A low profile ice maker/dispenser and water dispenser having a high ice making capacity, for ice nugget manufacture is provided, wherein ice nuggets are metered out of a storage bin via a nugget dispenser outlet, and whereby water is dispensed via a water dispenser outlet. A refrigeration cycle is used, wherein an auger compresses ice on a wall of an evaporator and delivers the ice to the ice bin, breaking it into nuggets along the way. An outer wall of the evaporator is comprised of part of the water reservoir. A baffle in the ice bin facilitates metering of the amount of ice discharged. The system comprises a closed system that enables efficient cleaning of the system.

A method of removing complexed zinc-cyanide from wastewater involving a multiple stage process including, in a first step, control of ferrous ions to a critical minimum concentration of 250 to 400 ppm, together with pH control in the first and also a second step, together with recycling of a portion of sludge precipitated in the process. Improved sludge stability is achieved by aeration to oxidize precipitated ferrous hydroxide to ferric hydroxide, immediately before settling the sludge in a thickener.
