Water Quality Testing
1) Water quality analysis

Chromaticity, turbidity, smell and taste, visible matters, pH, conductivity, total hardness, total dissolved solids, acidity, alkalinity, temperature, suspended solids, sodium ion, potassium ion, lithium ion, calcium ion, magnesium ions, fluorides, chlorides, bromides, nitrates, sulfates, nitrites, carbon dioxide, carbonates, bicarbonates, boron, iron, chromium, lead, manganese, strontium, barium, silver, cadmium, aluminum, copper, nickel, zinc, mercury, cyanides, arsenic, selenium, free residual chlorine and total chlorine, phosphates, silicates, ammonia nitrogen, organic carbons, total nitrogen, total phosphorus, Kjeldahl nitrogen, biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, total bacteria count, total coliforms, thermotolerant coliforms, Escherichia coli and more.

2) Organic compound analysis

Qualitative and quantitative analysis conducted by gas chromatography, liquid chromatography, UV spectroscopy, infrared spectroscopy and other means.

3) Membrane and membrane module detection

Detect indicators of micro-filtration membranes, ultra-filtration membranes, electro-dialysis membranes, reverse osmosis membranes and modules.Indicators include membrane mechanical strength, surface roughness and uniformity, leak detection, bubble point pressure, trans-membrane pressure, maximum membrane pore size, average membrane aperture, air flux, amount of porosity, work pressure, hydro-philicity, water content, molecular weight cut-off, water flux (including pure water flux and load flux), retention, stain resistance performance, oxidation resistance, acid-alkali resistance, sludge loading, antibacterial property and more.

Investigate membrane failures (including membrane fouling), arrange cleaning and make improvements.
