A water treatment apparatus using a lamella structure according to an embodiment of the present invention includes a first treatment tank which includes a plurality of inclined plates and is configured to pass water subject to treatment between the inclined plates adjacent to each other and a second treatment tank which is installed at a rear end of the first treatment tank to accommodate the water subject to treatment and into which bubbles are supplied, wherein the plurality of inclined plates include positive electrode plates and negative electrode plates that are alternately arranged, and the water subject to treatment passes between the positive electrode plate and the negative electrode plate.

Disclosed is a reverse flow multi-stage sedimentation rake-free thickening device relating to the field of slime water treatment. The device includes a feed assembly, a guide assembly, and a clean coal collection assembly. The guide assembly also includes a central tank body and coal slurry flows from the upper part of the central tank body to the inner side wall of the central tank body through the feed assembly and the medicament, and then flows to the middle of the central tank body through the guide assembly. After the reaction, the bubbles carry the fine coal slime and move up to the clean coal collection assembly. The clean coal collection assembly is located above the outlet of the guide assembly, and the clean coal collection assembly is sequentially provided with a central collection area, a defoaming area, and a diversion settlement area from the middle to the outside.

A system for recovery of animal byproducts and providing water reuse from an animal processing plant waste stream. In one embodiment of the invention there is an equalization tank forming part of an animal processing plant that is mechanically filtered to recover animal byproducts from a water mixture in the equalization tank. In another aspect of the invention there is a skimmer tank that contains a skimmer mixture with water and animal byproducts. The system mechanically separates the animal byproducts from the skimmer mixture in a manner that is suitable for human consumption. The system also allows the separated water to be reused in the animal processing plant.

A connection collar for a water treatment skimmer apparatus includes a body comprising a first material and defining a first circular hole and a bushing comprising a second material disposed within the first circular hole, the bushing defining a second circular hole. The first material is different than the second material and the first circular hole circumscribes and is concentric with the second circular hole, according to various embodiments. The water treatment skimmer apparatus may include a support bar, the connection collar rotatably coupled to the support bar, and a skimmer blade coupled to the connection collar.

A system for effectively removing biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia, total nitrogen (TN), and total phosphorus (TP) from wastewater has integrated multiple physiochemical and biological treatment processes into one unit. This system includes a primary DAF unit, anoxic bio-media treatment zone, and a secondary DAF unit. The bio-media treatment zones may be used to remove BOD and TN and may be divided into a number of functional zones. Each functional zone can develop and accumulate optimized bacteria species and microorganisms based on incoming wastewater BOD and nutrient levels.

A passive filter cell having a basin with a floor and two or more vertical or upright sidewalls forming chute or container having first or left sidewall, second or right sidewall, and third or back sidewall, and fourth or front downwardly curved sidewall, an inlet positioned proximate a top of the fourth or front sidewall and an outlet positioned proximate the top of the third or back sidewall, wherein the floor is configured angled from the fourth or front sidewall to the third or back sidewall, discharge pipe positioned proximate junction between the floor and the third or back sidewall, and lip configured to extend from the top of the third or back sidewall into an interior of the basin.
