A liquid cleaning system rests on a surface having a non-porous material covering and a drain. A plate layer has two or more layers, each have runners arranged in a grid. The grid of each successive layer is offset at an angle with respect to the grid of a previous layer. An upper layer covers the plate layer and has a plurality of holes for the passage of fluids into the liquid cleaning system. As fluids enter the liquid cleaning system through the holes, the liquid traverses the grid layers of the plate layer, flowing towards the drain. Contaminants within the liquid collect within the grid of the layers of the plate layer.

Polymer compositions containing polyethylene particles having a multi-modal molecular weight distribution are disclosed. The polymer compositions are well suited to producing porous substrates through a sintering process. Formulations made according to the present disclosure can produce porous substrates having improved flexibility demonstrated by an increased flexural strength while still retaining excellent pressure drop characteristics.

A device and system for purifying a fluid is provided. The device includes a tank having a hollow interior and a lock feature. A cover is sealingly coupled to the tank. A release assembly is pivotally coupled to the cover and engaged with the lock feature, the release assembly having a relief valve fluidly coupled to the hollow interior and a lock member, the release assembly being rotatable between a first position and a second position, wherein the relief valve is in a closed position and the lock member is engaged with the lock feature in the first position, and wherein the relief valve is open and the lock member rotates away from and is disengaged from the lock feature in the second position.

A mobile rustproofing washing system includes a receptacle, a control module, a water supply module, a filtration module and a washing module. The receptacle is removably disposed on a mobile carrier. The control module is disposed in the receptacle. The water supply module is disposed in the receptacle and includes a front water tank and a rear water tank. The filtration module is connected to the front water tank and the rear water tank. The filtration module receives and filters water from the front water tank. The filtered water is stored in the rear water tank. The washing module connects with the rear water tank and receives water therefrom, so as to carry out a washing process. Therefore, the mobile rustproofing washing system is quick to mount/demount and easy to use, thereby having high mobility.

The present disclosure relates to recycling automotive phosphate rinse water. An apparatus and method is disclosed for treating process water containing phosphate. The apparatus may include a process water line. The process water line may be in fluid communication with a sample process water line. The sample process water line may be in fluid communication with a dilution line. The sample process water line, the dilution line, and a phosphate analyzer may be in fluid communication with a diluted process water line. The apparatus may also include a chemical additive feed line in fluid communication with the process water line downstream from the sample process water line.

There is provided a novel composition for enhancing the quality of oily wastewater, the composition comprising oil shale ash particles physically bonded to a polymer matrix. There is also provided a method for preparing the composition, and a method for treating oily wastewater using the composition thereof.

A liquid cleaning system rests on a surface having a non-porous material covering and a drain. A lower plate layer and an upper plate layer each have runners arranged in a grid. The lower plate layer rests upon the surface and the upper plate layer rests upon the lower plate layer offset at an angle with respect to the grid of the lower plate layer. An upper layer covers the upper plate layer and has a plurality of holes for the passage of fluids into the liquid cleaning system. As liquid enters the liquid cleaning system through the holes, the liquid traverses the grid of the lower plate layer and the grid of the upper plate layer flowing towards the drain, and contaminants within the liquid collect within the grid of the lower plate layer and the grid of the upper plate layer.

Systems, apparatuses and methods related to treating and/or recycling a wastewater for reuse are described.

A method for cleaning vehicles by means of which the formation of marks caused by drying is prevented. The method comprises a rinsing step using water. In the method, the anions forming poorly soluble salts with alkaline earth metals dissolved in water are removed from the water, while cations causing the water hardness are retained. Furthermore, a vehicle washing system includes: at least one application device for applying rinsing fluid to a vehicle to be cleaned; and an ion-exchange device for removing anions from the rinsing fluid prior to the application to the vehicle.

A Biorefinery System (BIOSYS) that effectively treats all human activity-derived waste (black water, grey water, and food waste streams) using biological systems and that produces as process by-products: recovered potable water, liberated free oxygen, edible protein cake (with and without lipids), soil amendments, and machinery lube oils. Additionally, the system captures and chemically binds carbon dioxide into microbial cells and associated by-products, thus producing recovered usable returned cabin air.
