Enhancement of microfiltration performances of pozzolan
In other words, the membrane is able to remove 99.77% and 97.83% of turbidity respectively for aluminum chloride suspension and tannery wastewater. Additionally, it could be suggested that obtained membrane could be used for treatment of other wastewater and also it could be used as support to develop more selective membrane layers.
Conclusion. Salt tolerant bacterial mixed consortia showed appreciable biodegradation at all saline concentrations (2%, 4%, 6%, 8% and 10% w/v) with 80% COD reduction in particular at 8% salinity level the consortia could be used as suitable working cultures for tannery saline wastewater treatment.
Enhancement of Tannery Wastewater Treatment at Low
As one of the heavily polluted industrial wastewaters tannery wastewater, which is difficult to handle especially in winter at low temperature, has attracted intensive attention all over the world recently. This work investigated the application of coagulation-flocculation to improve the treatment of raw tannery wastewater at low temperature (10??C).
The wastewater from tannery industry, using single treatment technology has not been enough to remove the chromium (Cr 6+) or high organic content (COD).Electrocoagulation (EC) and Biological Fungal Treatment (BFT) which endure against toxic and/or highly organic content, are promising technologies to eliminate impurities of tannery wastewaters.

Influences of Extracellular Polymeric Substances
The moisture content of sewage sludge can only be reduced to around 70% when it is treated by mechanical dewatering methods – because of the extremely low dewaterability of sewage sludge, and the associated capital and operating costs usually account for as high as 25–50% of the total expenses of the whole wastewater treatment processes

Electroplating sludge is a hazardous waste produced in plating and metallurgical processes which is commonly disposed of in safety landfills. In this work, electroplating sludge containing 25.6% Fe and 5.5% Co (named S1) and another containing 36.8% Fe and 7.8% Cr (S2) were recycled for the preparation of erdite-bearing particles via a facile hydrothermal route with only the addition of Na2S
A biosensor with improved performance was developed through the immobilization of horseradish peroxidase (HRP) onto electropolymerized polyaniline (PANI) films doped with carbon nanotubes (CNTs). The effects of electropolymerization cycle and CNT concentration on the response of the biosensor toward H2O2 were investigated. It was found that the integration of CNTs into the biosensor system
PLOS ONE: Influences of Extracellular Polymeric Substances
Extracellular polymeric substances (EPS) play important roles in regulating the dewaterability of sludge. This study sought to elucidate the influence of EPS on the dewaterability of sludge during bioleaching process. Results showed that, in bioleaching system with the co-inoculation of Acidithiobacillus thiooxidans TS6 and Acidithiobacillus ferrooxidans LX5 ( A. t + A. f system), the

- What are water treatment chemicals?
- 2. Water treatment chemicals – the full picture Water treatment chemicals are the solid core of water treatment processes. They became essential about a hundred years ago, after an expert panel discussion on the chlorination of potable water as a means of preventing waterborne diseases [ 9 ].
- What is the global market for membrane water treatment chemicals?
- Indeed, the global market for membrane water treatment chemicals was worth around USD 14.70 billion in 2015 and is expected to exceed USD 20.71 billion by 2025, with a CAGR of 7% forecast during the period 2017–2025 [ 16 ].
- Is the water treatment chemicals market a good business?
- The water treatment chemicals market is more diverse now, as it includes several new groups that entered the market place in the past 20 years. It surely represents good business for chemicals companies. Nevertheless, it might not be a good situation for human health and the environment.
- Should water treatment chemicals be added?
- The addition of water treatment chemicals has always been considered as a standard operation in water and wastewater treatment. The concentration of chemicals was usually kept to the minimum necessary to achieve a good quality of potable or otherwise treated water.
