Matt Michel: 13 signs of water treatment opportunities

Most plumbers are missing a golden opportunity for add-ons with point-of-use or whole-house water purification systems and/or water softeners. Consumer awareness of the benefit of water purification has been raised by the pandemic and well-publicized municipal failures. Many, if not most consumers are highly sensitive to contamination today, whether air- or water-borne.

New wastewater treatment technology to produce less sludge

A major environmental challenge for wastewater treatment is the disposal of excess sludge produced during the process. The LIFE Perbiof project has been developing and testing a technology that will help to overcome this challenge. Results demonstrate it can perform highly effective treatment of municipal wastewater (removing 80% of the organic content) while producing low levels of sludge.

Closing the water cycle: new wastewater treatments are tested

Managing wastewater treatment at the river-basin scale

The EU Water Framework Directive1 requires policymakers to consider the management of water e.g. in rivers, lakes and streams, at the scale of the river basin, but can wastewater treatment systems be managed at the same scale? To help policymakers answer this question, a team of Spanish researchers have created a method for assessing the integrated operation of wastewater treatment plants in a river basin. Uniquely, the method considers both local and global environmental factors and an economic assessment.

Wastewater treatment plant discharges can promote the development of antibiotic resistance in streams

Biodegradation of PPCPs in wastewater treatment plants — a Danish case study

The non-restricted production and use of pharmaceuticals and personal care products (PPCPs) has led to their presence in effluents from treatment plants, which can pose a threat to aquatic organisms downstream. This study analysed the breakdown of six common chemicals in four Danish treatment plants. The findings shed new light on the factors affecting removal of PPCPs from waste, showing that the composition of waste is more important than the design of the treatment plant.

Separate waste-water treatment of urine could have lower environmental impact than centralised, combined waste-water treatment

Municipal wastewater is a major source of pharmaceuticals in the aquatic environment. Results from a recent study suggest that collecting and treating urine separately from other forms of sewage could be a cost-effective way to reduce the harmful effects of pharmaceuticals on the environment, while also providing a source of nutrients for fertilising agricultural crops.

UV water treatment may increase antimicrobial activity of linezolid antibiotic

UV treatment does not always turn hazardous water pollutants into harmless substances. Recent lab tests suggest that the toxicity of the antibiotic linezolid to microorganisms appeared to increase post-treatment. This research did find, however, that UV treatment successfully reduced the antimicrobial activity of four other antibiotics tested, plus four artificial sweeteners.

New energy-positive waste-water treatment process uses just 15% of the energy required for current alternative

Conventional municipal waste-water treatment processes are based on aeration, which is energy intensive. Now, researchers have developed an alternative waste-water treatment process. In addition to avoiding the use of aeration in favour of filtration/biofiltration and encapsulated denitrification (the application of capsules containing nitrifiers, which convert ammonium into nitrate), the process also uses waste biosolids to generate electrical energy. The process has been tested in a pilot facility and found to require just 15% of the energy required for conventional approaches. Moreover, the process is energy positive, as the biosolids are able to generate more than enough energy to power the treatment plant. If this technology could be scaled up to the municipal level, it could significantly reduce the energy use and environmental impacts of waste-water treatment.

Synthesis of sequestration resins for water treatment in light water reactors

An organic synthesis of materials to achieve removal of low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions. The synthesis includes the steps of providing a cation exchange resin, functionalizing the cation exchange resin using a chloride intermediate to form a sulfonyl chloride resin, and reacting a multi-amine based ligand with the sulfonyl chloride resin to form a sequestration resin. The synthesis further includes the steps of cooling the sequestration resin, and washing and drying the sequestration resin.

BALLAST WATER TREATMENT DEVICE

A ballast water treatment device attached to a vessel provided with: a line (1) through which drawn treatment target water flows; and a ballast tank (5) connected to a downstream side of the line (1). The ballast water treatment device is provided with: a filter (3) which is disposed in the line (1) and which filters the treatment target water; and a controller (7). The controller (7) causes the treatment target water to be discharged outboard from an upstream side of the filter (3) in an early stage of drawing of the treatment target water, until water quality is stabilized, and, when the water quality of treatment target water has stabilized, causes the filter (3) to filter the treatment target water. Thus, ballast water filtering can be efficiently performed.

WATER TREATMENT METHOD AND WATER TREATMENT APPARATUS EACH USING MEMBRANE

Ozonated washing water is generated by injecting an ozone gas into pressurized washing water that is filtered water obtained by membrane filtration of untreated water and that is to be used at the time of backwashing, and the ozonated washing water is supplied to a membrane from the filtration secondary side to thereby remove a fouling substance inside the membrane, while causing ozone-containing bubbles to emerge in the filtration primary side to thereby remove a fouling substance on a membrane surface in the filtration primary side.
