The invention relates to an apparatus (7) for turning and/or mixing a flat bed compost. The apparatus (7) is provided with substantially vertical mixer elements (1, 2) which, during the operation of the apparatus, are adapted to travel within a composting mass and to mix the mass. The apparatus is adapted to travel freely on top of the composting mass without external support and/or guide structures. The apparatus can be towable by a vehicle, e.g. a tractor, or self-propelled.

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.

The system is for regulating the climate of the greenhouse. The warm greenhouse air is cooled by cooling water. The system has a spray condenser that includes a conduit for leading the cooling water to the condenser. The condenser has a blower to transfer warm air to be cooled to the condenser. The warm air from the greenhouse is used to warm the water sprayed from the spray condenser. The cooling water may be delivered from an evaporator that has water that is cooled by outside air blown into the evaporator.

The invention relates to a two-stage composter drum, comprising an inner, rotatably mounted drum (1) and an outer drum (2) having a housing which is thermally insulated and stationary. The compostable mass is introduced into the composter by way of an opening (3) included in one end of the inner drum and the pre-composted mass discharges through openings (6) in the other end of the inner drum (1) into an annular space (7) provided between the drums (1, 2) and fitted with carrier elements (8) for feeding the mass backwards while the final composting is in progress.

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.
