MATERIAL - Task 1.4.2
Use of by-products of local industries for wastewater treatment in Rosignano and/or Cecina
Partners:
OBJECTIVES:
Recovery of:
- Bentonite, mineral by-products as alternative
coagulants/adsorbents;
- Residual hydrogen peroxide and peracetic acid
for disinfection;
- Chemical sludge from coagulation/flocculation
for Alu Circles initiative
Content of study:
- Tests on by-products
- Tests on alternative GAC
- Economic value of the recovered product
- Impacts on the operation of the WWRTP
