To evaluate the lubrication properties of EnBio Mp46, it was compared with a hydraulic fluid formulated from phosphate esters, which exhibit excellent lubrication properties. One method of quantifying the relative lubricating properties of a fluid is to determine the coefficient of friction in a Ball-on-Disc test. The test results show that the ...
At Harnaschpolder wwtp phosphate removal from wastewater and sludge dewatering is optimised by dosing magnesium hydroxide to digested sludge. To optimise sludge dewatering and phosphate removal, a full-scale test has been executed since August 2015 using temporary equipment. In this test magnesium hydroxide is added to the ...
Considering that previous research has identified the nervous system as a sensitive target, Japanese medaka were used as an aquatic organism model to evaluate the developmental neurotoxicity of four OPFRs, including triphenyl phosphate (TPHP), tri‐n‐butyl phosphate (TNBP), tris(2‐butoxyethyl) phosphate (TBOEP) and tris(2‐chloroethyl) ...
A sensor based on molecular imprinted polymer (MIP) and a conductance transducer was developed for direct and label-free detection of phosphate in water. The sensor was able to measure the presence of phosphate in wastewater samples with good reproducibility, a linear range of 0.66–8 mg P L−1 and a lower detection limit of 0.16 mg P L−1. The ...
The oxidation of selected TrOCs and simultaneous flocculation of phosphates by ferrate was tested in batch experiments with secondary effluent from Berlin Ruhleben. ...
Miratech was given a quantity of tailings for bench-scale testing. Both Ciba and Hychem, Inc. provided the polymers. OBJECTIVES The objectives of the tests were to determine if this fine phosphatic clay material could be flocculated, captured, and filtered with the Geotube industrial fabric system. In addition, the other objectives were to ...
Suspensions of E. coli were first exposed to a low-pressure UV lamp in phosphate buffer to achieve 3 log inactivation, followed by an exposure to fluorescent light in NaCl solutions at the concentration of 1.0, 1.4, 1.9, 2.4 and 2.9 weight/volume %. When photoreactivation was completed in 3 h, survival ratio was recovered about 2 log in 1.0, 1.4, and 1.9% NaCl ...
The chemical studies show that the activated carbon samples contain large quantities of mineral ions, mostly calcium, sulphate and phosphate ions. The adsorption tests, attest of the suitability of the product use in the wastewater treatments.Keywords: activated carbon, coffee grounds, waste management, characterisation, adsorption, ash quantity, calcium, ...
Jar tests with synthetic water were carried out in order to investigate the effect of phosphate, bicarbonate and silicate on arsenic removal efficiency by in-situ formed ferric hydroxide. ...
One composite effluent sample was collected from each experiment and analyzed for pH, electrical conductivity, total suspended solids (TSS), total dissolved solids, dissolved oxygen, total organic carbon, nitrate, nitrite, and phosphate. Paired t tests at 1 and 5% levels of significance and project specific data quality objectives are used to compare water ...
The increasing trend over the last ten years to use waste water as a feed source for reverse osmosis membrane plant has resulted in an increase in calcium phosphate scaling on membrane surfaces. This is due to much higher levels of phosphate in waste water typically 10-30 mg/l as compared with a groundwater source which may have only 1-5 mg/l of ...
