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?
-
Where exactly is the BOD5 test required to be performed?
-
What is the BOD5 test?
-
Is there a level amount of wastewater generated to measure the BOD of waste water input etc?
-
Wastewater input-outputs are regularly tested as per Local Government standard and not ZDHC Methods. Will it be acceptable as per Higg FEM 4.0?
-
If a facility has both domestic and industrial wastewater. Do they need to have a wastewater reduction target for both types of wastewater?
-
If a facility treats wastewater from both domestic and production processes in one wastewater treatment plant should the facility still be required to separately track the sludge between domestic and production processes?
-
Regarding % solids of wastewater sludge; this % value refers to solids of wastewater sludge at which stage? Before or after dewatering?
-
We have industrial wastewater, but we don't see any ZDHC questions appearing. Why might this be?
-
As a vertical supplier, we have industrial wastewater discharged to a single ETP. Almost all the wastewater is from the T2, with much less from the T1. Can we consider the ETP as part of or belonging to the T2?
-
Wastewater after treatment used for toilet flushing, should it be categorized as recycled water or reused water?
-
The wastewater in our factory first flows into the septic tank and then into the third-party sewage treatment plant. Which treatment method should we select?
-
Is ink sludge from the industrial preliminary treatment system classified as 'Pre-water treatment sludge' or not?
-
What is the definition of industrial wastewater?
-
For the question concerning % solids of wastewater sludge generated, we generally measure the sludge according to weight and not according to the % wastewater generated. Can the unit of measure be changed to kg?
-
Should freshwater pre-treatment be distinguished from wastewater pre-treatment in considering whether a facility has onsite water treatment?
