This invention relates to an apparatus attachable to a small-scale purification unit for precipitating phosphorus from waste water, said apparatus comprising a pumping vessel (1), a discharge pump (2) for unloading the pumping vessel, a chemical tank (6), a chemical metering pump (5) for dispensing a chemical from the chemical tank (6) into waste water to be discharged from the pumping vessel (1), whereby a separation of the resulting chemical precipitate from water draining out of the purification unit is arranged to be accomplished in a settling tank (12) of the small-scale purification unit. In this invention, the metering pump (5) is arranged to supply a chemical coagulant into an effluent flow discharged by the discharge pump (2) over an entire or almost entire operating cycle of the discharge pump (2).

The invention relates to a small-scale treatment unit for waste water, comprising one or more series of solid-bottom trays (1, 9) arranged relative to each other descendingly in the flowing direction of the water to be treated and containing a replaceable or flushable filling material, and that the trays are set at an inclination of 0-10% and that the trays (1, 9) have at least one end wall or skirt thereof provided with openings (4, 13) for passing water in each series of trays always from a higher tray (1, 9) to the next tray therebelow, the waste water to be treated being forced to flow through each tray and a layer of filling material contained therein in a substantially horizontal flow to at least one end wall or skirt of the tray (1, 9), the openings (4, 13) present therein providing a passage for the water to flow into the next tray in the series, such that the waste water to be treated is forced to flow through all trays in each series of trays in the treatment unit and to discharge by way of the openings (4, 13) provided at the end wall or skirt of the lowermost tray in a series of trays.

An object of the invention is to provide a novel, economic method for the production of natural nutrient sticks, especially natural manure based fertilizer sticks, in a manner that the natural nutrient in question can be used in premises with people around without causing odor problems. According to the invention, manure is sorted out, additives are possibly added therein, the mixture is dried and comminuted by per se known methods and is shaped into sticks by extruding the mixture, while heating it, through a matrix, followed by cutting the obtained fertilizer sticks to a desired maximum length, e.g. a few centimeters, cooled, possibly sorted out and packed.

The invention relates to a culture medium package suitable for growing plants, especially in greenhouse production. The culture medium package contains a basically fertilized or non-fertilized culture medium portion (1) and a fertilizer portion (2) in a direct contact therewith, the fertilizer contained therein being blended by no more than to a slight degree with the culture medium. The fertilizer portion (2) is in such a condition that the plant roots are able to penetrate therein. Thus, no supplemental fertilization is required during the growing season.

The invention relates to a composting device (1) and a method for composting. The composting device (1) comprises a compost container (3) provided with a feed opening (10) through which waste to be composted is added into the compost container (3). The compost container (3) comprises a belt loop (6) circulating inside it for the purpose of turning, mixing and/or moving the waste to be composted.

The invention relates to a composter (1), comprising on top of each other a feeding zone (2), a composting zone (3) and a discharge zone (4). The feeding zone (2) is provided with means for feeding compostable mass into the composter. The discharge zone (4) is provided with means (17) for removing compost mass with a desired degree of ripeness from the composter. The composter (1) includes first separation means between the composting zone (3) and the discharge zone (4). Said first separation means comprise a first disc-shaped member (6) which is provided with at least one through slot (16), said slot having a cutting edge (160. The composter is provided with elements by means of which the first disc-shaped member is drivable for rotating the same around its center axis, whereby said first cutting edge (160 enables some mass to be cut off of the presently treated mass present above the first disc-shaped member (6), said cut-off mass being conveyable through said slot (16) into the discharge zone (4) underlying the first disc-shaped member (6). The invention relates also to a method for composting in a composter.
