Sea Water Reverse Osmosis (SWRO)
Of the many water sources, such as water from rivers, springs, and also lakes, nothing is greater than sea water. More than 90% of the earth's surface is the ocean, which is a good alternative source of water for industries and settlements, as long as the water with high salt content can be treated properly. Along with the development of the times, humans have found technology to treat sea water ...

Cost comparison of seawater for toilet flushing and wastewater recycling
As freshwater resources are becoming increasingly scarce, unconventional sources of water should be given new consideration. In coastal cities, seawater, with minimal treatment, can be used for toilet flushing, reducing the demand for freshwater. Currently, it is practised on a large scale only in Hong Kong. This study estimates the cost of seawater flushing and compares it to the cost of ...

Study on performance of ultrafiltration membrane-based pretreatment for application to seawater reverse osmosis desalination
The objective of the work was to study at lab-scale the efficiency of hybrid process- coupling powdered activated carbon (PAC) adsorption or FeCl3 coagulation and UF- for marine organic matter removal. Regenerated cellulose membrane with 30 kDa and actual seawater from Mediterranean Sea were used. The coagulant was FeCl3 and adsorbents were two PAC types, with different surface area and pore size ...

Drinking water in Cuba and seawater desalination
The lack of drinking water has become a problem at world level because, in many places, supplies are very limited and, in other places, their reserves have been drained. At the present time there are estimated to be around two thousand million people that don't have drinking water for several reasons, such as drought, contamination and the presence of saline waters not suitable for human ...

Depth exposed membrane for water extraction (DEMWAX) for seawater desalination
Introduction The Depth Exposed Membrane for Water Extraction (DEMWAX) is a novel approach to both fresh surface water treatment and seawater desalination that deploys a system directly within the source water body. The DEMWAXTM system is configured to take advantage of the natural (free) pressure of the source water body to drive a membrane process. This configuration has many advantages over the ...

High performance boron removal from seawater by two-pass SWRO system with different membranes
Boron in the desalinated water produced by the seawater reverse osmosis (SWRO) system is one of the most challenging issues for drinking or irrigation water uses. In recent years, many post-treatment methods and designs for boron elimination have emerged and attracted lots of attention, but only a few cases have demonstrated high performance and economic efficiency. The main aim of this work was ...

Electrochlorination system: a unique method of prevention of biofouling in seawater desalination
Desalination plants require huge volumes of seawater for the generation of fresh water. Seawater contains large amounts of microbiological fluids which, when passed through the piping system, form biofouling in the inner surface of the pipeline, which results in the reduction of the flow rate of water without proper chemical treatment. Chlorine is the most commonly used disinfectant for water ...

Low cost processes for the removal of phosphates in water and wastewater
This paper presents a synopsis of various low-cost techniques employed for the removal of phosphates from water and treated wastewater. Techniques employed include seawater flocculation and coagulation/flocculation using bittern, adsorption on fluidised raw dolomite bed, and filtration through iron and aluminium coated filter media. Seawater flocculation at a seawater concentration of 10% ...

Nitrogen and phosphorus pollution alter the mutual relationship between corals and algae
phosphorus pollution change the relationship between the pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral. Nitrogen and phosphorus pollution change the relationship between the tropical coral ...

Boron removal by activated carbon and microfiltration for pre-treatment of seawater desalination
This study aimed to enhance boron removal through powdered activated carbon adsorption (PAC) and application of a micro-filtration (MF) process as a pretreatment of a seawater reverse osmosis (SWRO) process. Batch and continuous experiments were conducted to investigate the effect of membrane filtration as well as PAC addition on boron removal in reconstituted seawater. In batch test, two kinds ...

How Electrochlorination Systems Work to Prevent Biofouling
Water, water, everywhere: When you’re at sea, one of the most precious commodities you need to produce and protect is, somewhat ironically, clean water. Your offshore rig or vessel depends upon disinfected, pure seawater to keep all of your seawater utility systems running safely and efficiently. One way to ensure effectiveness and efficiency is to reduce or prevent any instances of ...

5 signs to tell when electrochlorination cells needs attention
When you’re planning maintenance for your offshore oil rig or another large vessel like an FPSO, the plans you’re likely most interested in are those that pertain directly to oil production (or your end goals). After all, those machines are the reason you’re in the water. It’s easy to see how the time you spend maintaining those machines is well worth every second. ...
