  • Drinking water treatment - understanding the processes and meeting the challenges

    On and follow Natural organic matter (NOM) derived from soil and vegetation in water catchments is the key factor influencing most, if not all water treatment processes. The structure of the NOM and its involvement in water treatment processes requires better understanding. It seems likely that a better understanding of NOM reactions could lead to far better predictive capacity for water ...

  • Aquatech supplies demineralized water treatment plant in madagascar

    The Facility Ambatovy, located in Madagascar, is a world-class, large tonnage nickel project that is positioned to be among the world’s biggest lateritic nickel mines. It is a lifelong project with an annual design capacity of 60,000 metric tons of nickel and 5,600 metric tons of cobalt. The site is located approximately 50 miles east of the capital of Madagascar, Antananarivo, and ...

  • Biohydrogen production from tequila vinasses using a fixed bed reactor

    In Mexico, the industrial production of tequila leads to the discharge of more than 31.2 million of m3 of vinasse, which causes serious environmental issues because of its acidity, high organic load and the presence of recalcitrant compounds. The aim of this research was to study the feasibility of a fixed bed reactor for the production of biohydrogen by using tequila vinasse as substrate. The ...

  • The influence of aeration on the change in corrosiveness and aggressiveness of groundwater

    A high concentration of aggressive carbon dioxide disturbs many technological processes in water treatment. It also causes the development of corrosion in steel and concrete. De-acidification of groundwater by means of air bubbles alters pH and the concentration of aggressive carbon dioxide. This was investigated for the variables of air flow (Q = 20–50 L h−1) and height of water ...

  • Rapid chemical oxygen demand analysis in soap and detergent manufacturing - Case Study

    Soap and detergent manufacturing generates waste water that is highly contaminated with organic compounds, significant concentrations of oil, grease, and surfactants. These compounds are a concern for receiving waters due to the formation of foam, and potential toxicity to microbial habitats and wildlife. Process water treatment typically involves dissolved air flotation, chemical ...

  • Drinking water quality control: control charts for turbidity and pH

    Water treatment processes are required to be in statistical control and capable of meeting drinking water specifications. Control charts are used to monitor the stability of quality parameters by distinguishing the in-control and out-of-control states. The basic assumption in standard applications of control charts is that observed data from the process are independent and identically ...

  • Design parameter estimations for adjustable bubble size in bubble generating system

    In this study, we developed a customized low cost and low energy bubble generator that can control bubble size. Hence, it can be used not only in the water treatment process but also in various other processes. This device was able to generate bubbles with a very simple system using only a general pump and a mixing chamber. Increasing the number of partition walls in the mixing chamber reduced ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...

  • Simulation of NOM events in pilot plant evaluation of DAF/Ozone/BAC for drinking water treatment

    Pilot plant testing is invaluable for ascertaining the robustness of water treatment processes against raw water quality events such as turbidity and colour spikes, whether it be for stress testing of an existing process or designing of a new process. Unfortunately, the natural occurrence of such events (particularly colour) can be difficult to predict and commercial humic materials generally ...
