Where should Wastewater generated from Compressor or Boiler Blowdown be reported under, Is it under Domestic wastewater or Industrial Wastewater?
Our facility wastewater is connected to Municipality Wastewater Treatment offsite. We have no control over operations and do not treat water onsite. Are we still expected to have an emergency plan in case there's a problem with the wastewater treatment?
Regarding the definition of reuse process wastewater in H2H, does it refer only to closed-loop systems with water as working fluid?
To whom should the facility provide wastewater sludge training?
Does the septic tank produce sludge, and is it required for septic tank service providers to have a transportation permit for it?
Does the septic tank produce sludge, and is it required for septic tank service providers to have a transportation permit for it?
We use the coffee brewer to boil water and discharge it after manufacturing and outgoing QA testing process. Is the discharged water considered industrial wastewater and needs to be processed through the Wastewater Treatment Plant before discharging it?
If sludge is NOT dangerous, the facility has the analysis to prove it, and sludge is not manipulated or disposed of on-site, should employee training be focused on management procedures or other topics instead?
The ZDHC Supplier to Zero program has 3 levels. As Level 3 is still not enabled by ZDHC, is it enough for a facility to complete Supplier to Zero Level 1 to get full points?
If a factory has wastewater treatment plan (ETP) to recycle industrial wastewater coming from the washing section, for reuse in the washing section, but didn't run the washing section in 2023, what data should we fill in the wastewater section in FEM2023?
In the question, Does your facility currently have any records in the Institute of Public & Environmental Affairs (IPE) database? (Applicable only If, “Country or Region” = China), how should we respond as a facility not located in China?
How is dry sludge calculated and reported?
Both industrial and domestic sludge are stored together and treated as hazardous waste. Do we need to enter the data and report on each separately?
Do we need to do ZDHC testing on our wastewater if we have domestic wastewater only?
For facilities that only treat wastewater AND DON'T HAVE any wastewater recycling activities, does it mean that they don't have "Incoming water pre-treatment"?
Does incoming water pre-treatment only apply to facilities that extract water (surface water/groundwater) and/or recycle wastewater, then use it within the facility?
What if wastewater sludge is semi-solid, how is moisture content tested and the unit is m3 not in MT?
ZDHC testing of wastewater discharge (effuent), includes Metals only, how about SAC? Which parameters are to be tested?
Is zero liquid discharge required for subsequent levels in the wastewater section?
If our industrial wastewater is collected and treated by a third party, who then completes the treatment and reuses it for their cooling system, does this qualify our factory as reusing wastewater?
Our facility ETP sludge is being disposed of as hazardous waste in accordance with local law. Does sludge still need to be tested by facility or not required?
Does the BoD5 test need to be conducted for ETP and STP outlet water or only for STP?
For toilet effluent that goes through septic tanks and is then sent to offsite etp for treatment, would it be considered as offsite treatment only or onsite & offsite treatment?
Q14. Does your facility provide training to all employees whose job involves handling wastewater sludge (such as maintenance and janitorial staff)? Is this question applicable to domestic or industrial sludge?
If the factory has a wet process, and they’re using ZDHC guidelines to test and are compliant to ZDHC, but the guideline is only used as internal reference and test report is not submitted on ZDHC gateway, will the factory achieve full points for Q21-Q23?
Is 2nd-party or 3rd-party BOD 5 testing OK for facilities if there is no In-house lab for such? Or is an in-house lab mandatory?
If the factory doesn’t have a wet process (ex: the factory only has domestic wastewater), and only reports according to legal requirements, will the questions of level 2 be opened or not?
For Wastewater tests, can facilities registered in ZDHC Gateway use this data as input into the FEM module directly?
In case of water discharge measurement, is it mandatory to measure using instruments or can measurement be done by calculation estimates?
What is the frequency of this test?
