Foam is a naturally occurring phenomenon in aeration basins in which biological wastewater treatment occurs. Samplers should include photographs of the foam they witnessed in the final lab report, along with the time and date of taking such photos. The foam colour should be similar to the liquid in the aeration basin, should dissipate quickly and should be contained within the aeration basin. For direct discharge facilities, samplers should check for persistent foam on the surface of receiving waters at the point of discharge and the presence or absence of foam should be noted. This should be checked at the same location used for sampling the temperature difference. This test is to be done on-site by the sampler. In case the receiving body is not accessible or risky to access for the sampler, a visual estimation of the foam in the aeration basin should be done. If the foam is higher than 45 centimetres in height (by visual estimation) then it could result in permanent foam being discharged onto the surface of receiving waters and should be reported as ‘fail’ for the foam parameter. |

There may be situations where the sampler is not able to measure the temperature of the receiving body. These situations may include: • The receiving body may be several kilometres away from the point of discharge and the facility is discharging the effluent into the receiving body through a pipeline. • Accessing the location of the receiving body to measure its temperature can be risky in terms of injury to the sampler or damage to equipment. • The effluent is discharged directly into the ground. In all such cases where access to the receiving body is not possible or unsafe, ONLY then the laboratory should report Temperature absolute in the EDR. |

Take the temperature of the discharged wastewater and the receiving body of water upstream. The temperature of the receiving body is subtracted from the temperature of the discharged wastewater to give the delta temperature difference, which can be a positive or a negative value. The discharge limits only refer to a positive value, which produces an overall increase in the temperature of the receiving body of water. This parameter is measured on-site by the sampler and is applicable only for direct discharge. There may be situations where the sampler is not able to measure the temperature of the receiving body. These situations may include: • The receiving body may be several kilometres away from the point of discharge and the facility is discharging the effluent into the receiving body through a pipeline. • Accessing the location of the receiving body to measure its temperature can be risky in terms of injury to the sampler or damage to equipment. • The effluent is discharged directly into the ground. In all such cases where access to the receiving body is not possible or unsafe, the laboratory should report this parameter as “Not Applicable”. |

Salt that comes from incoming water or is deliberately used in wet processing or that is formed due to neutralisation reactions, and that is not remediated by treatment in an efficient ETP, can negatively affect the aquatic environment when discharged. In all situations, TDS must comply with the local regulatory standards. ZDHC encourages initiatives to reduce water consumption but recognises that world class, low levels of water use can result in lower levels of dilution and thus higher TDS values. In the present version of the ZDHC Wastewater and Sludge Guidelines, this parameter is reported as “Sample & report” so that data is captured. However, in future, ZDHC is planning to introduce ‘load based’ limits for TDS that takes into account the volume and concentration of discharged effluent linked to and water consumption and production volumes for textile and leather facilities. |

| For direct discharge type of facilities the following parameters must be measured on-site every hour by the sampler during the composite sampling: pH, temperature difference or temperature absolute, persistent foam, wastewater flowrate, total chlorine and dissolved oxygen. Refer to the ZDHC Wastewater and Sludge Laboratory Sampling and Analysis Plan for more information. For flow rate, the applicability of testing is based on < or > 15m3/day. | ||||||
