  "text": "In order to reduce the pollutant load in the waste water before effluent treatment arising from the tanyard process steps, BAT is to use an appropriate combination of the techniques given below.\nTechnique\nDescription\nApplicability\na\nThe use of short floats\nShort floats are reduced amounts of process water. When less water is present, the quantity of process chemicals which is discarded unreacted is reduced.\nThis technique cannot be applied 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.\nb\nMaximising the uptake of chromium tanning agents\nOptimisation of the operating parameters (e.g. pH, float, temperature, time, and drum speed) and the use of chemicals to increase the proportion of the chromium-tanning agent taken up by the hides or skins.\nGenerally applicable.\nc\nOptimised vegetable-tanning methods\nUse of drum tanning for part of the process.\nUse of pretanning agents to aid penetration of vegetable tannins.\nCannot be applied in the production of vegetable-tanned sole leather.",
