Abstract Wastewater from the production of meat and bone meal, due to high load organic matter suspended solids, is a significant problem in process its treatment. In this work, we examined method treating wastewater using coagulation with hydrogen peroxide Fenton process. Treatment variants included use variable Fe 2+ /H 2 O ratios 1:5–1:30, doses 3–18.0 g/L H , 5–10 mL/L coagulant PIX 113. Th...

Introduction: The most important environmental problem of automotive industries is the produced wastewater due to its various processes. The flocculation and coagulation along with chemical sequestration are among important processes for removing contaminants from wastewaters. The aim of this study is to investigate the efficiency of coagulation and flocculation process along with chemical sequ...

Abstract Dug well water is one of the clean sources used in Kubu Raya Regency. However, through initial testing, physical and chemical qualities were inadequate to meet hygiene sanitation demands daily living following Regulation No. 32 Minister Health Indonesia 2017. Consequently, objective this study was examine treatment dug by electrocoagulation electrocoagulation-coagulation employing Poly...

Arsenic is a carcinogenic metalloid that is currently regulated in drinking water. The levels of arsenic in finished water in an existing water treatment plant are exceeding the current regulation of 10 μg/L. One of the available technologies for arsenic removal from groundwater is adsorption onto coagulated flocs and in this field, ferric chloride is the most commonly used coagulant for arseni...

scarcely pharmaceutical applications. Recent investigations state its utility in dissolution enhancement of poorly soluble drugs, amorphous state stabilization and extended drug release. To broaden the applications of MC as a pharmaceutical excipient, need has been felt to test its antigenicity owing to its proteinic nature. In silico antigenicity screening has been carried out to enable its us...

BACKGROUND Previous studies showed that heparin's anti-allergic activity is molecular weight dependent and resides in oligosaccharide fractions of <2500 daltons. OBJECTIVE To investigate the structural sequence of heparin's anti-allergic domain, we used nitrous acid depolymerization of porcine heparin to prepare an oligosaccharide, and then fractionated it into disaccharide, tetrasaccharide, ...

BACKGROUND Laparoscopic prostatectomy (LRP) may activate clotting system influencing the risk of perioperative thrombosis in patients with prostate cancer. Moreover, different anaesthetic techniques can also modify coagulant factors. Thus, the aim of this study was to investigate the effects on pro- and anti-coagulant and fibrinolytic factors of two established types of anaesthesia in patients ...

hlorine is the most widely used oxidant in the United States for water disinfection. But chlorine reacts with the natural organic matter (NOM) that remains after treatment and forms halogenated by-products. Only some of these by-products have been identified, such as trihalomethanes (THMs) and haloacetic acids (HAAs), which are suspected to be human carcinogens. In 1979 the US Environmental Pro...

In this work, the effectiveness of removing colour and total suspended solid (TSS) from complex organic particulate artificial sewage (COPAS) via coagulation process was studied. Organo-floc (OF), a tannin-based coagulant derived plant used as coagulant. OF applied in jar test experiment at various dosages 57 rpm for 5 min, 30 min sedimentation time to find out optimum dosage TSS removal. Zeta ...
