This study investigates the effect of electrocoagulation contact time on pH and TSS wastewater discharged from treatment plant (WWTP) Psychiatric Hospital West Java Province. The experiment followed pretest-posttest control group design. involved testing 56 samples six times before after treatment. Each was repeated four times, there one for each repetition. tool used in this consisted 1-mm ele...

A pure yeast isolate Clavispora lusitaniae from whey beverage, phenotypically and molecularly characterized, was used to develop a reliable, controllable and reproducible technology for preparation of low alcoholic naturally carbonated beverage from guava var. Allahabad Safeda, Lucknow-49, Punjab Pink and its blends with lemon var. Baramasi under optimized fermentation conditions. The specific ...

In this study the effects of plant growth regulators including; GA3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (Perlette and Yaghuti). At the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and L/D ratio, flesh firmness, fresh weight, TA, pH, TSS and fruit color were ...

Pertambangan merupakan bidang usaha yang selalu menimbulkan dampak pada lingkungan. Salah satu negatif dari proses penambangan adalah timbulnya air asam tambang. Air tambang terbentuk karena kontak antara batuan sulfida dengan udara atau nilai pH rendah (pH < 4) dan memiliki logam terlarut tinggi. Nilai menyebabkan mudahnya logam-logam tertentu larut dalam air. Penelitian ini dilakukan di pe...

in this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). following treatments, fruits were stored at 0?c and 80 ? 2% relative humidity for 25 days. the weight loss, total soluble solids (tss), titratable acidity (ta)...

During a five-month summer period, samples of tertiary treated wastewater flowing in an extensive distribution system composed of storage tanks and pipes, were collected at two-week intervals from 21 different sampling points, including the exit from the wastewater treatment plant (WWTP). The WWTP producing this effluent treated wastewater from one of the most popular European tourist resorts o...

We have developed a simple, one-step procedure for the preparation of competent Escherichia coli that uses a transformation and storage solution [TSS; 1 x TSS is LB broth containing 10% (wt/vol) polyethylene glycol, 5% (vol/vol) dimethyl sulfoxide, and 50 mM Mg2+ at pH 6.5]. Cells are mixed with an equal volume of ice-cold 2 x TSS and are immediately ready for use. Genetic transformation is equ...

Introduction: The objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. Methods: This is an applied study. With regard to shiftwork schedules of the facto...
