To establish effective water quality monitoring strategies in estuaries, it is imperative to identify and understand the main drivers for the variation of water quality parameters. The tidal effect is an important factor of the daily and fortnightly variability in several estuaries. However, the extent...

The turbidity meter complies with EPA 180.1 and includes analytical quality assurance (AQA), which allows for adjustable calibration intervals, calibration record of turbidity standards used, and GLP-compliant documentation via PC and LIMS. Multiple deployment options to meet your project needs. Request...
Water-borne pathogen contamination in ambient water bodies and related diseases are a major water quality concern throughout the world. Pathogen contamination is a serious issue for almost all types of ambient water bodies, making its recognition and understanding essential (U.S. EPA [2012a]). Th...
for example, would not require potable quality water, such as washing the floors. The rainwater capture would also avoid rainwater runoff to “contaminate” the slurry, which is currently the case. This would also provide some relief, particularly during the winter months, of excess liquid slurry...
During the rainy season, water quality parameters tended to fluctuate dynamically, with the parameters of phosphate (PO4), nitrite (NO2), and total organic matter (TOM) exceeding the threshold value of water quality standards for aquaculture, with a PO4 value of 0.734 mg/L, a...

To provide basic basis and theoretical guidance for Pelteobagrus fulvidraco healthy breeding and the formulation of relevant industrial standards,from May to September 2018,the diversity index(H′),evenness index(J′),water quality transparency(SD),dissolved oxygen(DO)and ammonia nitrogen(NH4--N)of...
The characteristics of the water from the dam lake revealed an acceptable quality for most measured parameters with low chemical pollutants burden when compared with drinking water standards and water quality for aquaculture. However, high values of turbidity, colour, iron, manganese and microbial load...
