this study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. this experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. the influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...

The liquors were found to be adulterated with impure water from different sources. The measurement of pH, chloride concentration, total dissolved solid, total suspended solid and heavy metals reveals the adulteration in liquors. The duplicate brands contain rectified spirit, caramel, coloring agents, flavoring agents and essential oils which are not according to specifications. The adulterated ...

Feed water that need to be pre-treated before using methods such as, microfiltration, Ultrafiltration, nanofiltration and reverse osmosis is characterized by containing turbidity, bacterial content and total dissolved solid which causes fouling and scaling in membrane performance. Thus, it is necessary to develop a method which is cost effective. Pre-treatment has been shown as a good method to...

Pharmaceutical and personal care products (PPCPs) industries suffer inadequate effluent treatment due to the presence of recalcitrant substances, insufficient carbon source and nutrients. Biodegradation is the ability of microorganisms to metabolize pollutants in soil, sediment and water environment. There is great awareness in the positive impact that microorganisms play in protecting environm...

Acid (pH) and Total Dissolve Solid (TDS) are the two most important factors of many parameters that must be considered to maintain water quality in Aquascape. A good normal pH for plant life Aquascape is 6.8 a TDS aquascape below 150 ppm. This study aims design an IOT system aquascapes. In this using fuzzy method as controller determinant added value acid or wet aquascape. The set between 6.5-7...

Hydroponics is a way of farming that does not use soil, but only uses water contains nutrients. The growth hydroponic plants can be influenced by various factors, one which lack nutrition in plants. Therefore, this study aims to create system functions control nutrition, as well the availability sufficient reservoirs. This process NodeMCU esp8266 and processes sensor data then sends it firebase...

Thin-film composite nano-filtration (NF) and reverse osmosis (RO) membranes based NF followed by ROpilot plant at a feed pressure of 20 atm.and flow rate of 10 L/min. was used to remove colour, total dissolved solid (TDS) and chemical oxygen demand (COD) of distillery spent wash. NF was found to be effective for high rejection of TDS, colour and COD by 85%, 99% and 95%, respectively. Furthermor...
