An aqueous composition for treatment of water comprising: (a) an N,N-dimethyl-2-hydroxypropylammonium chloride polymer; (b) lanthanum chloride; and (c) a dimethylamine epichlorohydrin ethylenediamine polymer; and a method of treating water using the composition.
An apparatus for treating water stored in a reservoir to remove contaminants has a feed line (25) for receiving water to be treated and a by-pass valve (26) that controls the flow of water through the feed line (25) by allowing a regulated flow of the water through a flow line (28). A venturi valve (30) responds to the rate of flow of water through the flow line (28) by creating a vacuum in a supply line (36) from an ozone generator (15), the extent of the vacuum created being dependent on the rate of flow, to add ozone at a controlled rate to the water to be treated. A sensor probe (27) measures the oxidation reduction potential of the water, to supply hydrogen peroxide to the water at a controlled rate dependent on the oxidation reduction potential level. The ozone and the hydrogen peroxide are mixed with the water in a multicyclone unit 14 to allow a peroxone reaction to occur that treats the water, and the treated water is returned to the reservoir.
A chemical analyzer analyzes a sample for a target chemical. The sample and reagent are added to a measurement cell until a detectable change is observed. A reference compound, which does not take part in the reaction between the target chemical and reagent, is added to the reagent. By measuring the concentration of the reference compound, the amount of reagent used may be determined. In one embodiment, a mechanism introduces the sample, adds reagent, mixes, cleans, and flushes the measurement cell, which incorporates a longitudinal chamber having inlets for the sample and reagent and an outlet for measured sample/reagent mixtures. A detector located in or adjacent to the chamber between the inlets and outlet and a piston movable in the chamber carries seals such that movement of a piston sequentially opens the inlets and expels the fluid. The analyzer also includes a device that delivers reagent to a measurement cell.
