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.

Abacus Plumbing's whole-house carbon water filtration, softener and reverse osmosis equipment can dramatically reduce water contaminates.

“Water quality has grown 300% across the U.S. since the pandemic began,” says Glen Blavet, founder and CEO of HALO Water Systems. “People are at home, and they’re looking to improve their quality of life and their health, so they’re looking at the water they’re drinking out of the tap.”

My technical boiler books all use the “lessons learned” theme, and the following are the lessons I have learned about boiler water treatment.

The Orange County Sanitation District in Huntington Beach, California provides wastewater collection, treatment, and disposal services for approximately 2.6 million people. They had a combination of loud industrial equipment, cavernous space, and highly reflective surfaces creating an acoustic nightmare.

Employees working at water treatment plants face danger every day. The work is inherently treacherous, as water makes every step potentially hazardous, and sometimes even life-threatening.

This document compiles information on the current methodologies, tools and models and helps readers identify appropriate models/ and methodologies for estimating substance-specific removal/emissions from wastewater treatment systems. It could support efforts to improve these models and tools.

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.

A new study has indicated that, although greywater treatment and re-use could produce water savings of up to 37 per cent, it could not comprehensively remove hazardous substances. Complementary measures are needed, such as eco-labelling and regulatory controls.

A new review from Romanian researchers has summarised current and emerging methods for cleaning up contaminated land and water. It highlights the need for more consistent testing, reporting and evaluation of different remediation techniques.

Industries, such as paper production, require large amounts of water which can drain vital supplies of fresh drinking water. Researchers working towards the ultimate goal of ‘closing the cycle’ by re-using industrial water onsite have now identified innovative new treatments for wastewater from a paper mill.

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.

A comprehensive analysis of pharmaceuticals in Spanish wastewater has indicated that they are widespread pollutants. The majority of pharmaceuticals present in incoming wastewater were still present in both treated water and in the river waters receiving the treated water.

A new study has evaluated disinfection by-products (DBPs) formed during the treatment of ballast water. As some of the DBPs produced are hazardous, the study concludes that more information is needed to ensure DBPs from treatment methods do not harm human health or aquatic environments.

Widespread use of antibiotics has led to pollution of waterways, potentially creating resistance among freshwater bacterial communities. A new study looked for antibiotic resistance genes in a river basin in Spain, revealing that wastewater discharges can promote the spread of antibiotic resistance in streams and small rivers.

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.

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 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.

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.

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.

A method of produced water treatment in an in-situ recovery method of producing bitumen from oil sand, the method has the steps of: separating bitumen from bitumen-mixed fluid so as to leave produced water, the bitumen-mixed fluid having been recovered from the oil sand wells; and filtering the produced water via a microfiltration membrane made of polytetrafluoroethylene.

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.

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.

A thermo-sensitive water absorbent is used as a draw material in production of fresh water by a forward osmosis process. The thermo-sensitive water absorbent has a cloud point, and coagulates when heated, the thermo-sensitive water absorbent being a block copolymer containing at least a hydrophobic part and a hydrophilic part, having a glycerin structure as a basic structure, and including an ethylene oxide group and a group consisting of propylene oxide and/or butylene oxide.
