The invention relates to the formulation and application of water based predominantly pH neutral microemulsions and microemulsion forming surfactant systems essentially comprising a surfactant or surfactant˜end, lactates)—esters) of lactic acid—and water/brine and optionally solvent. Uniquely the formulations are acid and caustic free and also do not make use of alcohol, glycol and glycol ether components in the systems as co surfactant, co-solvent or mutual solvent. In particular the invention relates to the methods and the application of this microemulsion technology for use in industrial hard surface cleaning applications especially the inks and printing industries and the oil and gas industry. In addition the formulations can be used in the production of microemulsion based drilling muds (which may or may not be Oil Based Muds—OBMs) and they may be used to enhance the drill cuttings slurrification processes for re-injection purposes or for facilitated cuttings transport.

The invention relates to the field of industrial wastewater treatment processes and provides a method for deeply treating, desalting and recycling industrial wastewater with high salt content. The method comprises the following steps: 1) carrying out efficient coagulation treatment on the industrial wastewater with high salt content to obtain supernatant; 2) carrying out chemical precipitation on the supernatant obtained in the step 1) to remove high valence ions with valence higher than bivalence in the wastewater; 3) carrying out catalytic ozonation treatment on the supernatant subjected to chemical precipitation in the step 2); 4) carrying out multi-media filtration, precise filtration and membrane filtration treatment on the wastewater subjected to catalytic ozonation in the step 3) in sequence; and 5) carrying out electrodialysis reversal treatment on the effluent obtained after membrane filtration in the step 4). By adopting the method, organic matters, bacteria, colloids, suspended particles, Ca<2+>, Mg<2+> and high valence ions, other soluble inorganic salts and the like in the industrial wastewater with high salt content are removed by utilizing the coupling and synergistic effects of different unit technologies, thus achieving deep treatment, desalting and recycling of the industrial wastewater with high salt content.

A cooling system is provided for a non-rail off-road vehicle, such as an agricultural tractor having an engine with a horizontally oriented rotation axis and a hood covering the engine. The cooling system includes an engine cooling radiator positioned above the engine and between the engine and the hood and a fan unit with electric motor-driven fans blowing air upwardly through the radiator. The fan unit is positioned above the engine and between the engine and the radiator. An engine charge air cooler is also positioned above the engine and between the engine and the hood, and a charge air cooler fan unit has electric motor-driven fans which blow air upwardly through the cooler. The hood has openings in its upper surface through which passes air blown by the radiator fan unit and the charge air cooler fan unit. This cooling system blows heated cooling air vertically upwardly, thus preventing the heated cooling air from being drawn back into the intakes of the cooling system and preventing heated air from being blown onto the exterior of the tractor cab.
