Wastewater Treatment Systems for Tanneries


Hydroflux Industrial are experts in the design and construction of wastewater treatment plants for the Tanneries

Hydroflux Industrial has extensive experience in wastewater treatment for tanneries including all aspects of system design and construction of primary and biological processes and complete sludge management systems.

At Hydroflux Industrial, our engineers are fully conversant with the internal production processes of tanneries and as such, we understand the sources of the wastewater, along with the fluctuations commonly experienced with flow and load. We know the effects that different methods of hide preservation have on the wastewater characteristics and how various chemicals used in the tanning process vastly change the nature of the wastewater stream. Furthermore, we know that accidents do happen and armed with this knowledge, our robust plants are always designed to consistently perform under all conditions.



Typical Processes

HydrofluxIndustrial_Supplementary_1The characteristics of tannery wastewater vary considerably depending on the nature of tanning process. Factors such as, the amount of water used, the methods of hide preservation, and the chemical methods used for tanning the hides greatly affect the wastewater quality.

Treatment of wastewater from tanneries almost always requires screening followed by a chemical physical process to remove solids, grease and some other potentially toxic compounds. If the wastewater is being discharged to the sewer system, then quite often this primary treatment stage will be adequate. If wastewater is being discharged to the environment then a very robust biological system such as MBR, MBBR, multiple SBR units or a hybrid combination will be required due to the resistant and toxic compounds present and the wastewater’s relatively low biodegradability
