Waste in a black or gray water holding tank is treated by an oxygen activated biocide by the addition of tetra acetyl ethylene diamine (TAED) and a peroxygen compound. Hydrogen peroxide and/or peracetic acid are released over a period of time and thus maintained in the wastewater solution. Peracetic acid under controlled release conditions dissipates prior to the wastewater being deposited in a wastewater treatment plant.

An electrically driven type low-pressure fuel pump whose flow rate can be set draws fuel from a fuel tank and discharges it at a prescribed pressure commonly to a low-pressure fuel supply system including intake manifold injectors and a low-pressure delivery pipe and to a high-pressure fuel supply system including in-cylinder injectors, a high-pressure delivery pipe and a high-pressure fuel pump. The discharge flow rate of the low-pressure fuel pump is set based on required supply quantities to ...

Effervescent compositions are disclosed. The effervescent composition may include at least one compound capable of effervescence in the presence of a liquid, such as water. The effervescent composition may also include a non-hygroscopic solvent. The presence of the non-hygroscopic solvent may assist the effervescent composition in substantially avoiding effervescence until the composition contacts a liquid. Optionally, the ratio of the at least one compound capable of effervescence to the non-hy...

A tablet of compacted particulate cleaning composition has about 0.5-10% by wt. of a composite disintegrant blend of, by weight, (a) about 20-80% of a water soluble salt, (b) about 80-20% of crosslinked polyvinylpyrrolidone (PVPP), the tablet having a disintegration rate of at least 40 g/min.

Coated solid bodies comprising a core of an active composition and having a water-soluble or dispersible micro-porous or net-coating. The coating improves the mechanical characteristics of the solid body and allows for good dissolution. The coated solid bodies preferably take the form of detergent tablets.

A process for making substantially water- and dust-free anionic surfactant granules of high bulk density involving: (a) providing a starting material containing a water-containing paste of a monoglyceride (ether) sulfate having a solids content of at least 20% by weight, based on the weight of the paste; (b) providing a horizontally mounted thin-layer evaporator with rotating internals; (c) providing a negative temperature gradient within the evaporator; (d) passing air into the evaporator in co...

The present invention relates to a perfumed detergent tablet, the tablet comprising a clay mineral compound, and the perfume comprising less than 0.6% of Schiff-base by weight of the perfume composition.

The invention relates to a method for producing aromatic shaped bodies, especially aromatic beads, with bulk densities greater than 700 g/l, whereby a solid and essentially water-free premix comprised of a) 65 to 95 wt. % carrier(s), b) 0 to 10 wt. % auxiliary agent(s), and c) 5 to 25 wt. % perfume is subjected to granulation or compacted agglomeration. In addition, the invention relates to the application of the inventive aromatic shaped bodies in order to scent washing and cleaning detergents,...

A machine dishwashing detergent tab pack comprising a tablet form detergent composition surrounded by a wrapper, the detergent composition in the form of at least two seperate tablet form portions or in a single tablet form divided into portions, wherein at least two of the separate portions contained in the wrapper differ in composition.

The invention relates to a detergent composition comprising a bleach-sensitive component and a hydrogen peroxide source, wherein the hydrogen peroxide source is present in a particulate component having an average particle size, by weight, of from 700 microns to 1100 microns, preferably from 750 microns to 1000 microns, whereby at least 80% by weight of the particulate component comprising the hydrogen peroxide source has a particle size of between 70% to 130% of the average particle size. The c...
