The present inventors have surprisingly discovered that phytic acid tenaciously precipitates with soluble metals in food or fuel ethanol-processing fluid, producing insoluble organometallic salt deposit or scale on the processing equipment that must be removed in order to facilitate further ethanol processing. The present invention relates to converting phytic acid salts or phytates to inorganic phosphates to improve metal solubility and reduce deposition within processing equipment.

An oral irrigator has a removable reservoir defining a reservoir cavity, a base unit housing a motor and a pump, and a handle for directing fluid flow from the pump removably connected to the base unit and fluidly coupled to the pump by a hose. The handle has a housing defining a slot formed in an outer wall of the housing. The slot is bounded by two opposing walls spaced apart from each other and a transverse wall at a terminal interior end of the opposing walls. The outer wall of the housing is open to the slot at lateral sides of the two opposing walls and at a base end of the opposing walls opposite the transverse wall.

An oral irrigator handle has a handle housing with a swivel assembly for connection to a hose further connected to a fluid source. A tip for directing a focused stream of fluid is releasably connected to a first end of the handle. The swivel assembly is received within the housing and fluidly coupled to tip. The hose is connected to the swivel assembly and fluidly coupled to the tip via the swivel assembly. The swivel assembly prevents translation of rotational movement of the handle or the hose to the other.

Systems for water treatment include a preprocessing stage, an ultraviolet treatment stage, and a filtering stage. The preprocessing stage includes first and second chambers including first and second filter media. The first and second chambers include perforated plates. The first chamber and second chamber are vertically arranged in a filter tower. The ultraviolet treatment stage receives water in a plurality of reactor tanks. Each reactor tank of the plurality includes an inlet, an outlet, crystal sleeve disposed centrally to the interior of the reactor tank, and a UVC light source contained within the crystal sleeve. A controller operates the ultraviolet treatment stage to sequentially fill each reactor tank and sequentially drain each reactor tank and operates a respective UVC light source to emit UVC wavelength radiation within a respective reactor tank while water is in the respective reactor tank.

Wood pulping process including pulping wood to produce a pulping effluent or liquor. Pre-concentrating the liquor in a pre-concentration unit produces concentrated liquor, a contaminated condensate and a non-contaminated condensate. Directing the concentrated liquor to a multi-effect train of forced circulation solids concentrators that further concentrating the concentrated liquor to form a highly concentrated liquor. Directing the contaminated condensate produced by the pre-concentration unit to a steam stripper and stripping gases therefrom and in the process producing a contaminated vapor stream. Utilizing the contaminated vapor stream and its thermal energy to power the forced circulation solids concentrators of the multi-effect train.


There are provided a method for purifying a hydrogen gas and an apparatus for purifying a hydrogen gas, which are capable of purifying a hydrogen gas with a high recovery ratio by removing an impurity constituent from a hydrogen gas extracted by an organic chemical hydride method etc. In the method for purifying a hydrogen gas, a raw material hydrogen gas containing an impurity constituent is purified using two adsorption towers (10A) and (10B) each filled with an adsorbent. The method comprises: repeatedly carrying out an adsorption cycle including at least an adsorption step of separating the impurity constituent from the raw material hydrogen gas by adsorbing the impurity constituent to the adsorbent in the adsorption towers (10A) and (10B), and a heating and regeneration step of desorbing the impurity constituent from the adsorbent by supplying a heated purge gas to the adsorption tower after the adsorption step, in each of the adsorption towers (10A) and (10B); and while carrying out the adsorption step in one adsorption tower, carrying out a step other than the adsorption step in the other adsorption tower. The heating and regeneration step includes circulating the purge gas while heating the purge gas.
