Titanium Dioxide Wastewater
Titanium Dioxide Wastewater A large amount of waste acid is produced in the production of titanium dioxide, a large amount of high-salt wastewater is generated in the post-treatment process, and some titanium dioxide is still lost after the CN filter. On the one hand, the titanium white industry suffers from increasingly strict Environmental constraints, on the other hand, waste acid, water, and ...

Should We Be Concerned About Disinfection Byproducts?
Chlorinating water can lead to the formation of harmful compounds, but there are treatment alternatives Water utilities often chlorinate drinking water to kill pathogens that could pose a risk to human health. However, when chlorine is used to treat water, it can cause a chemical reaction with natural inorganic or organic compounds, which may be derived from decaying plants, algae, or animal ...

Trihalomethane reduction in drinkable water by controlled chlorination and use of hydrogen peroxide
The reduction of trihalomethane (THM) formation in the water treatment process by a controlled chlorination of ammonia and successive quenching with hydrogen peroxide has been studied. The optimum values of the process parameters have been determined with a calculation programme that makes use of the kinetic constants determined with the water to be treated. The obtained data have been verified ...

Evaluation of ultrasound technology for the disinfection of process water and the prevention of biofilm formation in a pilot plant
In this study, we investigated the use of ultrasound for the disinfection of process water as an alternative for more traditional techniques, like chlorination and UV-irradiation. A pilot plant was constructed to mimic circulating process water in industrial environments. The disinfection efficiency of ultrasound was assessed and compared to UV-treatment and chlorination. In addition, the ...

Aeration decreases THMs
WITH HIGH LEVELS of trihalomethanes (THMs), the township of North Shore in Northern Ontario, Canada, explored treatment options at its Serpent River'Water Treatment Plant. The Serpent River treatment process includes slow-sand filtration. limestone contact tanks, and sodium hypochlorite disinfection. After filtration, sodium hypochlorite is injected into the treatment process before water enters ...

Clarifiers-No, Filtration-Yes: A Case Study
Problem Twenty miles southeast of Coos Bay, Oregon situated at the conjunction of the North and South Forks of the Coquille River lays the town of Myrtle Point. Just five years ago this community of 2670 residents was facing a large potable water problem with an even larger price tag. The town feeds its water treatment plant from the North Fork Coquille River. Prior to the 1990s the water ...

Chlorine removal with KDF 55 - Case Study
KDF 55 Process Medium Helps with Removing Chlorine in a Municipal Water Treatment Facility A Los Angeles-based maker of fashion jeans uses KDF media instead of chemicals for removing chlorine when treating municipal water in their stone-washing process. High-purity copper-zinc redox water filter media consistently provides 99% of free chlorine removal from water by electrochemically reducing ...

Victor Project – De Beers Canada, Ontario case study
In early 2006 De Beers Canada began the construction of its first Ontario diamond mine, in the James Bay Lowlands. To provide drinking water for this mining camp and its daily workforce of nearly 1,000 , the engineering- consulting firm AMEC recommended that De Beers Canada call on the expertise of H2O Innovation. H2O presented a solution that matched its client's very special needs and ...

Minimizing microbial risk in the beverage industry through hygienic design
When producing any food or drink it is important to make every effort to minimize microbial risk, and make products for human consumption as safe as possible. Any microbial contamination is taken extremely seriously, and can result in costly product recalls in response to fears for human health. In addition to the serious health risks from certain bacterial species, contamination with less ...

Replacing chlorine water treatment With Alstasan Silvox
Water Treatment, a chain of process carried out to purify water with different desired end results. These include physical as well as chemical means. Visible impurities can be removed through physical means like filtration, sedimentation and decantation but problem arises for invisible pathogenic organisms which can only be removed through chemical addition. Various advanced chemical technology ...

San Joaquin Valley California - Arsenic removal from ground water
Background The San Joaquin Valley of California is approximately 220 miles long and varies in width to a maximum distance of approximately 80 miles. The occurrence of groundwater over the entire extent of the valley is abundant. Recharge for the varied depths of aquifers is from precipitation in the form of rain and the snow pack from the western Sierra Nevada Mountain Range. High capacity wells ...

Park City, Utah Arsenic removal from ground water
Background Park City Utah Water, which serves a population of 6,500, has five water sources. Spiro Tunnel and Spiro Portal are two that were in need of Iron and Manganese removal as well as above limits for Arsenic. Filtronics was engaged by the engineering firm of Eckhoff, Watson and Preator (EWP), Salt Lake City, to perform pilot tests for the Park City Municipal Corporation. The purpose of ...
