  "text": "BAT 7. In order to reduce water consumption and the volume of waste water discharged, BAT is to use BAT 7a and one or a combination of the techniques b to k given below.\nTechnique\nDescription\nApplicability\nCommon techniques\n(a)\nWater recycling and/or reuse\nRecycling and/or reuse of water streams (preceded or not by water treatment), e.g. for cleaning, washing, cooling or for the process itself.\nMay not be applicable due to hygiene and food safety requirements.\n(b)\nOptimisation of water flow\nUse of control devices, e.g. photocells, flow valves, thermostatic valves, to automatically adjust the water flow.\n(c)\nOptimisation of water nozzles and hoses\nUse of correct number and position of nozzles; adjustment of water pressure.\n(d)\nSegregation of water streams\nWater streams that do not need treatment (e.g. uncontaminated cooling water or uncontaminated run-off water) are segregated from waste water that has to undergo treatment, thus enabling uncontaminated water recycling.\nThe segregation of uncontaminated rainwater may not be applicable in the case of existing waste water collection systems.\nTechniques related to cleaning operations\n(e)\nDry cleaning\nRemoval of as much residual material as possible from raw materials and equipment before they are cleaned with liquids, e.g. by using compressed air, vacuum systems or catchpots with a mesh cover.\nGenerally applicable.\n(f)\nPigging system for pipes\nUse of a system made of launchers, catchers, compressed air equipment, and a projectile (also referred to as a ‘pig’, e.g. made of plastic or ice slurry) to clean out pipes. In-line valves are in place to allow the pig to pass through the pipeline system and to separate the product and the rinsing water.\n(g)\nHigh-pressure cleaning\nSpraying of water onto the surface to be cleaned at pressures ranging from 15 bar to 150 bar.\nMay not be applicable due to health and safety requirements.\n(h)\nOptimisation of chemical dosing and water use in cleaning-in-place (CIP)\nOptimising the design of CIP and measuring turbidity, conductivity, temperature and/or pH to dose hot water and chemicals in optimised quantities.\nGenerally applicable.\n(i)\nLow-pressure foam and/or gel cleaning\nUse of low-pressure foam and/or gel to clean walls, floors and/or equipment surfaces.\n(j)\nOptimised design and construction of equipment and process areas\nThe equipment and process areas are designed and constructed in a way that facilitates cleaning. When optimising the design and construction, hygiene requirements are taken into account.\n(k)\nCleaning of equipment as soon as possible\nCleaning is applied as soon as possible after use of equipment to prevent wastes hardening.\nFurther sector-specific techniques to reduce water consumption are given in Section 6.1 of these BAT conclusions.",
