  "text": "In order to minimise water consumption, BAT is to use one or both of the techniques given below.\nTechnique\nDescription\nApplicability\na\nThe optimisation of water use in all wet process steps, including the use of batch washing instead of running water washes\nOptimisation of water use is achieved by determining the optimum quantity required for each process step and introducing the correct quantity using measuring equipment. Batch washing involves washing of hides and skins during processing by introducing the required quantity of clean water into the processing vessel and using the action of the vessel to achieve the required agitation, as opposed to running water washes which use the inflow and outflow of large quantities of water.\nApplies to all plants carrying out wet processing.\nb\nThe use of short floats\nShort floats are reduced amounts of process water in proportion to the amount of hides or skins being processed as compared to traditional practices. There is a lower limit to this reduction because the water also functions as a lubricant and coolant for the hides or skins during processing. The rotation of process vessels containing a limited amount of water requires more robust geared drives because the mass being rotated is uneven.\nThis technique cannot be applied in the dyeing process step and for the processing of calfskins.\nApplicability is also limited to:\nnew processing vessels,\nexisting processing vessels that allow the use of, or can be modified to use, short floats.\nThe review of options for the reuse of process/washing water is part of an Environmental Management System (see BAT 1) and of the principles of good housekeeping (see BAT 2).",
