Inadequately treated or untreated wastewater greatly contribute to the release of unwanted toxic contaminants into water bodies. Some of these contaminants are persistent and bioaccumulative, becoming a great concern as they are released into the environment. Despite the abundance of wastewater treatment technologies, the adsorption method overall has proven to be an excellent way to treat
Depending on the sources, the dye waste effluent varies considerably in color, suspended solid content and COD concentration. The dye waste effluents collected for the present experiments varied in color from purple, dark red, brown, grey, dark blue or black. The COD concentration went from 300 to over 2000 mg/l.

The reduced natural waters and the large amount of wastewater produced by textile industry necessitate an effective water reuse treatment. In this study, a combined two-stage water reuse treatment was established to enhance the quality and recovery rate of reused water. The primary treatment incorporated a flocculation and sedimentation system, two sand filtration units, an ozonation unit, an

Chrysoidine is a type of industrial azo dye and a well-known toxicant. Due to its good dyeing characteristics, it is widely used for dyeing leather, paper, feather, grass, wood, bamboo, etc. Hence, it is very important to remove or reduce its concentration below the contamination level in the waste line by using low-cost technologies. Sawdust is a plentiful material available very cheaply from
Textile dyeing industry an environmental hazard
Specific water consumption for dyeing varies from 30 - 50 liters per kg of cloth depending on the type of dye used. The overall water consumption of yarn dyeing is about 60 liters per kg of yarn. Dyeing section contributes to 15% - 20% of the total waste water flow.

Precise closure of single blood vessels - Science Advances
We report a novel approach to selectively close single blood vessels within tissue using multiphoton absorption–based photothermolysis (multiphoton photothermolysis) without the need of exogenous agents. The treatment process is monitored by in vivo reflectance confocal microscopy in real time. Closure of single targeted vessels of varying sizes ranging from capillaries to venules was
Through this final recommendation, the U.S. Public Health Service (PHS) updates and replaces its 1962 Drinking Water Standards related to community water fluoridation—the controlled addition of a fluoride compound to a community water supply to achieve a concentration optimal for dental caries prevention. 1 For these community water systems that add fluoride, PHS now recommends an optimal
Antibiotic resistant bacteria and resistance genes
Even though the 16S rRNA gene abundance in the processed waste water was five times higher (2.5 × 10 6 ml −1), the treatment plant had little effect on the in-river abundance at site B (Fig. 2, left plot). This was in agreement with expectation, considering that the plant’s effluent was diluted by factors of 1:25–1:65 upon mixing
However, Martin Dye, senior district officer in the environmental department of Wolverhampton City Council says that this figure is "a little short of the mark", and explains that the Wolverhampton local authority has sites that were taking waste in the mid 1950s, and which are still capable now of producing enough gas to burn.
- Which is the most popular drilling polymer for oilfield industry?
- PARTIALLY HYDROLYSED POLYARYLAMIDE (PHPA) manufactured by GDFCL at its ISO Certified manufacturing Facility in Gujarat, one of the most Popular Drilling Polymers for the Oilfield Industry PHPA is a co-polymer of anionic character and high molecular weight.
- Are PHPA drilling polymers eco-friendly?
- Key Features and Benefits: Chemtex's PHPA Drilling Polymers when tested for its toxicity level, were found eco-friendly and when compared to its contemporaries such as Bentonites ( Al2H2O6Si). They may not be hazardous to soil but is highly toxic to aquatic life and hence do not find its use in sites beside water bodies.
- What is partially hydrolyzed polyacrylamide (PHPA) based high molecular weight drilling polymer?
- Partially Hydrolyzed Polyacrylamide (PHPA) based high molecular weight drilling polymer for use in controlling of fluid loss and increasing drilling mud viscosity and removal of colloidal from deep drilling foundations such as diaphragm walls, piling concretes, etc.
- Is PHPA a water soluble polymer?
- PHPA is a co-polymer of anionic character and high molecular weight. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, Viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems.
