. The launder cover system generally includes a plurality of support members and a plurality of launder covers which are each independently pivotably connected to a tank wall of a tank, such as by using a mount. The support members are each pivotably connected to the tank wall by a pivot connector and the launder covers are each pivotably connected to the tank wall by a hinge connector. Each support member is positioned between a pair of launder covers, and each launder cover is positioned between a pair of support members. The support members function to support the launder covers in a raised or lowered position. A launder support may be connected to the channel wall to support the launder covers in their lowered positions.

A wastewater dissolved-air floatation apparatus combined with a precipitation tank having sloped plates is proposed. The apparatus can reduce a transfer load according to the discharge of sludge, when the sludge is discharged through a discharge screw which is a discharge means, so as to enable sludge discharge efficiency to be maximized, has a cleaning means so as to enable components provided therein to be easily cleaned, maintained and managed through cleaning when the inside thereof is required to be cleaned, can control the discharge level of wastewater, which has been treated while sludge precipitation and suspended particle floatation are stably performed thereon inside a separation tank to which microbubbles are supplied, selectively blocks the supply of the microbubbles into the separation tank so as to use the separation tank as a precipitation tank.

An adjustable separation system for separating particles suspended in a liquid and method of using same are disclosed. Embodiments are directed to an adjustable separation system that includes an adjustable particle separation channel including: a plurality of plate electrodes; and an adjustable inclination system configured to adjust inclination of the plate electrodes through a range of angles, or an adjustable spacing system configured to adjust spacing between adjacent plate electrodes. The adjustable separation system allows the particle-laden liquid to traverse the plate electrodes within the separation channel, thereby separating the particles from the liquid while using the Boycott effect. These and other embodiments achieve separation of particles suspended in a liquid via an adjustable separation system and, optionally, without the need for manual/technician adjustments, which can result in improved efficiency, quicker separation/operating time, and reduced power consumption and cost.

A tensile structure density current baffle for use in a clarifier tank having a side wall includes a tensioning cable and a central baffle portion formed from a membrane fabric. The central baffle portion has an upper baffle portion with an upper end, a lower baffle portion with a lower end, and a junction between the upper baffle portion and the lower baffle portion. The tensioning cable engages the central baffle portion at the junction. The upper end of the central baffle portion being fastenable to the side wall above the junction and the lower end of the central baffle portion being fastenable to the side wall below the junction. When the upper end and lower end are fastened to the side wall and the tensioning cable is tensioned, the tensioning cable and membrane fabric comprise a self-supporting tensile structure that extends toward the center of the clarifier tank.
