What is TDS?

by Camlab Limited  (May 30, 2015)

Answer: Total Dissolved Solids (TDS) is a measure of the combined content of all the inorganic and organic substances such as mobile charged ions, minerals, salts or dissolved metals in a volume of liquid. Normally TDS is used in water testing, where TDS is defined as anything present that is not pure water (H2O) molecule ...

Efficiency and reliability of membrane processes in a water reclamation plant

by IWA Publishing  (Jun. 26, 2015)

Performance of a water reclamation plant using ultrafiltration (UF) and reverse osmosis (RO) treating 280,000 m3/d of wastewater was evaluated over 1 year. Statistical analyses were performed on flow rate, temperature, pH, total suspended solids (TSS), total dissolved solids (TDS), biochemical oxygen demand (BOD5) and total coliforms. Variations ...

Cape Preston Project - The first Pre-Assembled Large-Scale Desalination Plant case study

by IDE Technologies  (Jun. 24, 2015)

The Cape Preston desalination plant is the world’s first large-scale desalination plant that was pre-assembled elsewhere due to the remoteness of the location. It provides high quality clean water to CITIC Pacific Mining’s Sino Iron project, overcoming a number of extraordinarily difficult environmental challenges. ...

Enhanced nitrogen removal with an onsite aerobic cyclic biological treatment unit

by IWA Publishing  (Jun. 12, 2015)

Coastal Zone Act Reauthorization Amendments (CZARA, Section 6217) necessitate the requirement that onsite wastewater disposal units located near impaired surface waters or groundwater to provide at least 50% nitrogen removal. Approximately 38% of Hawaii households use onsite systems including septic tanks and cesspools that cannot ...

Point-of-use chlorination of turbid water: results from a field study in Tanzania

by IWA Publishing  (Jun. 8, 2015)

Household-based chlorine disinfection is widely effective against waterborne bacteria and viruses, and may be among the most inexpensive and accessible options for household water treatment. The microbiological effectiveness of chlorine is limited, however, by turbidity. In Tanzania, there are no guidelines on water chlorination at household ...

Anaerobic biological treatment of methylparaben in an expanded granular sludge bed (EGSB)

by IWA Publishing  (Jun. 3, 2015)

This study evaluated the behavior of an anaerobic expanded granular sludge bed system using different methylparaben (MPB) concentrations. The assay was conducted for 268 days and was divided into seven stages of operation, which included the starting stage and subsequent stages where the MPB concentration was increased. The inoculum that was ...

An investigation into the effectiveness of sand media amended with biochar to remove BOD5, suspended solids and coliforms using wetland mesocosms

by IWA Publishing  (May 18, 2015)

Constructed wetland ecotechnologies (CWEs) are a promising solution to effectively treat domestic wastewater in developing countries at low cost. This paper reports the findings of the effectiveness of sand media amended with woody biochar and two plants species (Melaleuca quinquenervia and Cymbopogon citratus) in removing biological oxygen ...

Treatment performances of French constructed wetlands: results from a database collected over the last 30 years

by IWA Publishing  (May 7, 2015)

Approximately 3,500 constructed wetlands (CWs) provide raw wastewater treatment in France for small communities (<5,000 people equivalent). Built during the past 30 years, most consist of two vertical flow constructed wetlands (VFCWs) in series (stages). Many configurations exist, with systems associated with horizontal flow filters or ...

Experimental study on non-woven filamentous fibre micro-filter with high filtration speed

by IWA Publishing  (May 7, 2015)

A laboratory study was undertaken to pursue the filter performance of a micro-filter module employing highly porous fibre media under a high filtration rate (≥1,500 m/day), faster than that of any conventional filter process. The effects of filtration rate, head loss, raw water turbidity, and filter aid chemicals on filter performance ...

Characteristics of suspended solids affect bifenthrin toxicity to the calanoid copepods, Eurytemora affinis and Pseudodiaptomus forbesi

by John Wiley & Sons, Ltd.  (May 2, 2015)

Bifenthrin is a pyrethroid pesticide that is highly toxic to aquatic invertebrates. The dissolved concentration is generally thought to be the best predictor of acute toxicity. However, for the filter feeding calanoid copepods, Eurytemora affinis and Pseudodiaptomus forbesi, ingestion of pesticide‐bound particles could prove to be another route ...
