An improved composition for and method of priming a concrete pump line is provided. The flowable composition comprises a solid particulate mixture and water, the particulate mixture being comprised of solvatable polymeric material preferably selected from a group consisting of polyacrylamide, polyacrylate and mixtures thereof; an organic complexing agent preferably of urea; and a buffering agent preferably of citric acid. The invention provides a flowable composition exhibiting improved coating and lubrication to the inner walls of a concrete line as it passes therethrough. The flowable composition mixes quickly with water to form a clear solution, hydrates quickly upon being mixed with water, and provides a composition for use in priming concrete pump lines that does not utilize cement or priming grout slurry.

Abstract:
In a first embodiment of the method and apparatus, the oxidant is loaded upon a support bed and is continuously regenerated by an ozone generator located upstream from the support bed. The ozone generator has a capacity less than the peak load requirement for the oxidant but fully regenerates the oxidant during low load periods. An ozone detector is located downstream from the support bed and includes a control circuit for selectively deactivating the ozone generator when the ozone downstream from the support bed exceeds a predetermined level. The support bed is composed of inert or adsorbing granular material. In a second embodiment, an aqueous solution containing a water soluble oxidant is applied to the support bed and is rinsed out following a purification cycle. The rinsed oxidant is replaced by fresh oxidant from a reservoir and the rinsed, spent oxidant is regenerated in an electrolytic or chemical regenerator and returned to the oxidant reservoir. Parallel, alternatively operated, conduit sections including support beds therein may be provided so that one conduit section is operative to purify air flow while the other conduit section is being regenerated.
